Patent JP-H01274681-A (JP)
Title: Controller for cycloconverter
Inventor: OKABE JUNICHIRO
IPC: H02P27/04
Filed: 1988-04-25
Abstract: PURPOSE:To avoid an instability under control and to prevent an unstable phenomenon due to an insufficient voltage by providing a torque current set value variable limiter for monitoring an ignition angle to detect an insufficient voltage, and limiting a torque current. CONSTITUTION:A torque current set value variable limiter 50 monitors the ignition angle of a thyristor to be formed by a gate controller 11, and gradually limits a torque current reference when the ignition angle arrives at an ignition angle limiter for a set time or more. When the torque current reference is reduced, a voltage to be applied to an induction motor 36 is reduced, and the angle does not reach the limiter. Thus, an instability under control can be avoided.

Title: Memory ic driving system
Inventor: KANEDA SHIGEO
IPC: G11C29/00
Filed: 1978-08-22
Abstract: PURPOSE: To realize reduction of the number for the error occurrence bits by securing a fixed connection between the memory IC and the memory IC driving buffer gate.  
     CONSTITUTION: The writing/reading is given to IC memories 1 forming a number of IC memory groups in accordance with the bit signals given from registor 3. About 8 units of memory 1 among these memory groups which belong to the same group and receive the simultaneous writing and reading are connected with every 4 units in parallel to memory IC driving buffer gate 5 to be then driven with every two units by the driving signals sent from gate 5. As a result, the error is reduced down to 2 bits even in case gate 5 has some fault, thus preventing the error for many bits beyond the correction/detection capacity of the error correction code. In such way, the fault can be detected by the detection capacity of the error code to omit the fault detecting additional gate.

Filed: 1979-08-10
Abstract: PURPOSE:To enable to connect the output earlier, by the control of DC voltage through the use of a timer which operated with less delay time the higher the input level. CONSTITUTION:When the receivers 1-3 receive electromagnetic waves, the output of the receiver 1 is low, that of the receiver is high and that of the receiver 3 is middle, according to the respective input level, for example.

Title: Reciprocating driving system of ultrasonic motor
Inventor: UEDA TOMOO
IPC: H02N2/00
Filed: 1990-04-18
Abstract: PURPOSE:To reciprocate a standing-wave ultrasonic motor by alternately exciting A- and B-phases in the stator of the ultrasonic motor, where an annular-type piezoelectric element is secured to the stator and the A- and B-phases on the side of the surface opposite to a common electrode on the stator side have electrode arrangements deviating by 1/4 wavelength from each other and electrodes in each phase are alternately polarized in opposite directions. CONSTITUTION:Signs + and - express the direction of polarization of each electrode. The rear surface of a piezoelectric element is conductively stuck to a metal stator, its front surface is almost bisected into A- and B-phases, and electrodes in each phase are positioned in the manner of deviating by 1/4 wavelength. When the A-phase is excited singly, a waveform is placed in a state 6 and in a state 7 when the B-phase is excited singly. The stator generates a torsional oscillation at a specific resonance frequency by a longitudinal oscillation. A rotor revolves in one direction by this torsional oscillation. In the waveforms 6 and 7, however, the directions of the torsional oscillations are reversed mutually. Thus, the reciprocating rotation of a standing-wave ultrasonic motor can be realized, when the A- and B-phases of the piezoelectric element are excited alternately.

Abstract: PURPOSE:To estimate the degradation of insulation of equipment from the ratio between the  number of oxygen atoms and the number of carbon atoms, by utilizing the fact that the number  of oxygen atoms against the number of carbon atoms in insulating resin increases due to a  thermal-oxidation degradation. CONSTITUTION:A thin leaf shaped insulating material is wound around an iron core. Glass tape is wound around it and fixed. Then, low viscosity epoxy series varnish is impregnated in a vacuum, and a coil test bars are obtained, after the hardening in an electric funace at 135 deg.C. Under the same condition, a resin plate having a thicknes of 1mm. is obtained, and monitoring resin pieces are obtained from said plate. The rest bars and the monitoring pieces are put into the electric furnaces whose temperature as set at 180 deg.C, 210 deg.C, and 230 deg.C, respectively, and are subjected to thermal oxidation degration. After the specified time, the test bars are taken out and the insulaton breakdown voltage is measured. At the same time, the monitoring pieces are crashed, and the weights of the hydrogen atoms and the carbon atoms are measured. From these values the ratio between the number of oxygen atoms and that of carbon atoms is comouted. Since the rate of change of the breakdown voltage corresponds to the thermal oxidation degradation time and the atomic ratio corresponds to the thermal degradation time, the degree of the insulation degradation can be estimated based on this fact.
