Li Jian was forced by Yuan Kaichun to eat and then fell asleep, and after saying that he had gone through school, he played up the scene where he used his test results to shock off his glasses, which made Yuan Kaichun forgive him for his so-called leave.

The price is that it is stipulated that after waking up in the afternoon, you can't go to the tape recorder factory, and you have to have dinner with her at home, which can be regarded as a celebration of Yuan Kaichun's return from work.

When Li Jian came to the Chenguang Tape Recorder Factory again, it was already the next morning, and standing in front of Li Jian was Liao Weihong, whose eyes were red and his spirit was very excited.

"It's finished?"

"It's done, you try."

Liao Weihong had been waiting at the gate of the factory for a long time, and after seeing Li Jian, he couldn't help but say that he stuffed a black brick into Li Jian's hand, and he rushed into the workshop, not like a middle-aged person at all, but like a child who had just skipped from school.

"Jingle Bell ......"

The familiar telephone ringing rang from Li Jian's hand, Li Jian was excited, he was reborn for a month, and he dreamed all the time that he would change the world, change the country's science and technology, and even change the pace of scientific and technological progress in the whole world.

He thought that the library in his mind existed, and there was no shortage of all kinds of knowledge, and in this world, it was not a little bit of gold that could change the world with a casual shot, but when it came to real operation, he knew how difficult it was.

At this moment, listening to the ringing of the phone in his hand, his first thought is to his own country, those pioneers who have contributed their own strength to the development of national science and technology, if it were not for their struggle in poverty and whiteness, where would the country come from to catch up step by step, although there is still a distance from some top technology, but it is no longer out of reach, at least there is hope to catch up.

"Answer the phone."

Liao Weihong ran out of the workshop and yelled at Li Jian excitedly.

Li Jian hurriedly pressed the call button on the black brick, and I have to say that the microphone that Liao Weihong temporarily processed is really ugly, bigger and heavier and ugly than that kind of big black walkie-talkie, but Li Jian can't wait to kiss it.

Liao Weihong is a talent, Li Jian just told Liao Weihong his thoughts, he relied on his own sense of electronic components, and forced this cordless phone out, of course, the circuit diagram was drawn by Li Jianlai, but even so, Liao Weihong is equivalent to creating from scratch.

At least this prototype made Li Jian very satisfied, although there was a slight current sound in the microphone when talking, but the distance between the two, I am afraid it was already fifteen meters, and there were three brick walls in between, which showed that the single-channel scheme adopted by Liao Weihong was suitable.

The call between the child and the mother machine has been completely resolved, and it depends on the external call.

"Director Liao, Director Liao, connect the phone to the external line, you can make a call and try."

Li Jian waited until Liao Weihong responded and hung up the phone, and saw that Liao Weihong had rushed out carrying the wooden box over there, and rushed into the factory director's office.

"I'll fight."

poked his head out and shouted at Li Jian, Liao Weihong immediately shrank in again, Li Jian smiled, these people who are engaged in technology are the same as themselves, and if they have new things, they must be understood immediately.

"I can fight, I can fight."

Liao Weihong ran out of the factory director's room half a minute later, standing beside Li Jian, just like a primary school student seeing a teacher, with an excited look on his face, but there seemed to be a little regret in his satisfaction.

"It would be nice if the microphone could also make a call, isn't it just to add a set of dial-up circuits on it, by the way, you have specially reserved an opening on the microphone and the phone, and there are two data transmission lines, what are you going to do with it?"

"Confidential, I see that the volume of the prototype is a little smaller than the original, it was originally larger than a basketball, and now it is half the size of a football, Director Liao, have you changed the spatial structure?"

Li Jian and Liao Weihong sold a pass, Liao Weihong is a good hand in technology, but he has not experienced the wave of domestic copycats in later generations, he can't understand many things, even if there are patent restrictions, it still can't stop batches of high imitations from appearing on the market.

In this case, the only way is to make the counterfeits unable to keep up with their own rhythm, then they must keep maintaining the generation gap in science and technology, in order to use their leading edge to occupy the market and earn development profits.

The two external ports reserved on the telephone are Li Jian's killer features.

Liao Weihong didn't know what Li Jian was thinking, and when he heard Li Jian talk about the smaller size of the prototype, he suddenly puffed up his chest,

"Our old Liao didn't work in vain one night, I separated the A16 from the SXS323, replaced it with a vertical board, and saved a little space, and some changes were made in other places, and the space was streamlined, and it was made up like this, that is, when the time came to go to the workshop, I am afraid that there was no way to make it so small, the level of the workers was uneven, I was afraid that it would be scrapped, and we could enter a total of 1,000 sets of launchers."

"Niu, this batch of goods is sold, Director Liao's first achievement, let's debug and debug, and then prepare to pour the mold, finalize, our Chenguang Factory, also changed back to the handicraft workshop, Director Liao has to let your apprentices study hard and work hard, this is our guy."

Touching the prototype and feeling the wood fiber that Liao Weihong had not had time to trim on it, Li Jian was full of confidence.

A month's time, in Li Jian's opinion, it seems to be like an afternoon's time, the chirping eyes passed, during which Liao Weihong ate and lived in the factory all day, causing his wife to come to the factory with the child to look for seven or eight times, until finally Liao Weihong did not go home, just threw a thousand yuan back, and his wife left with a straight face and secretly smiled.

Duan Tongshan has never returned to Chunjiang since he opened the factory meeting, and the patent law that has just been implemented in 85 years is the same as the book of heaven for most ordinary people, especially in this era, what is intellectual property and how much is a catty? Or what most ordinary people think.

Fortunately, Duan Tongshan was originally a demobilized cadre, and he could be regarded as a half-land snake in Chunjiang and Jiangcheng, running back and forth, and finally it took more than half a month to complete the procedures, and hundreds of official seals were stamped before and after, and finally the patent for cordless phones was established.

After that, he did not return to Chunjiang, but was assigned a new task by Li Jian, in his own words, this Bai lived for more than forty years, let a teenage child run around, but he was still willing to listen to Li Jian.

As for Li Hongjun, he had already discussed the matter with the printing house, and he was busy sending paper to the printing house every day, and at this time he understood what Li Jian meant by letting him exchange ten sheets of paper for one paper, although in the end he used five sheets for one.
