At this time, it's time to say good things, what are you doing earlier? Yu Zixian glanced at him.

"Director Luo, I only give myself three months, no matter what I do, I have to leave! And you also promised me two conditions!" Yu Zixian said casually angrily.

The old man first asked, "What conditions?"

Looking at the old man's appearance, he knows that the old man still hopes that he will stay.

"The first condition: for three months, the factory can no longer refuse me to leave!"

Staying in a state-owned enterprise and trying to do something is too much involved, and no matter what you do, you will be constrained! Therefore, Yu Zixian had already made up his mind before this that he would not stay in the factory anymore and must have his own things to do.

However, before leaving, it is also the wish of the old man to help the Sifang Electron Tube Factory in the end, and he will not leave any regrets, as a military worker's regrets!

Yu Zixian saw that Luo Shouwu had no objection, so he continued to say that the choice was in his own hands anyway.

"The second condition is that these three months do not limit my freedom to take leave, specifically that I can take time off at any time!

"The third condition, when I leave, give me some people...... "To develop, you can't do it alone." But at this time, college students, whether they have graduated or are about to graduate, will not be his turn.

"No problem, I can promise you now. Luo Shouwu's answer was neat.

What Yu Zixian didn't expect was that Luo Shouwu agreed to all the conditions neatly this time!? Could it be that Comrade Lao Luo really wants to make trouble?

In fact, Luo Shouwu also has his own considerations. For the future of the Sifang Factory, Luo Shouwu, who is about to retire, has made up his mind that this time he must take the opportunity of the inspection to find a cooperation project that meets the development quota of the Sifang Electron Tube Factory. As the proposer of the original proposal, Yu Zixian has a clear plan, and when the factory is on the right track, his mission will be completed...... Besides, as long as he gives him what he wants to do and let him see hope, he will naturally not leave when the time comes.

And Yu Changfu already had a glimmer of hope in his heart when he heard that his son was going to put forward conditions before, and now when he heard Luo Shouwu's answer, he didn't drag his feet, and a trace of expectation suddenly rose in his heart - the expectation for the rise of Sifang Electron Tube Factory!

But Yu Zixian was a little dumbfounded, what should I do now?

"Wait, I still have three conditions......"

"Stinky boy, you have to make an inch, don't you......" said the old man, fumbling for something handy.

Yu Zixian saw that it was wrong, and ran away as soon as he slipped away. If he doesn't run again, he will have to be subjected to "air raids......

There was a laughing and scolding of the old man "Little Rabbit Cub" from behind......

Yu Zixian, who ran away, reacted at this time, didn't he want to leave, but he promised to stay for three months: "Damn, the two old men will join forces to set themselves up!"

But he could go back and say, "Excuse me, I just farted what I said?"

However, since this is the case, let's give it a try and make good use of the huge platform of the Sifang Electron Tube Factory! Maybe it can really give Sifang Electronics a different tomorrow.

At the same time, you can also grasp some precious resources...... Connections, money, talent, these are all good.

After all, there are only three months, and you can still dig into the corners of the wall when you leave. Besides, we reborn people are also dignified, what we have said, and what we have let go...... Bah......

Actually, Yu Zixian hasn't said one thing yet, that is, this delegation to Japan is really rare, and he really wants to take a look. Especially with this kind of inspection group organized by the national level, you can see things that ordinary private inspection groups can't see! This is too precious for Yu Zixian, who still has nothing!

At this time, there are a lot of good things, it's a pity not to take a look!

Besides, the first two conditions mentioned by myself provide the greatest possible convenience for doing what I want to do. It doesn't affect much.

When passing by the living room, Yu Zixian remembered Hao Meng again, and quickly made a phone call, and then returned to his room.

Sitting at the desk, Yu Zixian solemnly opened a file bag taken out of a drawer.

In the file bag is a remote control circuit design scheme, and now this text can be directly used to apply for a patent as long as it is slightly converted according to the patent application documents.

"It takes at least two weeks, in case it's not enough...... It might take three weeks, but now it's all going to be postponed, at least until we get back from the book. Yu Zixian couldn't help sighing.

"But it seems that it can be handed over to Liu Jian and Hao Meng to apply for a patent!?"

"Yes, that's it, one understands technology, and the other has connections!"

The reason why Yu Zixian wants to take out the remote control circuit design scheme to register a patent is because compared with the current products on the market, this circuit board has fewer remote control system chips, but the performance is better and the control is more convenient. The key is to realize the substitutability of some models of chips and increase the reliability of chip supply.

This was optimized by him with some common circuit designs in later generations. This design scheme is another achievement of Yu Zixian in the past year and a half, in addition to the TA two-piece movement. Originally, it was planned to hand over the patent application to Liu Jian and them. Now that he is not leaving for the time being, it is a good choice for Yu Zixian to use it to open up the situation for himself.

He also has a lot of board designs that are more performant and technologically advanced, but now is not the time to take them out. Advanced boards require more advanced microprocessor-level monolithic movement control. Now that it's taken out, I can't produce it myself. It is better to apply for a patent and leave it to others, than to wait for the right opportunity to do it yourself.

Last year, the CAD8801 movement 47 cm (19 inches) organized and developed by the Ministry of Machinery and Electronics Industry has been put into production, and there are many products produced by major TV factories, such as: Yanjing brand 8312 type, Great Wall brand JTC473 type, and the famous Panda brand 3610 type.

CAD8801 movement is a collection of technical backbones and experts from some large manufacturers to jointly develop the movement, coupled with the use of advanced new generation CAD technology, reasonable design, advanced technology. However, due to the supply of remote control chips and the cost, the movement only has an interface for remote control and AV function expansion.

However, they underestimated the popularity of remote control TVs, and when the CAD8801 movement was produced in a large area and the remote control function began to gradually become popular, the TM50536 remote control chips that matched it would be in short supply and the price would rise sharply.

Because the supply of TM50536 remote control chips has always been in the hands of Toshiba manufacturers, and in order to increase the shipment and profit of the whole movement, the remote control module is basically not only sold, but the price will be very high if you want, and it is a limited supply.

This situation will appear soon,Because under the pressure of the big price reduction of domestic color TVs,In order to increase the sales of their own brand color TVs,To achieve the purpose of differentiated competition,Their color TVs have begun to be widely equipped with remote control functions。 Domestic manufacturers are also rapidly expanding remote control function modules.

Yu Zixian has paid special attention to it before,More domestic TVs sold on the market still use the knob switch of the TV body to control the selection、Volume adjustment and other functions,The new models currently sold have begun to appear color TVs with remote control configuration。

In fact, today's remote control technology has been developed mainly using semiconductor devices that transmit and receive infrared rays. In Yu Zixian's view, optimizing a remote control circuit is much simpler than optimizing the movement circuit, and the key is that the manufacturing cost is also low. If the optimized remote control circuit can be manufactured, when the remote control circuit on the market is out of stock in a large area, it will be time for Yu Zixian's remote control optimization circuit board to come on the field.

Yu Zixian was waiting for this opportunity.

Now, he has several circuit designs in his mind, thanks to the electronics design course in his junior year. At that time, they were assigned a project design of "installing a remote control device on an old-fashioned color television". This kind of topic involves both hardware design and software programming, which is indeed difficult for Yu Zixian, who is at the half-level level at that time.

The deepest impression is the query of some information,Like Hitachi CPT2018 color TV,It belongs to the products developed before the 90s,And more than 20 years later,If you want to query the internal function code of his existence movement ROM,Naturally, it is not easy to find,It can be regarded as taking Yu Zixian a lot of effort。

Although it was difficult, they were impressed by the fact that they finally designed it with the help of a large number of materials and teachers. At this point, there are two design options that can be drawn in your mind.

It's just that some places have been a little blurred for many years, and the circuit design has to be redetermined, but fortunately, the design framework of remote control circuits like this is basically the same, with the supporting application-specific integrated circuit as the core, and then the auxiliary circuit can be designed.

Just like the TM50536 remote control chip circuit that is about to be in short supply now,4Bit TV-specific TM50536-560SP microprocessor is responsible for voltage synthesis and high configuration tuning system,M58655P (memory)、M5046AP (remote control transmitter)、CX2016A (remote control receiver) and other integrated circuits cooperate to form a full remote control system of color TV。

Originally, Yu Zixian's resignation was planned to go to Xiangjiang to try to apply for a design patent for a remote control circuit board, and by the way, find several chip supply channels involved in TM50536 remote control circuit.

According to the plan, if the patent is successfully registered within half a year, Yu Zixian, who has already left the company, will consider selling him, and it is best to find an appraisal agency to make an appraisal and sell it to the factory at a discount, which can also give Yu Zixian a small return to the factory while earning the first pot of gold.

This kind of cost-effective, powerful remote control circuit board can be used as the fist product of Sifang Electron Tube Factory, if the factory does well, it is very promising to achieve transformation!

A spark can start a prairie fire. This remote control circuit board is the "spark" planned by Yu Zixian.

But now I can leave this matter to Liu Jian and Hao Meng.

Now, what Yu Zixian should be thinking about is going to do something.
