Abstract: PURPOSE:To relieve stress due to atmospheric pressure at longer edges by allowing the force acting on a glass envelope in the region from the center of each longer edge to the center of each shorter edge to have No.1 max. value at least between the diagonal part and the center on the longer edge side. CONSTITUTION:Each diagonal part 11 of a glass envelope is not formed in a curvature having a single radius, but divided into two parts, i.e. No.1 corner 14 and No.2 corner 13. The No.1 corner 14 is situated between the center of a shorter edge 10 and the diagonal part 11, while the No.2 corner 13 positioned between the center of longer edge 9 and the diagonal part 11. According to this constitution, the fastening force generated by a metal band 2, which causes concentration in one place of the diagonal part in conventional arrangement, will be dispersed into two, i.e. a force f22 16 applied to the No.1 corner 14 and a force f21 15 acting on the No.2 corner 13, which increases the force applied particularly to the longer edge 9. This relieves the stress likely to be generated at longer edges 9 of a glass envelope.

Abstract: PURPOSE:To easily obtain the uniform reflection preventive effect by gradually changing the thickness of a single-layer film so as to make it largest near the center section of a face plate and thin at the peripheral section. CONSTITUTION:A fluorescent layer 10 is formed on the inner side of a face plate 9, and the observer observes pictures displayed on this portion. In addition, a reflection preventing film 8 is formed on the outer surface of the face plate 9. This reflection preventing film is made of a material having a refraction factor lower than the refraction factor 1.52-1.54 of the face plate glass, and its thickness is gradually changed so as to be made thick at the center section of the face plate and thin at the peripheral section. The thick portion of the film at the center section may be adjusted to 0.22/nmum or less and the thin portion at the peripheral section to 0.04/nmum or more. Accordingly, the desired reflection preventive effect can be obtained at any point on the face plate 9.

Abstract: PURPOSE:To set an increase in weight of an envelope down to the minimum as well as to make such a cathode-ray rube that is excellent in mechanical strength securable, by selecting the thickness of glass in a skirt part so properly to that of a face panel, in case of the cathode-ray tube that is very good in the flatness of a face plate and very large in a deflecting angle. CONSTITUTION:Height of a first envelope 4 is standardized with the diagonal effective diameter of a screen, and when the value is set down to K1, this K1 is expressed wit diagonal effective diameter [mm] / envelope height [mm]. If this K1 value exceeds 8, the vacuum stress valve of a seal edge part (an arrow in illustration) exceeds 1000PSI as well, therefore reinforcement by an increment of glass thickness becomes necessitated. The glass thickness of the seal edge part is standardized with the glass thickness of the central part of a face plate 2, and when the value is set down to K2, this K2 is expressed with seal edge part thickness [mm] / face plate thickness [mm]. When the K1 value is more than 8, the K2 is set to at least more than 1.3, whereby an increment in the glass thickness of the whole envelope is set to the minimum, thus such a CRT envelope that is excellent in mechanical strength can be constituted.

Abstract: PURPOSE:To secure and seal the electron gun section highly accurately in the neck section by coupling the shadowmask section and the electron gun section in color picture tube through coupling elements composed of linear metal. CONSTITUTION:At least four coupling elements 22 made of linear metallic member are arranged between the shadowmask sections 7, 11-14 and an electron gun section 5 of color picture tube where one ends are welded to the final electrode of the electron gun 5 or a convercup 16 while the other ends are welded to a terrestrial magnetism shield 14 at the shadowmask section. Then the shadowmask 7, the frame 11, the terrestrial magnetism shield 14, coupling elements 22 and the electron gun 5 are assembled into integral structure. Consequently, the electron gun 5 can be secured with quite high accuracy to reduce the landing error of each tube and the fluctuation of convergence error upon assembling.

Abstract: PURPOSE:To achieve good contrast through reduction of brightness at dark portion while to suppress degradation of color purity and to improve the emission life by forming a darkened portion composed of at least A1, Fe, Si onto at least one surface of metallic member in tube while making the content of Si near the surface of said darkened portion higher than 1.5 wt%. CONSTITUTION:An inner shield 6 is arranged while extending from the shadowmask structure along the inner face of funnel 2 to the electron gun structure 7. A darkened portion 11 is formed on the surface of metallic member in tube mainly composed of Fe such as the shadowmask structure 10 or the inner shield 6. In order to form the darkened portion 11, the surface of basic soft steel plate is washed with acid then cold rolled and fused aluminum galvanization is executed. The fused aluminum galvanization thickness will be 10-20mum. Then, in order to achieve predetermined thickness, it is cold rolled again then softened and annealed and pressed into specific shape thereafter thermally processed under reductive environment such as hydrogen environment or vacuum.
