Title: Semiconductor device
Inventor: SAKIMOTO MASAKAZU
IPC: H01L23/52
Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To prevent the service life of wiring from deteriorating by dissipating Joule's heat generated from the wiring effectively. SOLUTION: Heat conducting layers 11-13 composed of a material having high thermal conductivity are provided in the same layer as wiring layers 2, 4, 6. One wiring layer 2, 4, 6 is coupled thermally with the heat conducting layer 11-13 in other layer in order to dissipate heat generated therefrom through a heat dissipating body located contiguously to the heat conducting layer 11-13 in other layer on the outer surface of a semiconductor device. A heat plate formed on the upper surface of semiconductor substrate or semiconductor device is employed as the heat dissipating body. Since Joule's heat generated from the wiring layer can be discharged through thermal conduction, temperature rise of wiring can be suppressed. Consequently, service life of the wiring is prolonged and the current density can be increased.

Abstract: PURPOSE:To obtain easily a heat-shrinkable resin laminated tube having an adhesive layer good in adhesion to a metal pipe, by co-extruding a thermoplastic resin that will form an outer layer and an adhesive that will form an inner layer to be laminated, and increasing the diameter of the resulting laminated tube. CONSTITUTION:After a thermoplastic resin is melted in an extruder 1 and a hot-melt adhesive is melted in an extruder 2, they are fed to a tubular mouth piece 3. The flow beginning temperature of the hot-melt adhesive should be in the range of from the softening temperature of thermoplastic resin to the melting temperature thereof. The thermoplastic resin and the hot-melt adhesive that are fed to the tubular mouthpiece 3 are co-extruded, with the thermoplastic as an outer layer and the hot-melt adhesive as an inner layer, into a laminated tube.

IPC: G09G5/00
Filed: 1992-02-03
Abstract: PURPOSE:To reduce latch steps for adjusting the time for a synthesized parts. CONSTITUTION:In a device for synthesizing plural faces constituted of dual port memories 5-8, since the processing such as the decision of transparent color during one clock cycle read from the dual port memories does not performed at the time of the deciding the transparent colors, pixel data read from the dual port memories are requirerd to be delayed by means of latches 14, 15, 16.... Consequently, the pixel data not requiring the processing such as the decision of transparent colors requirers the latches only to be delayed until the synthesization. By delaying the clock timing read from the dual port memories concerning with the surfaces unneccesary to be processed such as the decision of tarnsparent colors, the delay operation of pixel data by the latches is eliminated. By reducing the number of latches, the area of a substrate is reduced and the generation of heat is surpressed.

Abstract: PURPOSE:To easily obtain a solar battery of high conversion efficiency by a method wherein a clear electrode containing SnO and InO is allowed to increase SnO more as it goes closer to the active layer and contain only SnO at the interface with the active layer. CONSTITUTION:The clear electrode layer 2 of the mixed body of InO and SnO is formed on a clear glass plate 1. The layer 2 is allowed to reduce the rate of InO continuously or stepwise at it goes closer to the Si active layer 3, then the rate of SnO increases, and accordingly the layer 2A at the interface between the active layer 3 is constituted of only SnO. Amorphous Si 3 and an Au electrode 4 are superposed on this layer 2. By this constitution, a hetero junction of good characteristic is formed of the layer 2A containing no InO but only SnO and the active layer 3. Since InO is contained at a large rate, the specific resistance of the layer 2 is small, accordingly the generated photocurrent flows without accompanying a large resistance loss in the layer 2, and therefore very large conversion efficiency can be obtained.
