Chapter 995 Your Uncle is Your Uncle
If you use a single-chip microcomputer to make an ordinary calculator, it is convenient, but it is completely not cost-effective.

Even if you can’t afford this simplified version for the time being, it’s okay, we can sell it to others!

As for scientific calculators and engineering calculators, it would be faster for today's comrades to implement them using single-chip microcomputers. Gao Zhendong also knew that the products of Factory 1274 could be used for these purposes.

"... For the latter two types of calculators, it is recommended to use the scraps that cannot be used due to manufacturing defects in some circuits such as timers and peripheral interfaces during the production process of the single-chip microcomputer, or the defective products with low working frequency due to manufacturing defects... If scientific inspection and testing are carried out, some of the scraps can also be effectively used to generate light and heat... The focus of the work should be on the compilation of single-chip microcomputer programs, that is, how to realize the planned scientific calculation and engineering calculation functions..."

Gao Zhendong had seen Red and Blue do this kind of thing a lot in his previous life, i7 became i5, i5 became i3. Of course, Blue Factory's 13th and 14th generation cylinder reduction was purely a congenital disease, and had nothing to do with this kind of reasonable use.

Gao Zhendong didn't know that his suggestion gave birth to the world's first batch of "junk men". These comrades who had no way to obtain relatively expensive microcontrollers and some who could not obtain microcontroller quotas took out microcontrollers from engineering calculators, and after careful testing, picked out those with relatively complete functions and basically normal frequency, and used them in occasions where a decent microcontroller was needed.

The 20th century was the time when nuclear weapons were invented.

On the same day, comrades from the Science and Technology Department of the 12th Ministry of Machine Building received Gao Zhendong's reply.

Looking at this reply letter, the comrades of the Science and Technology Department said: "It has to be our General Manager Gao!"

"Hey, now the reporting units can't be lazy."

"Yes, what I am worried about now is whether the applicant can withstand these requirements. It may be easy for Chief Engineer Gao, but it may be too difficult for them."

Comrades in the Science and Technology Department all know that the original proposal of the applicant to use a single-chip microcomputer to implement an ordinary calculator is actually very lazy and simple. Basically, there is not much technical threshold. Just design a box to install the full set of components, write some simple programs, and the project is completed.

But now that the topic has been tempered by Chief Engineer Gao, it has suddenly undergone earth-shaking changes.

The simplest one nowadays is the scientific calculator.

Ordinary calculators have technical difficulties in hardware, and cost reduction is achieved by relying on the difficulties in microelectronics.

Engineering computers have technical difficulties in software, but at the expense of software difficulty, more abundant and urgently needed functions can be achieved.

"There's nothing we can do about it. Chief Engineer Gao's classification and requirements for calculators now seem to be the most scientific, and can solve the problem of rapid calculations for engineers on the construction site. For this reason, there is a need for research." At this stage, engineers may still be unable to equip the site with computers, and computers are not convenient in some workplaces.

But with this thing, it's different. You can really do calculations at any time. Chief Engineer Gao has condensed all the related functions of engineering calculations together, discarded other functions of the computer, and created a portable, cheap and easy-to-use tool for engineers.

Otherwise, why do we say your uncle is your uncle?

"Indeed, without Chief Engineer Gao's adjustment, this project would have no cost-effectiveness and necessity. But now, its feasibility, cost-effectiveness and necessity have been well supported. It can be said that Chief Engineer Gao has revived this project. By the way, Chief Engineer Gao just came back from the disaster relief site, right? He was able to give us this set of things so quickly, which is simply amazing."

I don't know what he was going to say, but he changed his mind abruptly.

But what he said was not wrong. Everyone knew that Gao Zhendong went to rescue people. He had just returned and it was almost public knowledge. People at their level would naturally be able to find out.

Although his reply letter does not contain many words and the function list does not seem to be too complicated, it is impossible for someone who has not studied engineering in depth to come up with such a list of functions for an engineering calculator.

So there is only one explanation for all this. In the short time since he came back, Chief Engineer Gao has managed to raise his knowledge of engineering applications to such a high level.

Horror!
For the Science and Technology Department of the 12th Ministry of Machine Building, the next thing was simple.

"He even used the waste films from Factory 1274. Director, let me tell the applicants to come and see for themselves whether they are sure or confident. If not, we will hand the project over to other units and leave them with a scientific calculator at most."

The attitude of the Science and Technology Bureau is very clear. These are three good topics. If you can't do it, you can find someone else. However, the topics must be done. In this matter, it is impossible to save face for the applicant unit.

At most, we can leave them the simplest scientific calculator for the sake of the initiator, so that their work will not be in vain.

"Yes, that's what we have to do. You should notify them to come and claim it. Whether they can take it away or not depends on their ability."

After saying this, the director looked at Gao Zhendong's reply and marveled at the lists of functions on it: "Look, these functions proposed by Chief Engineer Gao must have been carefully considered and selected after a lot of research on the project. They are very suitable for engineering calculations. There are many that I can't understand and I don't know what they are used for."

The scope of the Twelve Ministry of Machine Building and engineering construction is quite large, so it is normal that some of the purposes are completely incomprehensible.

The comrades beside him rolled their eyes after hearing what he said. They didn't understand how he knew it was suitable. Are you just bragging? But on second thought, his director may not be trustworthy, but Chief Engineer Gao's name is well-known. From this point of view, his leader's conclusion seems to be correct.

As a leader, you have to consider the issues comprehensively!

"Oh no, oh no, notify Factory 1274 immediately. Waste chips from chip production cannot be disposed of at will!" The director suddenly remembered this pile of treasures.

"Ah! Yes, yes, yes, I'll notify them right away!" The comrades around him ran away.
-
After Gao Zhendong dealt with the backlog of matters, he immediately turned his attention back to the matter of the steel material manual. This was his daily work in the Third Factory. However, for the comrades who worked with him, Chief Engineer Gao's ability to do two things at once was something they could not do on a daily basis. They were horrified every time they saw it.

Look at what our General Gao has become.

Fortunately, those waiting for Gao Zhendong on this day included not only their internal staff, but also many comrades outside, so they did not have to be frightened for too long.

"Hello, Chief Engineer Gao, we are here as requested!"

Gao Zhendong looked up and saw a familiar face. Although he hadn't seen her for a while, he still knew her well.

It was General Wang from the Northeast Aero-Engine Institute, the comrade who had made great achievements in developing the LYP-6. He forcibly raised the flight envelope and payload of the Z-6, Z-7 and G-5 in our new model system to a position that did not originally belong to them.

And this time, it was indeed Gao Zhendong who had recently commissioned the Defense Work Committee to invite them over, just after he had communicated with the comrades in the Northeast who were working on aircraft.

Mr. Wang is an old acquaintance, and he has all the necessary credentials. The level of work he is in charge of is also high, so he passed the many internal security checkpoints and entered Gao Zhendong's office.

Several comrades from the third factory in Gao Zhendong's office packed up their work documents familiarly and left quickly. They were already used to it.

"Welcome, Mr. Wang. Originally, I should have been the one to visit you, but I just can't get away. And I can't talk to you over the phone about what I want to talk to you about, so I have to trouble you to make this trip."

Gao Zhendong still felt a little embarrassed to call someone over from far away.

"No, no, Chief Engineer Gao must have summoned us for something good. We can't even make it in time. We were supposed to arrive the day before yesterday, but we heard that you went to the rescue site, so we decided to just wait for you in Beijing."

To be honest, as Mr. Wang said this, he was wondering in his heart that Mr. Gao was really like a spider, with eight legs reaching into so many fields that even flood prevention and rescue operations had to specially transfer him.

Gao Zhendong smiled and said, "I'm really sorry to have kept you waiting for so long." Never mind whether it was for work or not, but after all, he was the one who called them over and was forced to leave them alone for two days, so there's nothing wrong in saying a few nice words.

"No matter where you are, disaster rescue is the top priority, and returning victoriously is the most important thing."

At this time, reports of the initial success of the rescue and relief efforts have been published, but the water has not yet receded, so there is no final large-scale, high-profile closing report. The water on the dam has only been rising for about 6 days, but it will take much longer to recede.

The two chatted for a few sentences, and Gao Zhendong then talked about the reason for inviting Mr. Wang over this time.

"Mr. Wang, actually, there is a very important reason for inviting you here this time. Not long ago, I went to Guizhou and Sichuan Province for work. Combining my expertise here, I have some ideas and experiences. I would like to exchange ideas with you and ask for your advice."

It’s no wonder that the cause of this incident is really closely related to Qianshan.

"Ah? Mr. Gao has a new idea? Great! Is it a new material or a new process?" For Mr. Wang, a 591 high-temperature alloy is like a tiger with wings. The places Gao Zhendong visited this time all had some special mines, so it seems that he has new ideas on materials.

Having already tasted great success on 591, he was very excited when he thought that Gao Zhendong might have new materials and specially invited him to discuss.

Hi, hi, hi, I found new materials again, comrades!
"Ah, yes, there are new materials and new processes, but that's not all I want to say..."

Gao Zhendong felt a little embarrassed. After all, what he was about to do might seem a bit presumptuous to most people.

"And more? Ah, I see! You have an idea about the engine itself, right?"

Mr. Wang recalled that when he first found Gao Zhendong about the 591 alloy, Gao Zhendong already had many insights into aerospace engines, and his insight was even much higher than that of his colleagues in his own research group.
