Title: Fuzzy controller capable of change of rule and its working method
Inventor: NISHIDAI HAJIME
IPC: G05B7/02
Filed: 1989-08-31
Abstract: PURPOSE:To realize the smooth change of the fuzzy control output by decreasing gradually the rate of the fuzzy inference output set right before the change of a rule as the time elapses from the rule changing time point and at the same time increasing gradually said rate set after the change of the rule. CONSTITUTION:The fuzzy control output set right before the change of a rule and held by a sampling/holding circuit 13 is given to a coefficient multiplier 21 together with the fuzzy inference output of a fuzzy control circuit 10 given to a coefficient multiplier 22 respectively. The multiplier 21 outputs the fuzzy inference output set right after the rule change after multiplying it by a coefficient alpha. Meanwhile the multiplier 22 outputs the fuzzy inference output set after the rule change after multiplying it by (1 - alpha). The outputs of both multipliers 21 and 22 are given to an adder 25 and added together. These added outputs are outputted as the fuzzy control output. The coefficient alpha reduces monotonously as the time elapses and therefore the rate of the fuzzy inference output set right before the rule change decreases gradually against the control output received from an output switch circuit 20. At the same time, the rate of the fuzzy output increases gradually after the rule change. As a result, the control output value changes smoothly.

Title: Optical material and its production
Inventor: ISHIWATARI YASUHIKO
IPC: G02F1/35
Filed: 1990-08-28
Abstract: PURPOSE:To obtain superior chemical stability by forming a metal oxide film as an insulating layer, obtaining the metal oxide film by forming a metallic film on a semiconductor nucleouses and then oxidizing it, and obtaining the metallic film by decomposing and depositing gas containing metal on the semiconductor. CONSTITUTION:The insulating film is the metal oxide film, which is formed by forming the metallic film on the semiconductor nucleouses and oxidizing it; and the metallic film is deposited on the semiconductor by decomposing the gas containing the metal. Namely, a semiconductor material is not embedded in a matrix, but collected after each being coated with a material as a matrix agent. Therefore, the packing rate is essentially higher than that of an optical member obtained by simply dispersing semiconductor superfine particles in the matrix material and higher conversion efficiency is obtained. Consequently, the optical material which has superior chemical stability as a coated particulate assembly is obtained.

Title: Method for reforming sludge
Inventor: SUGAYA KENZO
IPC: C02F11/12
Filed: 1996-08-06
Abstract: PROBLEM TO BE SOLVED: To destroy and peel the high-viscosity org. materials coating particle surfaces and to improve subsequent dehydration performance by treating raw sludge with a planetary ball mill having rotating and revolving mechanisms at the time of pretreating the sewer sludge and night soil sludge when the sludge is subjected to separation of solid from the liquid by using a dehydrating machine. SOLUTION: The sludge, and sewage, such as night soil, is treated by using the planetary ball mill which executes high-speed rotation and revolution motion slightly lower than this rotating speed at the time of subjecting the sludge to the sepn. of the solid from the liquid by using the dehydrating machine. The polluted particles charged into the planetary ball mill are repetitively subjected to impact and frictional crushing effect, by which the high-viscosity org. materials coating the particle surfaces are destroyed and peeled. When the sludge subjected to such effect is taken outside the working system, the mol.wt. of the water adsorbed in the particles decreased in the electric charge quantity decreases and the particles are flocculated by the force acting between each, by which the larger reflocculated flocs are formed. The subsequent dehydration property is thus improved.
