Title: Quantitative plunger pump
Inventor: KAWASAKI TAKUYA
IPC: F04B53/10
Filed: 1986-12-26
Abstract: PURPOSE:To prevent a liquid from stagnating in the middle of a line by sucking the liquid through a plunger for extrusion of a proscribed quantity and providing a suction valve in the plunger. CONSTITUTION:When a suction valve 3 is opened by a cylinder 5 and a plunger 2 is lifted to the fixed height by a cylinder 10, a liquid L is fed from a storage tank 7 through a liquid inlet pipe 6, the suction valve 3, and a liquid passage 4 by the quantity that the plunger 2 is moved because a discharge valve 9 is closed. Next, when the suction valve 3 is closed and the plunger 2 is lowered by the cylinder 10, the liquid L is pushed out from a discharge port 11 through the discharge valve 9 by the quantity of this stroke. Accordingly, the liquid L invariably flows only in one direction, and the liquid line rarely has positions where the liquid stagnates.

Title: Manufacture of semiconductor integrated light source
Inventor: ASANO HIDEKI
IPC: H01S5/00
Filed: 1990-11-15
Abstract: PURPOSE:To manufacture, with good reproducibility and stably, a light source in which a phase-shift DFB laser oscillated at a high yield and in a monoaxial mode and a light modulator have been integrated by a method wherein a diffraction grating is flattened by growing, thermally deteriorating and etching an InP layer. CONSTITUTION:A phase-shift type diffraction grating 9 is formed on the whole surface of an n-InP substrate 1; after that, an n-InGaAs guide layer 2, an InGaAsP active layer 3 and a p-InP clad layer 4 are grown continuously on the whole surface. In succession, the layer 4, the layer 3 and the layer 2 are sequentially etched selectively by making use of an SiO2 film 5 as a mask. An n-InP layer 6 is grown on the diffraction grating which has been revealed by this etching operation and the diffraction grating is flattened. When a light modulator part is buried and grown selectively, the diffraction grating is deteriorated thermally and flattened. Alternatively, before the light modulator part is buried and grown selectively, InP is etched during a crystal growth process and the diffraction grating is flattened. Thereby, the diffraction grating can adopt a phase shift structure, the yield of a monoaxial-mode oscillation of a DFB laser is increased and the production yield of an element can be enhanced.

Title: Manufacture of mesfet
Inventor: MATSUE SHUICHI
IPC: H01L29/812
Filed: 1986-12-24
Abstract: PURPOSE:To contrive high speed operations and high integration by forming a metal film on an N-type impurity layer of the gallium arsenic substrate surface and then by etching a resist film after forming it on the surface of the metal film, thereby forming a gate electrode on sidewalls below the resist film and also by forming source and drain electrode on both sides of the electrode with the vaporization to the surface of the N-type impurity layer. CONSTITUTION:An N-type impurity layer 2 is formed on the substrate surface 1 by ion- implanting silicon atoms into a gallium arsenic substrate 1. And a metal film having a high melting point is formed by spattering metals having a high melting point such as Ti/W over the N-type impurity layer surface 2 after annealing its N-type impurity layer 2. After that, a resist film 3 is formed at the prescribed part of its metal film surface having the high melting point. And then, a gate electrode 10 is formed by performing isotropic etching treatment of the metal film having the high melting point by using the resist film 3 as a mask. The lateral etching amount of the gate electrode 10 is adjusted by the intensity of etching. The utilization of resist film 3 as the mask allows AuGe/Ni/Au to be attached to the N-type impurity layer surface 2 by vaporization and the gate electrode to self-consistently form source and drain electrodes 7 and 8. Further, an AuGe/Ni/Au film 11 is formed even on the resist film surface 3. After that, the unnecessary film 11 and resist film 3 are removed and a sinter process is carried out for the gate electrode 10 as well as the source and drain electrodes 7 and 8.

Abstract: PURPOSE:To prevent the generation of dust and the adhesion of a foreign manner, to keep a semiconductor device clean and to smooth the stepped section of the whole surface of a metallic layer by injecting the solidified particulates of a substance, which is easily solidified and liquefied or solidified and vaporized and does not contaminate the semiconductor device, onto the surface of the metallic layer together with a carrier gas. CONSTITUTION:A carrier gas 5 containing solidified particulates 4 is ejected and injected toward a metallic layer 1 from a nozzle 6 while repeatedly parallel- displacing the metallic layer 1 with a stepped section 1a. When the solidified particulates are made to collide with the metallic layer such as an aluminum layer in general, the metallic layer can be deformed plastically. Accordingly, a large number of such solidified particulates 4 in grain size allowble in the surface of the metallic layer 1 finally are carried by the gas 5 at a flow rate capable of plastically deforming the metallic layer 1 by collisions, and injected and made to collide to the metallic layer 1, thus smoothing the metallic layer on the side wall of the stepped section 1a by the neighboring metallic layer 1.

Title: Controller for inverter

IPC: H02P27/06
Filed: 1991-11-26
Abstract: PURPOSE:To control a speed without tripping an overcurrent of an induction motor (DM) during its reverse rotation by detecting a rotating speed and a rotating direction from a residual voltage of the motor. CONSTITUTION:When an induction motor (DM) 2 starts to rotate, a rotating speed detector 4 calculates the rotating speed of the DM 2 according to a residual voltage detected by a residual voltage detecting transformer 3, and a rotating direction detector 18 detects a rotating speed of the DM 2. If the DM 2 now makes a reverse rotation, an inverter 1 outputs a frequency to meet the speed of the DM 2. A phase sequence of the output frequency at that time is reverse, the output voltage is initially '0' and gradually increased to a voltage to meet the output frequency. And, the speed is decelerated to '0', and then accelerated to a command value based on a command signal of a necessary speed. Then, if the DM 2 makes a normal rotation, the phase sequence of the output frequency is positive, the output voltage is initially '0', and gradually increased to a voltage to meet the output frequency. It is accelerated or decelerated to the command value based on the command signal of the necessary speed.
