Scholars in the courtyard.

Chapter 1880 Professionals are different

In the afternoon, Yang Xiaotao drove to the Seventh Ministry of Machine Building.

In front of the gate, Yang Xiaotao saw Han Sanfeng waiting and smoking, so he quickly stopped the car.

The last time I came here, I felt that the gate of the Seventh Ministry of Machine Building was a bit shabby. Not only was it bare and had nothing on it, but the sign hanging on it was also made of wood. It was several levels lower than the First Ministry of Machine Building.

When Yang Xiaotao got out of the car and saw Han Sanfeng coming over, he immediately stepped forward and said with a smile, "Uncle Han, you came all the way here to wait for me."

Han Sanfeng also laughed, "That's right, I was called out by the chief, waiting here to welcome the important person."

"No, no, I'm not a big shot."

Yang Xiaotao waved his hand quickly, then asked Han Sanfeng to get in the car and drove inside.

The last time I came here, I knew that the Seventh Ministry of Machine Building was very large. If I walked, it would probably take ten minutes to reach my destination.

The two of them walked inside in the car and chatted, "Uncle Han, have you been busy recently?"

"Busy, I'm always busy."

"You've heard about my visit this time, right?"

"I know. The chief said, we need a calculator too."

Han Sanfeng almost let the cat out of the bag, but when she saw that Yang Xiaotao's expression didn't change, she reacted immediately.

In fact, he felt that there was no need to do all these empty things. If it existed, it existed, and if it didn’t, it didn’t exist.

With Yang Xiaotao's intelligence, he should have seen it a long time ago.

He felt uncomfortable with this kind of pretentious behavior.

But there is no way, he has to listen to his leader's words.

What's more, they said that the 50,000 yuan was research funding for them.

Cough
The calculator is with them, so this matter has something to do with them as well.

"Uncle Han, you have to help me this time and pick out a few capable ones for me."

Yang Xiaotao ignored Han Sanfeng's thoughts and asked, "The two you calculated for me last time were pretty good. Can you help me run them?"

"Last time? Are you talking about Xiao Wang and Xiao Liu?"

"I don't remember, but they felt pretty good."

Yang Xiaotao forgot the names of the two people, but last time they were able to derive several combinations of alloys through calculations, and then asked the Alloy Research Institute to make them, which shows that the other party has real talent and knowledge.

Han Sanfeng was also thinking about it when he heard Yang Xiaotao say this. Old Wang had told him before that he would give it to two people, but he could decide who to give it to.

At this moment, Yang Xiaotao took the initiative to mention the two of them, which made him a little embarrassed.

Because these two people, although young, are smart and have solid math skills, and are the talents he is optimistic about.

If I gave this to Yang Xiaotao, I would feel a little reluctant.

But on second thought, the project itself is here, and the two of them are not leaving the Seventh Ministry of Machine Building, they are just helping to set up a project, and they just have multiple identities.

"You are really good at choosing. Wang Kun and Liu Yongqiang are considered young talents in our area. They are very talented in mathematics."

"Haha, of course. The person I like must be good."

"Well, they are all here with us anyway, so it's okay to give them to you."

"Then it's settled."

"As long as you can convince them."

"it is good!"

The two talked and then came to the front of the office building.

Han Sanfeng then got out of the car and led Yang Xiaotao to the office.

In the room, when Mr. Wang saw Yang Xiaotao, he did not look cold, but approached him warmly, "Welcome, welcome. Our conditions are simple, please don't mind."

"This is a place full of talented people and beautiful scenery. If this is considered rudimentary, then our machinery factory would be like a scrap collector."

"I just love your ability to talk nonsense."

Old Wang patted Yang Xiaotao's arm and said this, and the two smiled at each other.

"Okay, let's get down to business!"

"I've discussed this matter with Lao Han on the way!"

Yang Xiaotao nodded, "I need two people to help, and Director Han has agreed."

"Well! Since it's all settled, let me also say that if we are going to do it, we must do it with the goal of success."

Old Wang looked at Yang Xiaotao and Han Sanfeng, "It's not that we use your money, but our people and machines. It feels like we are working for you and for us."

"This money and this machine are, after all, state property."

"It's just that we use it, so we have to be worthy of the country and the people."

Yang Xiaotao nodded, "Don't worry, we have to do it well."

Han Sanfeng also nodded, "We all understand what the commander said. We are all here for the same goal."

Elder Wang nodded, "I have said what needs to be said. It is up to you to do what needs to be done."

"Do it well."

Both nodded.

Afterwards, Yang Xiaotao took out the written report, and Mr. Wang read it personally. Then he gave it to Han Sanfeng. After reading it, the other party felt that there was no problem, so he signed the report and used his seal.

Yang Xiaotao also signed on behalf of the machinery factory and stamped the factory's seal.

There were two copies, one for Yang Xiaotao and one for Wang Lao, and the cooperation was completed.

The report pointed out that the Machinery Factory cooperated with the Seventh Ministry of Machine Building to establish a "Calculator Research Group".

It stipulates that the Seventh Ministry of Machine Building is responsible for providing aspects including but not limited to personnel, materials, machines, etc.

The machinery factory must provide the funds needed for the research in accordance with regulations.

The monthly fixed amount is 50,000 yuan.

Until the project research is successful.

The report also stipulated that the ownership of the research belonged to the Machinery Factory and the Seventh Ministry of Machine Building only had the right to use it.

In addition, Yang Xiaotao's identity as the person in charge was also clarified, and the team members are Wang Kun and Liu Yongqiang for the time being.

"Director Han, take him to have a look and make the announcement while you're at it!"

After Mr. Wang finished the project, he sent Yang Xiaotao away.

The two left the office and then visited the workplace under the guidance of Han Sanfeng.

The workplace of the future computer is in the Han Sanfeng Computer Research Center.

Han Sanfeng brought Yang Xiaotao in and saw many people walking around. They all had one thing in common, that is, they had a blue clip on their hands, and everyone had their own goals and walked with a clear purpose.

Even when he met Han Sanfeng, he would just stop for a moment and call her "Director", then continue with his work after saying hello.

After walking for a while, the two of them came down the stairs. Yang Xiaotao felt that they were in the underground. There was a vibration sound of machines around them. "This is our work area."

Han Sanfeng pointed to a long row of houses inside. At first glance, it looked like a workshop, very spacious, with rows of iron cabinets placed on it.

Yang Xiaotao understood that this was the place to study computers.

"Isn't it cool?"

Han Sanfeng walked in front and laughed, and Yang Xiaotao nodded.

“How many air conditioners have you installed?”

Han Sanfeng held up two fingers. Yang Xiaotao guessed that it was definitely not two, so he asked in a low voice, "Twenty?"

Han Sanfeng shook his head, "Two hundred!"

"These two hundred units are underground. This is just one floor. There are two more floors below."

"Oh! It's so big!"

"This is just the initial stage. Two more layers will be dug out later."

Yang Xiaotao nodded and said, "With so many machines running at the same time, it must use a lot of electricity."

"Yes, the power consumption is indeed quite high. The daily maintenance is a considerable amount. If there is an emergency, the power consumption will be even higher."

As Han Sanfeng introduced, Yang Xiaotao nodded in response while looking at the instruments beside him.

After walking for a while, Yang Xiaotao asked, "Uncle Han, this is a transistor, right?"

Han Sanfeng paused, then nodded, "Yes, this is a transistor computer."

Then he looked at Yang Xiaotao and said, "Last time you said that transistors can only be regarded as a transition, and integrated circuits are the mainstream of development."

“I feel the same way about that.”

"The third underground floor is where we do research. We plan to study integrated circuits. Your calculator also uses integrated circuits, right?"

"Yes, but the calculator needs to be simple and not too complicated."

"I know, simple addition, subtraction, multiplication and division, right?"

Yang Xiaotao nodded and then asked about the development of integrated circuits.

Han Sanfeng pondered for a moment, thinking that Yang Xiaotao was also the project leader, and he would have to know some things sooner or later.

"We are researching integrated circuits. Although the progress is slow, we can still make simple circuits."

“What about the display screen?”

"You mean the device of expression?"

"Yes, can you make it? It would be best if it were LCD."

"liquid crystal?"

Han Sanfeng smiled bitterly, "Of course we know that liquid crystal is the best, but we have made many requests to local governments, but no one has been able to research liquid crystal."

"So how do you plan to make the display device?"

"We haven't thought about it yet, but we can't compromise on this matter."

Han Sanfeng said helplessly, and then changed the topic to the calculator, "The calculator you are talking about should be a simple small computing device."

Yang Xiaotao nodded. "Yes, we don't need too many functions. We just need to complete addition, subtraction, multiplication and division. There is no need for storage, so a simple circuit board will do."

"Yeah! That makes it much easier."

When Han Sanfeng heard Yang Xiaotao say this, she suddenly felt that this calculator was quite promising and became interested.

Of course, this seems simpler than a computer, but it is relative.

It’s not easy to really do it.

At least not in the near future.

As the two walked, Yang Xiaotao asked about various situations. Some of the things he knew only existed in his memory, so his specific knowledge was definitely not as good as Han Sanfeng's.

But when you discuss with professionals, the effect is different.

As long as you raise your doubts, the other party will always be able to think of a solution, and even if it is inappropriate, they can provide reference opinions.

"Uncle Han, you said that calculators don't have LCD screens. What's the best replacement?"

"This is simple. We can use the same method as a TV screen. They all use circuit boards anyway. Maybe it will work if we give it a try."

After hearing this, Yang Xiaotao thought of the TV at home.

Also coming to mind are some things from past lives.

Every time in the middle of the night or early morning, I would see a black and white test picture with circles and squares, and a timer below. Every time I opened it, I hoped that time would go faster and the picture would appear earlier.

The screen projection of this type of TV is actually controlled by a circuit board.

There are various components on the circuit board, such as transistors and capacitors. They are soldered together one by one and a circuit board is formed when power is applied.

Then, through unique manipulation methods, the image can be expressed on the screen.

However, the welding technology at that time was very crude, and it was inevitable that parts would become loose.

Yang Xiaotao remembers that when the TV at home was playing, the screen would often become distorted. At that time, the old man would walk up to the TV, tap the back cover twice, and it would basically be fixed.

At that time, this method of taking pictures of the back cover of a TV in various ways became a necessary skill for almost everyone.

All this shows that this path is feasible.

"Then give it a try first."

"By the way, how do you think we should use the processing device?"

"This is not difficult. You want convenience and don't need storage. So this is different from the binary system of computers. You can use the ten-digit system, which is also convenient for input and display."

The more Yang Xiaotao listened, the more excited he became. As Han Sanfeng explained, he felt that the direction of his research became clearer and clearer.

"Uncle Han, why don't you take the lead in this work?"

Han Sanfeng was expressing his own views when he suddenly heard Yang Xiaotao say this and was stunned.

Seeing Yang Xiaotao's serious look, he quickly waved his hands and said, "No, it's not that I don't want to help you, it's just that I have a lot of things to do and I don't have the energy."

"You don't need to put too much energy into it. It's still with you anyway. You can come and take a look when you have time and help out with some advice."

"Uncle Han, just consider it as a favor."

"This"

Han Sanfeng was a little hesitant, not knowing whether he should agree.

In fact, after learning the whole story from Mr. Wang, he felt a little uncomfortable.

Although it sounds good, the two sides cooperate in research.

But when it comes to actually doing it, they are so busy that they don't have the time or energy to work on this calculator.

I don't know if this is a trick.

Seeing Yang Xiaotao's sincere look, Han Sanfeng was not as thick-skinned as Mr. Wang after all, so he nodded gently, "Okay, I'll take care of it when I'm free."
