Patent JP-S60103612-A (JP)
Title: Manufacture of semiconductor device
Inventor: OOURA JIYUNICHI
IPC: H01L21/26
Filed: 1983-11-11
Abstract: PURPOSE:To control and reduce the life time of minority carriers in a semiconductor and, at the same time, make slight damages in semiconductor devices by irradiating neutron rays having high kinetic energy exceeding a specific value on the semiconductor devices after completion of high temperature process such as diffusion of impurity atom and so forth. CONSTITUTION:Neutron rays having high kinetic energy exceeding 10keV are irradiated on semiconductor devices of which high temperature processes exceeding 400 deg.C have been completed, and the life time of minority carriers is controlled to reduce thereof in minor damage conditions. The reciprocal of the life time tau of minority carriers in a semiconductor varies in proportion to the number of recombination centers of carriers formed by irradiation of high speed neutron. Furthermore, a damage coefficient K of the life time of minotity carriers in a semiconductor caused by irradiation of radiant rays is proportional to energy of irradiating radiant rays. Accordingly, the damage coefficient K of the life time in the case of irradiation of 1MeV electron rays substantially coincides with that in the case of irradiation of 10keV neutron rays and, therefore, neutron rays have an effect superior to electron irradiation.

Title: Combustion apparatus for gas turbine engine
Inventor: PIITAA NIYUUTON
IPC: F23R3/28
Filed: 1992-08-07
Abstract: PURPOSE: To improve flame stability by arranging a louver and a dome shaped portion on a wall such that cooling air is exhausted substantially in the same direction. CONSTITUTION: Louvers 70, 72 are directed such that corresponding air jets 60, 58 are discharged in the direction of a dome section 4. Accordingly, the air jet 60 increases the shape of a spiral 68. In contrast, the air jet 58 discharged oppositely with respect to dome shaped air jets 62-66 expels a circulation flow from an internal surface of a liner 32 for stabilizing the spiral 68 adjacent to a dome shaped section 35. During operation of a gas turbine engine a fuel and air under reaction continuously mixes a hot combustion product with the fuel and air not reacted. Hereby, the fuel and air are circulated in the spiral 68 for stabilizing a combustion process. The hot product acts to ignite the fuel and air entering anew the combustion chamber. Thus, a stable reaction fire can be maintained in the combustor.
