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.

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： In a color cathode ray tube comprising a panel with a substantially rectangular effective portion whose outside face is almost flat or slightly curved and whose inside face has a curvature in the direction of minor axis near the short sides of the portion, and a fluorescent substance screen having a substantially rectangular effective region formed on the inside face of the effective portion of the panel, the short sides in the outer circumference of the effective region of the fluorescent substance screen are projected toward the center of the effective region. This improves the flatness of images appearing on the fluorescent substance screen provided on the inside face of the effective portion in the color cathode ray tube with the outside face of the effective portion of the substantially rectangular panel being almost flat and the inside face having a curvature in the direction of minor axis at least near the short sides.

摘要： A color cathode ray tube has a shadow mask. The shadow mask is composed of an almost rectangular mask body and an almost rectangular mask frame. The mask body has an effective surface facing a fluorescent screen, a non-aperture section surrounding the effective surface, and a bent skirt section formed on the periphery of the non-aperture section. The mask frame has a sidewall section provided on the skirt section of the mask body. In the shadow mask of such a configuration, a step section having a step in the direction perpendicular to the skirt section of the mask body is formed. With this configuration, the strength with which the curved surface of the effective surface of the shadow mask is enhanced, which prevents the color purity from deteriorating due to deformation and facilitates the formation of the shadow mask.

摘要： A shadow mask has a mask body and a substantially rectangular mask frame attached to a peripheral portion of the mask body. The mask body has a substantially rectangular curved effective surface opposed to a phosphor screen formed on an inner surface of a panel. The effective surface has a number of electron beam passage apertures. The effective surface of the mask body has a curvature in a direction of the long axis, which is set within a range of about 0 to 2×10−4 (1/mm) over an area from a center of the effective surface to a middle portion of the effective surface in the direction of the long axis. A curvature at a peripheral portion in the direction of the long axis is set to be greater than that at the middle portion. A curvature on the short axis in the direction of the short axis successively increases over a distance equal to at least two thirds of a distance between the center and an effective end of the short axis.
