Abstract: There is provided a heat sink sheet which can secure a heat source and a heat sink such as an aluminum cooling fin to each other and is superior in heat sink performance. The heat sink sheet is achieved by adhering a pressure sensitive adhesive layer adhered to the whole or part of a surface of a silicone heat sink layer. It is desirable that the pressure sensitive adhesion layer be made of an acrylic-containing adhesive or an urethane-containing adhesive, and a heat sink filler is advantageously blended with the pressure sensitive adhesive layer.
Abstract: To realize uniform heat distribution by adhering a radiating sheet tightly to a radiating element such as a PDP glass panel, and a heat sink such as an aluminum chassis, transfer heat smoothly to the heat sink such as the aluminum, and release foams entrapped between the radiating sheet and radiating element or heat sink efficiently. The radiating sheet is composed by impregnating a radiating material selected from the group consisting of a radiating gel and a radiating grease in a radiating base material having continuous foams, and layers excellent in heat releasing properties such as a silicone gel or an luminum foil may be formed further on the radiating sheet, or cuts may be made into these layers.

Abstract: A process for producing boluses for radiotherapy, which are disposable and excellent in processability. Natural organic polymers used as gelatinization preparations are added in water not higher than 10%, and more preferably 2-5% of water in order to produce a hydro gel comprising natural organic polymers. Then, the boluses which have equivalent to human body and are inexpensive, disposable, and excellent in processability can be obtained.
