Chapter 1940 Relay

"I am an apprentice in the General Machinery Factory."

"I have no place to live for the time being. The attic above you is still vacant, can I live there? Don't worry! I will pay you the original rent as usual."

……

Qian Yuzhi is usually not a person without ideas, but at this time he seemed to be led by the nose. Li Jianai led the conversation, and then showed Qian Yuzhi his work permit and ID card. Within a few minutes, things went like this Decided.Li Jianai picked up a small rattan box at the end of the bed and walked towards the simple stairs, "Bring me the bedding, thank you."

At this moment, Qian Yuzhi heard a rumbling sound coming from her belly, Li Jianai's face immediately flushed, she turned her head and gave Qian Yuzhi a preventive look, probably meaning that Qian Yuzhi dared I want him to look good when I mention it.Qian Yuzhi had no choice but to pretend not to hear, picked up the bedding and followed her.

The attic used to be his sister's bedroom, and the bed and furniture were all ready-made.The inside was cleaned cleanly - it can be seen that Li Jianai is a very nice tenant.

"Okay, I'll live here reluctantly." Sitting on the bed, Li Jianai said, "I won't return the key to you. I usually eat in the cafeteria, and I definitely don't cook on fire—so don't even think about it. Let me cook, even if I pay for the food, I won't do it..."

"I also eat in the factory." Qian Yuzhi felt aggrieved, and out of nowhere, he deliberately took advantage of her. He suddenly remembered something, "This... we are different from men and women, we live in the same place..."

"Hey, I didn't expect you to be quite old-fashioned. Didn't you live with girls in the past? There are a lot of girl things in this house."

"That's my sister..."

"Since you care so much, I'll be your younger sister—cousin. I'll visit you and stay with you temporarily..."

Qian Yuzhi didn't know whether to laugh or cry, this girl who came out of arts and sciences was really bold and uninhibited, and she just lived under the same roof as a man of similar age?Is she not worried at all?Or is she too convinced that she is a modest gentleman?
Qian Yuzhi found that he was surprisingly kind today, he was polite enough not to turn Li Jianai to the police station, and he even promised her to rent a room.In the past, both he and the girl could be regarded as "***". Although the countryside doesn't pay much attention to these things, a man and a woman living in the same house are actually a married couple.Could it be that this girl is really interested in him?
Looking at Li Jianai's uniform, he thought of Teacher Xiao Feng again, and his heart was a little restless, just like every teenager who entered puberty.

"I'm going to bed first." Qian Yuzhi felt his face warm up, and he hurried downstairs.

Feng Nuo walked towards the train station out of breath. He was going to take a small train to the steel factory in the Maniao Industrial Zone.After walking briskly for less than 10 minutes, he was a little tired and out of breath.

"I can't, I have to exercise..."

Feng Nuo said to himself silently.

He is probably one of the most nerdy people among the elders.The executive leaders of the various institutions of the Senate have to spend a lot of time on weekdays to "go down to the grassroots" for inspections, but he sits in the office all day.To say that exercise means walking back and forth between the computer room and various offices.

When he got to the platform, he was already sweating profusely.
"It won't work like this. The revolution hasn't succeeded yet. If the capital collapses first, it will lose a lot."

Feng Nuo said to himself silently.Still involuntarily sat down on the waiting bench.

Nowadays, there are very few people on the platform during the peak hours of commuting from time to time, and most of them are correspondents from various departments carrying special communication backpacks.He slumped on the bench, thinking of what a certain electrician veteran said just now——he felt very upset.

The current punched card machine system is a special-purpose machine for population census, not a general-purpose machine.Therefore, in the design of the tabulating machine, only the functions of counting the number of cards and counting the number of cards meeting a certain perforation condition are reserved - the latter can actually be realized by adding a sorting machine to the former.But it doesn't have the accumulator or even multiplier functions of the old space-time tabulator.Feng Nuo also knew that this allocation reduction was a bit of a shoddy job, but the logic required to implement the accumulator with a relay was a bit complicated, and the relay was not known yet.So he decided not to do the accumulative function. Anyway, the census is one card per person, and this function is probably only used for the calculation of the average age. At that time, it will be better to run it a few times with the sorting machine.

Unexpectedly, during the meeting just now, a keen old man saw this problem at a glance, and said, "Your tabulating machine can't add up, what's the difference from a banknote detector?" This is a bit harsh, but it is not unreasonable.Although Feng Nuo cursed secretly in his heart, he could only joke that "the technical content of the banknote detector is much higher than ours", and fooled around.

Fooling the past is fooling the past, but Feng Nuo began to seriously consider whether to use the accumulator.However, in this way, the performance and volume requirements of the relay are higher, and a better magnetic core, thinner winding wire, and more effective insulation layer are probably required.He was quite confused, and planned to ask Faraday, who was not at the meeting today.

Feng Nuo walked around the electric and electrical equipment factory, only to know that Faraday went to the steel factory to check the production of silicon steel - the quality and stability of silicon steel production has always been a sore foot for Diankou.

He walked around the steel company, and finally found Faraday in the workshop.His hair was disheveled, and his face and overalls were covered with soot.

Hearing Feng Nuo's question, he thought for a while, "1mm copper wire has long been available, 0.5mm should be available, 0.1mm... I guess it's difficult, we haven't used it before - you'd better confirm with the machinery factory a bit."

Feng Nuo thought that the small relays in the old time and space should generally use winding wires with a wire diameter of less than 0.1mm. I don’t know how much impact it will have if the wire diameter is 0.5mm. I have to ask Feng Shan to calculate it when I get home.Next, he asked about insulating materials.

"Insulation layer? I have always used asphalt and mica for insulation. I have also tried wrapping with silk, cotton, paper, and glass. Then do it with oil immersion treatment."

"Have you been using asphalt insulated wire?" Feng Nuo was very disappointed. The working voltage of the relay is low, the wire diameter is small, and the number of turns is large. It is neither necessary nor possible to use the same insulating material as the motor. "What about the enameled wire?" He asked. Ask.

"Of course I thought about it before. But this thing can't be seated by hand. We wanted to ask the machinery factory to produce a set of special enamelling machine equipment for us, but the enamelled wire lacquer has been lacking. What we do here, the electricity There are so many things involved in the manufacture of electrical equipment, let’s let go of this little thing first..." Faraday scratched his head and replied, "Why don't you try it yourself? I still have some information for your reference. "

Feng Nuo thought to himself that this technical bottleneck is really to grab one and bring out a bunch. If this continues, he will have to start from mining and planting trees. What about the power of the agreed-upon large industrial system?He said very hesitantly, "But with my background in IT, I'm at my limit when it comes to relays. Anyway, it's still a weak current system. This chemical industry..."

Before he finished speaking, Faraday rolled his eyes angrily, saying that the labor and management did not study metallurgy, and they have not been squatting in the blast furnace every day for more than a year.

Feng Nuo choked on this sentence and lost his temper, so he took some enameled wire production materials from Faraday and returned to Bairen Machinery General Factory.

After returning to the machinery factory, he did not go back to his office first, but went to the office of Sun Li, the director of the precision machining workshop, intending to borrow some workshops, equipment and manpower from the machinery factory, and then talk about making enamelling machines.

This time it went well. Sun Li said that the factory building is not a problem. An old workshop next to the computing center can be vacated, but they don't have enough manpower, so they can only send two or three people there first. Equipment and power can be applied for. As for the paint For charter flights, the machinery factory is always at full capacity. He suggested that Feng Nuo wait for the insulation paint to be available before discussing it.

After Feng Nuo left, Sun Li rang the bell to call Guihuamin's section leader and asked him to assign one or two workers to Feng Nuo.

"Recently the task is heavy, try not to affect the normal production of the workshop." Finally, he seemed to add something casually.

"Yes, chief." The section leader walked out knowingly.He returned to the work section, and waved to Qian Yuzhi who was still in a daze, "Qian Yuzhi, come here."

Feng Nuo didn't know that the section leader sent over Qian Yuzhi, who he thought was the most incomprehensible, and then he went to the standard parts factory to ask about copper wire drawing.

At present, the industrial port has the ability to produce electrolytic copper, and at the same time produce electrolytic copper copper wires of various diameters.However, the veteran of the standard parts factory said that there is no 0.1mm wire drawing machine at present, so the smallest diameter is also 0.3mm.But you might consider trying it out.

"When will it be made?"

"The machine itself is not difficult, the main problem is the accuracy and strength of the hole-drawing plate." The veteran replied, "The accuracy is actually not a big problem. The big deal is to apply for a CNC bed, but the strength of the material is a bit weak. No."

The basic principle of the wire drawing machine is very simple. The rod passes through the tapered hole drawing plate of different diameters, and is stretched repeatedly from thick to thin.The principle sounds simple, but doing it is another matter. How to open the 0.1mm taper hole, and the strength of the orifice plate must be strong enough to withstand the pulling force without deformation.Speaking of it, it is another complex system engineering, which needs to be supported by many enterprises.This has to wait until the year of the monkey?
Feng Nuo had no choice but to go to the Planning Institute to apply for a small amount of 0.1mm and 0.05mm wire diameter enameled wires brought by the old time and space, and also applied for a lot of the thinnest 0.3mm copper wires that this time and space can produce by itself, and Faraday Institute. Some other materials mentioned in the given brochure.Fortunately, although Feng Nuo does not work at the headquarters of the Planning Institute, his personnel relationship is still there, and he often shows up in meetings and other things. passed.
