Patent JP-H0446588-A (JP)
Title: Power converter
Inventor: DEGUCHI KAZUYUKI
IPC: H02P27/06
Filed: 1990-06-12
Abstract: PURPOSE:To suppress pulsation of current without increasing DC reactance of main circuit by detecting a pulsating current and calculating a correction amount based on a detection signal. CONSTITUTION:A current detecting circuit detects pulsation of current. Thus detected pulsating current is passed through a filter in order to take out a controllable pulsating current which is then differentiated through a differentiating circuit and multiplied by the reactance component of the circuit through a multiplier thus calculating a correcting amount. Since the correcting amount is equal to a voltage component Vc=LdiL/dt, pulsation of current can be canceled by inverting the correcting amount Vc. When the correcting amount(-Vc) in a formula L=diL/dt+(-Vc)=0 is applied on the phase control in a voltage control section, i.e., a converter, pulsation of current can be canceled and suppressed.

Title: Measuring instrument applying radiation rays
Inventor: FUJITA YURIKO
IPC: G01T1/24
Filed: 1988-06-21
Abstract: PURPOSE:To miniaturize the measuring instrument and to prevent an error caused by a deviation between a radiation source and a light receiving device by allowing the radiation sensitivity of a semiconductor detector to have a gradient. CONSTITUTION:A P type semiconductor wafer 10 consists of, for instance, CaTe, an (n) type layer 11 is formed by diffusing Al to one face of the wafer 10, and an Al electrode 12 and an Au ohmic electrode 13 are formed on the (n) layer side and the other side, respectively. Also, the detector is formed so that the radiation sensitivity is the weakest in an A part of the center part, and the sensitivity becomes stronger toward the B and the C directions of the outside periphery. Moreover, the detector having such a sensitivity gradient executes a heat treatment by allowing the inside of the wafer 10 to have a temperature distribution, for instance, at the time of diffusing Al. Said detector can be manufactured by varying the depth of p-n junction or forming a shielding film which becomes thicker as it goes to the inside on a light receiving part. In such a way, the measuring instrument can be miniaturized and an error caused by a deviation between a radiation source and a light receiving device can be prevented.
