Siheyuan: Starting from a fitter

Chapter 123 Multimeter ([-])
At this time, Yan Jiefang walked over cautiously.Li Guocheng looked at his wretched look, and wanted to have a good chat with him, since he wanted to hang out with him in the future, he couldn't embarrass him.

"Liberation, what do you think?"

"What do you think?" Yan Jiefang looked innocent.

"Your body language reflects your inner thoughts," Li Guocheng explains.

"Body language", Yan Jiefang's performance was even more confused.

Forget it, Li Guocheng didn't bother to explain to him what body language was.

"In the past few days, you have been acting cautiously. This is true in itself, but you have to master the standards, otherwise you will look insignificant. You are here to work, study, and grow, not to be a grandson." Li Guocheng said directly Make it clear

After hearing Li Guocheng's words, Yan Jiefang straightened his back, but his face showed a tangled and constipated expression.

"Respect for seniors comes from the heart and cannot be a mere formality. As long as you truly respect the other person, there is no problem in whatever you do. If you are not sincere, don't force yourself. Be frank and upright with people; be upright with things. Be careful, careful and attentive." Li Guocheng simply said it more thoroughly.

"An old saying goes: A road can tell a horse's strength, and time can tell a person's heart. Stay true to your heart, and everyone can understand some of your tempers; but if you are false, you will only get away after being seen through." Li Guocheng couldn't hold it in anymore, and he went too far. .

At this time, Yan Jiefang fell into deep thought and sat there in a daze.Li Guocheng ignored him. Everyone is responsible for their own choices, and others cannot replace him.

When Wu Liankui came and left in a hurry, he knew something was wrong. Fortunately, there was a coolie here.

"Jie Cheng, hey! Jie Cheng!" Li Guocheng shouted several times before Yan Jiecheng's eyes focused again.

"Ah, Brother Li, you call me." After Yan Jiefang woke up, he clearly realized something and acted much more normally, less feminine and calculating.

"From now on, the production and follow-up research of the multimeter will be left to you. I will give you the circuit diagram and device layout diagram later. Now you can watch me do it first, especially note down the length, wiring method and routing of each enameled wire. "Order", the pot must be thrown out.

Then, Li Guocheng reported the name of the device and its pin number, the connection relationship with other devices, the length of the connection, and the order and sequence of the wiring.In order to take care of Yan Jiecheng, I deliberately slowed down and showed him the circuits, devices and wiring carefully.

The two of them were busy. In fact, only Yan Jiefang was sweating profusely and in a hurry, while Li Guocheng was very leisurely.

After an unknown amount of time, two people, Li Huaide and Wu Liankui, hurriedly walked into the laboratory.

"Hahaha, Xiao Li, you gave me another surprise. I just reported the single crystal ingot to the department, and now I am still worried about the output of the vacuum furnace and the wafer output."

He spoke of pain, but the smile on his face revealed his heart.

Li Guocheng knew his purpose, took the multimeter and handed it to Li Huaide.

Li Huaide carefully took it in his hand, turned it over and over to appreciate it, and made an incomprehensible murmuring sound from his mouth. His whole face turned into a chrysanthemum.

"No. [-] in the world! No. [-] in the world! We need such an invention so much now." He smiled and shed tears.

At this time, Wu Liankui was a little at a loss. He hid behind Li Huaide and tried to squeeze out some tears. Unfortunately, he had not studied "Actor's Qualifications" and his efforts were in vain.

Li Guocheng understood the mood of his generation very well. No matter how many fights they usually had, his desire for the country to become stronger was purer than that of later generations.

Li Guocheng took out a brand new handkerchief from his "pocket" and handed it to Li Huaide, "I will make you laugh."

Li Huaide just smiled reluctantly and didn't make any other explanations.

"Let's go to the ministry together. If you don't go, Xiao Li, we won't be able to explain it." Li Huaide's face was filled with confusion. The previous principle of confidentiality could no longer be maintained today.

"Director, I suggest that in a few days, I am working on integrated chips for FM and AM radios. If successful, the cost will be reduced by more than half, the circuit will become simpler, the volume and overall cost of the radio will be reduced a lot, and its lifespan will be longer. Longer, lower power consumption."

Li Guocheng's words were simple and calm, and the two people around him were already going crazy. They couldn't understand the integrated chip, but they understood the benefits.

"What is that integrated chip?" Li Huaide grasped the key point.

"It is to integrate the buffer, three-stage amplifier, driver, and peripheral resistors and capacitors used in the radio onto a wafer block, and then package it. Inside is the core semiconductor circuit. For the sake of image, I called it a chip."

Li Guocheng looked at the two people who were still confused, took out a radio drawing, pointed at it and said:

"You see, these 8 triodes and 1 diode, except for the two driving triodes, the other 7 tubes are integrated into one chip, the yield is comparable to that of a single transistor, but the reliability is improved. A lot has been done, and it used to require 7 packaging processes, but now it has become 1, and the cost will drop a lot.”

"I understand it when you explain it this way. The most expensive thing in radios is definitely the transistor. As long as we can improve the yield of the chip, the cost will definitely drop a lot," Li Huaide said with emotion.

"What a genius design and genius idea." Li Huaide was completely convinced. He didn't expect that a political investment at that time would now give him such a big return.

"By the way, this one should be number one in the world," Li Huaide carefully confirmed.

"If nothing else happens, he seems to be number one in the world." Li Guocheng was not sure.

"Hahaha, even if he is not number one in the world, he should at least be on par with the world." Li Huaide was very perceptive and quickly came to a conclusion from Li Guocheng's answer.He is worthy of being a ruthless man who has gained a higher status through countless struggles.

This is a personal talent that cannot be learned. Li Guocheng secretly admired it.

"Okay, from now on we will do our best to do the logistics, and you can do research with peace of mind. I look forward to your success." Li Huaide made a prompt decision and gave Wu Liankui a task on the spot. He only had to use his mouth, but Wu Liankui had to move his legs.

Li Guocheng also didn't expect that from then on, their laboratory would eat Xiaozao for several days. Every time, Wu Liankui took Tang Danian back to the laboratory from the kitchen.

As soon as Li Huaide left, Section Chief Wu of the Technical Section came in with a roar.

"Xiao Li, I've confirmed it. You have something good here. Take it out quickly and let me see it." Section Chief Wu was like a prostitute entering Yihongyuan, bah bah bah. . . , he must have entered the treasure place, his face full of eagerness.

Li Guocheng once again reluctantly took out the multimeter and explained it to Section Chief Wu.Section Chief Wu was very knowledgeable about technology, and he immediately started swinging on the spot. His excited face changed from a chrysanthemum to a Shar-Pei face, and he was almost drooling and shaking.

Section Chief Wu held the multimeter and refused to let go, claiming that he would take it away.

"Chief Wu, this is the first multimeter and it has special meaning to me," Li Guocheng said solemnly.

As a person engaged in scientific research, Section Chief Wu understood Li Guocheng's feelings very well, and reluctantly handed it back to Li Guocheng.

"Don't worry, I will definitely give you an identical multimeter tomorrow," Li Guocheng promised.

After confirming repeatedly, Section Chief Wu turned around helplessly, as if he had lost his most beloved item, and left the laboratory without looking back, and then went straight to Li Huaide's office.

Li Guocheng called over Yan Jiefang, who acted as a transparent person throughout the process, and continued to assemble the multimeter.

After almost an hour, the assembly of the circuit was finally completed. Regardless of Yan Jiefang, Li Guocheng completed the welding of the pins and then threw it to Yan Jiefang for him to study.

Li Guocheng sat down in front of the drawing board, "copied" the layout diagram in his mind onto the drawing paper, and then threw it together with the circuit diagram to Yan Jiefang for him to compare and study.

Midway, Yan Jiefang wanted to understand the principle of the circuit, but Li Guocheng ignored him. With Yan Jiefang's current knowledge accumulation, it is still difficult to understand the principle of a multimeter.After this stage is over, we will systematically give them some make-up lessons.

At this time, Li Guocheng was hard at work carving the casing of the multimeter. Of course, the wood could no longer be made of small-leaf rosewood, but a piece of elm wood in the laboratory.

Li Guocheng finished the sculpture before get off work, and Yan Jiefang was sweating profusely in mapping and revising the records.Asked him if he wanted to bring food and said he wanted to go home to eat, Li Guocheng ignored him, picked up his lunch box and walked to the nearest cafeteria three.
