Abstract:
This invention provides an arrangement for alleviating the electric charge of members apt to be electrically charged such as spacers used in an electron beam apparatus by arranging a high resistance film thereon. Particularly, the low resistance layer arranged at each of the members is covered by a high resistance film to suppress any electric discharges.

Abstract:
An ink-oozing plate for a stamp includes a stamp ink-impregnated part, which is comprised of an elastic resin-made stamp material having stamp ink-impregnable open cells. The ink-oozing plate also includes a printing face having a stamp ink-oozing part formed on the surface of the stamp material and a stamp ink-non-oozing part. The stamp ink-non-oozing part has a heat transfer substance-transferred part which is transferred by heat generation and a stamp material-molten part. The stamp material is molten by the heat generation of the heat transfer substance.
Abstract:
A process of producing an ink-oozing plate for a stamp having open cells, in which the production steps and the apparatus are simple, and an ink-oozing plate for a stamp which can provide a sharp impress image and is conveniently used, including such a method as using an exothermally fusible sheet coated with a heat-fusing substance which generates heat by irradiating with infrared rays and can penetrate into a stamp material, irradiating with infrared rays while pressing the stamp material, and coating an impress image copy with a liquid substance containing water, and thus coming to complete the process of producing the ink-oozing plate for a stamp of the present invention.
Abstract:
A knock-out type mechanical pencil which comprises a lead containing tube in which the inner and outer walls thereof are so tapered that the lead inlet thereof is larger in diameter than the opposite end thereof. The mechanical pencil further comprises a spring supporting ring interposed between the clamping ring so attached to the outer periphery of a chuck portion integrally formed with the lead guide of the lead containing tube and spiral springs to oppose with the base end of the ferrule within the outer barrel for urging the spring supporting ring to the ferrule. Thus, this mechanical pencil can eliminate the lead jams in the lead containing tube and lead breakage therein.
