What at is is th the all all-Jap apan an man manufac factu turin ring scene gre reat at war? war? ■What is the scene great war?

It is a rally (bringing together the scene that small and medium manufacturers in the whole country are bet the boast of its company and made, and the fight by the one to one). Manufacturing seriously designs a small scene, and everything is poured and the technology that its company can have with a professional machine is made. A professional technique is fatty soaked of the ring

• n each other.

■What rule?

• Having kept turning longer than other party's

scene wins. ?It is defeated besides the ring when going out. ?Game end at two successive victories ?The victor can get loser's scene. (It is a content total removing of booty till then. )

Center of gravity rises in the angle of bank though the make a careless pitch by the axis blur when largeness turns it on is few. 【 contradiction problem 】 5. The frictional drag grows by causing friction with the ring, and the scene heavy as for the Scene point. Is a method frictional drag a little even if it is heavy? 【 contradiction problem 】 6. Let's devise the method of improving the rotational speed of the scene. Besides, does the resource that can be used :? 7. The method of absorbing only rotation energy of other party scene? 8.

A lot of design parameters are taken up at a time. It allocates to the orthogonalization table, it experiments, and it evaluates it. To evaluate the noise-proof, noises such as the civil war and turbulence (error margin factor) are included in the experiment. The noise-proof of the function of the system is evaluated. Signal-Noise ratio (ratio of signal/noise) is used as a standard.
