Chapter 101: Fishing Gear

At the end of the interview, the moderator mentioned the use of practicing martial arts, and Tagawa stated the main points in two articles he wrote in the Taijiquan Association the other day.

He said: "The ancients said that 'chivalry is forbidden by force', and there is a certain amount of truth. We practiced kung fu and practiced battles every day, and the idea of using force to solve problems naturally came to our minds. Those of us who practice kung fu should still be careful not to do it casually, otherwise trouble will inevitably follow. Don't always think about what is uneven, shovel the strong and help the weak, that's what the police should do. Whatever the reason, once you hurt someone, it is a very troublesome thing. Not to mention breaking the law and committing evil with the help of kung fu. In fact, the line between justifiable self-defense and intentional wounding is not so clear. ”

Li Tianlai: "You have been saying just now that you want to strengthen the exchanges between various martial arts schools and schools and encourage combat practice, what should you pay attention to for this kind of fighting?"

Tagawa: "What we encourage is measured sparring for the purpose of friendship and common improvement. Oppose the brave fighting because of the purpose of competing for strength and smashing the field. For example, at the opening ceremony of a boxing gym, any uninvited challenge, no matter how politely said, can be seen as smashing the arena and unfriendly behavior. In this case, the organizer often can't refuse for the sake of face, and has to do everything possible to win when he starts, and the shot will lack moderation, and it is easy to have an accident that hurts people. ”

"I wrote two articles a few days ago, entitled "On the Self-Defense of Martial Artists, Fighting Injustice, and Fighting Bravely", and "Talking about the Exchange between Martial Artists". In my opinion, the use of kung fu and human hands should not be encouraged in any case, and there are contradictions that can be resolved through legal means, and hitting people with hands will not play a positive role. ”

"When it comes to self-defense or fighting, in modern society, how many opportunities do you have to encounter irresolvable personal attacks? Most martial artists encounter such opportunities that arise under their indulgence or active stimulation. Strictly speaking, it is actually taking the initiative to make trouble, and of course it should not be promoted. ”

At the end of the interview, Tagawa specially communicated with Li Tianlai, hoping not to cut out the last paragraph about doing things with people. He believes that only effective restrictions on casual action can ensure the healthy development of this kind of combat competitive sports.

The day after the interview, Tian Chuan received Zhu Dacheng from Weihai in the capital. The advanced fishing rod winding production process developed by Professor Xingguo of the Navigation Continent has been completed, and Zhu Dacheng is here to accept this process this time.

The market for lighter and stronger high-grade fishing rods has always been dominated by Taiwanese companies, and mainland fishing gear manufacturers have never been able to set foot in it. One of the main differences lies in the control of strength uniformity and the control of fiber direction.

The name of the material science of FRP or carbon fishing rod is "polymer polymer-based glass fiber or carbon fiber reinforced composite", which is to arrange high-strength and low-density fiber materials according to certain rules, and then bond them together with glue.

This type of material is inhomogeneous, with high strength in the direction of the fiber and low strength in the direction perpendicular to the fiber. In the process of using the fishing rod, the direction of force is relatively fixed, if the fibers can be arranged along the direction of force, less fibers can be used to achieve the same effect, to achieve the purpose of weight reduction.

The winding process developed by Professor Lu is from this aspect to solve the problem of reducing the weight of fishing rods.

Accompanied by Tian Chuan, Zhu Dacheng met Professor Lu Xingguo in the Department of Materials of Hangda University. Professor Lu took the two of them to see the concept machine of winding molding.

This is a simple machine for demonstration and test, the main motor drives the core rod to rotate, and winds the impregnated fiber from the wiring machine to the core rod, and the wiring machine swings left and right when the core rod rotates, controls the winding angle of the fiber, and achieves the purpose of reasonably controlling the direction of the fiber. In front of the wiring machine, there is a strand machine composed of multiple spindles, which can combine multiple strands of fibers together, speed up the processing speed, and can mix different varieties of fibers to adjust the mechanical properties.

The whole machine is controlled by a computer, and the process parameters can be adjusted through software.

The speed of the machine is not too fast, and it takes about two or three minutes to wind a one-meter-long fishing rod. Tian Chuan and Zhu Dacheng are very satisfied with this machine, the machine is not complicated, the key lies in the calculation formula of strength and the control program of the computer. If you need to increase the output, just increase the number of machines.

After watching the demonstration of the wrapping machine, Professor Lu took them to see the samples made. The sample is not painted, it is not pretty, and the whole is black, which Professor Lu said is the color of carbon fiber.

The thickest part of the knuckle of the 4.5-meter sample rod was only the thickness of a little finger, and Professor Lu was a little worried: it was too thin to grasp. Tagawa smiled: "Just add a thicker grip to the grip." ”

Tian Chuan and Zhu Dacheng checked the tonality and strength of the fishing rod, and found that this crucian carp rod is a three-seven tone, the whole is a little hard, and it can easily pick up a bottle of 500 grams of mineral water, and the weight of the fishing rod itself is less than 140 grams, which is one-third of the more popular FRP rod, which is much lighter than the high-grade carbon rod on the market, and it is as light as nothing in the hand. The advantages in competitive fishing will be very obvious.

Professor Lu said: "In fact, in terms of strength, it can be lighter, but the stiffness cannot be guaranteed. ”

Zhu Dacheng said: "It's light enough, and it doesn't mean much to be light." ”

Back at Professor Lu's office, Tian Chuan and Professor Lu signed an intellectual property transfer agreement on the spot. Because the issue of program control was not considered at first, Tian Chuan added 100,000 yuan to Professor Lu on the basis of the original development agreement as a software development fee.

At noon, Tian Chuan invited Professor Lu's development team and Zhu Dacheng to have a meal to celebrate the success of the project.

After the meal, Zhu Dacheng invited Tagawa to cooperate with him in the production of high-grade fishing rods, but Tagawa refused. Now the profits of fishing gear production are difficult to impress him, and he does not have much energy to devote to this. He even wanted to transfer his shares in the bait company if the right situation was right.

Hearing that Tian Chuan had the idea of transferring the shares of the bait company, Zhu Dacheng became interested. Now, due to the development of competitive fishing, the bait company is in a period of rapid growth, and it is obvious that it is an old hen that can lay golden eggs. So he asked Tagawa about his psychological price, and Tagawa said: "I can't make a reasonable offer for a while, and I need to wait for my team to evaluate before I can give it." Don't worry, if I have the idea of transferring, I will definitely contact you first. ”

According to the previous agreement, Tian Chuan transferred the fishing rod winding production process developed by Professor Lu to Zhu Dacheng at a price of 3.5 million yuan. As soon as he changed hands, he made two million yuan, and Tian Chuan was in a good mood, this money was enough for this trip to the United States, and there must be a surplus.

In the afternoon, he accompanied Zhu Dacheng to visit several acquaintances of the National Fishing Association, and after a meal of wine in the evening, Tian Chuan said goodbye to several friends of the Fishing Association the next day, returned to his hometown, and prepared to go to the United States.

Before Tian Chuan's car left the capital, he received a call from his uncle Tian Jianyu, who was in charge of the Shuanghe cotton experimental field, that there was an insect infestation in the cotton field, and it was a cotton bollworm. Now that the flood has just passed, the cotton field is high and has not suffered much damage, but it is the hottest time of the year, and the water vapor in the cotton field is evaporated by the hot sun, and the ground is as hot as a steamer. Workers have to wear strict protective clothing when applying medicine, and the heat is unbearable. Yesterday, after only a few injections, two workers suffered from heat stroke.

Tian Jianyu said that he had already notified the development center and Mr. An, and there was nothing he could do for the time being.

Tagawa asked him to stop taking the medicine first, safety first. He immediately turned and headed for the cotton fields.

In the cotton field, the pink flowers were blooming, and Tagawa saw in the field that a small number of fruits had been produced on the cotton plants, and the fruits were small, and many of the fruits had insect-eaten holes.

A few sprayers were placed on the ground, and the workers had already returned to their rooms, it was too hot outside.

Tian Jianyu came out and said to Tian Chuan: "It is too dangerous to apply medicine by hand, and the speed is too slow. It will take a long time for a few of us to spray so many cotton fields, and I am afraid that later, before the spray is finished, the cotton will be bitten by insects. ”

Tian Chuan looked at the rows of cotton, and suddenly thought of a spraying artifact that he had seen on the Internet in his previous life. With a long plastic tube, a downward facing spray nozzle is installed on top at regular intervals. One end of the plastic pipe is attached to the spraying pump on the tractor, and the spray is applied with the pump. In order to prevent the plastic pipe from sinking, a helium balloon is hung on the pipe every other section, and the plastic pipe is held up by the buoyancy of the balloon, and the tractor is driven to hit the cotton field dozens of meters wide at one time.

At this time, Lu Jun, who was in charge of the experimental field in the R&D center, and several other people also arrived. Tagawa told them what he thought, and everyone thought it was a good idea, so several people drew a sketch of the structure on the spot and sent people to purchase the items they needed.

In the afternoon of the same day, we assembled such a set of simple spraying devices, and conducted a trial, after adjustment, basically met the requirements of use. It's just that I didn't find helium for a while, so I had to replace it with hydrogen first. Hydrogen and helium are about the same density and can provide similar lift. It's just that hydrogen is very easy to burn and more dangerous. Whereas, helium is an inert gas and there is no danger.

An hour before dark, we completed the spraying operation of more than 20 acres of land in the first part. The spraying truck is controlled by three people, and more than 20 acres of spraying can be completed in one hour, and the efficiency is many times higher than that of manual spraying.
