Latest Patents

Yoshida holds a patent for a method of manufacturing color picture tubes using rotating light. This invention focuses on improving the manufacturing process by applying a photosensitive slurry on the inner surface of a face panel. The slurry is dried to form a layer, and a shadow mask is secured with a specified gap. Ultraviolet rays are then directed onto the dried slurry through a path-refracting lens, allowing for the formation of dots on the inner surface. A key improvement in this method is the inclusion of a light attenuator, which controls the exposure distribution of ultraviolet rays. This innovation ensures that the sizes of the dots at the edges of the screen remain consistent, resulting in a balanced color display across the entire picture screen.
