Abstract: A method of regenerating an acid gas adsorption device includes the steps of: causing an acid gas to be adsorbed to an acid gas adsorption material by supplying a gas including the acid gas to an acid gas adsorption device so that the gas is brought into contact with an acid gas adsorption layer; causing the acid gas to be desorbed from the acid gas adsorption material; removing the acid gas adsorption layer of the acid gas adsorption device, which has been subjected to the step of causing the acid gas to be adsorbed and the step of causing the acid gas to be desorbed, from a surface of a base material; and forming an acid gas adsorption layer including a porous carrier and an acid gas adsorption material on the surface of the base material from which the acid gas adsorption layer has been removed.

Abstract: An apparatus and method for preventing an interruption of electrical power to a portable electronic device, such as, for example, a call device, supplied by an internal battery when the portable electronic device is dropped or subjected to an external shock. A battery cover seals a battery compartment in which a negative battery terminal and a positive battery terminal, of a battery, are in contact with a respective compressible contact terminal and a fixed terminal. A battery fixing base plate, attached to an inner surface of the battery cover, includes a set flange that is inserted between a battery compartment wall to which one contact terminal is attached and an associated battery terminal in contact with the one contact terminal, thus providing a mechanism that prevents a longitudinal movement of the battery in the battery compartment.
