Chapter 69 Instructions and New Item "Ask for a Monthly Ticket"

Fan Wubing's idea worked well. According to Fan Heng's feedback, in the recent period of time, the cadres and workers of Pingyuan Factory have shown great enthusiasm for work.

"It seems that public opinion propaganda is indeed very important, no wonder the status of the Propaganda Department is so high." Fan Wubing said to Fan Heng.

Fan Heng flipped through the materials and replied casually, "The recording itself is just a problem of restrictions. Now the restrictions will be lifted, and there is no technical problem at all. Apart from continuing to produce a small number of single-player orders, most of our production capacity is limited. It has already invested in the research and production of the all-in-one recorder, and the machine has basically been finalized, and now it is mainly working on some test problems and external corrections." Fan Heng brought the manual of the new machine to Fan Wubing to look at.

Fan Heng spotted the problem at a glance.

The Pingyuan factory still adopted the old method in the manual of the new Walkman. The manual is only two thin pages, the printing is average, and there are two circuit diagrams on it, as well as the contact number of the manufacturer and the address of the after-sales service site. No reading** at all.

"This is your manual? What does this explain?" Fan Wubing was a little speechless.

"Is there something wrong? Our instructions are very detailed, and there are two circuit diagrams." Fan Heng felt a little strange.

"Ah - ah - ah -" Fan Wubing screamed for a while, then he breathed a sigh of relief, "Hey, bring some paper here! I'll let you have a look, what is the real manual! "

It took a full afternoon for Fan Wubing to organize the things he came up with. After categorizing them, he found that there were more than a dozen pages of paper. If illustrations were added, there would probably be a hundred or ten pages of explanations. It covers a lot of knowledge points, even the most basic single player principle is involved. For example, the description of a recording key is as long as two pages, which is completely based on the later computer manual, but it is both informative and interesting, making people read it with gusto.

After Fan Heng saw the manual that Fan Wubing took out, he was immediately attracted. After reading it intently, he let out a long breath and said, "I really didn't expect that the manual could be written like this!"

Don't say that Fan Heng has never seen such a manual, but most people in China have never seen such a detailed manual. At that time, the manuals of domestic products were basically just one page, and some TV manuals were How can ordinary people understand a circuit diagram?

"Humanization!" Fan Wubing stretched out a finger and said to Fan Heng, "Humanization is the key to making products! What we need to do is not just products! We want to create our own distinctive brand! Whenever When people see any product brochure, they must think of the famous name Lei Ting! This is our goal!"

"good,

I also believe this is a different idea! At least after ordinary people have read it, they will not have even the slightest obstacle to using our products! I will arrange for the people in the printing workshop to get it tomorrow! "Fan Heng took it for granted.

Fan Wubing reminded, "We must pay attention to ensure the printing quality! It is best to use color pages!"

"This one is more difficult! I'll try my best to arrange someone to do it!" Fan Heng scratched his head and said.

The printing factory still uses lead type printing, and the typesetting is quite troublesome. Fan Wubing remembered the computer word processing system he used later, which was so convenient. Can't help but feel a little nostalgic.

Fan Heng coughed and frowned.

Fan Wubing looked up and found two blisters on the corners of his father's mouth, and his lips were also very dry.

Now is the autumn season, the weather in the north is very dry, and the work in the factory has been very busy, and Fan Heng is anxious to get angry because of the Japanese manufacturers entering the country, so he has not had a good rest, and finally got angry.

"Dad, you're on fire!" Fan Wubing said sullenly.

"Oh! I forgot to take the medicine again. The base of my tongue hurts these two days." After being reminded by his son, Fan Heng realized that he hadn't taken the medicine yet, so he took out a few pills from his coat pocket.

"Three pornographic tablets! It won't work if you eat it too often—" Fan Wubing said.

"What can I do?" Fan Heng replied, "The house is very dry during this time, and I have put several basins of water in the room, but it doesn't help! It would be great if it rained!"

The air is dry! this problem!

Fan Wubing's head suddenly had a flash of inspiration, and a question came to mind!

"Hahahaha——" Fan Wubing patted the table and burst out laughing, "The air is dry! This is another way to get rich!"

Fan Heng has long been used to his son's surprises, seeing him so crazy, he knew that the boy must have thought of something again. So he asked, "Seeing that you are so happy, isn't it because you saw blisters growing on your father's mouth?"

"How can I be so sinister?" Fan Wubing's enthusiasm remained undiminished, "I thought of a way to make money. Aren't you worried that the Walkman business can't support you? Then how about we cooperate on another project?"

"Tell me. What's your idea?" Fan Hen suddenly became interested. He knew that his son. But he has never let himself down. Since he said that there is a way to make money, there must be money to be made!

"Air humidifier!" Fan Wubing wrote these big characters on the paper.

"Air humidifier? What is this?" After hearing this, Fan Heng felt that this thing was used to improve the humidity in the air, but he had no idea how to achieve it.

However, Fan Heng touched the big bubble on his mouth, thinking that if he could really make this thing, it would be really useful! The only thing to worry about is that the price is too high, otherwise, there is absolutely no need to worry about the sale of this thing.

Household air humidifiers actually turn alternating current into direct current through step-down and rectification of a transformer, and then convert the direct current into high-frequency alternating current through an oscillating circuit and add it to the sonic atomizing head. This sonic atomizing head is actually a ceramic oscillator. A device has a characteristic that applying an external force to deform it will output a corresponding voltage and current, otherwise applying an alternating voltage to it will produce a corresponding deformation, that is, vibration. In this way, the ceramic oscillator generates acoustic vibrations under the drive of high-frequency voltage to atomize the water, and then sends the water mist out through the fan to achieve the effect of humidifying the air.

Fan Wubing knew that the humidifier achieved its function through the sonic atomizing head, but he really didn't know how the atomizing head works. But sound waves are not too difficult to get. I believe that there will always be people who study this aspect, and go to the relevant departments to inquire. It is estimated that the problem is not big.

In fact, domestic technical reserves are not weak, what is lacking is only the power to transform technology into practical products.

After receiving Fan Wubing's reminder, Fan Heng went to the technical department to inquire about humidifiers, and it turned out that this thing really exists, and it is widely used in industrial environments.

Generally speaking, in modern industrial production and scientific experiments, the degree of attention to air humidity is relatively high. If the humidity cannot meet the requirements, it will cause different degrees of adverse consequences. For example, in textile factories and printing factories, the humidity is average. It is required to be greater than 60%Rh, otherwise, all kinds of dry dust in the air will easily cause fire.

The scale of industrial humidifiers is generally large. It uses the saturated steam of the steam source to move laterally in the nozzle jacket, enters the steam chamber, and reduces the steam. In addition, the inertia effect separates the condensed water contained in the steam. The condensed water outlet at the bottom of the steam chamber drains out. The steam separated from the water enters the preheated drying chamber to filter and separate the remaining water in the steam. The dry steam enters the nozzle through the regulating valve and is sprayed out from the nozzle hole with a noise-absorbing metal mesh to achieve Humidification of the air.

But if it is for home use, it is definitely impossible to make it so complicated. Fan Heng also found the working principle and samples of the sonic oscillator. He tested it with cold water according to Fan Wubing's description, and it really can atomize part of the water. , as long as you adjust to the appropriate water flow and input power, there is no problem at all to realize the home atomizer.

After Fan Heng's experiment was successful, he didn't care to wait until he got off work, so he ran back home and told Fan Wubing about it.

"Hehe, so my idea can still be realized?" Fan Wubing felt very amused when he saw his father's enthusiastic expression.

Fan Heng touched the big bubble at the corner of his mouth, and said to Fan Wubing, "Anyway, no matter whether I can sell it or not, I have to make one myself first, and this house is really too dry!"

Fan Wubing nodded his head, deeply agreeing.

Dryness is the enemy of health. It will not only cause a large amount of water loss in the human body, resulting in tight skin, dry mouth, chapped lips, and getting angry, but also cause respiratory diseases such as flu and pharyngitis.

Dry indoor air will also cause harm to furniture, floors, home appliances and other utensils, shortening the service life.

Even in the south, the indoor air humidity is only below 40%Rh in autumn and winter when there is no rain or after using the air conditioner, which is significantly lower than the normal humidity of 40%0%Rh in the room. It's just the right time to get rid of the dryness and enjoy the warm and humid autumn and winter from now on.

Fan's father and son are very optimistic about this household humidifier project.
