Abstract: A battery includes a power-generating element and an insulating layer. The power-generating element includes an electrode layer, a counter-electrode layer placed to face the electrode layer, and a solid electrolyte layer located between the electrode layer and the counter-electrode layer. The insulating layer includes a first insulating film that extends inward from ends of the power-generating element in a planar view of a principal surface of the power-generating element and a second insulating film that covers a side surface of the power-generating element and that is continuous with ends of the first insulating film. The second insulating film is thinner than the first insulating film.

Abstract: The present invention lies in a flame-retardant rubber composition comprising, as essential components, a synthetic rubber (a component A), a flame-retardant (a component B), sulfur (a component C) and a polyfunctional monomer la component D), wherein an amount of the component B is 10 to 200 parts by masse an amount of the component C is 0.1 to 15 parts by mass and an amount of the component D is 3 to 30 parts by mass, all relative to 100 parts by mass of the component A. It is a technical task of the present invention to provide a flame-retardant rubber composition which has excellent flame retardancy and can give a fully satisfactory mechanical strength (particularly, tensile strength at break) even when subjected to steam cure generally regarded to be difficult to impart a strength.

Abstract: Disclosed herein is a portable digital communication device usable as a gaming device and a personal digital assistant. The device comprises a body housing, a center sliding housing for opening or closing a top surface of the body housing while being continuously opposite to the top surface of the body housing, and at least one side sliding housing attached to a side surface of the body housing and adapted to slide while being continuously opposite to the side surface of the body housing. The side sliding housing is arranged in parallel with the center sliding housing.

Abstract: A flame retardant rubber composition includes (A) an ethylene/?-olefin random copolymer, (B) an unsaturated nitrile/conjugated diene rubber, and (D) surface-treated natural magnesium hydroxide or includes (A) an ethylene/?-olefin random copolymer, (B) an unsaturated nitrile/conjugated diene rubber, (C) a hydrogenated diene polymer, and (D) surface-treated natural magnesium hydroxide. Since the rubber composition and rubber product have good flame retardance, weather resistance, and oil resistance, as well as excellent mechanical characteristics, they are useful for various applications such as a roll, belt, and sealing material for copying machines, an electric wire coating material, and hoses.

Abstract: A mobile telephone includes a body, a display, and a keypad. The keypad has a plurality of individual numeral keys assigned to individual numerals and may be rotated with respect to the body. In this way it is possible for the presentation of information on the display to remain in a fixed orientation with respect to a user while the body is rotated about the display so that the mobile telephone can be converted from right-handed to left-handed use or the display can be moved from a first orientation to a second orientation.
