Title: Semiconductor photodetector
Inventor: TERAKADO TOMOJI
IPC: H04B10/40
Filed: 1989-02-28
Abstract: PURPOSE:To obtain a dual-balanced-type photodetector of high performance by forming an isolation groove between adjacent photodiodes down to a semi- insulating InP substrate and forming a high-resistance semiconductor layer consisting of GaAs or AlGaAs in said isolation groove. CONSTITUTION:An isolation groove 15 is formed between adjacent photodiodes down to a semi-insulating InP substrate 10. In this isolation groove 15, a high- resistance semiconductor layer 16 consisting of GaAs or AlGaAs is formed. An interface between InP and GaAs or AlGaAs is electrically stable and an interface between GaAs or AlGaAs and an SiNx protective film is also electrically stable. By forming a high-resistance semiconductor layer 16 consisting of GaAs or AlGaAs in the isolation groove 15 cut down to the semi-insulating InP substrate 10, a leakage current through an interface level of InP can be prevented. Accordingly, the dual-balanced-type photodetector of high performance in which the photodiodes have little and equal dark currents can be obtained.

Title: Magnetic disk control system
Inventor: INOUE YUUJI
IPC: G11B19/04
Filed: 1983-03-23
Abstract: PURPOSE:To eliminate the use of a writing protection switch by forming a writing inhibition flag in a flag region of a track format of a magnetic disk and performing the writing to said track only with a writing permission bit command given from a processor. CONSTITUTION:A writing deciding circuit 8 of a magnetic disk controller 2 decides the writing permission bit given from a processor 1 via a command control part 7 and produces a low level decision output in a writing permission mode to close an AND gate. Therefore the signal which detected the inhibition flag of the flag region of a flag format of each track of a magnetic disk which is delivered from a writing inhibition flag detecting circuit 10 is not transmitted to the control part 7. Then the writing is carried out to the corresponding track, and the writing is inhibited when the writing permission bit is inhibited. In such a constitution, a writing protection switch became useless. Thus the data is protected for each track with no manual operation of switches including said protection switch.

Title: Ac/dc converter controlling device
Inventor: OTSUKI MIDORI
IPC: H02M7/12
Filed: 1992-03-05
Abstract: PURPOSE:To privide a controlling device for an ac/dc converter by which an over voltage during a trouble or after removal of the trouble can be controlled by continuing the operation of the converter even if the trouble occurs in the a.c. system and the trouble is such one that the converter can continue stable operation. CONSTITUTION:When an ac/dc converter has a one-phase grounding trouble in an ungrounded system, voltage to ground of the trouble phase decreases due to grounding and then a full-wave rectified waveform of the voltage to ground obtained by a.c. voltage detectors 16-18, absolute value circuits 19-21 and a maximum voltage selecting circuit 22 decreases and therefore the output 24 of a level detector 23 detects a voltage drop and goes to '1'. On the other hand, a line voltage when the one-phase grounding trouble occurs in the ungrounded system has the same vector diagram and the same waveform as the one in the normal condition and the output 36 of the level detector remains '0' as is in the normal condition and therefore a converter protective circuit 37 does not operate. If the trouble is such one that the a.c. voltage to ground decreases but the a.c line voltage does not decrease, the converter can be operated continuously and thereby an a.c. over voltage can be controlled.

Title: Alkaline manganese battery
Inventor: OOTA AKIRA
IPC: H01M10/52
Filed: 1980-04-11
Abstract: PURPOSE:To facilitate the absorption of oxygen gas generated during over discharge or charging  of a battery, by using a gel-like zinc negative electrode an air-room side end of which contains a  higher concentration of dispersed amalgamated zinc powder than the inner part of that. CONSTITUTION:A positive electrode 2 made manganese dioxide, and a gel-like negative electrode  3 containing zinc are placed opposite to one another, with a separator 4 interposed between them.  The concentration of an amalgamated zinc powder dispersed in the gel-like electrolyte of an end  part 3', which is a part of the negative electrode 3 and touches an air room 6, is made higher  than that of the amalgamated zinc powder dispersed in the electrolyte of the inner part of the electrode 3. The electric capacity of the end part 3' containing a higher concentration of dispersed  amalagamated zinc powder is preferably 10-20% of the capacity of a positive electrode. The  electric capacity of the negative electrode is preferably 100-120% of the capacity of the positive  electrode. Owing to the above constitution, oxygen gas, which is generated from the positive electrode either when reversal is developed due to over discharge or when charging is carried out, can  be easily absorbed. Consequently, any rise of the internal gas pressure of a battery can be prevented, and the explosion as well as the breakdown of the battery can be obviated.
