Title: Photoelectric switch of multiple beam type
Inventor: NONAKA SHUNSUKE
IPC: H01H35/00
Filed: 1987-09-30
Abstract: PURPOSE:To obtain a multi-beam type photoelectric switch which makes a dedicated controller unnecessary and eliminates mutual interference by holding a multiplicity of light emitting sections and light receiving sections in one case and providing the light emitting section with a narrow band filter allowing a fundamental frequency component of modulation light to pass through. CONSTITUTION:A light emitting unit 21, a light receiving unit 22, or a light emitting and receiving unit is constituted by holding a multiplicity of light emitting sections 3a-3d and light receiving sections 4a-4d in single housings 20a, 20b. Frequencies of modulation light of respective light emitting sections 3a-3d are set to different frequencies. Narrow band filters for allowing fundamental frequency components only of the modulation light of respective light emitting sections 3a-3d to pass through are arranged to respective light receiving sections 4a-4d respectively corresponding to light emitting sections 3a-3d. This eliminates mutual interference, and makes a synchronous signal namely a dedicated controller unnecessary. As a result, a multi-beam type photoelectric switch can be obtained which causes no errors in operation even if each unit is connected in succession with a high reliability.

IPC: H01S5/30
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To measure temperatures accurately throughout the vapor growth. SOLUTION: A part where there is no interference of thermal radiation caused by a growth film is previously formed partly on the surface of a substrate.

Inventor: KAMOI HIROMUNE
IPC: G01F23/56
Filed: 1996-08-29
Abstract: PROBLEM TO BE SOLVED: To eliminate a lift mechanism for a sound wave transmitter/receiver and obtain a simple inexpensive detecting apparatus by setting a restraining mechanism for restraining the shift and rotation of a main body part having a sound wave transmitter/receive floating at a level of waste liquid. SOLUTION: A shift/rotation restraining mechanism 20 is set which allows a main body part 10 having a sound wave transmitter/receiver floating at the level of waste liquid to shift in a vertical direction following a change of the liquid level, and restrains the shift in a horizontal direction and the rotation about an axis assumed within a horizontal plane of the main body part 10. The restraining mechanism 20 is constituted of guide posts 27, 28, circular rings 23, 26 and coupling bodies 21, 22, 24, 25. While the main body part 10 moves up and down when a liquid level of filthy water changes, the shift in the horizontal direction and rotation of the main body part are restrained by the restraining mechanism 20. Even if the main body part 10 is apt to be inclined from the horizontal plane, the inclination is restrained as well.  A variation of measured data resulting from the propagation of inclined ultrasonic waves is thus prevented.
