Latest Patents
One of Duchek's latest patents is titled "Method and apparatus for direct contact printing screens on CRT." This invention discloses direct contact printing methods and apparatuses for applying screen elements to CRT faceplates. The process begins with the application of a black-surround, or grille, to the faceplate, followed by the deposition of light-emissive phosphors. The patent also details means for repeatable positioning of the screen elements, registration of the elements with each other, and maintaining their shape and size. Effective pivot axes for the collector are arranged to lie in the plane of the printing substrates.
Another significant patent is the "System for registering and assembling tension masks and CRT faceplates." This production system is designed for registering flat tension masks to screen-bearing face panels during CRT manufacturing. Both the panel and mask are supported in modules with identical registration features at loading stations. They are then alternately conveyed to an assembly station equipped with a top-mounted laser welder for welding the mask to panel rails. The system includes a lift assembly that loads the modules into the assembly station, where they are registered with the same registration elements. Cameras associated with the panel module interrogate screen location, enabling precise positioning of the mask.
