Inventor: HIROTA TOSHIO
IPC: F02M27/02
Filed: 1983-01-24
Abstract: PURPOSE:In an alcohol fuel engine, to prevent occurrence of insufficient control negative pressure by operating a reciprocal pump through reformed gas pressure to produce negative pressure and functioning a negative pressure actuator through a surge tank. CONSTITUTION:An exhaust bypass valve 6 for regulating exhaust gas flow to a reformer 1 is controlled by a negative pressure actuator 8 through a solenoid valve 19 to be functioned by a command from a controller 21 by the negative pressure of an intake manifold 14 through a negative pressure regulator 16. Under low speed, intermediate load continuous operation, when the control negative pressure of a surge tank 22 drops below setting level, the controller 21 will turn on-off a three-way solenoid valve 34 through a signal from a pressure sensor 23 while to function a reciprocal pump 30 through the reformed gas pressure from a feed pipe 36 thus to drop the pressure in the surge tank 22. Consequently the control negative pressure of negative pressure actuator 8 will never be insufficient, to control the exhaust bypass valve reliably from full-open to full-close under all operational conditions.

Title: Resin composition for photoresist
Inventor: ASANUMA TADASHI
IPC: G03F7/038
Filed: 1985-01-21
Abstract: PURPOSE:To provide satisfactory functions such as high sensitivity and resolving power to a resin composition by irradiating the rays of light on the resin composition having a specified composition. CONSTITUTION:The resin composition for a photoresist is composed of a diisopropenylbenzene copolymer soluble in a solvent and contg. diisopropenylbenzene units by at least 1% of the amount of the copolymer and dicyanobenzene and/or tricyanobenzene. It is necessary that >=1% of the monomeric units in the copolymer is diisopropenylbenzene. When a diisopropenylbenzene-alpha-methylstyrene copolymer is used, the resulting resin composition made insoluble by a cross-linking reaction is perfectly decomposed by heating to 300-400 deg.C, so the copolymer is preferably used as the component of a photoresist. Since the resin composition is made insoluble in a solvent and the insoluble composition is decomposed and volatilized at such a relatively low temp., the resin composition is suitable for use as a photoresist.
