Title: Surface treating solution composition for cathode ray tube
Inventor: NISHIZAWA SHOKO
IPC: H01J9/24
Filed: 1990-03-12
Abstract: PURPOSE:To easily improve the contrast due to improvements in both the degree of freedom and reliability in gross value control by incorporating a polyhydric alcohol into an organic solvent solution composed mainly of a hydrolyzable silicate. CONSTITUTION:A surface treating solution composition for a cathode ray tube, made by incorporating a polyhydric alcohol such as ethylene glycol into an organic solvent solution, such as an alcohol solution, composed mainly of a hydrolyzable silicate such as tetraethoxysilane. When an organic solvent except a polyhydric alcohol and water are used in the composition, irrespective of spraying conditions and the kind of solvent, a smaller amount of the composition sprayed will provide the surface of a face plate with a poor coverage; and a larger amount of the composition sprayed will cause minute irregularity in thickness among formed particle units and form a scaly film due to nonuniformity in thickness at places where particles overlap each other although the coverage will be improved. The incorporation of a polyhydric alcohol into the composition will increase the tolerance in the formation of film so that a uniform film can be formed.

Abstract: PURPOSE:To improve the system working efficiency by ejecting an erroneous form and starting the feed of the next form with no intervention of an operator as long as the error is slight. CONSTITUTION:When an error occurs, a mechanism control part 9 searches an error code table 10 to decide the type of the error. If the recovery-unable errors like a jam, a double feed, etc. are decided, the generation of such errors is informed to an external device 5.
