Title: Flow control valve
Inventor: NISHIDA KOUYOU
IPC: B62D5/08
Filed: 1983-03-24
Abstract: PURPOSE:To achieve a flow characteristic which will never fluctuate due to load variation by providing a variable orifice for limiting flow to hydraulic machineries as the differential pressure across a fixed orifice increases. CONSTITUTION:Upon steering operation, pressure increase in a power steering system due to load increase will cause minimization of differential pressure across a variable orifice valve 15. A spool valve 14 is moved by a spring 25 to the right to reduce the opening area of a return path 12 thus to increase flow through a delivery port 11 of pump to a feed path 13 of power steering system. A variable orifice valve 15 for determining flow to the power steering system is provided and controlled by the differential pressure across a fixed orifice 22 or the variation of pump delivery irrespective of the motion of spool valve 14. Consequently flow will never vary even if the pressure in the power steering system is increased.

Abstract: PURPOSE:To lower the threshold current of a modulation doping quantum well semiconductor laser by reducing the conduction-side band offset quantity of a light-emitting layer and a doping layer and making the first quantum level of the quantum well layer lower than the bottom of a conduction band. CONSTITUTION:A barrier layer 1B is made non-dope and a light-emitting layer 1WL, is constituted of a well layer 1W and a doping layer 1WL, so as to hold the light-emitting layer 1WD between the doping layers 1WD.
