Title: Troubleshooting method for flame detector
Inventor: KAWAHITO AKIYOSHI
IPC: F23N5/24
Filed: 1981-03-27
Abstract: PURPOSE:To facilitate troubleshooting for a flame detector of a burning device which fails to ignite by comparing the temperature of the exhaust gas immediately before the start of ignition with that of the exhaust gas immediately before the start of non-ignition on the basis of the ignition and non-ignition signals received from the combustion control unit. CONSTITUTION:When the flame detector fails to detect flames, the combustion control unit issues non-ignition signals to activate the relay X, opening the contacts X1 and X2. With this, the charging of the condenser F is interrupted and the amplifier B maintains the same temperature as the one just before non-ignition. When the temperature just before non-ignition is found higher than that just before ignition, the output from the voltage comparator C, via the contact X3, turns ON the lamp D to inidicate that the trouble with the flame detection circuit is responsible for the failure to ignite. On the other hand, when the temperature just before non-ignition is not found higher than that just before ignition, no output is outputted from said voltage comparator C and the lamp D is not turnedn ON. This enables to determine which is responsivle for the failure to ignite, trouble with the flame detection system or shortage of fuel.

Title: Fault locator for power cable
Inventor: MIYAMOTO TOSHIHARU
IPC: G01R31/08
Filed: 1993-02-10
Abstract: PURPOSE:To realize space saving and cost reduction by arranging a current sensor so that the magnetic path thereof surrounds three-phase conductors integrally thereby decreasing the number of current sensors. CONSTITUTION:A current sensor 3 is arranged while integrating a three-phase power cable 1 and a sheath bond wire 4 using insulation joint boxes 2 in a manhole A, for example. It is similarly applied to a terminal joint box of GIS and a Y-branch insulation joint box in manhole. Since a single three-phase current sensor is employed for power cable, space is saved and cost is reduced. Surge current flowing on an underground power cable is detected by current sensors arranged in the insulation joint boxes 2 or the terminal joint boxes installed at a plurality of points and then a fault is located by measuring the difference of arriving time of surge current between the current sensors 3.

Title: Polymer injection molding machine
Inventor: KUROSAKI YASUO
IPC: B29C33/38
Filed: 1995-02-10
Abstract: PURPOSE: To improve the transfer properties of a resin material without impairing high productivity of the basic merit of an injection molding and to provide a molding having uniform optical properties. CONSTITUTION: A mold wall 2 for forming at least hard transfer area of a mold cavity 1 is formed of an infrared transmitting material, and infrared rays are emitted from an external light source to the wall at the time of injection molding.
