Title: Silver halide emulsion, silver halide photographic sensitive material and treatment of this sensitive material
Inventor: TAIMA YASUO
IPC: G03C5/26
Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To obtain the silver halide photographic emulsion high in sensitivity and low in fog and high in the gamma value by adding fine silver halide grains subjected to reduction sensitization in the insides and/or the surfaces during and/or after formation of silver halide grains. SOLUTION: The fine silver halide grains subjected to reduction sensitization in their insides and/or their surfaces are added during and/or after formation of the silver halide grains of the emulsion at the time of preparation of the photographic emulsion. The silver halide emulsion is sensitized by using a selenium compound or a tellurium compound. The fine silver halide grains can be obtained, for example, by subjecting them to reduction sensitization with a reduction sensitizing agent, such as, stannous salts, amines or polyamines, while adding water-soluble silver salts and water-soluble alkali halides to form silver halide grains.

Title: Exhaust gas weight reducing method for diesel engine
Inventor: EGUCHI NOBUJI
IPC: F02B3/06
Filed: 1989-12-07
Abstract: PURPOSE:To reduce the weight of exhaust gas at time of low load as well as to abate the quantity of harmful ingredients in the exhaust gas by heating intake air in an inlet system and lowering the density of this intake air at time of engine low load, while decreasing the weight of the intake air being charged into a combustion chamber. CONSTITUTION:At time of low load in a diesel engine 10 inclusive of idling time, opening of a solenoid flow valve 42 is increased by an electronic controller 44, and a quantity of pressurized air being guided to an air cylinder 36 by way of a pressurized air passage 38 is increased as well. With this increment, opening of a butterfly valve 34 increases, thereby increasing the quantity of exhaust gas flowing toward an intake passage 30. Intake air in an intake branch pipe 16 is heated by this increased exhaust gas at a heating box 28, expanding the intake air, and the density is reduced. In consequence, the weight of air charged in a combustion chamber of the engine body 12 is reduced, setting it down to a proper quantity, thus exhaust gas emitted out of the combustion chamber and the weight of harmful ingredients in the exhaust gas are all reduced.
