Title: Selective ground-fault relay
Inventor: SATAKE SADAMITSU
IPC: H02H3/38
Filed: 1987-10-26
Abstract: PURPOSE:To promote the miniaturization of a device by providing a current transformer in the neutral point of a surge absorber. CONSTITUTION:When a ground-fault trouble is generated in a distribution line 4 providing stray capacity 6, a zero-phase current i2 from a surge absorber 7 and a zero-phase current i1 from the stray capacity 6 are allowed to flow in the distribution line in trouble. A flow of the zero-phase current i2 in a neutral point 7A of the surge absorber 7 is in the same direction toward an earth side both in a distribution line side of the ground-fault trouble and a sound circuit side, but a flow of the zero-current in its total value in a zero-phase current transformer 2 is in an opposite direction between the distribution line side of the ground-fault trouble and the sound circuit side. Since a selective earth protecting relay 3 operates only when it is in a direction of the zero-phase current i1, the distribution line 4 in the ground-fault trouble can be disconnected by breaking a switch 1. Thus because the flow of current is only through an earth line of the neutral point, the zero-phase current can be detected only by additionally providing a small current transformer, accordingly simplifying structure of a device, its miniaturization can be attained.

Title: Power supply box
Inventor: NAKAMURA MAYUMI
IPC: H01F27/02
Filed: 1995-10-17
Abstract: PROBLEM TO BE SOLVED: To surely fix lead wires and, at the same time, to improve the workability of power supply box assembling work by making parts of the surrounding wall of the transformer housing section of the power supply box independent from the other part of the wall and making the independent parts taller than the other part. SOLUTION: A transformer housing section 4 is formed in a power supply box 1 by surrounding the section 4 with a wall and parts 5a and 5b of the wall are made independent from the other part 6 of the wall. Then projections 8a and 8b are formed on the independent parts 5a and 5b and the parts 5a and 5b are made taller than the other part 6. Therefore, when a worker bends the parts 5a and 5b carrying the projections 8a and 8b on their internal surfaces when he puts a transformer in the section 4, the worker can carry out the work without touching the other part 6 of the wall. Therefore, the workability of the assembling work of the power supply box 1 can be improved.

Title: Grinding jig for ferrule end surface
Inventor: MIZUE TOSHIO
IPC: B24B41/06
Filed: 1986-11-11
Abstract: PURPOSE:To make it possible to grind the end surface of a ferrule highly accurately, by holding a sleeve in which the ferrule is inserted and held contacting to the center of a globe group at the upper side and to the center of a globe group at the lower side, both of which are held in a housing contacting each other. CONSTITUTION:A ferrule 4 used for a photoconductor and the like is inserted in sleeve 15, held projecting a little from the lower end surface of a housing tube body 13, and contacted to a grinding paper 5. And by moving this grinding jig along the grinding paper 5, the position of the ferrule 4 is never displaced, and the angle between the ferrule 4 and the grinding paper 5 is kept at 90 deg., because the sleeve 15 in which the ferrule 4 is inserted is contacted to and held by the lower side and the upper side three globes 11 and 12, which are enclosed inside by the tube body 13 and its lid 14. Since the lower side globes 11 are rotated point-contacting to the grinding paper 5, the jig can move smoothly. In such a way, the end surface of the ferrule can be ground at a high accuracy and easily.

Abstract: PURPOSE:To jumpedly enhance the resolving power for detecting a distance by emitting a pulse beam onto an object in a timing synchronized with a clock pulse, and by subjecting the reflected pulse thereof to a photoelectric conversion. CONSTITUTION:The pulse beam emitted from a pulse laser 1 is reflected by an object 10, and the reflected pulse beam is input into a photodetector 3 where the beam is subjected to a photoelectric conversion and then is amplified for outputting a signal.
