Title: Photoelectric converting circuit
Inventor: MANABE SATOSHI
IPC: G02B6/42
Filed: 1995-09-13
Abstract: PROBLEM TO BE SOLVED: To provide the photoelectric converting circuit which can prevent noise and distortion due to a return of a light signal reflected by a photodetection surface to the photodetection surface from increasing. SOLUTION: Light from an optical fiber 17 passes through an optical isolator 15 as shown by an arrow 19 and is photodetected by a pin photodiode 12. The optical isolator 15 does not pass the light in the opposite direction from the arrow 19, so the light reflected by the photodetection surface 13 never returns to the optical fiber 17. The light reflected by the photodetection surface is made incident on the optical fiber 17 and reflected by a reflection part such as an optical connector 18, so that it never returns to the photodetection surface, so noise and distortion due to the reflected light can be prevented from increasing.

Title: Displacement detector
Inventor: FUKUHARA KATSUHIKO
IPC: G01D5/20
Filed: 1987-09-17
Abstract: PURPOSE:To reduce detecting errors and to make it possible to ensure positive measurement of displacement, by using coils which are wound with high temperature superconductors as resonance circuits, and detecting the displacement of a displacing member facing the circuit from the change in resonance frequencies. CONSTITUTION:Primary and secondary coils 1a and 2c are wound with high temperature superconductors. The coil 2c is displaced in a facing pattern with the coil 1a. The coil 1a is excited with an AC power source 4 and the frequency of the current is changed. The resonance frequency, when the value of an AC ammeter 7 becomes the minimum value, is obtained. Then, the position of the coil 2c is changed, and the resonance frequency of a circuit is obtained by the same way. Q of this resonance circuit becomes large since the resistances of the coils 1a and 1c are close to zero. Therefore, the resonance frequency can be obtained accurately. Thus the displacement can be detected from the difference between both frequencies.
