Abstract: PURPOSE:To show a stable antistatic effect being hard to increase its resistance value with the passage of time by containing a film stabilizing substance in an antistatic film. CONSTITUTION:An antistatic film 9 formed on the outer surface of a face plate 5 provided with a phosphor screen 8 in the inside by a solution containing alcholate of silicone as a main component is made to contain a film stabilizing substance. The antistatic film 9 formed by using an alcholate solution of silicone partially consists of an SiO2 film having silanol base and this silanol base generates dehydrating condensation reaction with the passage of time for being glassified to lose hydgoscopic action. When this is made to contain a film stabilizing substance 10, a film stabilizing substance 10 exists so as to separate the neighboring silanol base inside the antistatic film 9 to prevent reaction of the silanol base. Thereby, with the passage of time its resistance value becomes hard to be increased so that the stable antistatic effect can be shown.

Abstract: PURPOSE:To improve the heat resistance and water resistance of an electric conducting layer by constituting the electric conducting layer with a conducting element and a binder containing a specific constituent. CONSTITUTION:A metal band 6 wound on the outer periphery of side well sections of an electrification preventing film 7 and a faceplate 5 is electrically connected by an electric conducting layer 8. This conducting layer 8 is made of a conducting oxidized layer constituted of a conducting element and a binder containing at least amorphous silicone oxide or silicone hydroxide. At least one metal element is selected among aluminum, copper, nickel, carbon, silver and gold for the conducting element. The conducting layer 8 contains amorphous silicone oxide or silicone hydroxide, thus it has excellent heat resistance and water resistance. A large quantity of conducting metal is added, and it has sufficiently small resistance. The waterproof film 7 and the band 6 can be surely connected with the conducting layer 8.

Abstract: PURPOSE:To reduce the quality deterioration of an image screen, by making the average pitch of the projections and the recesses of a transparent membrane almost equal to that of a glass panel surface, and the average height of the projections and the recesses of the membrane smaller than that of the panel surface. CONSTITUTION:A transparent membrane 3 is formed in an uneven surface by the unevenness of a glass panel 1 surface. In this case, the average pitch of the recesses 31 and the projections 32 of the transparent membrane 3 is made almost equal to that of the recesses 11 and the projections 12 of the panel 1 surface, while the average height of the recesses 31 and the projections 32 of the membrane 3 is made smaller than that of the recesses and the projections 11 and 12 of the panel 1 surface. Therefore, the smallest necessary amount of the transparent membrane 3 is secured in order to make the initial quality of the image at the level of the ordinary one, the exposed membrane over the projections 12 of the panel 1 is reduced, and the membrane amount in the recesses 11 is increased. Consequently, even though the panel is brought in contact with various substances in such a condition, the rate of the hurt of the membrane 3 is reduced, since the membrane amount exposed on the projections 12 is smaller, and the deterioration of the image screen quality is decreased even for a long service time.

Abstract: PURPOSE:To prevent an electron beam from scattering, by forming an inner shield of a color picture tube in a way of installing an aluminum film, containing the specified quantity of silicon, on a surface of a soft steel plate, and forming it as a blackening film by means of heating in vacuum. CONSTITUTION:An inner shield of a color picture tube is formed in a way of installing an aluminum film, containing 0.5-15wt% of silicon, on a surface of a soft steel plate and, after it is heated in vacuum, a blackening film made up of containing at least aluminum, iron and silicon on the surface of the soft steel plate is formed there. As for a processing condition for the blackening film, heating temperature should be set to be more than 500 deg.C processing time to more than five minutes and vacuum to less than 10 mmHg, respectively. And, with this blackening film, scattering of an electron beam on the inner shield surface is prevented from occurring. Therefore, a contrast on an image plane is excellent and, what is more, owing to regulation of silicon content, improvement in an emission life characteristic is well promotable.
