Abstract: An electrically-conductive member having sufficient corrosion resistivity even when the electrically-conductive member is exposed to high potential environment and a method of manufacturing the electrically-conductive member are offered. An electrically-conductive member is obtained by a mist CVD method, by forming a metal oxide film on a base member of a separator, and the electrically-conductive member has an active potential range and a passive potential range in an anode polarization curve that is measured in a sulfuric acid aqueous solution having a sulfuric acid concentration that is 5.0×10?4 mol/dm3 at pH3 and having a temperature of 25° C., an anode current density that is 1×10?7 A/cm2 or less in the passive potential range, and the passive potential range reaching to an electric potential that is 1V.

Abstract: There is provided a metallic glass component with its surface layer having both durability of a film and chromatic color properties, and a method for forming the surface layer. Surface active treatment is performed wherein the surface of the metallic glass component is reacted with a mixed aqueous solution of nitric acid and hydrofluoric acid to remove an oxide film and to provide an anchor bond shape on the surface of a metallic glass component, and electroplating or electroless plating is then performed, to form a plating film on the surface of the metallic glass component. It is thereby possible to form a surface layer of a metallic glass which has both durability and a chromatic color.
Abstract: A coil spring is held in a compressed state between a forward end side of an elastic member compartment of a temple and a working face of a cover. A plate spring which is folded in two is held in a concave part of the cover so that a side closer to a base end portion of the temple is open, with one of two open forward ends of the plate spring engaged with a step on a bottom surface of the elastic member compartment for preventing the cover from being slid toward the base end portion of the temple and slipping off. An outer end surface on a base end portion side of the cover is in contact with a forward end surface of a rim in a normal use position. The cover is pushed by the forward end surface of the rim when the temple is further spread beyond the normal use position, to be slid toward the forward end along a guide member of the temple while compressing the coil spring against its spring force.
