摘要： PURPOSE:To reduce leakage current to a metal plate when voltage is applied to it in a sheet heating element on which the grounded metal plate is arranged. CONSTITUTION:An insulating film arranged between a conductive sheet for heating and a metal plate is made of a plastic material with a thickness or 500mum-5mm and a dielectric constant of preferably 3.5 or less. Since leak current can be reduced with almost no reducing heat transmission characteristics, the connection number of heating elements per circuit breaker with leakage breaker can be increased.

摘要： PURPOSE:To obtain the subject material for compression molding in which the reinforcing fibers are well dispersed and which has excellent mechanical strengths. CONSTITUTION:This production process comprises mixing milled carbon fibers of a fiber length of 0.5mm or below with an aqueous dispersion containing about 0.1-10wt.% polytetrafluoroethylene (PTFE), optionally drying the resulting mixture to obtain milled carbon fibers sized with PTFE, mixing the milled carbon fiber with a PTFE molding powder in water under agitation at a high speed of 2000rpm or above and removing the water from the resulting mixture.

摘要： PURPOSE:To provide a cylindrical porous carbon molded piece keeping a uniform bulk density as a joint-free integrally molded piece. CONSTITUTION:A carbon fiber felt is impregnated with a 60% solution of a resol phenol resin (a melting point of 85 deg.C) in a methanol, dried at 120 deg.C, and cooled to 20 deg.C. This is passed through compression rolls to be formed as a compressed prepreg sheet. After the compressed prepreg sheet is wound along a gap between an inner mold and an outer mold for molding a cylindrical molded piece, this is entirely left to stand in a 150 deg.C drier. The prepreg sheet is expanded to adhere to the inner mold and the outer mold. This is further left to stand for 60min at the same temp. for thermosetting the prepreg sheet. After that, the sheet is removed from the molds, thereafter being calcined to be carbonized or graphitized. In this manner, a cylindrical porous carbon molded piece is produced.

摘要： PURPOSE:To improve the homogeneity of the cylindrical porous carbon molded product by winding a binder-impregnated fiber aggregate on an inner mold used for cylindrical molded products, covering the combination with a bag-like article, compressing the fiber aggregate under vacuum, disposing the compressed fiber aggregate in an outer mold, releasing the compression of the compressed fiber aggregate, thermally curing the fiber aggregate and subsequently calcining the molded fiber aggregate. CONSTITUTION:A felt-like fiber aggregate using carbon fibers is impregnated with a binder solution such as a phenol resin and then dried to produce a binder-impregnated fiber aggregate 2. The fiber aggregate is wound on the outer side of an inner mold 1 used for molding cylindrical molded products in a thickness larger than the distance between the outside of the inner mold 1 and the inside of the outer mold 4. The combination is covered with a bag-like article made from PP, etc., and the inner part of the bag-like article is vacuumized to compress the binder-impregnated fiber aggregate 2, thereby bringing the fiber aggregate tightly into contact with the inner mold 1 to allow the wound fiber aggregate to contract into a thickness smaller than the distance between the molds. Subsequently, the combination is disposed in the outer mold 4, and the vacuum is released to tightly bring the wound fiber aggregate into contact with the outer mold 4. The fiber aggregate is thermally cured and demolded from the inner mold 1 and the outer mold 4. The molded product is calcined at a temperature of >=1000 deg.C under vacuum for the carbonization thereof or graphitized at a temperature of >=2000 deg.C to obtain a cylindrical porous carbon molded product or a cylindrical graphitized molded product.

摘要： PURPOSE:To form the carbon fiber heat insulating material having densities of a wide range with fewer stages for working by subjecting a mixture composed of carbon fibers of a pitch system and an expandable resin to expansion molding, then to calcination. CONSTITUTION:This carbon fiber heat insulating material is formed by subjecting the mixture composed of the carbon fibers of the pitch system and the expandable resin to the expansion molding then to the calcination. Compounding of other heat resistant fillers in addition to the carbon fibers of the pitch system for the purposes of providing improvement in the strength and dimensional stability of the heat insulating material, improvement in expandability, improvement in packing workability, etc., is possible as well. Such heat resistant fillers are exemplified by, for example, carbon black, graphite, coke, pitch, alumina, inorg. or org. fiber whiskers, polyacrylonitrile carbon fibers, etc. The expandable resin may be either of powder or liquid type if the resin has good expandability and has the relatively high carbonization rate at the time of high-temp. calcination.
