60s researcher

Chapter 101

"That's it." Lu Jian didn't think it was strange, and glanced at the book in his hand. It was a book about electric motors, and it seemed that he was preparing for the washing machine project later.

"Gong Lu, my condolences. How is the arrangement at home? Is there any problem?" Ye Gong's face was full of worry, and he asked cautiously.

"Fortunately, almost everything has been arranged, and tomorrow morning's meeting will start as usual." Lu Jian knew his worry. Although he and Jiang's grandparents hadn't met a few times, and their relationship was normal, this incident made him He felt uncomfortable and worried about Lu's mother. Fortunately, there were three happy events at home, otherwise he didn't know how to comfort Lu's mother.

"That's fine, that's fine."

"Then you continue to read, I'll go back first." Lu saw that there were still several places to be changed in the project, so he didn't say much to him, and went straight into the office next door.

When Lu Jian returned to his office, he sat down, took out a pen and paper and began to concentrate on his work.

The technical department at night is very quiet, only the rustling sound of the pen tip falling on the paper.

The morning sunlight fell on the ground through the window, moved slowly towards the desk as time passed, and finally fell on the eyes of Lu Jian who was lying on the desk.Lu Jian covered the sun with his hands, slowly opened his eyes, glanced at his watch in a daze, and found that it was past eight o'clock.He stood up and moved his muscles and bones. He felt sore all over his body, and kept shaking his hands and feet. He fell asleep on the table after finishing last night. Now his hands and feet are numb, which is extremely uncomfortable.

"Lu Gong?" Suddenly the door was knocked, it was Ye Gong's voice, Lu Jian hurried over and opened the door.

"Have something to eat? There is a meeting at nine o'clock." Standing at the door was Ye Gong, who was holding a deep-fried dough stick and a steamed bun. The deep-fried dough stick is very beautiful in color. This is a rare item. In this day and age, there is a shortage of oil. , Fried dough sticks are less common than meat buns.

"Thank you." Lu Jian was not polite, and simply took it over. He has worked hard for the past two days, and now he is really hungry.

"Then I'll go." Ye Gong left after delivering breakfast, and came here to deliver breakfast to Lu Jian.It was past twelve o'clock when he went back at night, and when he closed the door, he found that the light in Lu Jian's office was still on, so he knew that he must be planning to stay up all night.

"Okay." Seeing him leave, Lu Jian closed the door and went back to the room. He put the fried dough sticks and steamed buns in the lunch box, took the cup to fetch water, and took a brief wash.

After Lu Jian finished his breakfast, he checked the documents again, and went to the meeting room when it was 5 minutes before nine o'clock.

When he passed by, everyone was already there, and now there are many people in the technical department, almost 50 people, but it is very quiet inside, and no one talks.

"Comrades, there are a few things to talk about in this meeting." They were all researchers, and they didn't have so many tricks. Lu Jian walked over, looked at everyone, and started talking about things.

"The first is the issue of personnel. I know that the tasks are heavy and everyone is working very hard, but this is only temporary. A group of comrades will join our team in a few days. Everyone will be more relaxed by then." Seeing this To be honest, the current technical department is simply overloaded.Everyone often works overtime until very late, and the single rest is simply impossible to achieve. Machine inspection and maintenance are all carried out after get off work.

"It's not hard."

"It's really not hard."

"I am willing."

"..." Hearing Lu Jian's words, the people below all shouted, with smiles on their faces.

"It's good if you don't work hard. We have a lot of newcomers now. If you have any questions, you must ask them in time. You seniors should also be enthusiastic and offer help." Lu Jian saw that many newcomers inside had told each other A few words.

"Yes." There was another chorus from below.

"Okay, the second thing is about the project. We still have a harvester project in progress, and it is expected to end in one month. This project is still led by Lu Gong with a team, and everyone else is withdrawn to do it. New project." After Lu Jian finished speaking, he looked at the people below, and then continued.

"The new project is a pulsator fully automatic washing machine. Its principle is to rely on the pulsator installed at the bottom of the washing tub to rotate forward and backward..." Lu Jian posted the overall structure diagram on the blackboard and began to explain the project. Write a series of numbers on the blackboard.

"Its structure is composed of washing, dehydration, inlet, drainage and transmission parts..."

"This design impeller is injection molded from reinforced polypropylene plastic..."

Lu Jian spoke very seriously at the top, and the people below also listened very seriously, writing non-stop on the paper with the pen in his hand.

"The whole design is probably like this. Do you have any questions?" Lu Jian put down the chalk in his hand and looked at the people present. His voice was hoarse because he talked too much.

"The motors for the double barrels are two different sets. Does our single barrel have only one motor? Will there be any problem?" Seeing that Lu Jian's attitude was very friendly, someone immediately stood up and asked a question.

"The motor I designed is a single-value capacitor forward and reverse motor, which can cooperate with the deceleration clutch to complete low-speed operation during washing and high-speed operation during dehydration..."

"And I have removed the traditional belt structure this time, and I am going to use a four-stage motor, transform it into a variable frequency speed regulating motor, and use the frequency conversion direct drive..."

"Lu Gong, the AC speed control project has gone through such a long period of development and has not achieved any results. Is it impossible for you to use frequency conversion technology?" Before Lu Jian finished speaking, a person stood up, The place where he worked before was to study frequency converters, but there was no result.

"At present, high-power silicon and thyristors are being continuously developed and developed. My idea is to use thyristors to invert direct current into 0-100Hz alternating current..." Lu Jian was not panicked at all, and began to speak with a clear mind. Frequency conversion technology he I have thought about it before, and it is also very important for the air conditioning project at the end of the year.

"Lu Gong, your idea is really great." The person who refuted Lu Jian just now was completely convinced, and looked at Lu Jian full of admiration. The others were also very happy and began to discuss in a low voice.

"Don't be too happy too early. Due to the material, the working efficiency of this kind of frequency conversion is low, and it is limited to the low-to-medium frequency range. If you want to continue to improve, you must rely on the continuous development of electronic device materials." Lu Jian knows frequency conversion technology It also depends on the development of large-scale integrated circuits. He is not as optimistic as the people in the audience.

The audience fell silent for a while, and everyone didn't know what to say.

"Gong Lu, I have another question about shock absorption. How is the shock absorption part designed?" Seeing that the atmosphere was a bit cold for a while, Ye Gong got up and asked a question.

"The shock-absorbing part is the boom assembly, a set of four, the spring of the shock-absorbing part on the side of the motor is slightly longer, and the surface is galvanized..." Lu Jian also just wanted to remind the importance of integrated technology. Ye Gong did not continue to talk about other things, and started to talk about the problem of shock absorption.

After that, there was a long technical explanation and work arrangement. In the middle, the meal was directly arranged for people from the cafeteria. After a group of people finished eating quickly, they continued to study the materials of various parts of the project.

By the time this meeting ended, it was already past 40:[-] pm. Because the technical department often worked overtime, the factory manager Zhang specially arranged for a kitchen to be reserved, so even after nine o'clock, there was still food to eat.

The three of them, Lu Jian and Xu Yan, did not go with the researchers below. There is only one stove in the cafeteria, and there are too many people going now.Several of them discussed some issues in the laboratory, and they didn't go to the cafeteria until almost eight o'clock.

Lu saw that there were more than a dozen people inside when they arrived, and the chef in the cafeteria still had several dishes to fry. Seeing that they had finished ordering, Lu found a place to sit down.

"See Lu, what happened at home? There's nothing serious about it, right?" Zhao Lei has been to Lu's house several times, and has a good relationship with Lu's house, and his face is full of worry.Xu Yan and Jian Mingyuan also looked very worried. Ye Gong didn't tell them what happened to Lu Jian's house yesterday.

"The Lu family is fine, but my grandpa and grandpa passed away." Lu Jian didn't hide anything, we were all good friends, and asking this was out of concern, but Lu Jian's mood was still depressed for a moment.

"Ah, don't be sad. The old man's death is considered a happy event and a happy funeral." Zhao Lei didn't expect this kind of thing, and he left the two old men at once, comforting him a little awkwardly.But what he said is also true, a happy event, if the two old people died of natural causes, then of course it is a happy event, but...

"Yes." Lu Jian nodded, and didn't say the reason for the death of the two old people. After all, it's not a pleasant thing. Talking about it will only make others feel depressed along with him.

"Is Aunt Lu okay?" Jian Mingyuan asked this question. He was the one who spent the longest time with Lu's mother, and he was a little worried.

"It's pretty good. My two sisters-in-law and eldest sister are pregnant with babies. She shouldn't have much time to be sad now."

"Isn't it? Qin Hui is going to have a baby." Xu Yan and Zhao Lei were startled when they heard Lu Jian's words. They had been to Qin Hui's wedding before, but they didn't expect that this person who was younger than them already had a baby. .

"They've been married for more than half a year. Isn't it normal to have a baby?" Jian Mingyuan said this. Recently, he has become more and more like a normal person. You can see his emotions on his face.

"..." Xu Yan and Zhao Lei were silent, they really hadn't thought about this problem, after all Qin Hui was younger than them.

"Jian Mingyuan, is Professor Xia still with Professor Xie?" Lu Jian suddenly thought of Professor Xia and the others. He was very busy recently and had no time to go home. He didn't see Duoduo and the others this time.

"Yes." Jian Mingyuan glanced at him, as if he was surprised that he didn't ask this question suddenly.
