Title: Method of vapor growth of high-resistance algaas mixed crystal
Inventor: KUNIHARA KENJI
IPC: H01L21/205
Filed: 1988-04-12
Abstract: PURPOSE:To perform oxygen doping with high reproducibility without contaminating a piping system of an apparatus by using organic metal alkoxyde containing any one of Al, Ga and As as an oxygen source. CONSTITUTION:As an oxygen source for doping AlGaAs mixed crystal, organic metal alkoxyde such as methoxyaluminum [AlO(CH3)3], methoxygallium [GaO(CH3)3] or trimethoxyaluminum [Al(OCH3)3] is used. An MOCVD apparatus to be used therefore is equipped with a methoxyaluminum vessel 19 and a flow adjuster 20 instead of an oxygen gas cylinder and its flow adjuster which used to be used. Since oxygen atoms contained in molecules in this organic metal alkoxyde are stable in a molecule, they do not contaminate the apparatus, are fed to a reaction pipe in a stable state, and thermally decomposed in the vicinity of a heated surface of a substrate. Then they are taken into a growing film of AlGaAs mixed crystal at a constant ratio together with Al, Ga and As decomposed from the material.

Title: Satellite signal reception amplifier
IPC: H03G3/30
Filed: 1992-03-13
Abstract: PURPOSE:To allow the amplifier to output and to utilize a signal whose noise level is a prescribed level or below even when an input satellite signal level is low by opening an output side switch when a noise level extracted from an output of an AGC amplifier is a prescribed level or over and closing the switch when the noise level is a prescribed level or below. CONSTITUTION:An input satellite signal A is subject to AGC control by AGC amplifier, control IF amplifier circuit 3, 4,1 2 and a BPF 12 or the like and a CS-IF signal D is outputted via a post-stage amplifier 15 and a switch means 21. A noise extract means 22 extracts noise from a signal at a level fluctuation detection point 8, a discrimination means 25 discriminates whether or not the level of extracted noise exceeds a prescribed level to switch the means 21 accordingly. Thus, when the signal A is at a normal level, the output reaches a prescribed level and when the noise level is large, the output is interrupted to prevent adverse effect onto the post-stage. Thus, even when the signal A is lower than the normal signal, the signal A whose noise level is a prescribed level or below is outputted and used.

Title: Optical star type communication equipment
Inventor: MIBU TAKAHIKO
IPC: H04L12/44
Filed: 1989-04-10
Abstract: PURPOSE:To eliminate the need for the addition of a preamble signal to a transmission data and to improve the data transmission efficiency by providing a sole timing reference, supplying the signals of timing reference to all stations and allowing each station to transmit/receive the data mutually according to the timing reference. CONSTITUTION:A timing signal generated by an oscillator 6 is converted into an optical signal by an optical transmitter 7 and transmitted to all optical receivers 9 via a star coupler 8. Each receiver 9 regenerates the original timing signal from the received optical signal and supplies it to a station 2. Thus, each station 2 uses the timing signal fed from the receiver 9 and is operated according to the same timing signal. Thus, the data is sent without adding a preamble signal to the data signal, thereby improving the data transmission efficiency.

Abstract: PURPOSE:To smooth a cathode electrode reaction by a method wherein a dispersed solution or a paste containing lithium nickel oxide powder is uniformly distributed on the surface of a porous nickel sintered plate and lithium nickel oxide is filled up into the sintered plate by vacuum suction from the back side of the sintered plate. CONSTITUTION:A dispersed solution or a paste containing lithium nickel oxide powder is uniformly distributed on the surface of a porous nickel sintered plate and at the same time the lithium nickel oxide powder is filled up into the sintered plate by vacuum suction from the back side to form a cathode. Thereby the mechanical strength of the cathode is improved and on the cathode surface side where there is much fillers, pores of comparatively small diameters are produced and on the back side where there is not much fillers, pores of comparatively large diameters are produced. By making the cathode surface side abut on an electrolytic solution and making the back side abut on a oxidizer gas, three-phase band reaction area is secured and gas diffusion is improved, thus the cathode electrode reaction is made smooth.

IPC: H02P7/292
Filed: 1983-05-24
Abstract: PURPOSE:To improve the response of a DC motor when a load torque abruptly varies by calculating the initial value of integrating means on the basis of a load torque presumed value and a speed deviation after variation when the load torque abruptly varies. CONSTITUTION:A speed controller 6 proportionally integrates a deviation between a speed command value wr and a rotating speed (w) and outputs a current command Ia. A current controller 7 proportionally integrates a deviation between the command Ia and a current I, and applies a control signal to a phase shifter 9 which controls the phases of thyristors in thyristor blocks 1, 2. An arithmetic circuit 21 inputs the speed (w), the command Ia and the speed deviation, and calculates the initial value y(0) of an integrator 14 in response to the load torque presumed value gammaL'. When the load abruptly varies, a switch 29 is closed in a short time and sets the initial value y(0) to the integrator 14. In this manner, the variation amount of the rotating speed is reduced.
