Chapter 567: Win-win-win! They gained spiritual and cultural life
The reason why things like Nixie tubes are made with overlapping digits is not because it is impossible to make a segmented structure like an 8-segment LED digital tube, but because Nixie tubes were popular in the era when analog circuits were prevalent, and it is far less convenient for analog circuits to process 8-segment displayed digits than to directly select the overall digit.

"This digital display component is quite interesting. To display a number, the pin signals that need to be controlled are more than those of a Nixie tube, but the total number of pins is less than that of a Nixie tube."

A Nixie tube with a decimal point requires at least 12 pins, including the numbers 0 to 9, the decimal point, and a common terminal.

The 8-segment LED digital tube has 9 pins, 8 for segment selection and one for common terminal. As for whether the common terminal is positive or negative, both are available, but the common cathode type is more common. This is the same as when the microcontroller pin is used to directly drive the LED lamp, most of them use current injection drive, which reduces the driving capability requirements for the pin.

Another advantage of current injection driving is that it can ensure that these lights will not light up randomly when the microcontroller is just started, and have to wait for the program to control it. Because these IO pins of early microcontrollers are mostly in high-impedance state or state "1" when they are powered on, they will not light up in this state if driven by current injection.

For the technical staff in the department, this thing is too new and some of its benefits cannot be appreciated immediately.

However, the four obvious advantages of LED diodes have aroused the chief engineer's great interest.

It is strong and can be used in harsh environments. It is not afraid of vibration, impact and the like, and its maintenance performance will be greatly improved.

Being light and small means that the device occupies a small area and volume, which makes it very useful in many small and micro devices.

Low power consumption. First, many devices are powered by batteries. At this time, battery-powered devices can save every penny they can. There is also a related benefit - the driving circuit requirements are lower, and the cost, size, maintenance and other performance of the driving circuit will increase accordingly.

As for high reliability, at first glance it seems to be related to sturdiness, but in fact it is at most somewhat related. Reliability has actually always been an old problem that has plagued our equipment and machines.

In his previous life, Gao Zhendong traveled long distances with the older generation and found that they always brought enough food and water, even if the journey was only a few hundred kilometers. Gao Zhendong was very puzzled and asked them how many times they had come. The answer was that the older generation had too many experiences of being left cold and hungry halfway due to the long-distance transportation tools of the 20th century.

So just these four points made the chief engineer of the department surprised and happy. Don't underestimate the indicator light. Gao Zhendong knew that there was a flight crash and all the people on board were killed. The cause was that a crew member was concentrating on repairing a light bulb, and the only broken thing on the crashed plane was this light bulb.

He said to Gao Zhendong, "Wait a minute, I'll call the leader over. He happens to be in the department today."

Gao Zhendong could go to him directly, but he knew exactly when to invite the leaders of the 12th Ministry of Machine Building over.

Gao Zhendong was confused when he heard this. Should he alert the leaders of the 12th Ministry of Machine Building?

Chief Engineer: It's so new. What do you take every time you come? Don't you have any idea? Do you think I want to alarm him? It's all your fault.

As the chief engineer of the ministry expected, the leader of the 12th Ministry of Machine Building received the call and knew that Gao Zhendong had brought new things and asked him to come over, so he came over happily immediately.

Before anyone even entered the door, the laughter could already be heard.

"Hahaha, Zhendong, what good news have you brought me?" As time went by, he called "Xiao Gao" less and less. Generally, he was called "Chief Engineer Gao". Those at the ministerial level mostly called him "Comrade Zhendong" in formal occasions and "Zhendong" in private.

Speaking of this matter, Sha Zhu and the leaders of the ministry enjoyed the same treatment.

Before Gao Zhendong could say anything, the chief engineer of the department came up to him and explained the matter about LED diodes and 8-segment digital tubes.

The chief engineer's eyes lit up. Although he knew that Gao Zhendong had "obtained" this thing, the fact that he took it out showed that he was absolutely sure of the channel through which he obtained it.

"Good, this thing is good. Although it is not decisive, it is a very useful auxiliary component." The leader of the 12th Ministry of Machine Building praised it while looking at the test results.

Looking at the light emitted by the round LED beads, everyone was dazzled. It was really beautiful.

After expressing his feelings, the leader turned around and asked: "Where did this thing come from? Is the channel reliable?"

Although I know the answer, I still want to confirm it.

Gao Zhendong nodded and told the whole story: "I actually took out the principle of this thing and gave it to my eldest brother-in-law's company in Hong Kong Island to implement it. The intellectual property protection has been completed. Although this thing is very useful, it is essentially very ordinary and does not involve anything sensitive. I simply gave it to him and let him be responsible for the implementation outside and use the chicken to lay eggs."

The leaders at the level of the 59th Ministry of Machine Building were not unaware of the matter of revitalizing Electric Industry. After all, this pair of white gloves made great efforts in the early stage of DJS-60 and , and they are still playing a very important role in some other matters, for example, bringing a large amount of technical information and books from outside into the country.

Therefore, Gao Zhendong had nothing to hide. If he did, it would cause problems.

"Hahaha, well, that's a good idea. Our domestic energy and technical strength are limited. We need to focus on solving important issues such as computers, integrated circuits, and communication technologies. It's just right to let our own people out there work on the light-emitting diodes!"

In many cases, you don’t have to think too much when dealing with people of higher rank. “Our own people”, the leaders of the 12th Ministry of Machinery Industry had a very clear idea of ​​the positioning of Zhenxing Electric.

"Actually, there is another reason. Based on my analysis of foreign technical data, they should be close to success in researching this thing. Zhenxing Electric's move is actually cutting them off. Hahaha." Gao Zhendong added another purpose of his.

"Ah? Hahaha! Well done!" The leader was very happy about Gao Zhendong's approach, which did not suffer any loss and even cheated foreigners. You have been cheating us for more than a hundred years, and this is where you end up.

After saying that, the leader quickly made arrangements: "Okay, I'll arrange for someone to contact Zhenxing Electric and buy from them right away." Since the technology is in the hands of Zhenxing Electric, there is nothing to worry about. It is reassuring to buy from their own people.

Gao Zhendong shook his head: "No need."

"No need?" The leader of the 12th Ministry of Machine Building was a little surprised.

Gao Zhendong smiled and said, "Although Zhenxing Electric has completed patent protection, its own production is not enough to meet the needs of the whole world, so they select authorized manufacturers worldwide, and they provide technology and collect licensing fees. The manufacturers produce and buy their own products. I want them to keep all the authorizations of the Economic Assistance Council."

The leader thought about what Gao Zhendong said and understood.

"You mean... we produce and sell it ourselves?"

Gao Zhendong nodded: "Yes, that's what I mean."

The leader was very happy: "Great, that's great! It's just that the old guy from the Foreign Trade Department got a bargain again."

Leader of the Ministry of Foreign Trade: A-choo! Who is talking about me again?
Gao Zhendong's words were very clear, and the 12th Ministry of Machine Building could naturally understand what he meant. Since the national authorization of the Economic Assistance Association was retained, it would be natural for this part of the market to be retained as well.

To be honest, no one can make a difference in this market if we replace them with the Oceanic Convention countries. Maybe due to historical origins and legacy issues, sales can penetrate into some countries, but they cannot conquer all countries.

But we are different. We have secured our share of this market.

In this way, in addition to completing the domestic supply at low cost and without restrictions, we can also make some money. Judging from the import situation of agricultural and sideline products last year and the support and improvement for the domestic market, foreign exchange is a treasure.

After talking to the leader of the 12th Ministry of Machine Building, Gao Zhendong turned around and went back to the Third Rolling Mill. There was still a lot of things to do. Someone would definitely come to see him in the afternoon because he had called last night.

However, in the afternoon, before the person he had an appointment with called him, someone else called him.

I picked up the phone and it turned out to be the leader of the Ministry of Foreign Trade.

"Zhendong, thank you so much. You have found a new way for us." The leader of the Foreign Investment Department started by expressing his gratitude and said that the "Advanced Individual in Foreign Investment Work" award was worth it.

Although this thing apparently belongs to Zhenxing Electric, everyone knows that Gao Zhendong played a big role in it. At least he can influence the sales strategy of Zhenxing Electric.

Gao Zhendong quickly spoke modestly, as if he had only done something insignificant.

After some jokes, the leader of the Ministry of Foreign Trade asked Gao Zhendong for help.

"Zhendong, I heard that the tape recorders that sell very well in the Oceania Convention countries are also products of Zhenxing Electric, right?" Although the tape recorders used in China are purchased from Zhenxing Electric, cassette tape recorders cannot be produced in China. There are very few tape recorders produced in China, and they are all very large.

It can be used as a record player, but it is inconvenient to use it as a portable device, whether in terms of portability, ease of use, or environmental adaptability. Especially the tape, which is extremely troublesome compared to cassette tapes.

As for the economic assistance countries, haha, they are the same as us.

As soon as Gao Zhendong heard this, he knew what the leaders of the Ministry of Foreign Trade were thinking. Regarding the imitation of LED, Zhenxing Electronics also authorized us to produce tape drives and magnetic tapes. On the one hand, it was to meet domestic demand, and on the other hand, we could sell them to other countries that assisted the association.

In Gao Zhendong's opinion, this is a good thing. If Zhenxing Electric wants to expand its business to economic aid countries, it will have no chance in the short term. However, with our Ministry of Foreign Trade taking the lead, things are different.

Zhenxing Electric sells its products to the OPEC countries, and we sell to the Economic Aid Association countries, thus completing the loop.

This is a win-win situation for all! In addition to our own people, people in the countries of the Economic Support Association have gained a spiritual and cultural life that is easy to carry with you!
