Title: Capacitor type welding power supply
Inventor: SHIROCHI TAKASHI
IPC: H02M9/00
Filed: 1988-03-15
Abstract: PURPOSE:To minimize a power loss by charging a capacitor with a constant current. CONSTITUTION:A reference waveform generator circuit 10 for a charging control circuit generates a reference waveform signal GE decreasing linearly due to the negative polarity during a charging period to reach a specified saturating value in a specified time. Said saturation value is regulated by the output signal of a voltage setting circuit 12, and a charging voltage detector circuit 14 detects the momentary charging voltage EC of a capacitor charging during said charging period and outputs a signal S. In said charging control circuit, said charging voltage EC rises linearly due to the positive polarity during the charging period and reaches the saturated value at the end. Said both signals GE, S are added via buffer circuit composed of operational amplifiers 16, 18 and resistances 20, 22 so that an error signal ER is formed from the error er thereof by an operational amplifier 24 and the like. Said signal is compared with the triangular wave signal TR of a triangular wave generator circuit 34 by an operational amplifier 32 to generate a rectangular wave output signal GO.

Title: Optical apparatus for measuring displacement
Inventor: HISAKUNI AKIRA
IPC: G01C3/06
Filed: 1988-03-14
Abstract: PURPOSE:To take in a signal without impairing a dynamic range of a converter, by a method wherein an addition value of voltage signals of two systems from a one-dimensional position detecting element is used as a parameter to control a reference voltage for a differential amplifier and the converter. CONSTITUTION:A one-dimensional position detecting element 1, which converts light signals of a regularly reflected light and a scattered light out of light beams reflected by a substance to be measured into electric signals, outputs current signals I1 and I2 of two systems from opposite-end electrodes in accordance with the intensity of an imaged light beam and an imaging position. These current signals are converted into voltage signals V1 and V2 by a current/ voltage converter 8. An adder 11 adds up these voltage signals. Based on an output from the adder 11, differential amplifiers 12 amplify the voltage signals V1 and V2 differentially with appropriate gains respectively. An output voltage from the adder 11 is inputted as a reference voltage to an analog/digital converter 13, which subjects an output of the differential amplifier 12 to digital conversion.

Title: Method and device for positioning control
Inventor: YASUI TAKESHI
IPC: G05B11/36
Filed: 1994-03-30
Abstract: PURPOSE:To provide a method and device for positioning control capable of deciding a control command by finding input/output characteristic between the control command and the operation of a controlled system with high accuracy, and surely making the controlled system execute a desired operation. CONSTITUTION:Input 1 is calculated from a desired response O by using a transfer function H1 found from known input and response first, and it is taught to a positioning device as target input position data. At this time, when the error of an obtained response 1 is not converged within a desired allowable value, a transfer function H2 is calculated by using a response O1 in a frequency area by equation (Hi+1(jomega)=Oi(jomega)/Ii(jomega)). New input 2 is calculated from the desired response by using the function H2, and it is set as the target input position data. Positioning with high accuracy can be performed by repeating such operation until the error can be converged, and repeating it until a prescribed control result can be obtained as correcting the transfer function.

Title: Control method for cyclo-converter
Inventor: OKAYASU MASAMI
IPC: H02M5/27
Filed: 1990-03-13
Abstract: PURPOSE:To enhance input power factor by employing symmetric control or asymmetric control depending on the operating range of a motor and switching the control system continuously and smoothly thereby enabling high speed operation without disturbing the waveform of output voltage. CONSTITUTION:At first, a conversion output voltage E is set according to formula I. Here, Cc is a DC current and thetaOv is a voltage phase. When a DC voltage Vc is set equal to Ealpha, EU1S = Ea is satisfied. When the DC voltage Vc is lowered gradually to 0, formula II is satisfied. Control is carried out similarly also in case of EU<0. When the DC voltage Vc is made variable as a function of speed, switching can be made continuously from asymmetric control to symmetric control without varying the voltage EU to be applied on a motor. Consequently, high speed operation with good output characteristics is realized without causing disturbance in the output voltage waveform under high speed while improving input power factor under low speed operation.

Abstract: PURPOSE:To eliminate both of the addition of impurity element of III-group or V-group and the high temperature heat treatment of a substrate by a method wherein the surface of a p-type silicon substrate is heated by a laser beam to form a p-n junction. CONSTITUTION:A silicon nitride film 2 is formed on the surface of a p-type silicon substrate 1 to improve a heating efficiency.

Short time heat treatment at about 650 deg.C is carried out to eliminate the oxygen donors and convert both of the heated region 4 and the silicon substrate 1 into p-type. Finally, short time heat treatment at about 450 deg.C is carried out to activate the oxygen donors in the heated region 4 and convert the heated region 4 into n-type. Thus, a p-n junction consisting of the n-type heated region 4 and the p-type silicon substrate 1 can be formed.

Abstract: PURPOSE:To reliably detect the completing time of the starting, by a method wherein a combustion flame image is propagated from the one end to the other end of an optical fiber for detection, and completing of the starting of an internal-combustion engine is detected from the fact that the detected collecting level exceeds a given value.
