摘要： PURPOSE:To obtain the light-shielding pattern excellent in adhesion to a substrate, weatherability of the coating film and light shielding property by forming the pattern with a specified grain group of the substance having a layer lattice structure. CONSTITUTION:A light-shielding pattern layer 2 formed on a transparent substrate 1 consists of a grain group of the substance having a layer lattice structure. The diameter of the light-shielding grain is controlled to =2 kinds of the substances is used, and the substance can be combined with pigment or dye.

摘要： PURPOSE:To reduce the value of a spark current by forming a conductive inner film which is formed in the inner surface of a tube for connecting the portion between a high tension conductor and the contact of an electron gun in which the resistivity and the surface roughness of the film are limited over the characteristic value. CONSTITUTION:A high tension voltage is applied to an electron gun 7 mounted within the neck portion 1 of a cathode-ray tube from a high tension conductor 4 through a conductive film 5 which is provided in the inner surface of a cone portion 2. At this time, the resistivity of the film 5 is formed to be over 0.2OMEGA.cm, and the surface roughness of the film 5 is formed to be over 6mu, and the resistance value between the high tension conductor 4 and the electron gun 7 is formed to be 2-100KOMEGA. And by limiting the surface roughness, the evaporating film of metal barium such as barium getter and the like is made to have discontinuity property and thus to prevent the resistance of the film 5 from lowering, and further by limiting the resistivity, a spark current is restrained under about 200A. Accordingly, it is possible to prevent obstacles accompanied by the spark without making the film 5 high resistance.

摘要： PURPOSE:To provide the titled paint composed of graphite, a metallic oxide, a surface-treating agent and water glass at specific ratios, containing a specific amount of graphite component having a specific particle diameter, giving low spark current value, and effective to prevent the troubles with spark. CONSTITUTION:(A) Graphite powder is mixed with (B) a metallic oxide, preferably titanium dioxide powder and (C) a surface-treatment agent, preferably colloidal silicon dioxide in water, and the mixture is granulated e.g. by spray- drying to obtain composite granules. The granules are compounded with (D) elemental graphite powder containing >=18% powder having particle diameter of 1mu and (E) water glass at a solid weight ratios (A+D):B:C:D of (10-22):(30-50):(2-9):(25-42), and the mixture is dispersed in water to obtain the objective paint. The paint forms a coating film having a specific resistance of >=0.2OMEGA.cm and a surface roughness of >=6mu, and suppresses the generation of spark current of >=200A.
