摘要： A shadow mask includes a shadow mask body opposed to a phosphor screen, and its peripheral portion is fixed to a mask frame. The shadow mask body includes a rectangular effective portion that is formed having a large number of electron beam passage apertures. The effective portion has a major axis and a minor axis that pass through its center and extends at right angles to each other. The shadow mask comprises an auxiliary mask fixed to a region that contains the minor axis of the effective portion of the shadow mask body. The auxiliary mask is in the form of a strip that extends long in the direction of the minor axis and has a large number of electron beam passage apertures that communicate individually with the electron beam passage apertures of the effective portion.

摘要： A shadow mask is arranged to face a phosphor screen formed on an inner surface of a panel. A plurality of aperture columns are formed in parallel in the shadow mask. Each aperture column includes a plurality of apertures arranged in line at a predetermined interval. On both sides of each aperture column on the surface of the shadow mask facing the electron gun, stripe-shaped dielectric layers for acting on electron beams toward the apertures are formed respectively, and extend in substantial parallel with the aperture columns. The shadow mask is manufactured in such a manner that stripe-shaped insulating material layers are formed on the surface of a mask base material facing the electron gun, the mask base material is thereafter shaped into a predetermined shape, and the insulating material layers on the shaped mask are sintered.

摘要： A shadow body includes an effective area having minor and major axes that extend perpendicularly to each other. Each of electron beam passage apertures formed in the effective area is a communication hole that connects a larger hole opening in one surface of the effective area and a smaller hole opening in the other surface of the effective area. A joint portion between the larger and smaller holes of each electron beam passage apertures in the central portion of the effective area is situated in the thickness-direction central portion of the mask body. A joint portion between the larger and smaller holes of each electron beam passage aperture in the peripheral portion of the effective area is situated closer to the one surface side of the effective area than the thickness-direction central portion is, the larger hole being offset against the smaller hole in the direction of the major axis.

摘要： An electron gun assembly of a color cathode ray tube emits at least one electron beam having an oblong cross-sectional shape extending substantially in the horizontal direction, and emits three electron beams in a substantially non-convergent state toward the central portion of a phosphor screen. A deflection device comprises an auxiliary magnetic field generator for generating a quadrupole magnetic field component which focuses the electron beam with an oblong cross section more heavily in the horizontal direction than in the vertical direction. The auxiliary magnetic field generator is located in a given region in a tube-axis direction in which the horizontally deflecting coil is located.
