Title: Fluorescent lamp apparatus
Inventor: TANAKA TOSHIYA
IPC: F21V23/00
Filed: 1987-09-14
Abstract: PURPOSE: To eliminate a disconnection of a soldered part by leaving a peeled part of a bundled core wire and reducing generation of stress of the core wire, when soldering the peeled tip of the core wire to a base or a lighting circuit component, as for a covered cord covered by a core wire with plural solid wires bundled. CONSTITUTION: A covered cord 30a is formed by using a core wire 31 with plural solid wires bundled, and therefore it is essentially softer than one using a core wire of a solid wire. In addition, since a peeled part 35 of the core wire 31 comprising the bundled wires is provided between the soldered part 34 of an eyelet terminal 3a and a covering 35, the peeled part can be easily transformed. Accordingly, since the peeled part 35 provided is soft, it is easily transformed, so that the covered cord 30 a transforms by following relative rotation displacement of a headlamp circuit part 11 and a base 3. Thereby, the covering can eliminate a disconnection of the soldered part by reducing generation of stress in the core wire.

IPC: G11B7/24067
Filed: 1994-08-31
Abstract: PURPOSE: To obtain an optical information recording medium ensuring slight overwriting jitter in mark edge recording with an optical head giving a specified wavelength. CONSTITUTION: A reflecting layer 5 is made of Si and the thicknesses of a lower protective layer 2, a recording layer 3, an upper protective layer 4 and the reflecting layer 5 are regulated to 180-260nm, 10-13nm, 13-25nm and 55-65nm, respectively. The absorption factor of crystalline Si can be made higher than that of amorphous Si while maintaining large variation in reflectance between amorphous Si and crystalline Si at about 690nm wavelength and the objective optical information recording medium having a high rate of erasure and hardly increasing jitter by overwriting is obtd. Since light is hardly absorbed in the reflecting layer 5, a satisfactory amorphous mark can be formed without decelerating the cooling of the recording layer 3 after irradiation with laser light.

Title: Device for detecting life of perforating tool
Inventor: MASUMURA SACHIKO
IPC: B23B49/00
Filed: 1985-10-18
Abstract: PURPOSE:To detect the life of a perforating tool with high accuracy by comparing the actual amplitude of a load signal from the load detecting means of said perforating tool with a set reference amplitude, and outputting a tool life judging signal when said actual amplitude is the larger. CONSTITUTION:The take-in of torque is started when T seconds has elapsed after starting machining, and a standard deviation sigma is calculated from n- numbers of torque values obtained by the time immediately before the end of machining. By comparing the actual standard deviation sigma thus obtained, with a previously set reference standard deviation sigma0, when the actual standard deviation is the larger, the life of a drill 1 is considered to have come to an end and a warning signal is outputted to a warning lamp 6. Thereby, an operator can tell that the life of the drill 1 has come to an end from the on/off of the lamp 6, and replaces the drill 1. Since the life of the drill 1 is thus detected by the width of variation of torque, erroneous judgement will not occur even if there is an individual difference in the hardness of workpiece, accurately detecting the life of a drill.
