Abstract: PROBLEM TO BE SOLVED: To lessen the deviation of radiation of light to the outside and increase the luminous intensity, by fixing a built-in columnar part having a light transmissible property, radially extending from the center, in a sign body and providing light-emitting diodes at respective ends of the columnar part so as to emit luminous fluxes toward the center through the inside of the columnar part. SOLUTION: Columnar parts 27, 27 integrally connected to each other at the center in rightangled directions, are fixed to a circular holding frame 25 inscribed in a sign body 12. Lightemitting diodes 32 are fixed to respective ends of the columnar parts 27 to turn to the center of the holding frame 25.

The resin coating layer is made of a silicone resin. The resin coating layer contains conductive fine powder and silane coupling agent. The magnetite nuclide particles are produced by mixing the magnetite particles formed by, for example, a wet process with a suitable solvent (aq. PVA soln., etc.) by means of a ball mill, etc., to prepare a slurry, then spraying and granulating the slurry by means of a spray dryer and heat treating the granules in a baking furnace, such as electric furnace.

IPC: G11C19/08
Filed: 1982-03-01
Abstract: PURPOSE:To eliminate the fluctuation of ion implantation amount into magnetic films, by performing the ion implantation into magnetic films through a carbon film. CONSTITUTION:A concatenated disk-shaped pattern 13 made of chromium/gold or molybdenum for ion implantation is formed on a magnetic film 11 through a carbon film 12 as shown Fig. (a) and ion implantation is performed. After the ion implantation, etching is performed on the carbon film 11 by using an etching gas containing oxygen ion as shown Fig. (b). The etching can be performed by introducing the oxygen gas into a plasma etching device or ion milling device of normal parallel plant type. As for the etching speed of the carbon film, a speed of about 1,000Angstrom /min can be realized easily, and the carbon film can be removed selectively by means of the etching as against the gold or molybdenum film. Fjurthermore, the magnetic film at the bottom is hardly etched. Since the remaining concatenated disk-shaped carbon pattern does not give any bad influences to the magnetic film even when the carbon pattern is heat-treated, the carbon pattern can be used for the positioning of conductor patterns to be formed next by laminated formation.
