Abstract: This invention relates to a polymer mixture which comprises an aromatic polycarbonate (A); a styrene (or styrene derivative and/or (meth)acrylate) containing polymer or copolymer and/or a styrene (or styrene derivative and/or (meth)acrylate) containing graft polymer (B); phosphorous compound(s) which are phosphate or phosphonate or oligomeric or poly-phosphate based flame-retardant(s) (C); specific inorganic additive(s) (D); and further flame retardant(s) or anti-drip agent(s) (E): and optionally, other additives.

Abstract: An electrically conductive casing for an electronic device comprising a molded article which is comprised of a fiber-reinforced plastic composition comprising carbon fiber and polyamide, said polyamide comprising semi-aromatic polyamide and aliphatic polyamide in a weight ratio of 10:90 to 90:10, wherein said semi-aromatic polyamide is a polymer of an aromatic diamine and an aliphatic dicarboxylic acid.

Abstract: Disclosed herein is a carbon fiber-reinforced carbon composite material which comprises a carbon fiber reinforcement in the form of nonwoven fabric and a matrix composed of an adhesion promoting phase of vitreous carbon and a filling phase of soft carbon or fine mosaic carbon. It has a high density, high strength, good frictional properties, and high wear resistance.

Abstract: Disclosed herein are a carbon fiber-reinforced carbon composite material composed of carbon as a matrix and carbon fiber as a reinforcement, and also a process for producing the same. The composite material is produced by coating nonwoven fabrics of carbon fiber or a blend of carbon fiber and organic fiber with a filler-containing liquid, laminating the nonwoven fabrics one over another, and subjecting the laminated nonwoven fabrics to needle punching repeatedly with a plurality of needles, thereby yielding a prepreg of three-dimensional structure, and carbonizing and calcining the thus obtained prepreg.

Abstract: Non-permeable carbonized formed bodies consisting of carbonaceous material containing 5-50 wt % of graphite and the balance of glassy carbon formed by bake-carbonization of a thermosetting resin, and a method for producing such non-permeable carbonized formed bodies comprising mixing and kneading a thermosetting resin powder, thermosetting resin liquid and graphite powder, drying, hardening and bake-carbonizing the resultant body is disclosed.

Abstract: Method for producing molded metallic honeycomb structures of high physical strength and porosity, the method comprising forming a honeycomb structure by extruding through a die a kneaded mixture of a metal powder and a binder capable of forming a supporting bone structure for the metal powder upon application of heat, and, after drying, sintering the honeycomb structure.

Abstract: The invention is concerned with a porous molding obtained by extruding a mixture containing at least one material selected from porous inorganic materials and carbonizable organic materials and at least one binder therefor in the form of threads or strings, accumulating the thready or stringy extrudates to form a mass, and then drying and sintering the accumulated mass. When the at least one material is an organic material, the sintered mass is carbonized in a non-oxidative atmosphere and then activated as usual.

Abstract: An activated carbonaceous honeycomb body is prepared by extruding a tempered mass containing a thermosetting resin such as phenol resin, drying and solidifying the green honeycomb body, preheating the same in a nonoxidizing atmosphere at a heating rate of 30.degree. C./hr or lower to a temperature between 500.degree. and 1,100.degree. C. until the hydrogen content of the resulting C-matrix has been lowered to 2% or less, and then heating the thus-preheated honeycomb body in an activating atmosphere to a temperature between 600.degree. and 1,000.degree. C. until the ratio of the total thickness of resulting activated carbon layers to that of the remaining glassy carbon layer in the thickness direction of each wall of the honeycomb body has reached a value not greater than 30. The activated carbonaceous honeycomb body exhibits good refractoriness and thermal shock proofness as well as pertains excellent strength, particularly, against compression forces.

Abstract: The invention is a process and apparatus for measurement of diffusible hydrogen within a metal, in which a metal sample is placed within an enclosed collector vessel for a predetermined time and at a predetermined temperature, and the total resultant effused gases within the collector vessel are fed to a gas chromatograph.
