Title: Rotating speed control of induction motor utilizing zero-point switch
Inventor: MATSUDA TADASHIGE
IPC: H02P27/16
Filed: 1986-10-21
Abstract: PURPOSE:To eliminate a noise due to a switching by switching a control switch by the zero-point of a power source. CONSTITUTION:A zero-point detector B detects zero volt when the voltage of an AC power source A is altered from positive to negative. A microcomputer C produces a signal (c) for closing or opening a zero-point switch D at next zero-point every time informed of the zero-point. The switch D opens or closes the switch by the signal (c) from the microcomputer C when the momentary value of an AC voltage becomes zero volt. An intermittent waveform started from the zero-point is obtained by opening or closing the switch to be supplied to an induction motor M.

Title: Flow rate controller
Inventor: KUROMARU TATSURO
IPC: G05D7/06
Filed: 1990-09-20
Abstract: PURPOSE:To prevent a valve from being clogged with dust by alternately and periodically increasing/decreasing opening degree of plural valves provided in series based on the measurement result with a flowmeter. CONSTITUTION:A valve part 2 consists of two valves 21 and 22 provided in series with respect to a pipe line 1 and the opening degree of these valves 21 and 22 are respectively controlled by a control circuit 4 and alternately increased/decreased at a prescribed time interval. Either one of these valves is always kept at a set opening degree (varies corresponding to a detection result of a sensor part 3) to obtain the value of a set flow rate and the opening degree of the other valve is kept at that enough larger than that of the former valve. Thus, even if the valve to be kept at the set opening degree is clogged with dust, the dust can pass through the valve because the opening degree of the valve is increased after a prescribed period of time and clogging of the valve can be eliminated.

Title: Formation of lift-off pattern
Inventor: CHIBA AKIRA
IPC: G03F1/68
Filed: 1988-10-04
Abstract: PURPOSE:To improve reliability and precision in the sputtering deposition of a metal film by heating a resist to a temperature not lower than the transition point so that the defect density is decreased. CONSTITUTION:A predetermined resist pattern 10 is formed on a substrate, and a metal film 20 is formed on the exposed part of the substrate and on the pattern 10 by sputtering deposition. The sputtering deposition is carried out by controlling the temperature of the pattern 10 so as to be not lower than the transition stress temperature and not higher than the glass transition temperature of the resist. Further, the displacement amounts of the metal film 20 and the resist film due to stress are equal if the metal film 20 and the resist film are in close contact with each other at the interface A-B therebetween and if there is no relative movement at the interface. Accordingly, the stress in the pattern 10 is reduced and the defect density after the lift-off is decreased so that a lift-off pattern with high reliability and high precision can be obtained.

Title: Method for correcting gap and controller of rolling mill equipped with horizontal bending mechanism
Inventor: MINOURA KOJI
IPC: B21B37/00
Filed: 1994-10-18
Abstract: PURPOSE: Not to vary a gap between working rolls even when operating a bending cylinder by memorizing a rolling load and adjusting a hydraulic drawing down force for rolling with a memorized value so that the varied quantity of a rolling load during the operation of the bending cylinder becomes the minimum. CONSTITUTION: Rolling working is performed by working rolls 1 and 2, and the crowns of the working rolls 1 and 2 are controlled by horizontal pushing devices 12 and 13. The rolling loads of the working rolls 1 and 2 before the crowns are controlled by a hydraulic drawing down controller 24, are memorized by a memory. When the horizontal pushing devices 12 and 13 are worked to control the crowns, the rolling loads of the working rolls 1 and 2 are varied. The varied rolling loads are compared with the rolling loads memorized by a memory 24a with the hydraulic drawing down controller 24, and a hydraulic drawing down force for rolling is increased and decreased so that an original rolling load is attained. Therefore, influence such as mechanical hysteresis, the hysteresis of a pressure in a bending cylinder, etc., is eliminated, and a variation in plate thickness can be reduced.
