Title: Fuel injection valve
Inventor: AKIYAMA TAKANORI
IPC: F02M61/18
Filed: 1992-03-09
Abstract: PURPOSE:To promote atomization of fuel spray infected, to shorten delay in ignition, and to provide combustion at a low pressure rising rate by providing a plurality of hole nozzles opened from an annular fuel path to the surface of the front end part. CONSTITUTION:When a fuel of high pressure fed from a fuel pump 3 reaches a fuel reservoir 5 through a fuel path 4 provided on a nozzle main body 1, a needle valve 2 is pushed upward and is opened by the fuel pressure against the force of a spring 6 by which the needle valve 2 is pressed down, and the fuel flows into a capped hole 7 from the fuel reservoir 5 through a valve seat 12, and passes an annular fuel path 11 in a front end part 9 of the nozzle main body 1 through an oil transfer hole 10, and the fuel is injected from a plurality of hole nozzles 8 provided on the front end part 9 of the nozzle main body 1. After the fuel injection, since the pressure of the fuel of the fuel reservoir 5 of the nozzle main body 1 is reduced, the needle valve 2 is closed downward by the force of the spring 6 into close contact with the valve seat 12, and feeding of the fuel is thus stopped.

Title: Preparation of plate shaped catalyst
Inventor: ICHIKI MASAYOSHI
IPC: B01J35/02
Filed: 1985-03-13
Abstract: PURPOSE:To prepare a plate shaped catalyst having a uniform thickness by reducing the flowability of a slurry, by immersing a metal net in the slurry received in a tank and drying the slurry film under heating simultaneously with the drawing-up of said metal net. CONSTITUTION:For example, a pair of left and right infrared heaters 3, 4 are arranged in opposed relationship above the liquid level of the slurry 1 in a tank. The slurry is prepared by kneading a powdery carrier and/or a powdery catalytic component with a binder and, at the same time when the metal net 5 immersed in the slurry 1 is drawn up from the slurry 1, the slurry films 6 on the surfaces of the metal net are heated by the heaters 3, 4 to remove the flowability of the slurry film 6 through the loss of a slight amount of moisture without raising said slurry film to high temp. In this case, because the range up to the upper ends of the heaters 3, 4 comes to the concn. amount of the flow-down slurry to the lower end of the metal net 5 from a moment when the lower end of said metal net 5 was separated from the liquid surface of the slurry, said concn. amount can be reduced to a large extent.
