摘要： A display apparatus comprising an evacuated envelope having an interior surface and an exterior surface is disclosed. The envelope includes a faceplate having a luminescent screen on the interior surface thereof. An electron gun is disposed within a neck of the envelope for generating at least one electron beam that is directed toward the luminescent screen. A funnel connects the neck of the envelope with the faceplate. A deflection yoke is disposed around the envelope at the junction of the neck and the funnel. The yoke is attached to the envelope with an adhesive. A resistive primer coating is disposed on the envelope and forms a barrier between the yoke adhesive and the envelope. The resistive primer coating is formed from an aqueous formulation comprising a copolymer of chloroprene and methacrylic acid, a conductive filler material and at least one cross-linking agent.

摘要： A method of cleaning the neck of a funnel of a CRT during the manufacture thereof. The method includes: inserting a drain tube within the neck, wherein a gap exists between the drain tube and the neck; directing a fluid through the gap; and draining the fluid that was directed through the gap through the drain tube, whereby the fluid removes material from the neck that was applied during a prior coating process and any dirt. The drain tube is part of a cleaning apparatus that further includes a housing and a labyrinth flow controller positioned within the housing adjacent to the drain tube forming a laminar flow section whereby fluid is directed through the housing and into the tube.
