    • A gas fuel filling lid device for a vehicle using a high-pressure gas as the fuel has a fuel filling opening for filling the vehicle with the high-pressure gas fuel, a lid openably attached to the vehicle and covering the fuel filling opening, and a cap for the fuel filling opening. The filling opening cap is fitted to the inner surface of the lid and is connected to and disconnected from the fuel filling opening in operative association with opening and closing of the lid. The structure prevents the user from forgetting to close the filling opening cap and facilitates the connection and disconnection of the filling opening cap.

    • A light-emitting diode includes: a semiconductor substrate; and a layered structure, made of an AlGaInP type compound semiconductor material and provided on the semiconductor substrate. The layered structure includes: a light-emitting structure composed of a pair of cladding layers and an active layer for emitting light provided between the pair of cladding layers; and a current diffusion layer which is lattice-mismatched with the light-emitting structure. A lattice mismatch Δ a/a of the current diffusion layer with respect to the light-emitting structure defined by the following expression is −1% or smaller: Δa/a=(ad−ae)/ae where ad is a lattice constant of the current diffusion layer, and ae is a lattice constant of the light-emitting structure.
