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： In a color cathode ray tube in which the external surface of an effective portion of a panel has a flat surface or a slight curvature, the shadow mask is set such that the layout distance between electron beam through hole array near the long side of an effective surface of the shadow mask is larger in the vicinity of the short axis than the layout distance at the center of the effective surface. Further, the layout distance becomes gradually smaller in direction away from the short axis, and thereafter, the layout distance changes to an increase. In the vicinity of the short side of the effective surface, the layout distance becomes equal to or larger than the layout distance near the short axis. Therefore, the curvature of the shadow mask and the electron beam through hole array are set in proper condition, and mislanding of beam landing due to deformation or oscillation of the shadow mask can be reduced. At the same time, howling of the phosphor screen can be minimized.
摘要翻译：在面板的有效部分的外表面具有平坦表面或略微曲率的彩色阴极射线管中，荫罩被设置为使得电子束通孔阵列在长边附近的布局距离有效荫罩的表面在短轴附近比在有效表面中心的布局距离更大。此外，布局距离在远离短轴的方向上逐渐变小，此后，布局距离变为增加。在有效表面的短边附近，布局距离等于或大于短轴附近的布局距离。因此，阴影掩模和电子束通孔阵列的曲率被设定在适当的条件下，并且可以减小由于荫罩的变形或振动引起的束着色的误着地。同时，荧光屏的啸声可以最小化。

摘要： A shadow mask of a color cathode-ray tube has a substantially rectangular mask main body and a substantially rectangular mask frame fixed to a skirt portion of the mask main body. The mask main body has a curved effective surface formed with a large number of electron-beam passage apertures and opposing the phosphor screen, a non-aperture portion surrounding the outer periphery of this effective surface, and a skirt portion formed in a bent on the outer periphery of the non-aperture portion. The mask main body has a long axis extending in a horizontal direction and crossing with a tube axis, and a short axis extending in a vertical direction and crossing with both the tube axis and the long axis. The effective surface and the non-aperture portion of the mask main body are formed in a curved surface having a radius of curvature in the short axis direction. At each long side of the mask main body, each end portion of the short axis of the effective surface and the non-aperture portion is recessed from any other adjacent part, in a direction leaving from the phosphor screen along the tube axis. The radius of curvature in a short axis direction near the short axis of the effective surface and the non-aperture portion of the mask main body is smaller than the radius of curvature in the short axis direction at other parts.
