Filed: 1990-04-26
Abstract: PURPOSE:To prevent stored data and a memory or the like from being degraded and destroyed by discharging static electricity by providing a conducting means near the ground terminal of a connector so as to electrically connect the ground terminal and a casing. CONSTITUTION:Near a ground terminal 27a of a connector 27 of a frame 24 fixing a printed circuit board 23, a through hole 24a is formed and a coil spring 28 composed of a conductor is housed. By the spring 28, a ground line 23a of the circuit board 23 and a panel 26 are electrically connected.

Filed: 1985-05-21
Abstract: PURPOSE:To ensure the successful employment of a thin blade in a chip- segmenting process by a method wherein preliminary cutting grooves are formed, prior to the cutting, in locations in the rear of a platform corresponding to wafer cutting margins. CONSTITUTION:A wafer 11 is caused to contact a platform 12 and adjustment is made so as to position the cutting margins 15 of the wafer 11 on the preliminary cutting grooves 16 of the platform 12. A blade 17 is activated and cuts the wafer 11 into elements along the cutting margins 15 and the bottoms of the preliminary cutting grooves 16. The cutting-off by the blade 17 is accomplished quite easily even when the plate 12 is made of glass pane or metal sheet because only the bottoms of the premilinary cutting grooves 16 are to be removed for the segmentation of the platform 12. The blade 17 may be thinner and the cutting margins 15 may be narrower, which contributes to the improvement of the yield.

Title: Glow plug for use in diesel engine
Inventor: KOYAMA TAIJI
IPC: F02B3/06
Filed: 1986-05-13
Abstract: PURPOSE:To prevent a heating unit coil from disconnecting due to an excessive temperature rise by providing a cover made of a heat resisting metal on the outer peripheral surface other than the tip end part in which a heating unit is embedded. CONSTITUTION:A rush coil 4 which is a heating unit having a small resistance temperature coefficient is electrically connected to a sheath 1 on the tip end side thereof. A brake coil 5 which is a resistor having a large resistance temperature is connected to an electrode rod 3 on the rear end side of the sheath 1. In a case where combustion products such as carbon and the like clog a clearance between a glow plug and a port, a heat resisting air layer exists because a cover 7 made of a heat-resisting metal exists on the outside of the sheath 1. Hence, heat conduction is lowered, and a brake coil 5 is not cooled at the time of power supply. Consequently, no excessively large current flows through the rush coil 4 which is a heating unit, and it prevent disconnection of the coil.
