Abstract: PURPOSE:To stabilize power supply and to enhance work efficiency by laying a line for supplying high frequency sine wave current along a guide path for a moving object and providing the moving object with a pickup coil for inducing electromotive force in resonance to the frequency of the current flowing through the line. CONSTITUTION:Three-phase AC 200V power from an AC power supply is converted through a converter into DC power which is then inverted through a sine wave resonance inverter into high frequency AC power to be fed onto an inductive line 21. Consequently, the inductive line 21 produces flux which induces a high electromotive force in the pickup coil 27 of a moving body 22. Thus induced AC power is then converted through an AC/DC converting section 28 into DC power which is then fed through a motor controller 30 to a motor 29 where the traveling wheels 2 are driven to move a moving object 22 along a guide path 4. According to the constitution, noncontact power supply can be realized during travel of the moving object resulting in the enhancement of work efficiency.

Title: Switching deice for optical fiber sensor
Inventor: SHINOHARA HIDENOBU
IPC: G01S11/00
Filed: 1986-01-23
Abstract: PURPOSE:To simplify operation and to prevent the generation of mismeasurement by making polarized light pass a corresponding photodetecting fiber when the polarizing angle of the light source side coincides with that of the photodetecting side at the rotation of a polarizing plate. CONSTITUTION:A polarizing light source 5 is rotated by rotating the polarizing plate on the light source side by a rotating mechanism 7. Although all photodetecting fibers 9 on the photodetecting side can receive polarized light due to the light source side polarizing plate 6, only a pair of photodetecting fibers arranged on the polarizing plate arranged in the same direction of the polarizing light source can receive the polarized light into their fibers. The direction of the fiber transmitting the signal supplied to an output terminal can be known by previously regulating the rotational direction and the speed of polarizing light source and the polarizing angle of the polarizing plate 8 on the photodetecting side. Consequently, switching can be automatically attained and mismeasurement or troublesome operation can be removed.

Title: Temperature detecting system for printed board
Inventor: NAKAMURA SHIGEO
IPC: G01K11/12
Filed: 1989-01-19
Abstract: PURPOSE:To eliminate the need of a temperature sensor and to prevent the constitution of a circuit in a device from being complicated by detecting the variation of the quantity of light which passes the transmittance varying body of a printed board and is made incident on a photodetector as the variation of temperature. CONSTITUTION:The plural printed boards 1 are mounted to a backboard 9 through connectors. The transmittance varying bodies 2 are inserted into light passing holes 5 penetrating the same positions on the surfaces of the boards 1. Light radiated from a light source 3 passes all the varying bodies 2 and is made incident on the photodetector 4. When the temperatures of all the boards 1 are normal, the light radiated from the light source 3 is made incident on the photodetector 4 with hardly receiving the attenuation of the quantity of light by the varying bodies 2. Therefore, an information mechanism part 7 is not actuated. When abnormality is found even in one board 1 and the temperature abnormally rises, the varying body 2 of the board 1 loses the transmittance of light. The light radiated from the light source 3 receives the attenuation of the light by the varying body 2 and the quantity of light made incident on the photodetector 4 gets smaller than a specified value. Then, the information mechanism part 7 is actuated to light a warning lamp 8.
