Abstract:
PROBLEM TO BE SOLVED: To provide a silicone rubber composition having satisfactory pest repellency in itself to pests such as cockroaches. SOLUTION: The repellent silicone rubber composition is obtained by blending and uniformly dispersing a polyorganosiloxane base polymer, a curing agent and, optionally, various additives to prepare an oxime type liquid silicone rubber composition, and blending this composition with acrinathrin which is a pyrethroidal compound as a pest repelling component in an amount of 0.01-10 pts.wt. based on 100 pts.wt. of the silicone rubber base polymer. The repellent silicone rubber composition maintains its pest repelling effect over a prolonged period of time and does not cause problems such as yellowing. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a conductive silicone rubber composition having small variation in volume resistivity even in a semiconductive region and also having small voltage dependency of volume resistivity. SOLUTION: The conductive silicone rubber composition is prepared by adding (B) 1-150 pts.wt. of a conductive carbon black and (C) 0.05-1,000 ppm of a slightly water-soluble or water-insoluble ionic substance in which an anionic component is bis(trifluoromethanesulfonyl)imide to (A) 100 pts.wt. of heat-curable silicone rubber.

Abstract:
PROBLEM TO BE SOLVED: To generally provide a heating apparatus for providing a relatively uniform temperature distribution to a substrate in a semiconductor-processing chamber or for heating a metal or ceramic mold for press forming glass lenses. SOLUTION: The heating apparatus for regulating/controlling the surface temperature of a substrate is provided. At least a pyrolytic graphite (TPG) layer is embedded in a heater to diffuse the temperature difference of various components in the heating apparatus and provides temporal and spatial control of the surface temperature of the substrate, for a relatively uniform substrate temperature with the difference between the maximum and minimum temperature points on the substrate of less than 10°C.

Abstract:
PROBLEM TO BE SOLVED: To provide a wafer process device, equipped with structure parts adaptive to the atmosphere containing corrosive gas that is used in a semiconductor process. SOLUTION: The wafer process device has an electrical junction part, a gas supply channel, a recess, a protruding part, a mesa (trapezoidal projection), through holes such as lift pin hole, threaded hole, and blind hole or the like, connected together for corrosion resistance, and has a special structure, of which the connection part uses a filler and a binder having superior chemical resistance. The thermal expansion coefficient of the junction part is an optimized one such as approximately agrees with that of base substrate, electrode, and coating layer. In one embodyment, the filler uses a composition containing a glass ceramic material. COPYRIGHT: (C)2008,JPO&INPIT
