摘要： The present invention relates to a method for manufacturing a metallized luminescent screen for a CRT. At least one phosphor layer is deposited (10) on an inner surface of a faceplate panel to form the luminescent screen. The panel containing the screen is then preheated (12) to a temperature equal to, or in excess of, a minimum film-forming temperature and prewetted (14) by applying water to the screen. An aqueous filming emulsion containing a copolymer of acrylates and methacrylates with an average molecular weight of from 250,000 to 500,000 is applied (16) to the prewetted screen and dried (18) to form a film layer. Next, a layer of aluminum is deposited (20) onto the film layer, and the panel, bearing the metallized screen, is sealed to a funnel by heating the panel and the funnel through a sealing cycle. The sealing cycle(22) has a first rate of temperature increase to a first temperature and a second rate of temperature increase, less than the first rate, to a second temperature. The difference between the first temperature and the second temperature is sufficient to volatilize the film layer. The second temperature is maintained (24) for a period of time sufficient to frit seal the panel to the funnel. The sealed faceplate panel and funnel are then cooled (26).
摘要翻译：本发明涉及一种用于CRT的金属化荧光屏的制造方法。将至少一个荧光体层（10）沉积在面板面板的内表面上以形成荧光屏。然后将含有筛网的面板通过将水施加到筛网而预热（12）至等于或超过最低成膜温度的温度并预润湿（14）。将含有平均分子量为25万至500,000的丙烯酸酯和甲基丙烯酸酯的共聚物的含水成膜乳剂（16）施加到预先润湿的筛网上并干燥（18）以形成膜层。接下来，将一层铝沉积（20）到薄膜层上，并且将带有金属化筛网的面板通过密封循环加热面板和漏斗而密封到漏斗。密封循环（22）具有第一温度升高到第一温度，第二温度升高速率小于第一速率升至第二温度。第一温度和第二温度之间的差异足以使薄膜层挥发。保持第二温度（24）一段足以将面板玻璃料密封到漏斗的时间。然后将密封的面板和漏斗冷却（26）。

摘要： An improved color picture tube includes an evacuated envelope having a rectangular faceplate panel. The panel includes a viewing screen on an inner surface thereof and a shadow maskframe assembly mounted therein by support means located at the four corners of the panel. The shadow mask-frame assembly includes an apertured shadow mask and a peripheral frame to which the mask is attached. The frame has two flanges arranged in an L-shaped cross-section. The support means are attached to the corners of the frame. The improvement comprises the frame being formed by four sections that are welded together at their ends. Each section includes a side of the frame and two angled corners of the frame at each end of each section. The sections overlap each other at their ends, with both of the flanges of each section in surface-to-surface contact with each other. With this construction, the frame has a single thickness along each of its sides and a double thickness at its corners, to provide more rigid attachment locations for the support means.

摘要： A liner of a deflection yoke is provided with non-threaded sleeves. A slide pin is inserted into the sleeve until a head portion of the pin comes in contact with a funnel of a cathode ray tube on which the yoke is mounted. After adjustment, a wedge is inserted into a hollow part of the pin for expanding radially the wall of the pin. Thereby, the pin is locked within the sleeve. In this way, the position of the yoke relative to the tube is secured.

摘要： The improved color picture tube includes an evacuated glass envelope having a rectangular faceplate panel. The panel includes a shadow mask assembly mounted therein by support means located at the four corner of the panel. Each support means includes a stud attached to the glass envelope. The improvement comprises the support means also including, at each of the four corners, a first spring and a second spring. Each spring is elongated, with a first portion thereof attached to the mask assembly and a second portion thereof cantilevered away from the assembly. The first spring extends peripherally in a first direction with respect to the assembly, and the second spring extends peripherally in a second direction with respect to the assembly. The first spring includes an aperture within the second portion that engages a respective stud. A section of the second portion of the second spring overlaps the second portion of the first spring. The overlapped portions of the first and second springs are attached together.
