摘要:
A communication device includes a communication circuit mounted on a printed substrate and having a heat generating element; a shield casing covering the communication circuit and shielding electromagnetic waves; a housing accommodating the shield casing and the printed substrate; a heat diffusing member mounted along an inner wall of the shield casing diffusing heat in a planar direction; and a heat insulating layer disposed between the shield casing and an inner wall of the housing.

The present invention provides a process for producing a precursor fiber which can provide a carbon fiber having high strength and high elastic modulus. The process of the present invention comprises a step where an aqueous solution of amphoteric molecule is prepared; a step where carbon nanotube is added to the aqueous solution of the amphoteric molecule so that the carbon nanotube is dispersed therein to prepare a dispersion of carbon nanotube; a step where the carbon nanotube dispersion is mixed with a polyacrylonitrile polymer and rhodanate or zinc chloride to prepare a spinning dope; a step where a coagulated yarn is prepared from the spinning dope by a wet or dry-wet spinning method; and a step where the coagulated yarn is drawn to give a precursor fiber for carbon fiber.

A method of the invention can produce a fiber-reinforced thermoplastic resin foamed product having less unevenness in a thickness of a surface layer and excellent mechanical strength. In the method, a fiber-reinforced thermoplastic resin sheet is continuously shaped into a hollow member, and a foaming resin composition containing a thermoplastic resin and a foaming agent is supplied into an interior of the obtained hollow member. The foaming agent is foamed so that the hollow member is shaped into a desired form by the foaming pressure.
