Filed: 1982-11-19
Abstract: PURPOSE:To improve accuracy with a broader scanning range by positioning a detection slit at least at two points to determine the detection position according to a detection signal of a photomultiplier tube, a scan signal of a scanning means and a position signal of the detection slit. CONSTITUTION:A detection slit position signal is outputted from a drive circuit B22 to position a detection slit 15a at the first position. Then, according to a scanning signal from a drive circuit A21, a galvanomirror 14 scans a section A on a surface 10 to be detected. As output level changes of an photoelectric converter 17 are read out with a comparator circuit 19 due to reflected lights from the object being detected through the detection slit 15a, a signal is applied to a sampling circuit 20. An arithmetic circuit calculates the position of an object 10a to be detected from signals currently from the drive circuit A21 and the drive circuit B22 and the sampling circuit read and outputs it. Upon the end of the scanning of the section A, the section B is scanned at the second position of the detection slit 15a. This can improve the detection accuracy with a broader scanning range.

Title: Eddy current type range finder
Inventor: HOSOE TOSHIAKI
IPC: G01B7/02
Filed: 1984-09-29
Abstract: PURPOSE:To obtain a high-precision eddy current type range finder which operates stably by providing a phase shift control circuit between one coil of a secondary coil made of a couple of coils of a DC sensor and an amplifying circuit which outputs the difference voltage between induced voltages of the secondary coils. CONSTITUTION:A synchronous detecting circuit 16 detects a difference voltage outputted from a signal amplifier 13 in synchronism with a phase-shifted AC signal from a phase shifting circuit 15 and outputs a DC signal corresponding to a phase shift component in the difference voltage. This DC voltage is inputted to the multiplier 14-1 of a voltage-capacity converting circuit 14 through a DC amplifying circuit 17. Consequently, electrostatic capacity Ce between a coil 10-3 and the uninverted input terminal of the signal amplifier 13 varies with the voltage value of the DC signal inputted to the multiplier 14-1. When the capacity Ce varies, the induced voltage eS2 of the coil 10-3 is shifted in phase and sent to the uninverted input terminal of the amplifier 13. Therefore, even if there is a phase shift between induced voltages of the secondary coil, it is compensated automatically. Then, the amplifier 12 outputs a voltage signal e0 corresponding to the distance between an eddy current sensor 1 and a body S to be measured.

IPC: G01N21/94
Filed: 1986-09-01
Abstract: PURPOSE:To reduce the cost required in the measurement of the contamination of an insulator, in an apparatus irradiating the insulator with ultraviolet rays to receive the reflected light from said insulator, by operating the reflectivity ratio of received lights to the different wavelength of ultraviolet rays to compare the same with that of a normal insulator. CONSTITUTION:The ultraviolet rays from a light source 1 are allowed to pass through a modulator 3 to be separated into ultraviolet rays and disturbance light to irradiate an insulator 4. The reflected light from the insulator 4 is received by a semipermeable mirror 6 and the transmitted light from said mirror 6 is allowed to pass through a filter 7 to be received by a light receiver 9 and the reflected light therefrom is allowed to pass through a filter 8 to be received by a light receiver 10. Wavelength lambda0, lambda1 of ultraviolet rays are received by the filters 7, 8 and converted to electric signals corresponding to the reception of light by the light receivers 9, 10 to be sent to amplifiers 11, 12. Said electric signals are further sent to an arithmetic processor 13 to operate the ratio I0/I1 of light receiving intensities and the reflectivity ratio of the received lights is compared with that of a normal insulator to measure the degree of contamination. Since the reflectivity ratio of the different wavelengths of ultraviolet rays is calculated, the contamination of the actually used insulator can be measured from a long distance and measuring cost can be reduced.
