    摘要: An asbestos-free high performance clutch facing which exhibits a less decrease in the friction coefficient as well as a less wearing during long-term repeated cycles of loading at high temperatures is disclosed. The clutch facing is a disk-shaped clutch facing produced by molding a composition for a friction material with heating and under pressure, the composition comprising: 15-50 parts by weight of (I) a binder composition comprising 95-30% by weight of (a) an aromatic hydrocarbon-formaldehyde resin-modified novolak type epoxy resin, and 5-70% by weight of a cyanate ester resin consisting essentially of (b) a polyfunctional cyanate ester, or a prepolymer of the cyanate ester, or (b) and (c) a monofunctional or polyfunctional maleimide; 20-70 parts by weight of (II) a fibrous reinforcing substrate with a fiber diameter of 0.2 .mu.m or more; 2-20 parts by weight of (III) a metallic fiber substrate with a fiber diameter of 10 .mu.m or more; and 5-40 parts by weight of (IV) a friction wear regulator.

    摘要: A process is provided for the production of a base board for printed wiring. The process involves the steps of wrapping a block inorganic continuous porous material with a cloth, impregnating the wrapped block inorganic continuous porous material with a thermosetting resin under reduced pressure, curing the thermosetting resin to form a composite material, and slicing the composite material into base boards having a thickness of 0.2 to 2 mm and a thickness allowance of .+-.5 .mu.m or less, or the steps of impregnating a block inorganic continuous porous material with a thermosetting resin in an impregnation vessel under reduced pressure, taking the block inorganic continuous porous material impregnated from the impregnation vessel, substantially removing the thermosetting resin adhering to surfaces of the block inorganic continuous porous material before the thermosetting resin forms a gel, curing the remaining thermosetting resin under heat to form a composite material, and slicing the composite material into base boards having a thickness of 0.2 to 2 mm and a thickness allowance of .+-.5 .mu.m or less.

    摘要: A method and system for operating a regenerative gas turbine in which a compressed gaseous medium is saturated with steam from untreated water having impurities in a first contact chamber and then supplied to a second chamber where the mixture is washed with pure water to remove impurities. The resulting mixture is mixed with fuel and combusted to supply gas to the turbine. Exhaust gas from the turbine is supplied to two serially connected regenerators which transfer heat to the recirculating untreated and pure water.
