IPC: G01B17/00
Filed: 1982-12-25
Abstract: PURPOSE:To take a safe, high-precision measurement in nuclear power facilities, etc., by providing an ultrasonic wave reflector between a size measuring probe and a body to be measured, and taking the size measurement on the basis of an echo from the reflector as a reference point. CONSTITUTION:A synchronizing signal N1 generated by a synchronizing signal generating circuit 3 is sent to a transmitter circuit 5 through a cable. A transmit voltage P1 is generated there and used to emit an ultrasonic wave from the size measuring probe 2a. A part of the ultrasonic wave emitted by the size measuring probe 2a is reflected by the reflector 9a to generate a reflected echo Q1, which is detected by the size measuring probe 2a; the remainder is reflected by the internal surface of a pressure tube 1 and detected as an echo signal S1 again by the size measuring probe 2a. A size measuring circuit 4 regards the echo signal Q2 as a reference signal to start a time measurement and also finishes the time measurement by a echo signal S2.

Title: Frequency control motor
Inventor: KATOU HAJIME
IPC: H02P23/16
Filed: 1982-12-28
Abstract: PURPOSE:To integrate the entire drive circuit in a 1-chip element by obtaining a frequency proportional to the rotating speed from a detection signal of a position detector. CONSTITUTION:A detection signal D applied to a position detector 4a is added to an adder 4d, which adds it. A detection signal D is outputted in frequency proportional to the rotating speed. Accordingly, its addition output pulse train is proportional to the rotating speed. Since a monostable multivibrator 4e is triggered by the addition output, this output becomes the pulse train proportional to the rotating speed. In other words, the voltage proportional to the frequency of the detection signal D of a position detector is obtained, thereby performing so-called a frequency/voltage conversion. Then, the output voltage of a low pass filter 7 is applied to a control circuit 4c to control the rotating speed, thereby controlling the frequency.

Filed: 1988-09-20
Abstract: PURPOSE:To improve the measuring accuracy of the height regardless of the distribution condition of the brightness of an inspection object and to inspect the three-dimensional shape of the inspection object at a high accuracy by using actively a comparatively bright part in it and measuring the height. CONSTITUTION:The height of a substrate 2A with a comparatively small light reflection factor is measured by using a substrate height distribution S3 prepared by an interpolation method at a substrate height distribution preparing circuit 7 based on the position of the bright part in the substrate 2A registered beforehand in a position registering memory 6 and the height data corresponding to the position. Consequently, even at the time of being the comparatively dark substrate 2A, by using the comparatively bright part in it, namely, the part where the accuracy of the height measurement is comparatively satisfactory, the dispersion of the height measurement can be suppressed to the minimum. As the result, the reduction of the arithmetic accuracy in a height deciding circuit 8 can be prevented.
