Title: Detection system for absolute position
Inventor: SAKAMOTO KEIJI
IPC: H03M1/30
Filed: 1987-02-21
Abstract: PURPOSE:To reduce the power consumption of a detection system and to enable high-accuracy detection by holding a counted value by an absolute counter which counts feedback pulses from a detector even when the power source is off, and detecting an absolute value with the number of interpolated pulses generated from power-on operation to a final pulse and the value when the power source is turned off. CONSTITUTION:The feedback pulses from the detector which are inputted to the absolute counter 2 are divided equally by N with interpolated pulses. Here, when the power source is off, the value stored in the counter 2 is denoted as B and the absolute position of the actual stop position of the detector is denoted as P. Then when there is a command for movement to a positive position X is generated for a 1st time after the power source is turned, its movement quantity is X-P and when the number (a) of interpolated pulses until a feedback pulse is generated first is detected, P=Bk+(N-a)m. Here, the distances of a feedback pulse and an interpolated pulse are denoted as (k) and (m) respectively. For the purpose, the position P at the time of power-off operation is found by detecting the number (a) and the absolute position is set at the position X by performing movement by the movement quantity X-P.

Filed: 1995-02-24
Abstract: PURPOSE: To high-precisely discriminate the output fluctuation limit of an engine and to advance a state that an air-fuel ratio is brought into a lean state and the retard of an ignition timing within a range not to exceed an output fluctuation limit. CONSTITUTION: A standard deviation between given cycles of a value IMEP obtained by integrating a pressure in a cylinder at a give section and an average value thereof are computed at S3-S6.

Title: Vapor growth method for compound semiconductor crystal
Inventor: SHIMAZU MITSURU
IPC: H01L21/205
Filed: 1990-02-20
Abstract: PURPOSE:To well control the quantity of doping of carbon by specifying growth pressure and growth temperature and changing the total gas flow when doping it with carbon using organic metallic compound as group V material. CONSTITUTION:In the organic metal vapor growth method for III-V compound semiconductor, when doping it with carbon using an organic metal compound as group V material, the total gas flow is changed with growth pressure 1-40Torr and growth temperature 625 deg.C or less. That is, when total gas flow is changed with growth pressure maintained constant. the gas flow speed changes, the residence time at the surface of the substrate of the organic metal compound being material changes, so the rate of the decomposition of the organic metal compound also changes. Hereby, the quantity of doping with carbon can be controlled in wide range without changing the growth temperature.

IPC: H03K19/003
Filed: 1979-03-30
Abstract: PURPOSE:To prevent the malfunction of the IC element due to the noise by providing the noise absorbing circuit to the input step of the IC element. CONSTITUTION:When the output of IC1 changes to the low level from the high level due to the noise, the current flows to the branch lines of resistance R1, diodes D1 and D2 plus capacitor C2 each. As a result, transistor Tr1 conducts to raise forcedly the input level of IC2 up to VCC. And in case the output of IC1 is turned to the high level from the low level due to the noise, the current flows to the branch lines of capacitor C3, diodes D3 and D4 plus resistance R4 each. As a result, Tr2 conducts to lower forcedly the input level of IC2 down to the earth level. In this way, the malfunction due to the noise can be prevented for IC2.

Abstract: PURPOSE:To prevent air bubbles mixed-in during treatment from approaching the circumference of a specimen, by introducing the specimen into a treatment tank in a state received in a case made of a net having fine meshes. CONSTITUTION:After a specimen is introduced into a treatment tank 1, the upper opening of the treatment tank 1 is closed by a lid 2 and the treatment liquids stored in a plurality of containers 3, 3 are successively sent into the treatment tank 1. The selection of the treatment liquids is performed by changing over the rotary value 4 provided on the way of the pipings connecting the containers 3, 3 and the treatment tank 1. Further, the atmospheric pressure in the treatment tank 1 is made negative or positive by the operation of a liquid feed pump 5 or through a supply and discharge pipe 6 to perform the supply and discharge of the treatment liquids with respect to the treatment tank 1. The treatment liquids subjected to the treatment of the specimen in the treatment tank 1 are discharged to a waste liquid container 7 by changing over the valve 4 to such a state that the treatment tank 1 communicates with the container 7. Whereupon, the air bubbles mixed with the treatment liquids introduced into the treatment tank 1 can not pass through meshes and only the treatment liquids advance into the treatment tank 1. As a result, the adhesion of air bubbles to the surface of the specimen can be prevented.
