摘要： A flat type indicator tube is provided with a box-like cover glass on a substrate. The cover glass forms an air tight space together with the substrate. In the space, there are provided display sections each consisting of a plurality of anode segments disposed on the substrate, grid and cathode electrodes provided above the display sections. The cover glass is comprised of a flat major section, a side wall and a flange section. The flange section comprises a flat flange contacting the substrate through glass frit and a coupling portion so shaped as to receive one end portion of the exhaust tube therein. A projection is formed on and substantially perpendicular to the inner wall of the coupling portion of the flange section. The projection is contacted and serves to restrict undesired excessive insertion of the exhaust tube into the coupling portion. The exhaust tube is hermetically fixed between the coupling portion and the substrate through glass frit.

摘要： A flat type display tube has an exhaust tube extending outward in a plane of the surface of the substrate and a plurality of current supply lead-in strips. The exhaust tube and lead-in strips extend in the same direction from a body of the display tube. The lead-in strip is bent partway in a position short of the exhaust tube and in a direction substantially vertical to the plane of the surface of the substrate.

摘要： In a flat type fluorescent character indicating tube wherein a plurality of digit indicating elements are arranged in an evacuated envelope, there is provided a getter support structure located adjacent one end of the envelope. The getter support structure includes a shield plate extending toward the inner surface of the envelope to minimize distribution of the getter film toward the location of the digit indicating elements. At least one filament is extended above the digit indicating elements and its one end is secured to the getter support structure at a location beyond the shield plate.
