Title: High pressure treating device
Inventor: HAYAFUJI TAKANORI
IPC: H01L21/22
Filed: 1979-06-29
Abstract: PURPOSE:To eliminate the need for taking notice of a heat resisting property of a pressure resisting vessel and simplify the structure of a furnace by a method wherein only a body to be treated in the pressure resisting vessel is heated. CONSTITUTION:A device is formed in such a manner that a semiconductor wafer 22 to be treated is housed in a high pressure vessel 21, on whose upper surface a transparent peep window 20 is attached, and laser beams 30 are irradiated only to the wafer 22 from the outside through the peep window 20.

Abstract: PROBLEM TO BE SOLVED: To reduce sticking of fuel to the wall surface of a combustion chamber by providing a fuel injection valve having a nozzle opening part and an ignition plug within a combustion chamber and providing the fuel injection valve so that fuel spray of different average speed may be formed. SOLUTION: Spray 3 is injected from a fuel injection valve 1 toward a cavity 6 of a piston 7 during an engine operation and a fuel injection time is a time when spray 3 is stored in the cavity 6. Spray 3 which collides against the cavity 6 evaporates, forms feel vapor and makes combustible air-fuel mixture near an ignition plug 2, mixing fuel vapor with air. At this time, the fuel injection valve 1 forms spray which is large in speed at the former half of the fuel injection time, subsequently controls to form spray which is small in speed and supplies air-feel mixture formed by spray which is large in speed to the vicinity of the ignition plug 2. A control to perform an ignition is performed when the air-fuel mixture is supplied to the vicinity of the ignition plug 2. Thus, stabilization of combustion and prevention of generation of soot are made compatible.
