Abstract: An apparatus for stripping a film according to the invention is an apparatus for stripping a film adhered to an outer surface of an article such as a CRT. The apparatus includes a stage for mounting the article with film-adhered surface of the article oriented upward, and an edge for stripping one end of the film adhered to the outer surface of the article. The apparatus further includes stripping means allowing the edge to be heated, clamp means for clamping the one end of the film stripped by stripping means, and moving means for moving the clamp means. Thus, the apparatus can quickly and securely strip the film adhered to the outer surface of the article with ease.

Abstract: A sealed battery including a safety valve made of a metal plate which can be deformed by the increase of the inner pressure of the battery, and current cutting-off means which is actuated by the deformation of the safety valve, wherein the safety valve has a safety valve projection provided at its center to project toward an electric power generating element of the battery, a disk having a central aperture in which the safety valve projection is inserted and gas apertures through which gas is passed is fixed between the safety valve and the electric power generating element, a thin metal plate to which one of the leads of the electric power generating element is connected is attached to the element side of the disk to close the central aperture, and the safety valve projection is welded to the thin metal plate through the central aperture.
