Title: Device to support pressure-welded semiconductor element
Inventor: SHIMIZU NAOHIRO
IPC: H01L29/74
Filed: 1995-01-19
Abstract: PURPOSE: To prevent the centers of electrodes on a semiconductor element from deviating from the center of a support electrode and to prevent the surfaces of the electrodes on the element and the surface of the support electrode from rubbing with each other by a method wherein a tapered insulating ring is fitted in a tapered insulating holding cylinder. CONSTITUTION: When an insulating ring 24 provided on the outer peripheral surface of the metal electrode 9 on one side of metal electrodes 9 and 8 and an insulating holding cylinder 23 provided on the outer peripheral surface of the other metal electrode 8 are fitted together by one pair of tapered surfaces of the ring 24 and the cylinder 23 in opposition to each other, the centers of the tapered axes coincide with each other. As a result, the centers of the electrodes 8 and 9, which are pressure-welded, coincide with each other, the centers or outer peripheral edges of these electrodes are used as guide jigs and a support electrode 7 and a semiconductor element are arranged, whereby the centers of these pressure-welded electrodes coincide with each other.  Moreover, forces in the directions horizontal to the surfaces of the electrodes, which are applied from the outside of a semiconductor device, are received by the one pair of the tapered surfaces of the ring 24 and the cylinder 23 and are absorbed. Accordingly, the thermal breakdown of the element, which is caused by the uneven pressure, is prevented.

Abstract: PROBLEM TO BE SOLVED: To eliminate the need of the switching valve of thermal medium and to improve long term reliability by transferring repeatedly the cells which are connected each other and filled with hydrogen absorbing alloys between a hydrogen driving part and a cold heat outputting part. SOLUTION: Cells S provided with upper row chambers S1, middle row chambers S2 and lower row chambers S3 each of which being connected to the other by a hydrogen path S4 and being filled with hydrogen absorbing alloy are used. The hydrogen absorbing type refrigerator is provided with a hydrogen driving part α that transfers the hydrogen inside the upper row chambers S1 into the lower row chambers S3, a first cold heat outputting part β that transfers the transferred hydrogen to the middle row chambers S2 and a second cold heat outputting part γ that transfers the transferred hydrogen to the upper row chambers S1.  The hydrogen driving part α is provided with a heating region α1 that supplies hot water contacting the upper row chamber S1, a middle row pressurizing region α2 that is supplied pressurized water contacting the middle row chamber S2 and a lower row heat radiating region α3 that receives heat radiating water contacting the lower row chamber S3. As the kind of the heat radiating media can be changed by transferring the hydrogen absorbing alloys themselves by the move of the cells, the switching valve is not necessary.

The gas introduction paths 4 for the burner 3 are supplied with the combustion gases 5 separately in each component. The combustion gases 5 form the flame 6 at the tip of the burner, so the surface of the rod 2 and the inner wall face of the pipe 1 are heated. Consequently, remaining flaws on the inner wall face of the pipe 1 and on the surface of the rod 2 are melted and made smooth. The burner 3 is slowly dropped from the upper side of the pipe 1 to the bottom at a specific speed, so the inner wall face of the pipe 1 and the surface of the rod 2 are totally and uniformly polished by the flame. Then, the pipe 1 is rapidly heated from the outer periphery strongly, and fused to the rod 2 and integrated.

Title: Method for suppressing generation of image blurring of electrophotographic sensitive body consisting of hydrogenated amorphous silicon
Inventor: FURUYA YUJI
IPC: G03G15/16
Filed: 1989-02-03
Abstract: PURPOSE:To allow the release, suction and removal of an active residual gas in a short period of time before the stop of a power source by inserting a tape-shaped shutter between a charger and a drum to increase the distance between the corotron charger and the drum. CONSTITUTION:The corona charger 1 and a transfer device 7 make turning motion around respective centers 2 and 8 of rotation while printing with printing paper is finished and the paper does not remain in paper feed tractor 6. The fall of the activated residual gas in a corotron casing is eventually prevented only in the specific region of the cylindrical shaft of the amorphous silicon drum 3 in a non-rotating state. The active gas in the corotron casing remaining to close the case upon ending of the printed image forming action is rapidly released and is discharged and diffused and, therefore, the direct fall of the active gas onto the amorphous silicon drum is decreased and the cause for the generation of image blurring which arises from the degradation in the printing life of the drum is suppressed.
