Abstract: PURPOSE:To realize a thin film material having a high saturation flux density and an excellent soft magnetic characteristic, by forming a soft magnetic alloy film having a specific composition which is expressed with composition formula FeaMcOd. CONSTITUTION:A film is formed by sputtering in an atmosphere of Ar+O2 by using an RF magnetron sputtering apparatus and by using a composite target constructed by disposing various pellets of Y, Ce and the like on an Fe target.

Title: Output short-circuit protection circuit for transistor
Inventor: ATSUMI ISAO
IPC: H03K17/08
Filed: 1988-02-29
Abstract: PURPOSE:To attain miniaturization by using an interruption circuit so as to turn off a transistor(TR) at its output thereby applying positive feedback to a voltage detection circuit in a way of increasing its detection signal. CONSTITUTION:A current sensing resistor R1 detects a collector current of a TR Q1, a voltage across the resistor R1 is fed to a voltage detection circuit 1, which discriminates it that the load is short-circuited when the voltage across the resistor reaches a prescribed value or over and gives a detection signal to an interruption circuit 2. The interruption circuit 2 receiving the detection signal turns off the TR Q1. On the other hand, the interruption circuit 2 applies positive feedback to the voltage detection circuit to increase the detection signal supplied to itself. Thus, the TR Q1 driving the load is forcibly turned off in the event of output short-circuit, resulting in giving no current through the current sensing resistor R1. Since the current sensing resistor R1, with a small rated power is enough and the TR Q1 with a small rated current is sufficient for the protection circuit, the circuit is made small in size and low in cost.

IPC: G02B5/08
Filed: 1989-02-23
Abstract: PURPOSE:To obtain a reflecting mirror which has a high reflection factor by forming its reflecting surface of crystal particles which have the same crystal orientation. CONSTITUTION:A surface which is perpendicular to the solidifying direction 2 of a cast ingot which is solidified, for example, in one direction or an optional cut surface of a single crystal body is applied to the reflecting surface. Here, the unidirectionally solidified cast ingot consists of structure wherein columnar crystals 1 are grown in parallel to the solidifying direction 2, and the growing direction of each columnar crystal is <100> when copper or copper alloy is used, so that the surface which is perpendicular to the solidifying direction of the cast ingot is a surface consisting of (100) surfaces of the columnar crystals. Consequently, when the surface is polished specularly, a polishing irregularity due to a difference in crystal orientation is not generated and the entire reflecting surface is polished homogeneously to obtain the high reflection factor.

Title: Method and equipment for controlling charge/interruption of compressor for automobile air-conditioning facility
Inventor: BIRUHERUMU BARUSHIEKE
IPC: F24F11/00
Filed: 1996-03-01
Abstract: PROBLEM TO BE SOLVED: To prevent freezing of an evaporator and accomplish a high cooling output by setting a shutoff temperature with a specified value so that the shutoff temperature drops with an output of an evaporator fan or increase of an intake air temperature depending on the output of the evaporator fan and/or the temperature of the air drawn by the evaporator fan. SOLUTION: A power switch 1 connected to a compressor clutch is operated by an operation step including an operational amplifier 2 and a resistance R1. Decreasing a fan voltage of an evaporator, accordingly decreasing an output of an evaporator fan, causes to drop a voltage of a center tap K1 of a first voltage divider, accordingly a voltage of a non-inversion input side of the operational amplifier 2. As a result, a desired higher shutoff temperature Taus is adjusted. Similarly, decreasing an intake air temperature, accordingly decreasing an electric resistance of an intake air temperature sensor, causes to drop the voltage of the center tap K1 of the first voltage divider to provide the desired higher shutoff temperature Taus again, wherein the shutoff temperature Taus can be set so that a temperature of the evaporator is located at 0 deg.C or above.

Abstract: PURPOSE:To make both characteristics of tightness of a film with a protected body and surface hardness compatible, by coating the body to be protected with the boron-added amorphous silicon carbide film having hardness changeable in the direction of the thickness. CONSTITUTION:After a body to be protected (metal wiring) 2 is provided on a substrate 1, the body 2 is coated with a boron-added amorphous silicon carbide film 3 using a GD method or an SP method.

In the GD method, mixed gas of silane, hydrogen carbide, hydrogen and diborane is decomposed in plasma generated with grow discharge to form the boron added amorphous silicon carbide film. Changing a partial pressure of the diborane controls boron quantity in the film.

Filed: 1990-02-26
Abstract: PURPOSE:To perform detection with high reliability by calculating the predictive value of the present access code by using the past travel speed of an optical head before sampling the present access code and a sample value before one sample. CONSTITUTION:The relation C=¦An-ACn¦ of the predictive value An and the sample value ACn(=L2) of an actual n-th access code is computed by using an absolute value subtractor 14, and when it is C>=D i.e. difference between the predictive value and an actual value exceeds a constant value D, the switching operation of a selector 7 is performed assuming that it is ERR=H, and selection is switched to the one to the predictive value An side. In such a state, a latch 8 latches the predictive value An by changing the value(=ACn) by the sample value B with a sampling pulse PLS2 with little delayed timing. When the correction of the content of the latch 8 is completed, an ERR signal goes to an L level. Thereby, it is possible to detect the traversing number of tracks with high reliability.
