Chapter 567 Three wins! They have gained a spiritual and cultural life
The reason why things like Nixie tubes are made into numbers that overlap each other is not because it cannot be made into a segmented structure like an 8-segment LED digital tube, but because of the Nixie tube. Light tubes were popular in an era when analog circuits were popular. Analog circuits wanted to process 8-segment display numbers, but it was far less convenient than directly selecting the overall number.
“This digital display component is a bit interesting. If you want to display a number, you need to control more pin signals than 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, numbers 0~9, a decimal point, and a common terminal.
There are 9 8-segment LED digital tubes, 8 segment selections, and a common terminal. As for whether the common terminal is positive or negative, both are available, but the common cathode is dominant. This is different from using a single-chip microcomputer. When the pin directly drives the LED lamp, it is the same reason that most of the LED lights are driven by sinking current, which reduces the driving capability requirements of the pin.
Another advantage of sinking current drive is that it can ensure that when the microcontroller is just started, these lights will not light up blindly, but have to wait for the program to control it, because most of the IO pins of early microcontrollers are in a high impedance state when they are powered on. Or state "1", if they are driven by current sink, they will not light up in this state.
For the technical staff in the ministry, this thing is too new, and some of its benefits cannot be realized immediately.
However, the four advantages that have been seen in LED diodes have made the chief engineer very interested.
It is strong and can be used in harsh environments. It is not afraid of vibrations, shocks, etc., and the maintenance performance will increase sharply.
Lightweight and small means that the device occupies a small area and volume, and is very useful in many small and micro devices.
The power consumption is low. First, many devices are powered by batteries. At this time, battery-powered devices can naturally save every penny, and there is a related benefit - the driving circuit requirements are lower, and the cost and cost of the driving circuit are reduced. Performance such as volume and maintenance 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 but not much. Reliability has actually been an old problem that has plagued our equipment and machines.
In his previous life, Gao Zhendong ran long distances with the older generation, and he would find that they always brought enough water, even if it was only a few hundred kilometers away. Gao Zhendong was very puzzled and even asked specifically I asked several times, and the answer is that the older generation has too many experiences of being caught halfway by the long-distance transportation of the 20th century, freezing and hungry.
So these four points surprised and delighted the chief engineer of the department. 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 one crew or not. Together they concentrated on repairing the light bulb, and the only thing that was broken 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 ministry today."
Gao Zhendong can go to him directly, but he knows when to invite the leaders of the 12th Machinery Department.
Gao Zhendong was confused when he heard this. Or was he going to alert the leaders of the 12th Machinery Department?
Chief Engineer: It’s so new. What do you get every time you come here? You don’t know what to expect? Do you think I want to alarm him? You forced me to do this.
As expected by the chief engineer of the department, the leader of the 12th Machinery Department who received the call knew that Gao Zhendong had brought something new and asked him to come over, and he immediately came over happily.
Laughter has already passed through the door before anyone entered.
"Hahaha, Zhendong, what good news have you brought me again?" As time goes by, the number of people called "Xiao Gao" has become less and less, and the more common ones are called "Chief Engineer Gao". Most of them are "Comrade Zhendong" in formal situations and "Zhendong" in private.
In this matter, Shazhu and the ministry leaders enjoy the same treatment.
Before Gao Zhendong could say anything, the chief engineer of the department had already come up to him and told him about the LED diodes and 8-segment digital tubes.
The eyes of the chief engineer were shining. Although he knew that Gao Zhendong "made" this thing, since he took it out, it meant that he was absolutely sure of the channel through which he got it.
"Okay, this thing is good. Although it is not decisive, it is a very useful auxiliary component." The leader of the 12th Machinery Department was full of praise while looking at the test results.
Looking at the light emitted by the round LED lamp beads, everyone was a little dazzled. It was really beautiful.
After sighing, the leader turned his head: "Where did this thing come from? Is the channel reliable?"
Although he knew the answer, he still wanted to confirm it.
Gao Zhendong nodded and told the truth: "I came up with the principle of this thing and handed it over to my uncle's company in Hong Kong Island to implement it. The intellectual property protection has been completed. Although this thing is of great use , but it’s quite ordinary in nature, and it doesn’t involve anything sensitive. Just leave it to him and let him be responsible for landing outside and borrowing chickens to lay eggs.”
The matter of revitalizing the electric industry has reached the 12th machine. It’s not like the leaders at the ministry level don’t know this. After all, at the beginning of DJS-59 and 60, these white gloves were very helpful. Now, they are also playing a very important role in other things, such as bringing outside A large amount of technical information and books were dumped into the country.
So Gao Zhendong has nothing to hide, but hiding it will cause problems.
"Hahaha, well, this is a good idea. Our domestic energy and technical strength are limited. We must focus on solving important issues such as computers, integrated circuits, and communication technologies. You, the light-emitting diodes, are left to the outside world. It’s just right for my own family to do it!”
There are many things that you don’t have to think about too much when dealing with high-ranking people. "One's own family", the leaders of the 12th Machinery Department are very clear about the positioning of revitalizing the electric industry.
“In fact, there is another reason. According to my analysis of foreign technical data, their research on this thing should be close to success. The revitalization of electric power industry actually intercepted their efforts. Hu, hahaha." Gao Zhendong added another purpose.
"Ah? Hahahahaha! Well done!" The leader was very happy for Gao Zhendong's method of cheating foreigners without suffering any loss at all. You have cheated us for more than a hundred years, where are you now? .
After saying that, the leader quickly made arrangements: "Okay, I will immediately arrange for people to contact Zhenxing Electric and buy from them." The technology is in Zhenxing Electric's hands, so there is nothing to worry about. , buy it from your own people, be sure of it.
Gao Zhendong shook his head: "No need."
"No need?" The leader of the 12th Machinery Department 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 world's requirements, so they choose authorized manufacturers around the world to provide technology. They charge a licensing fee and the manufacturers produce and buy it themselves. I want them to retain the entire national scope 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 could now Happy: "Okay, great! It's just that the old boy from the Foreign Trade Department is cheaper again."
Leader of the Foreign Trade Department: Ah sneeze! Who is talking about me again?
Gao Zhendong's words have been made very clear. The 12th Ministry of Machinery can naturally understand what he means. The national authorization of the Economic Assistance Association has been retained, which naturally also retains this part of the market.
To be honest, this part of the market would not be successful for anyone in the Ocean Convention countries. Perhaps because of historical origins and legacy issues, sales can penetrate into some countries, but they cannot succeed in all countries. .
But we are different. This market is guaranteed.
In this way, in addition to completing the domestic supply at low cost and without restrictions, you can also make some small money. Judging from last year’s import situation of agricultural and by-products and the intensity of domestic support and improvement Look, foreign exchange is a treasure.
After explaining the matter to the leader of the 12th Machinery Department, Gao Zhendong turned around and returned to the third rolling mill. There were still many things to do. Someone must come to see him in the afternoon, because he called last night.
However, before he could wait for the person he called to make an appointment in the afternoon, someone else's call came to him.
I picked it up and heard it, the leader of the Ministry of Foreign Commerce.
"Zhendong, thank you so much. You have found a new way for us." The leader of the Ministry of Foreign Trade thanked him and said that the leather bag of the "advanced individual in foreign business work" was worth it. .
Although this thing is apparently for Zhenxing Electric, everyone knows that Gao Zhendong played a big role in it. At least he can influence Zhenxing Electric's sales strategy.
Gao Zhendong quickly humbled himself, as if he had just done something trivial.
After a few jokes, the leader of the Ministry of Foreign Commerce asked Gao Zhendong for help.
"Zhendong, I heard that the recorders sold well in Ocean Convention countries are also products of Zhenxing Electric, right?" Although the recorders used in China are bought from Zhenxing Electric, they are However, cassette tape drives cannot be produced in China. There are very few tape drives produced in China, and they are all very large ones.
It is okay to use a record player, but it is inconvenient to use it as a portable device, whether it is portability, ease of use, or environmental adaptability, especially the tape. Compared with the cassette tape, it is not a general trouble.
As for the Economic Assistance Council countries, haha, they are just like us.
As soon as Gao Zhendong heard this, he knew what the leaders of the Ministry of Foreign Commerce were thinking. Regarding the imitation of LED, we were also authorized by Zhenxing Electric to produce tape machines and tapes. Firstly, to meet domestic needs, and secondly, to expand business Help the country sell it.
In Gao Zhendong's view, this is a good thing. Zhenxing Electric wants to do business in Economic Assistance Council countries and should not even think about it in the short term. But with our Ministry of Foreign Commerce taking the lead, things will be different.
Zhenxing Electric sells itself to the Ocean Convention countries, and we sell to the Economic Assistance Council countries. The loop is closed.
It’s a win-win-win! In addition to our own people, people in the Economic Aid Society countries have gained a spiritual and cultural life that is easy to carry!
