Title: Semiconductor light-emitting device
Inventor: ITO AKIRA
IPC: H01S5/00
Filed: 1988-03-24
Abstract: PURPOSE:To obtain the GaInPAs light-emitting element using a GaP substrate by a method wherein the multilayer, provided on the strained superlattice located on the GaP substrate, is composed of a GaInPAs active layer, an AlGaInP- clad layer containing Al or a GaInP-clad layer containing no Al. CONSTITUTION:A strained superlattice layer is formed on a GaP substrate 1, and a multilayer having a double heterojunction, namely, an AlGaInP clad layer 3, a GaInPAs active layer 4 and an AlGaInP clad layer 5, are epitaxially grown successively from the top of the strained superlattice layer 2. As the GaInPAs active layer 4 is grown on the GaP substrate 1 in this structure, this growth can be made by providing the strained superlattice layer 2 on the GaP substrate 1. As the GaP substrate 1 and the strained superlattice layer 2, which is made of a wide bandgap material, are transparent to the radient light coming from the GaInPAs active layer 4, and also as the GaP substrate 1 has a high thermal conductivity and an excellent heat-radiating property, there is no limitation in the picking-out direction of the emitted light when an element is formed, and as a result, the designing to the element is free.

Title: Oil pressure generating device
Inventor: MIYAYASHIKI HIDEAKI
IPC: F04B49/08
Filed: 1982-04-30
Abstract: PURPOSE:To maintain the minimum oil pressure at the time of automatic starting at a high level by starting an emergency oil pump, when the oil pressure has lowered violently, early through the action of an oil pressure drop speed sensor. CONSTITUTION:Each of the lines for control oils 3a, 3b, 3c, a bearing oil 6 and a suction supply oil 10 is equipped with a pressure switch 13a-13d and a pressure drop speed sensor 14a-14d. When the speed of drop of the line oil pressure has exceeded a certain specified value, the pressure drop speed sensors 14a-14d will sense it to actuate starting of a backup motor-operated oil pump. Accordingly if the line oil pressure drops violently, this backup pump will start to commence oil supply. Thereby the minimum oil pressure point 29 will become higher than the one 25, and thus the reliability for operation and maintenance of the steam turbine is enhanced.
