Title: Card image reader
Inventor: HOSOKAWA MINORU
IPC: H04N1/00
Filed: 1989-11-28
Abstract: PURPOSE:To simply find out a location of a fault such as jam caused on a carrier path by comparing passing time between two optional sensor means with a card feed speed by a drive means so as to detect a defective transmission of the card and warning a location of defect on the carrier path in voice. CONSTITUTION:When there is any discrepancy between a theoretical carrier position of a card C by a drive means 24 and an actual carrier position by sensor means 19, 20, a warning means 53 raises a warning. The arranged location of the sensor means 19, 20 causing the discrepancy of the carrier location is warned in voice as a defective location in this case. Thus, which location the fault takes place on the carrier path is simply recognized. Even when no hindrance takes place in the read of the card C, since a warning is raised due to the discrepancy between the theoretical location and the actual carrier location in this way, a delicate fault or damage of the drive system being a cause to the discrepancy is found out.

Title: Water-cooled thyristor module
Inventor: KOGA TOSHIRO
IPC: H01L23/473
Filed: 1994-12-13
Abstract: PURPOSE: To prevent dielectric breakdown of module component parts by forming water-leading grooves by notching the upper surface of a drain flange to lead leaked water collected on a module frame bottom plate from water- cooled cooling means to a drain hole. CONSTITUTION: Based on the assumption that leaked water 10 from a module component part 22 is accumulating on a module frame bottom plate 2, the leaked water 10 reaches to bottom portion of water-leading grooves 3 on a flange 1 for water drain. Then, it is discharged from the water-leading grooves 3 into a through hole 1a, then to a water-cooled module in a following stage. Accordingly, leak water 10 is discharged from the water leading channels 3 before being accumulated up to an uppermost surface of the flange 1 for drain, and then reaches to a leak water detector 23 via a water-cooled module in a lower stage. Leaked water 10 is thus rapidly detected. Thus, dielectric breakdown of module component parts due to leak water is prevented.

IPC: G05F1/56
Filed: 1992-10-24
Abstract: PURPOSE:To prevent the fluctuation of the output voltage caused by the increase of the off-leak current of a transistor which constructs a voltage regulator. CONSTITUTION:A voltage regulator consisting of a 1st transistor TR Q1 and a 1st operational amplifier OP1 is provided with a 2nd operational amplifier OP2 whose non-inverted input increases along with the increase of the output voltage VO and a 2nd TR Q2 which is electrically conductive by the increase of output of the OP2.

IPC: B24C1/00
Filed: 1989-11-29
Abstract: PURPOSE:To efficiently carry out descaling without causing surface roughing on a steel surface by projecting shots onto the Ti side of a one-side Ti clad steel sheet and then subjecting both sides of the clad steel sheet to pickling by means of a mixed acid solution.

Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To miniaturize a device using both of an IrDA and a remote controller by providing a driving circuit whose driving capability is varied according to a communication form and whose light emitting element is driven according to inputted data, thereby reducing the number of ICs. SOLUTION: In the case of IrDA communication, a mode switching circuit, which receives a mode signal from an external control circuit, generates a selector signal SL at a high level. According to this, the driving capability of the driving circuit 14 is lowered and selector 17 impresses the output signal of a light receiving element 16 to a first signal processing circuit 18 being a processing circuit for the IrDA. In addition, by switching the driving current of the circuit 14 to large or small, the driving capability of the circuit 14 is switched. On the other hand, in the case of remote controlled communication, the mode switching circuit, which receives the mode signal from the external control circuit, generates the selector signal SL at a low level.  Thus the driving capability of the driving circuit 14 is increased and a selector 17 impresses the output signal of the element 16 to a second signal processing circuit 19 being a signal processing circuit for a remote controller.
