Title: Swr measuring device
Inventor: SANO MITSUO
IPC: G01R27/06
Filed: 1983-05-19
Abstract: PURPOSE:To read directly an SWR value by a simple operation with simple constitution by connecting rectifier diodes in reverse polarities to both terminals of a CM type directional coupler and detecting the position of a zero potential via the potentiometer between the diodes. CONSTITUTION:The voltage corresponding to a traveling-wave voltage and a reflected wave voltage are generated at both terminals on the secondary side of a transformer M of a CM type directional coupler consisting of a capacitor C and a current transformer M. The two terminals are respectively connected by detecting diodes D1, D2 having reverse polarities and the point where the voltage of a potentiometer RP connecting the diodes D1, D2 is zero changes according to the ratio between the two voltages. Therefore, if the scale of the SWR is provided to the rotation indicating part of the potentiometer and the zero voltage thereof is detected the scale indicated by the potentiometer is directly read by the SWR. The SWR is thus measured by the simple simultaneous operation with the simple constitution without making operations such as matching of the full scale and measurement.

Title: Compensating method for phase delay of armature current of synchronous motor
Inventor: TAKAKADO YUZO
IPC: H02P27/06
Filed: 1989-04-10
Abstract: PURPOSE:To compensate phase delay of real current to an applied voltage by detecting an induced voltage to form a magnetic flux signal, adding predetermined times of a signal of the phase leading from the signal to form a magnetic flux signal leading in phase, and controlling the phase of the voltage to be applied to an armature winding with the magnetic flux signal. CONSTITUTION:A magnetic flux PHIU is added, for example, by multiplying a W-phase magnetic flux signal PHIW by a predetermined value to generate a magnetic flux signal PHI'U leading in phase from the signal PHIU. This is also similar for V-phase and W-phase. Magnetic flux signals PHI'U, PHI'V, PHI'W leading in phase are supplied to a 3-phase inverter, not shown. As a result, since a base signal similarly leading in phase is applied to a transistor, the phases of the applied voltages of the phases lead, and the phase of the current flowing to armature winding lead. Thus, the phase delay due to the leakage impedance of the armature winding is compensated.

Title: Manufacture of reduction reoxidation type semiconductor porcelain element
Inventor: NOI KEIICHI
IPC: H01G4/12
Filed: 1989-04-07
Abstract: PURPOSE:To easily realize mass production by a method wherein, after porcelain is reduced, baked and reoxidized in order to increase electrostatic capacitance of an element, a highly resistive oxide layer formed on a semiconductor porcelain surface is eliminated by not using a mechanical method but by a manufacturing method. CONSTITUTION:An ohmic electrode is formed on one surface of a circular plate type reduction reoxidation type semiconductor porcelain, and a non-ohmic electrode is formed on the other surface. As to an element having the above structure, it is necessary that a highly resistive oxide layer formed on the semiconductor porcelain surface of only one side is eliminated and the semiconductor part is exposed after the porcelain is reduced, baked, and reoxidized. In order to solve this problem, the following processes are executed; reduction reoxidation type semiconductor porcelain material is used as main component, after this is molded, and binder is eliminated; reduction, baking, and reoxidation are performed in the manner in which one surface of the baked body is buried in oxygen diffusion retarder containing larger amount of material promoting to make the main component turn to semiconductor than the content of the semi conductor promoter in the main component. Hence the formation of a highly resistive oxide layer can be restricted, so that electrodes are directly formed on the semiconductor part, and electrostatic capacitance can be increased as compared with conventional elements.
