IPC: H04N5/04
Filed: 1982-03-15
Abstract: PURPOSE:To eliminate the generation of missing of a picture and asynchronism completely, by putting an external driving pulse signal into a video blanking period. CONSTITUTION:A horizontal oscillation circuit 11 of a video section 8 starts the oscillation at the tail ridge of a horizontal driving pulse separated at a frequency separating circuit 10, keeps the oscillation for the horizontal scanning period and the oscillation stop period is the blanking period of an output video signal.

Title: Method for forming fluorescent screen of cathode-ray tube
Inventor: TOMITA YOSHIFUMI
IPC: G03F7/28
Filed: 1981-03-27
Abstract: PURPOSE: To form a film composed of a plurality of layers by utilizing an adhesive liquid oozing out of a layer where a fluorescent screen of multilayer construction has been formed in a cathode-ray tube.  
     CONSTITUTION: The surface of the panel of a cathode-ray tube is coated through exposure with a material producing adhesion, for instance, a polymer aqueous solution mixed with salts such as diazonium salts and zinc oxide. The panel surface is dried, before being exposed to light. The zinc oxide produced as the result of photo-decomposition begins to absorb moisture, while the portion exposed becomes adhesive. When powder is given to the above portion and then  excessive powder is removed by blowing it off to it, a film having the desired  pattern is formed. If this film is left as it was, an adhesive liquid will begin to  ooze through surfaces of particles constituting the film because of a capillary  phenomenon. At this time, another kind of powder is given to the film. If blowing off airing is also subsequently given to the film, a film composed of the particles of the second powder is formed on the first film. By repeating the same  process as this until the adhesive liquid is dried, a multilayer film can be  formed.
