摘要： PURPOSE:To restrain the title tube from its doming so as to improve the atmospheric pressure-resisting strength by using, as a filler, frit glass having alumina added thereto. CONSTITUTION:A metal-backed film is formed by applying aluminium vapor deposition onto the inside of tricolor phosphor strata formed on the internal surface of a panel, and then for the purpose of making this film flat and smooth a panel baking process is performed to pyrolyze and remove a resin-filmed lamina formed beforehand on the phosphor strata. Thereafter, frit glass having its welding and joining strength improved by adding alumina thereto as a filler, is used during the sealing process of mutually welding and joining a panel section and a funnel section with the frit glass. Thus, a large-sized color cathode-ray tube can be obtained with doming-restrained structure and improved atmospheric pressure-resisting strength.

摘要： PURPOSE:To adjust refractive index between the main agent and bride agent which form a bonding agent in order to prevent generation sparcle and improve picture quality by using unsaturated ester as the bride agent of bonding agent which is used for bonding a non-reflective transparent plate to the face plate portion. CONSTITUTION:The bonding agent 3' used for bonding the non-reflective transparent plate 4 to the face plate of CRT contains unsaturated polyester main chain (refractive index: 1.50) as the main agent, stylene (refractive index: 1.54) as the bridge agent and unsaturated ester which has double coupling within the molecules (refractive index: 1.45). Thereby, polymerization of only the discrete stylene is prevented, production of polystylene (refractive index: 1.55 or more) is interfared and stylene and unsaturated ester are polymerized. As a result, the refractive index of this polymer becomes about 1.504 and it is adjusted to a value near to the refractive index of 1.50 of the unsaturated polyester main chain. Therefore, difference of refractive indices within the bonding agent 3' can be eliminated, generation of sparcle generated by difference of refractive indices can be prevented and high quality picture can be obtained.

摘要： PURPOSE:To prevent any accident of inferior conduction at high voltage by forming a conductive graphite film on a metallic film formed by vapordeposition on the peripheral irregular surface of a phosphor film which is formed on the inner surface of a bulb panel and extends to the slant inner surface of the reinforced area. CONSTITUTION:A fluorescent film 2 and an aluminum film 3 are formed on a bulb 1a which has a reinforced area, the inner surface of which is oblique to the screen portion, between the screen section and the side section. Next, the area located between point (A) and point (B) is coated with a conductive graphite film 4. Since a highly conductive film can be formed by using a graphite even on the irregular phosphor surface, any accident of inferior conduction at high voltage can be prevented by the graphite film 4. The conductive film 4 may be a fine stripe and can be easily formed using a brush.

摘要： PURPOSE:To facilitate the identification of the emitted light color by coating the surface of a phosphor material with an organic coloring matter. CONSTITUTION:A phosphor material having known light color, water and an organic coloring matter are agitated then left as it is and the upper liquid is removed thereafter the residue is dried to coat the surface of the phosphor material with an organic coloring matter. Eosin Y, Congo red are used as the red light emitting phosphor material, while marakite green is used as the green light emitting phosphor material and the methylene blue is used as the blue light emitting phosphor material. Magdara red which emits the light for the ultraviolet beam, green Fluorescin, etc. may be used. At the site where using the phosphor material, the color of the light emitted from the phosphor material is identified by the color of the organic coloring matter. Consequently the identification of the phosphor color is facilitated to eliminate the erroneous usage.
