Title: Fuel injection device
Inventor: HIGAMI KAZUMASA
IPC: F02M69/00
Filed: 1990-06-14
Abstract: PURPOSE:To accelerate the atomization of injected fuel so as to improve startability under low temperature and stabilize combustion by accommodating a part of supercharging assist air discharged from an air pump into a reservoir, and feeding this supercharging assist air toward injected fuel at the starting time of an engine. CONSTITUTION:During the operation of an engine body 1, a part of supercharging assist air is accommodated into the pressurizing chamber 32 of a reservoir 31, and a switching valve 36 is closed at the stop time of the engine body 1 so as to hold air pressure in the pressurizing chamber 32 to the set pressure. At the restarting time of the engine body 1, the switching valve 36 is opened promptly before the supercharging assist air from an air pump 19 is boosted so as to feed the supercharging assist air from the pressurizing chamber 32 toward the air chamber of an injection valve 10. The injected fuel is thereby atomized at the starting time of the engine body 1. At this time, the pressurizing chamber 32 is partitioned in the reservoir 31 by a piston 33, and the piston 33 is energized constantly downward by the spring 34. The generation of pulsation and the like to the supercharging assist air is thereby prevented effectively.

IPC: D21H17/62
Filed: 1995-05-31
Abstract: PURPOSE: To obtain an electrophotographic transfer paper which has excellent cuttability and sliding characteristic to obviate such co-delivery as to induce overlap feed trouble and is imparted a sufficient sizing property by specifying the components to be incorporated therein. CONSTITUTION: This transfer paper is neutral paper consisting essentially of kaolin and contg. fillers used in combination with talc, neutral rosin-based sizing agents and size fixers.

The hardness is, therefore, lower than the hardness of the fillers to be generally filled in the neutral paper, such as calcium carbonate and consequently, the wear resistance of a cutting blade by the fillers is improved. Since the period of exchanging the cutting blade or repolishing is extended, the paper having the decreased burrs of the cut surface as compared with the paper filled with the calcium carbonate is obtd. The paper having the excellent cuttability, a high coefft. of friction and excellent slipping characteristic is obtd.
