IPC: B29C41/34
Filed: 1981-10-29
Abstract: PURPOSE:To make it possible to form on an article in a simple manner the titled film which has both a slide proof effect and an ornametal effect by a  method wherein a vinyl chloride resin zoliscoated on the desired part of a basic article, then, after gelatinizing only the surface layer of that part by heating  with a gas flame, a plasticizing agent is deposited in layer over the coated surface and finally, the entire coated surface is gelatinized. CONSTITUTION:The film of a plastizol or an organozol of vinyl chloride resin is formed on the surface of a cloth product such as a pair of gloves, a bag or the like mainly made of a knitted fabric or a woven fabric by dipping, coating or pouring. After that, the coated product is subjected to a gas flame or a high temperature gas equal in power to the gas flame for several seconds until only the surface layer is gelatinized and the heating is interrupted before the lower layer of the coating is gelatinized. Then the plasticizing agent or a diluted zol is deposited in layer on the desired part of the surface of the product and the surface of that part is completely gelatinized up to the lower layer at the normal gelatinizing temperature of 200-250 deg.C to thereby obtain the target product.

Filed: 1989-07-07
Abstract: PURPOSE:To effectively take electroluminescence outside of a light emitting element so as to improve the element in light emitting efficiency by a method wherein at least one of the opposed electrodes of a MIS type semiconductor light emitting element is made transparent. CONSTITUTION:An N-type ZnSe low resistive film 2, a non-doped ZnSe high resistive insulating film 3, and a metal Schottky electrode 4 are laminated on an N-type GaAs crystal substrate 1, and a metal ohmic electrode 5 is provided onto the other side of the substrate 1 to constitute a MIS type semiconductor light emitting element.

Title: Control method for compressor
Inventor: BAN TAKASHI
IPC: F04B49/02
Filed: 1985-08-08
Abstract: PURPOSE:To enable decrease of a compression load and production of impact during the running state of a vehicle, when a detecting temperature is decreased to a set temperature, simultaneously with outputting of a closing instruction signal for an electronic expansion valve to the control circuit of the expansion valve, a clutch OFF signal is outputted through a delay circuit. CONSTITUTION:A computing circuit is a CPU 12 performs computation, and when a detecting temperature T is decreased to a set temperature T0, a closing instruction signal for an electronic expansion valve 8 is outputted to a control circuit 27 of the valve 8, and the valve 8 is held about at a closed state. Simultaneously, a clutch OFF signal, delayed by a time (t) in which the signal passes a delay circuit 25 compared with the opening of the valve 8, is outputted through the delay circuit 25 by the CPU 21. Thereby, after the valve 8 is closed, a clutch 2 is brought into an OFF- state after the time (t) lapsed, and a compressor 1 is brought into a stop. This, during the time (t), a liquid coolant within a vaporizer 10 is sucked out through a cooling load and suction motion of the compressor 1, and only lean gas coolant remains within the vaporizer 10. This, since lean gas is sucked during the starting, decreases a compression load, and reduces the production of an impact during the running state of a vehicle.
