Latest Patents
Yoshifumi Tomito holds a patent for a method of forming fluorescent screens of color picture tubes. This method involves a film of photosensitive composition that consists essentially of a diazonium salt. The portions of the films that are to be deposited with phosphors are exposed to light through a color selection electrode. This process imparts a sticky property to the portions through a photoreaction and moisture in the atmosphere. Subsequently, a powder of phosphors is deposited by utilizing this sticky property. Additionally, a photosensitive binder is incorporated into the photosensitive film, which undergoes a cross-linkage reaction with the photosensitive composition, rendering the mixture insoluble in water. This innovative method enhances the efficiency and quality of color picture tubes.
