Chapter 769 It's really one head, two big ones. That evening, Lu Qingyang had just returned home when he ran into the postman who came to deliver the mail.
"Qingyang, here is your letter."
"Thank you, 깊."
Lu Qingyang took the envelope.
The numbered organization name at the end of the signature made 놛's eyes narrow slightly.
Without making a sound, he opened the letter and quickly skimmed through it.
The letter was brief and carefully worded, essentially inviting me to attend a technical seminar at a certain organization next Wednesday. It included a detailed address and the name of the person who would be hosting me.
Lu Qingyang told his family that he needed to take leave.
On Wednesday, Lu Qingyang went to the address and found an inconspicuous gray building in the west of the city. There were soldiers on guard at the door, and they checked Lu Qingyang's letter of introduction and identity documents before letting him in.
Several people were already seated in the meeting room, mostly intellectuals in their forties or fifties.
The meeting was chaired by a director surnamed Huang, who was very polite. However, once the topic was discussed, Lu Qingyang realized that this was no ordinary seminar. It was clearly a technical meeting to tackle the problem of insufficient reliability of a certain type of individual rocket launcher sight in harsh environments.
At first, Director Huang wondered where this young man came from. If it weren't for Professor Qian's introduction, he would never have allowed anyone to participate in such a profound seminar. Could he even understand what he was saying?
Unexpectedly, when Lu Qingyang was speaking, he picked up a problematic scope sample from the table, pointed to a tiny reed structure inside, and said:
"Director Huang, fellow teachers, I think the problem lies here. The toughness of the metal changes at low temperatures, so the rebound of the spring after deformation is not precise enough, causing the reticle to deviate by a few micrometers. It may not seem like much, but a difference of a millimeter can lead to a huge error over hundreds of meters."
Amidst the astonished gazes of the crowd, 놛顿깊顿 continued, "Could we try a different approach? Instead of metal springs, how about using special rubber as the buffer and reset element? The low-temperature performance and deformation recovery ability of rubber might be more obedient than this lump of iron."
He also casually drew a simple structural improvement diagram on a piece of paper.
The room fell silent for a moment, then several senior engineers began to whisper among themselves.
Director Huang adjusted his glasses, and his gaze towards Lu Qingyang completely changed.
It seems that you are narrow-minded; how could someone recommended by Professor Qian be bad?
From initial politeness to seriousness: "Comrade Lu Qingyang, your idea... is very bold and insightful. We will arrange for experiments to verify it immediately."
That would be best.
Lu Qingyang thought he could go back to school and attend a class, so he left in a hurry.
Even the engineers couldn't stay and continue the discussion.
Not long after Lu Qingyang returned from the classified unit, Officer Li from the street office rushed to his door, beads of sweat still on his forehead.
"Engineer Lu, help!" Officer Li grabbed a swig of cold boiled water from the counter.
“Our suburban chicken farm is broken down again. The temperature controller you designed keeps malfunctioning every few days. Those chickens are going on strike, laying eggs very sparingly. The farm manager is so anxious he’s practically crowing like a rooster!”
Lu Qingyang laughed: "Let's go take a look."
The manager of the chicken coop sighed as he pointed to a metal cabinet.
Lu Qingyang opened it and saw that the small relay contacts inside were burnt out.
I'll go back and tinker with it for two days, and draw a new blueprint.
The relay that originally served as both a controller and a heavy-duty device was split into two: first, a small, low-pitched relay was used to listen to the thermometer's commands, and then it was used to wake up the large, sturdy AC contactor next door, which was responsible for switching the heating circuit on and off.
I also added a homemade bimetallic strip to act as a mediator and prevent the switches from being turned on and off too frequently.
After installing it and testing it, the temperature in the chicken coop remained as stable as if it were stabilized by a magic needle.
The tasks that were done on the spur of the moment weren't over yet.
Lu Qingyang saw the zookeeper adding water to the trough at regular intervals and then pondered what to do next.
I dug out an old alarm clock, disassembled the bell, connected a few gears, and even used a lever to hold the water valve in place.
The next morning, the gears turned with a click, the lever was pushed, and water gushed into the water tank, automatically stopping when the water level was full.
The zookeeper, holding the empty bucket, stood there stunned: "Good heavens, this thing is even more accurate than a crowing bird!"
After this news spread, Lu Qingyang quickly became an unofficial staff member of the agricultural machinery station.
A pig farm came to me to make piglet incubators. I installed a light bulb with a bimetallic strip on it, which automatically turns on when it's cold and turns off when it's warm.
If you want your vegetable greenhouse to have automatic roller shutters, just find an old motor and a limit switch, and you'll save the trouble of pulling the rope.
The most ingenious thing was that the humidity in one of the greenhouses was always too high, so Lu Qingyang brought over two thermometers, one for humidity and one for temperature, and connected them to the vents with levers.
When the humidity is high, the humidifier evaporates quickly and the temperature drops. If the lever tilts, it will slam open the vent.
The greenhouse technician slapped his thigh in amazement: "Your method is brilliant!"
Now, whenever there's a problem at the agricultural machinery station, they contact the local authorities, and the local authorities always threaten to strike.
Later, the head of the agricultural technology station thought about it carefully and realized that he couldn't just let people help him for no reason.
"Qingyang, what are your plans after graduation?"
Lu Qingyang was strange; although he was already a junior in college, he still had a year left and hadn't really made up his mind.
"Not yet, no rush."
"Why don't you come to our agricultural machinery station? After all, it's a public institution, and agriculture is a sector that the country is vigorously developing right now."
Lu Qingyang scratched his head: "I really hadn't thought about that."
Just then, the professor overheard their conversation and quickly pulled Lu Qingyang aside.
"Oh dear, how can Qingyang work at the agricultural machinery station? Isn't that a waste of his talent?"
The station manager was displeased: "How is this a waste of talent?"
"Qingyang has a lot of strange and wonderful things in his mind. He will definitely be doing research with me in the future."
"What do you mean? Only practice can reveal the truth, so you definitely have to follow my instructions."
"No, you have to do the research with me!"
Lu Qingyang watched the two arguing... and felt utterly exhausted.
Actually, I don't want to choose either side. After all, I'm just one person, and I really don't have the energy to do so many things.
I also have to go to pharmaceutical factories, clothing factories, clothing stores, restaurants, etc. from time to time.
Listening to the two arguing was really giving me a headache.
