Inventor: FURUSAWA HIROKO
IPC: G03G21/00
Filed: 1994-10-18
Abstract: PURPOSE: To maintain the cleaning effect for a photoreceptor even when the printing density in the initial stage is low, by using vinyl polymer fine resin particulates having a specified range of primary particle size and preparing the particles in a specified aggregated state. CONSTITUTION: The resin particulates are prepared to have 0.1 to 0.5μm average primary particle size and to contain 5 to 90vol% aggregated particles having 0.5 to 30μm size in the whole particles. As for the resin particulates, generally, vinyl org. fine particulates are preferably used because these particulates can be easily produced by a method such as emulsion polymn. and suspension polymn. Especially as the most preferably material, vinyl halides such as vinylidene fluoride or copolymer of styrene and acrylates or methacrylates esters are used. As for the polymn. initiator necessary to synthesize resin particulates, peroxide such as benzoyl peroxide or azo polymn. initiator such as azobis isobutylonitrile can be used.

CONSTITUTION:In a steady operation of a heat exchanger, where the pressure in a system line is not higher than the atmospheric pressure, when stagnation of a non-condensable gas in a condenser 2 is detected by a temperature sensor 17 fitted to the condenser 2, a heat-transmitting medium is fed into the system line by opening a suction port 11, a discharge valve 12 and a valve 4 and starting a feeding pump 6. While filling the system line, the heat-transmitting medium is sequentially raised in level, and raises the pressure in the system line. When a compound gauge 18 provided at a stagnating part for the non-condensable gas comes to indicates a pressure not lower than the atmospheric pressure, a blow-off valve 7 is opened, and hydrogen is released into the atmosphere through an atmospheric escape pipe 9 provided at a gas-liquid separator 8.

Abstract: PURPOSE:To miniaturize an apparatus by connecting a superconducting coil having a critical current value more than the current-limiting value of a circuit and a non-inductive superconducting switch having a critical current value lower than said current-limiting value and higher than a normal current in parallel with each other. CONSTITUTION:Between a power supply 1 and a load 5, a breaker 2 and a current-limiting device 3 are connected in series together with a line impedance 4. To form said current limiter 3, a reactor 3a of superconducting material having a critical current value more than a current value allowable for a line and a non-inductive switch 3b composed of superconducting material having a critical current value higher than a normal current value and lower than said allowable current are connected in parallel with each other. A normal current flows through said switch 3b, but, in case of an overload, the switch 3b opens to commutate a load current to said reactor 3a to limit said current. When the electric current further increases, however, the reactor 3a is also quenched and becomes higher in resistance to limit said current. Thus, an overload current is suppressed by a simple circuit.
