Chapter 67 The Initial Success of the X-ray Machine Imagine computer applications

Zhang Zhimu wanted to take the elevator to Yang Chang's office upstairs, but as soon as he entered the elevator, he saw Master Qingfengzi with a few people in the elevator.

"Oops! Mr. Zhang, did you also go to see Yang Chang's X-ray machine? Qingfengzi asked when she met.

"No!" Zhang Zhimu said, "I just finished watching their TV set. I want to go to Yang Chang's place to sit, how did their X-ray machine get it? ”

As soon as the elevator door opened, Qingfengzi said, "Let's go!" Just go check it out! ”

Zhang Zhimu followed Qingfengzi and them to a laboratory upstairs. It just so happened that Yang Chang was also here, and he was talking to everyone. Seeing Zhang Zhimu and Qingfengzi coming in together, he immediately greeted him and said, "Mr. Zhang, I'll call your office, Miss Yang said that you came to me, and I haven't seen you." I didn't expect you to come with Master Qingfengzi. ”

"We met in the elevator," Mr. Zhang said, "and I was in the lab where I was doing TV, and I watched their TV for a while." ”

"Oh! I mean, the other day they said that TV is making a lot of progress! Yang Chang said.

"I just watched it, and I think it's already good!" Zhang Zhimu said, "You can let them produce a batch first, and we will try to use it." Only the process used can find the problem. ”

"Good! The furnace front of their smelting plant and the boilers of the power plant need to be monitored by television. Yang Chang said, "I'll let them make some protective shields and give them a trial first." In the future, it will be used in many places that are not suitable for people to see. ”

"I'm looking for you to ask, how is the radio transmission and receiving equipment doing?" Zhang Zhimu asked as he sat down.

"Some people have already started to do this, and their TVs can be experimented with if they are good." Yang Chang said, "However, I didn't make much progress in letting them make a tape recorder to record TV signals. ”

"Take a look at your X-ray machine today, and I'll talk to you about the VCR when I have time. You can't do it with a tape recorder. Zhang Zhimu said, "Show us your X-ray machine!" ”

Yang Chang said, "Wait a minute! It's time for them to go to develop the film and come back! ”

After a while, several people hurriedly ran over with the film that had not yet dried, and as soon as they came in, they said to Yang Chang, "Great! That's great! Clearer than ever! As soon as he looked up and saw that Zhang Zhimu and Qingfengzi were there, he was a little embarrassed, and immediately said, "Mr. Zhang is here!" See how clear our X-ray negatives are? ”

Zhang Zhimu and Qingfengzi both got up. These people holding the film, pointing the film to a few fluorescent lamps, the film took a clear image of the bones of the human hand, and some of the bones of the human foot, and the larger one was a picture of the entire ribcage of the person.

Zhang Zhimu immediately said to Yang Chang: "Hurry up and call and ask Zhang Bengui and Zhang Bingchen to come over!" By the way, I also invited Lu Wenchen over! ”

Qingfengzi looked very happy and said, "They told me some time ago that they couldn't get any images. I came here once and found that the film was completely white. I know it's the light that's too strong. Ask them to turn it down a little bit and then the image comes out. ”

The team leader who did the X-ray said: "No way, we can't see this X-ray, and we don't know how strong or weak it is." ”

Zhang Zhimu suddenly remembered and asked, "I asked you to wear lead protective clothing and lead glass eyes, do you all bring them?" ”

"Bring it! Bring! The team leader said, "Sometimes, sometimes I am in a hurry, and sometimes I forget." But that's fine! ”

"If there's a problem, it's over!" Zhang Zhimu said sharply, "I have repeatedly told you that you can't play child's play, why don't you listen!" This thing can't be seen or touched, but it does a lot of harm to people. In the future, if I find that any of you are not paying attention, I will definitely not let him do this work. ”

The team leader didn't expect that Zhang Zhimu would see this matter so seriously, and hurriedly said: "Don't worry, Mr. Zhang, we must pay attention!" ”

Zhang Zhimu said: "You immediately make a screen with fluorescent materials, and X-ray irradiation can make fluorescent materials shine. This makes it possible to display the image on a fluorescent screen based on the intensity. As long as the X-rays are not very strong, a short period of exposure will not be a major problem. Through this method, we can give people a medical examination, and we can also inspect the metal parts we weld to see if there are any hidden dangers in the weld. ”

Yang Chang suddenly said: "Can you use the TV method to see this X-ray image, if so, will the person who uses X-ray be much less exposed?" ”

"Of course, the next step is to work with the TV people to solve this problem together." Zhang Zhimu said, "In the future, X-ray examination will be our most routine examination. X-ray doctor to protect well! ”

Zhang Bengui and Zhang Bingchen arrived together with a few people, and as soon as they came in, Zhang Bengui shouted: "Zhimu! Why do you want us to rush over in such a hurry! ”

Zhang Zhimu didn't answer Zhang Bengui's words, and said to the leader of the X-ray team: "Show them!" ”

The people who were engaged in X-rays held the film in front of the fluorescent lamp again, Zhang Bengui took out his reading glasses and leaned over, and Zhang Bingchen and several people who came with them also surrounded him. Zhang Bengui in the crowd exclaimed: "Oops! How did you get this thing, is it really a human hand? ”

Zhang Zhimu smiled and said, "Hehe! Show them the feet again! ”

changed the film, Zhang Bingchen said: "What a foot bone! ”

"And whatever!" Zhang Zhimu said again.

"Oops! It's the sternum! Zhang Bingchen said, "Oops! How did you get it? With this thing, it will be much more convenient to see a doctor in the future! ”

Zhang Zhimu said to Zhang Bengui, who had just straightened his waist: "How is it?" Uncle Zhang! Is it worth it to ask for a trip with this! ”

"It's worth it, it's worth it! It's worth it! Zhang Bengui came to you and said, "Tell me how you got this thing?" ”

Zhang Zhimu said to the team leader who was engaged in X-rays: "Let's do some science popularization work for them!" ”

The team leader simply explained the principle of X-ray to Zhang Bengui and Zhang Bingchen.

Zhang Bengui said: "Zhimu! I have been engaged in orthopedics all my life, and I have relied on my hands and experience. But with this thing, you can see the bones clearly, and it will be much easier to heal the disease! ”

Zhang Bingchen also said: "That's right! In the future, the bones are not right! It's clear at a glance, and you can see it clearly if it's long or not! ”

"Not only that, but in the future, a chest examination of the patient can be performed to see if there is a shadow in the lungs and whether there is a shadow in the liver. It is also the most effective means of checking the internal organs. Including whether there is a tumor in the brain can be seen! Zhang Zhimu said, "With this kind of means, we can improve the level of disease inspection by a big step!" In the future, how to use and use X-ray examination, you should also arrange special people to do this. ”

Without waiting for Zhang Bingchen to speak, Zhang Bengui said: "Zhimu, I'll talk about the rest later." Hurry up and get one of these for our hospital first, and my orthopedic department will be able to use it right away. ”

Zhang Zhimu smiled and said, "Uncle Zhang! It's useless if you're in a hurry! It also takes time to produce something that will work for you. If I give it to you, you won't use it. You need to arrange for a special doctor to come here and learn from them. ”

After listening to Zhang Zhimu's words, Zhang Bingchen turned around and said to the four people who came with them: "You four, you will come here to work from tomorrow, and you must learn from others with an open mind." Learn how to use this stuff. ”

Yang Chang laughed when he heard this, and said, "I said that you are really in a hurry to become like this!" We've just been able to take pictures, but a lot of things are not perfect! ”

Zhang Bengui said: "You little thing! Don't know that there are many patients in our hospital every day? With this thing, they can suffer less. We don't need you to be too perfect, just take pictures! "Zhang Bengui's qualifications in Yaogang are very old, and when he said Yang Chang, Yang Chang didn't dare to say anything.

Zhang Zhimu played a round and said: "In this way, Yang Chang, you will make an X-ray machine that can be easily used for them as soon as possible, and you will slowly improve it in the future." Also, you need to use daylight behind frosted glass to make a light box where you can easily view the film for the doctor to use. We can't see clearly at the light like this. ”

When Lu Wenchen came in, he was a little strange when he saw that Zhang Zhimu and they had so many people here. Seeing Lu Wenchen coming, Zhang Zhimu only asked Lu Wenchen to show X-ray photos. Lu Wenchen was also surprised after reading it, and when he saw Zhang Bengui and Zhang Bingchen here, he said, "Oops! With this stuff, it's much easier to see a patient! ”

Zhang Zhimu said to Lu Wenchen, who had just sat down: "Please come, don't talk about seeing a doctor." I want to tell you that in the future, the welds of the boilers and steel-hulled ships that you have welded will be X-rayed. If there is any missing soldering or false soldering, it can be checked out with X-ray. Wouldn't this be much more secure? ”

"Oops! That's great. Lu Wenchen was happy to hear this, "Mr. Zhang, what I'm most worried about is the weld of the high-pressure boiler. Sometimes I feel like I'm gambling. I don't know how the welding is done after welding. If there is a serious deficiency, it is easy to have an accident. It would be great to have such means in the future! When will you be able to match us with this thing? ”

"Huh! Another rush! Zhang Zhimu said, "This matter can be regarded as a successful experiment today." Organize production immediately, you can rest assured, it will be easy to use and notify you immediately. But when they try to take pictures of welds, they need your cooperation! ”

"That's fine, feel free to come to me!" Lu Wenchen is not bragging, all the welders in the kiln are his apprentices. Now, every year, Lu Wenchen's technical school can train a large number of welders and automobile driving and repair technicians. Lu Wenchen not only cultivates people, but also establishes a welding technology research center to continuously study new welding technologies. Of course, I am very interested in this X-ray inspection technology.

Everyone talked about the X-ray again, and they all got up to leave.

Qingfengzi said to Zhang Zhimu: "Mr. Zhang, there is news that you can be interested in. ”

"Oh! Master Qingfengzi hasn't given us good news for a long time! Zhang Zhimu joked.

"Huh! Our color photo problem may be solved! Qingfengzi smiled and said, "I haven't solved the problem of blue negatives before. Now, by splitting light, we can make negatives of red, green, and blue, and then synthesize them. This shows all the colors. ”

"Oops! You've been busy with this for a few years, haven't you? Zhang Zhimu said happily, "It's best that our color movies can come out early." ”

"Yes! Our group got this stuff without doing anything else, and now we finally have an eyebrow! Qingfengzi said, "And the adhesive fiber has also been pulled out of the silk." Li Yunhe is about to arrange production! ”

"Good! The good news keeps coming! Zhang Zhimu knew that Qingfengzi had not moved, that is, he had been researching new things. If there is movement, it is a major breakthrough.

When Lu Wenchen left, he was still reminding Zhang Zhimu, "Mr. Zhang! The safety of our welded boilers is very important, whether it is a power plant or a marine steam turbine boiler. Therefore, we dare not weld the boiler with a higher pressure. In some high-pressure sections, we had to take a lot of cumbersome remedies for safety. It would be much safer to have this x-ray. Our boilers can be increased by increasing the pressure. ”

"Good! Don't worry, I'll keep an eye on them, and I'll be the first to let you use their X-ray machine as soon as it comes out. Zhang Zhimu comforted Lu Wenchen, "By the way, you will expand enrollment next year, how are you prepared?" ”

"You can rest assured, the teachers of the basic courses are all graduates of our university, and the welder and mechanic courses are all taught by the top technical students selected by me!" Lu Wenchen is no longer the polite little boy he was when he first came to Yaogang. Now he is the principal of a school with thousands of people, and he is an authority on kiln welding technology.

Seeing everyone off, Zhang Zhimu and Yang Chang came to his office together.

Yang Chang introduced: "I know you want to ask us about the field effect management. The last time you told us the basics, we started experimenting with it. In fact, the process technology is nothing, but the method is different. A few days ago, they made some, but the yield was too low and it was easily damaged. Often, it is just checked and it is good, and it will be broken after a while. At present, it is not practical, but the technical threshold is not too high. ”

"FETs are useful, try to break through!" Zhang Zhimu said, "I want to know, what's going on with the computer?" ”

"We're experimenting with connecting to a monitor. It would be much easier to use a monitor. Yang Chang said, "I think that time can be used to reach the level of practicality." ”

"How's their advanced language going?"

"I've heard that they're just starting to do assembly language. It's still early for high-level languages! Yang Chang said, "This thing is in a hurry!" ”

"Yes! I'm in a bit of a hurry. Zhang Zhimu said, "Do you know why I'm in a hurry to let Li Di get a stepper motor?" ”

"Mr. Zhang, I think step electrolysis is very useful! In the future, the action of our switches can also be commanded by stepper motors. Yang Chang replied.

"I'm trying to get a disk drive for a computer!" Zhang Zhimu said, "You know that our information can be recorded on tape. However, the tapes are entangled, and a little data can be read from the tape first, and the tape must be exported before it can be read. Very poor timeliness. But have you ever wondered if it would be easy for us to read any piece of music in the way we use a turntable? Just know where the piece is on the turntable. ”

"But there's no way to record information on the record?" Yang Chang didn't understand what Zhang Zhimu meant.

"Yes, but what if we coated the surface of the record with magnetic powder and then used the magnetic head to record the information in circles?" Zhang Zhimu reminded Yang Chang.

"Oh!" Yang Chang nodded and said, "It's kind of interesting!" Tell me how to get it? ”

"We rotate the disk steadily, and use a small stepper motor to control the head to move step by step along the radial direction, is it possible to record the information in a circle, or read it out in a circle?" Zhang Zhimu continued to explain to Yang Chang.

"Yes, yes, you go on!" Yang Chang somewhat understood.

"We can record some of our fixed information and the directory of information we record in a fixed area of the disk, indicating where the information is recorded on the disk." Zhang Zhimu said, "In order to be more precise, we can further divide the disk into several sectors and several families. In this way, the program we write can be recorded on such a disk, and read it into the computer when it is used and when it is used. ”

"That's right!" Yang Chang said, "Mr. Zhang, this disk drive should be developed as soon as possible." I'll have time to go to Li Di again to see how their stepper motors are doing. However, I'm going to look at the disk drive with the people who do the computer first, and then come up with what kind of stepper motor I need. ”

"Good! Hurry up on this. Zhang Zhimu said, "Yang Chang, have you thought about it, in the future, if we record all our account information on the disk, we can read it from the disk when we want to use the computer to query a certain personal information." Then it is displayed on the display. ”

"Can a disk record so much information?" Yang Chang asked.

"If one doesn't work, we'll just use N!" Zhang Zhimu said.

"Hey! Yes! Yang Chang said, "I understand that not only population information can be recorded on disk, but all information in the future can be recorded on disk." You can use a computer to quickly query. Oh, my God! I said, Mr. Zhang, why do you attach so much importance to computers? The future usefulness of this computer is simply too great! ”

"yes!" Zhang Zhimu said, "Our computers will be faster and faster in the future, and they will be able to do more and more things." The capacity of the disk records you are engaged in will also increase. Let me tell you, every house will have a computer in the future. Every information we can think of in society is stored on large disks. We can use a computer to look up the information we need through a phone line. There's a lot to do! Zhang Zhimu said that he was a little excited, and remembered the convenience of using computers in his previous life.

"Mr. Zhang, in this world, only I can understand a little bit of what you say. But I can't imagine what you said it would have been like. But I know that computers will be more and more useful. Yang Chang said very sincerely.

"Good! Things have to be done slowly, you're right, some things are in a hurry. As long as you keep working hard, everything will fall into place! Zhang Zhimu said.

Zhang Zhimu and Yang Chang were dreaming about the bright future of computer applications when suddenly the phone rang. Yang Chang picked up the phone, listened for a while, and then handed the phone microphone to Zhang Zhimu, saying, "Baotou, General Zhou Yuji's phone!" ”
