摘要： An improved structure for cooling a cathode ray tube apparatus for projecting color images includes a cooling medium contained in a space defined by a front panel of the cathode ray tube, a front panel or lens, and a metallic frame for transferring heat from the tube to the frame. An improvement includes an air or expansion chamber communicating with the defined cooling medium space to permit expansion of the heated cooling medium into the chamber, while preserving the distance between the front panel of the tube and the lens.

摘要： A projection type green cathode ray tube (CRT) with improved brightness despite an increase in the temperature of the faceplate, a method for manufacturing a phosphor screen adopted therein, and a projection video device which utilizes the projection type green CRT. The phosphor screen of the CRT is formed of a cerium-activated calcium sulfide phosphor which contains 0.01 to 0.3 mol% of cerium. According to the method for manufacturing the phosphor screen, the cerium-activated calcium sulfide phosphor is precipitated in a 0.3 to 5% aqueous solution of water glass based on weight. The aqueous solution does not contain barium ions. The projection video device includes the green CRT, a red CRT having a phosphor screen which is formed of an europium-activated yttrium oxide phosphor, and a blue CRT having a phosphor screen which is formed of a silver-activated zinc sulfide phosphor. Brightness of images is improved and does not substantially change over time.

摘要： A method of manufacturing storage/display two chamber tubes by providing a molded soft glass envelope with a high outer shoulder at an open end and a low inner shoulder at the same end to form a trough in-between. The trough is filled with liquid metal, having a suitable melting point, such as indium, and the metal is allowed to solidify. A metal ring bearing a membrane for separating the two chambers one from another is placed on the solidified metal with air passages provided between the ring and the trough metal. A faceplate is sealed to the outer shoulder providing a closure of the second chamber and both chambers of the tube are then evacuated through a single tubulation. Finally, the tube is heated to bake out gasses trapped in the walls of the tube and to melt the trough metal. Upon melting, the metal ring settles into the trough metal forming a hermetic seal between the two chambers.
