Title: Open/close control method of irrigation valve
Inventor: KAWAMURA YOSHIKI
IPC: A01G25/16
Filed: 1985-02-23
Abstract: PURPOSE:To facilitate remote control of irrigation valve without employing special controlling fluid or power by utilizing the hydraulic pressure of irrigation water for open/close control of valve. CONSTITUTION:The irrigation water is blocked at the take-in port 14 by means of a diaphragm 10 and a portion of the irrigation water is within the pressure chamber 20 under closed condition of solenoid valve 25. Here, the pressure in the pressure chamber 20 is prevailing with respect to the relationship of forces which are applied onto both sides of diaphragm 10, which will choke the intake port 14. Upon opening of the solenoid valve 25, the water in the pressure chamber 25 is discharged to release the pressure in the pressure cham ber 20 thereby the irrigation water to be fed continuously through the pressure supply hole 16 will pass through the pressure discharge hole to the head of the solenoid valve 25. Consequently, only the hydraulic pressure at the take-in port 14 will function onto the diaphragm 10 thus to discharge the water in the water path through the discharge port 15.

Title: Zinc oxide varistor, manufacture thereof, and crystalline glass composition for coating
Inventor: KATSUMATA MASAAKI
IPC: C03C8/00
Filed: 1990-02-15
Abstract: PURPOSE:To provide a reliable zinc oxide varistor with long operation life by applying high-resistance layers on sides of a sintered body containing a main component of zinc oxide. CONSTITUTION:A sintered body 1 consisting mainly of zinc oxide is prepared, which itself has varistor characteristics. The sintered body 1 is provided with high-resistance layers 3, on its sides, which are formed of crystalline glass that includes a main component of PbO containing 0.5-5.0% nickel oxide in terms of NiO. The main component of crystalline glass is PbO, and thus its crystallization is promoted by the addition of NiO. The strength of the glass coating is improved by adding SiO2. Since the coating makes close contact with the sintered body, it has high resistance to discharge. In addition, it has high electrical resistance so that the degradation of voltage dependency is mini mized during baking. Therefore, it is possible to provide a reliable zinc oxide varistor with long operation life.

Title: Controller of manipulator
Inventor: KOMATSU OSAMU
IPC: B25J9/16
Filed: 1988-02-19
Abstract: PURPOSE:To enable force control to be carried out without any stationary deviation by adding an external signal to the output signal of a proportion control means to produce the input signal of a drive means. CONSTITUTION:When target torque Tm representing a target signal and joint torque Ts representing an external signal are given, a value of drive torque required for generating the target torque Tm is calculated through a proportional adjuster 1. The pattern of this drive torque value is given in such a way that its initial value becomes larger as a difference between the target torque Tm and the joint torque Ts increases and said torque value becomes smaller as it approaches the target torque Tm and becomes zero when it reaches the target torque Tm. On the other hand, the joint torque Ts is also inputted in an adder 2 to be added to a signal from the proportional adjuster 1 and the output therefrom is inputted in a servo driver 3. Therefore, even though a deviation between the target torque Tm and the joint torque Ts becomes zero, the joint torque Ts is continuously inputted in the servo driver 3. As a result, an arm mechanism 5 can continuously maintain the target torque Tm even if it is subjected to reaction from a working body.
