摘要： Due to a slit formed in the dead space, a cathode ray tube capable of preventing incorrect hitting of color electron beams caused by the local doming phenomenon from occurring and thus preventing displacement of colors, unevenness in colors, and deterioration of luminance from occurring is provided. The cathode ray tube comprises a shadow mask having an effective area where lines of apertures for passing electron beams are arranged and a dead space formed on both outer sides of the effective area. In the dead space, a slit extending along the lines of the apertures is formed. Accordingly, the thermal expansion of the dead space caused by a temperature increase can be reduced, and the stress applied to the aperture line of the effective area adjacent to the dead space can be suppressed. As a result, the local doming phenomenon can be prevented from occurring.

摘要： A color display tube (1) is disclosed with an improved suspension system of the color selection electrode (12). The color display tube has suspension means that have a self-locking construction. The suspension means (20) are provided with an additional flat portion (31). This plate has an aperture (32) that is shaped such that it has at least three surfaces of engagement (42, 43) for the free end portion (22) of the supporting elements (17) which are connected to the inside of the upright edge (18) of the display window (3). When the color display tube is exposed to a shock the construction of the flat portion (31) is capable of absorbing this shock without the color selection electrode (12) coming down from the supporting elements (17). The action is based on the friction between the surfaces of engagement (42) and the free end portion (22). When a force is applied in the plane (47) of the resilient element (30), the suspension means (20) slip off from their rest position and are locked by a surface of engagement (48), the preload caused by the resilient element (30) and the spring (40) will reposition the suspension means (20) to its original position. A color display tube (1) results with good positional stability of the color selection electrode (12). Further, the color selection electrode (12) can be reclaimed in case the color display tube (1) is rejected because there is no need to weld the suspension means (20) to the free end portions (22) anymore.
摘要翻译：公开了彩色显像管（1），其具有选色电极（12）的改进的悬挂系统。彩色显像管具有自锁结构的悬挂装置。悬挂装置（20）设置有附加的平坦部分（31）。该板具有孔（32），其形状使得其具有用于支撑元件（17）的自由端部（22）的至少三个接合表面（42,43），该表面连接到直立件的内部显示窗口（3）的边缘（18）。当彩色显像管暴露于冲击时，扁平部分31的结构能够吸收该冲击，而不会使选色电极（12）从支撑元件（17）下降。该作用基于接合表面（42）和自由端部分（22）之间的摩擦。当在弹性元件（30）的平面（47）中施加力时，悬挂装置（20）从其静止位置滑落并被啮合表面（48）锁定，由弹性元件（30）和弹簧（40）将悬挂装置（20）重新定位到其初始位置。彩色显像管（1）的选色电极（12）具有良好的位置稳定性。此外，在彩色显像管（1）被拒绝的情况下，可以回收选色电极（12），因为不必再将悬挂装置（20）焊接到自由端部分（22）。

摘要： A cathode ray tube capable of preventing incorrect hitting of color electron beams caused by the local doming phenomenon and the initial doming phenomenon from occurring and thus preventing displacement of colors, unevenness in colors, and deterioration of luminance from occurring is provided. The cathode ray tube includes a shadow mask made of a flat plate in which a number of apertures 2 are arranged in lines, and slits 5, 6 are formed in the line direction of the apertures 2. These slits 5, 6 have inclined faces 8, 9, 11 and 12 opposed via openings 10, 13. Due to this configuration, the displacement of apertures due to the local doming phenomenon or the initial doming phenomenon caused by the thermal expansion of the shadow mask can be suppressed. Thus, displacement of colors, unevenness in colors, and deterioration of luminance caused by incorrect hitting of electron beams can be prevented from occurring.
