Abstract: A cathode ray tube includes a panel with an inner phosphor screen, and a funnel sealed to the panel while facing the phosphor screen. The funnel is externally mounted with a deflection yoke. A neck is sealed to the rear of the funnel while mounting an electron gun to emit electron beams therein. A shadow mask is placed within the panel. The shadow mask has a hole-formation portion with a plurality of beam-guide holes, a non-holed portion externally surrounding the hole-formation portion while being shaped with a rectangular frame, and a skirt bent from the outer periphery of the non-holed portion to the rear of the panel. The skirt has a basic etching portion half-etched at a predetermined roughness. The components of the shadow mask are integrated into one body. A welding portion is formed at the bottom of the skirt with a plurality of welding points. A mask frame is internally suspension-fitted to the panel while being welded to the skirt to support the shadow mask. The skirt of the shadow mask has a subsidiary etching portion placed between the welding portion and the basic etching portion while being half-etched at a roughness greater than the roughness of the basic etching portion.

Abstract translation: 阴极射线管包括具有内荧光屏的面板和在面向荧光屏的情况下与面板密封的漏斗。 漏斗外部安装有偏转线圈。 颈部密封到漏斗的后面，同时安装电子枪以在其中发射电子束。 荫罩放置在面板内。 荫罩具有孔形成部分，该孔形成部分具有多个光束引导孔，外部围绕孔形成部分的非孔部分，同时成形为矩形框架，以及从非易失性存储器的外周弯曲的裙部， 孔部分到面板的后部。 裙部具有以预定粗糙度半刻蚀的基本蚀刻部分。 荫罩的组件被集成到一个主体中。 焊接部分在裙部的底部形成有多个焊接点。 面罩框架内部悬挂于面板上，同时焊接到裙部以支撑荫罩。 荫罩的裙部具有放置在焊接部分和基本蚀刻部分之间的辅助蚀刻部分，同时以大于基本蚀刻部分的粗糙度的粗糙度进行半蚀刻。
