Abstract: A method of manufacturing a film antenna includes: a process of sticking a bonding surface of a bonding sheet to a surface of a metal thin film of a plastic film fitted with metal thin film; a process of forming the antenna circuit part by completely cutting the plastic film fitted with metal thin film in a thickness direction thereof from the bonding surface, and half-cutting the bonding sheet in a thickness direction thereof; a process of peeling away portions of the plastic film fitted with metal thin film around the antenna circuit part; a process of laminating a first flexible plastic film onto the plastic film fitted with metal thin film side; a process of peeling away the bonding sheet; and a process of laminating a second flexible plastic film onto the surface of the metal thin film.

Abstract: A long, tubular incandescent lamp has incorporated therein a filament formed by coupling light emitting segments and non-light-emitting segments alternately with each other. Each of the light emitting segments is composed of a light emitting coil and a coil-like coupling member of a larger pitch than the light emitting coil. Each of the non-light-emitting segments is composed of a bar formed to have a straight short-circuit part, bent portions at both ends thereof and supports respectively extending from the bent portions. The short-circuit part is inserted into the coil-like coupling member and these elements are then welded to each other to obtain the filament of alternately coupled light emitting and non-light-emitting segments. The composite filament is subsequently sealed in a long, tubular bulb. Thus, the resulting incandescent lamp is easily assembled, simple in structure, and highly shock resistant.
