摘要： A shadow mask includes a substantially rectangular effective region formed having a number of electron beam passage apertures and opposed to a phosphor screen and a substantially rectangular skirt portion provided around the effective region and extending in the direction of a tube axis. The skirt portion has a pair of long sides extending substantially parallel to a major axis and a pair of short sides extending substantially parallel to a minor axis, the long and short sides being welded to the inner surface of a substantially rectangular mask frame. A distance a from an extending end of the skirt portion on each long side to the weld spot is longer than a distance b from an extending end of the skirt portion on each short side to the weld spot.

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： The thickness of a face panel is greater at a peripheral edge portion than at a center portion. At the inner surface of the face panel, a curvature radius in a short axis direction on a long axis is set to decrease from the center of the face panel toward a long axis end and, with L representing a distance from the center of the face panel to the long axis end, has a minimal value at a position spaced from the center of the face panel more toward the long axis end than L/2. A phosphor screen on the face panel has phosphor layers and non-emitting black layers and a percentage of the non-emitting black layers per unit area at least in the neighborhood of a diagonal axis end of the face panel is equal to or smaller than that at the center portion of the face panel.

摘要： The outer surface of a panel effective section of a vacuum envelope is substantially flattened. A phosphor screen is formed on the inner surface of the effective section and includes stripe-shaped phosphor layers and light absorption layers arranged in parallel. The panel effective section is formed such that a corner portion is 8 mm to 15 mm thicker than the central portion and the transmittance of the central portion is set at 40% to 60%. The phosphor screen is formed such that the ratio of the width of a light absorption layer to the pitch of phosphor layers in the central portion of the panel effective section is larger than or equal to that in the peripheral portion thereof. A shadow mask is opposed to the phosphor screen and has a mask body in which a number of electron beam passage apertures are formed. The pitch of apertures formed in the peripheral portion of the mask body is 1.3 to 1.4 times as large as that of apertures formed in the central portion thereof.

摘要： A panel is provided with a substantially rectangular effective portion that has a substantially flat outer surface, and a phosphor screen is formed on the inner surface of the effective portion. A shadow mask that is opposed to the phosphor screen includes a substantially rectangular mask body formed having a large number of electron beam holes and a mask frame supporting the peripheral edge portion of the mask body. The interval between the electron beam holes in the direction of the major axis of the mask body increases from the center of the mask body toward the major axis end so that the rate of change of the interval has a maximum value in the region between the center of the mask body and the major axis end.

The main body 34 has a main surface portion 31 where a number of electron beam apertures are formed, and a skirt portion 33 provided around the main surface portion with a non-aperture portion 32 interposed between the skirt portion and the main surface portion. A plurality of rectangular openings 38a extending in the long axis direction (or X-direction) of the mask body are formed at the skirt portion. Concave portions 47 extending in the long axis direction (X-direction) of the mask body are formed at the non-aperture portion. The openings and concave portions are provided within a range of about ¼ of the length W of the mask body in the long axis direction, with respect to a center of the range defined at a position distant from the short axis Y by about ⅓ of the length W of the long axis direction of the mask body.
