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： 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.

摘要： A color-cathode ray tube having a shadow mask with improved aperture arrays. The aperture arrays are spaced at appropriate intervals and are curved to suppress local doming of the effective part of the shadow mask and to prevent electron-beam mislanding from occurring on a phosphor screen. The distance between any two adjacent apertures is expressed as: PH(N)=A+BN.sup.2 +CN.sup.4, where PH(N) is the distance between the (N-1)th and Nth arrays and A, B, and C are fourth-degree functions of a Y-coordinate. The apertures along a long side of the effective part of the shadow mask in a section extending for one-fourth of a width of the effective part of the shadow mask from a short side of the effective part of the shadow mask are inclined in an opposite direction to the apertures within the section and located one-third of a height of the effective part of the shadow mask from the long side.

摘要： A color cathode ray tube has a substantially rectangular shadow mask in which a plurality of slit type aperture arrays are aligned in the direction of the major axis of an effective region defined by a curved surface opposing a phosphor screen formed on the inner surface, defined by a concave curved surface, of the effective region of a panel. Each slit type aperture array is obtained by arranging a plurality of slit type apertures in an array in the direction of the minor axis of the effective region of the shadow mask. In this color cathode ray tube, the difference between the array interval of the slit type aperture arrays at a peripheral portion on the long side of the shadow mask and the array interval of the slit type aperture arrays on the major axis is a maximum value within a distance range of 0.4 h to 0.9 h (h is 1/2 the length of the effective region of the shadow mask in the direction of the major axis) from the minor axis, and the array interval of the slit type aperture arrays at the end of the major axis is larger than that of the slit type aperture arrays at a corner. Thus, local doming of the shadow mask can be suppressed.

摘要： A face panel (12) constituting a part of a vacuum envelope (20) has a substantially rectangular effective area (10), the inner surface of which is formed with a phosphor screen (14). The effective area has a long axis (X) extending in the horizontal direction and a short axis (Y) extending in the vertical direction. The outer surface of the effective area is cylindrically curved with an infinitely large radius of curvature along the long axis and a predetermined radius of curvature along the short axis. The vacuum envelope has arranged therein a shadow mask (15) in opposed relation to the phosphor screen. A mask body of the shadow mask has a substantially rectangular effective surface cylindrically curved with an infinitely large radius of curvature along the long axis and a predetermined radius of curvature along the short axis thereof. In manufacturing the shadow mask, a flat mask is subjected to a plastic deformation into a cylindrical shape curved along the short axis and then subjected to an elastic deformation in such a manner that the radius of curvature thereof is larger than at the time of plastic deformation. The mask body thus formed by elastic deformation is fixed to a rectangular frame.

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.

A phosphor screen is formed on the inner surface of the face plate, and a shadow mask is arranged to oppose the phosphor screen. The effective area is formed such that, in an area of the effective area which is away from the center of the effective area by 1/2 or more of a distance between the center of the effective area and an axial end portion of the effective area in the major axis, a difference between the thickness of the face plate at a point which is on the minor axis and located away from the center of the effective area by a predetermined distance and the thickness of the face plate at a point which is on the diagonal axis and located away from the center of the effective area by the predetermined distance is smaller than a difference between the thickness of the face plate at the point on the diagonal axis and the thickness of the face plate at a point which is on the major axis and located away from the center of the effective area by the predetermined distance.
