摘要： An improved shielding means, for inhibiting the formation of electrical leakage between the stem leads of an electron discharge device, is a substantially infundibular shaped member formed for umbrella-fashion-attachment to an individual lead to effect better shielding of the bead area surrounding the lead. A hollow conic section, extending below a tube-like attachment portion, has an annular basal-oriented projecting portion with a peripheral downturned portion therearound. The integral shaping of the downturned portion with the projection provides beneficial structural reinforcement and rigidity to the structure and effects improved shielding characteristics.

摘要： A shielding means for inhibiting the formation of electrical leakage between the stem leads of an electron discharge device, is a substantially infundibular shaped member formed for umbrella-fashion-attachment to an individual lead to effect better shielding of the bead area surrounding the lead. A hollow conic section, extending below a tube-like attachment portion, has an annular basal-oriented projecting portion with a peripheral upward turned portion therearound. The integral shaping of the upward turned portion with the contiguous projecting portion provides beneficial structural reinforcement and rigidity to the structure.

摘要： A shadow mask for a color cathode ray tube has a rectangular, relatively rigid, lightweight frame with an inwardly extending flange having attached thereto a circumferential side wall having a constant height. A foraminated relatively fragile face with a solid skirt portion having a portion thereof formed to provide a rectangular peripheral wall with four sides extending from the face is attached to the frame. Attachment is by means of welds between the peripheral skirt wall and the side wall of the frame. The four sides of the peripheral wall have a planar termination whereby the height of any one of the side walls is continuously variable when measured from adjacent points of the termination to the curved face. This construction provides a shadow mask having increased tolerance to permanent deformation caused by heat generated by impingement of an electron beam in a confined area for extended periods of time.
摘要翻译：用于彩色阴极射线管的荫罩具有矩形的，相对刚性的轻质框架，其具有向内延伸的凸缘，其附接有具有恒定高度的周向侧壁。具有形成有一部分形成为提供具有从面部延伸的四个侧面的矩形周壁的实心裙部的被折叠的相对脆弱的面附接到框架。附件是借助于外围裙壁与框架侧壁之间的焊接。周壁的四个侧面具有平面终端，由此当从终端的相邻点到弯曲面测量时，任何一个侧壁的高度是连续可变的。这种结构提供了一种阴影掩模，其具有增加的对永久变形的容忍度，所述永久变形是由电子束在受限区域内长时间的冲击而产生的热引起的。
