摘要:
There are provided two substrates 11, 12 disposed in opposite to each other with a gap and a vacuum sealing portion 31 which seals predetermined positions of the substrates and defines a sealed space between the two substrates. The vacuum sealing portion 31 has a sealing material 32 filled along a predetermined position. The sealing material includes at least one type of active metal in a base material that includes Su or at least one type of melting point lowering element of Pb, In, Bi, Zn, Ag, Au, or Cu in Sn.

On the peripheral edge of a front side substrate (11) of an FED, a rectangular frame shaped sealing surface (11a) is formed for sealing a sidewall. On the sealing surface (11a), an indium layer (32) is formed through a base layer (31). At the four corners of the indium layer (32), an electrode (34) for applying an electric current is connected. The indium layer (32) is formed to have a width gradually decreasing from substantially the center of each side of the sealing surface (11a) to adjacent corners.

Das Verfahren zur Herstellung einer vakuumdichten Verbindung zwischen einem keramischen Behältnis und einer metallischen Durchführung basiert darauf, daß ein offenes Molybdänrohr in die Öffnung des keramischen Behältnisses direkt eingesintert wird. Anschließend wird die metallische Durchführung in das offene Molybdänrohr eingeführt. Das Molybdänrohr und die metallische Durchführung werden am äußeren Ende des Molybdänrohrs miteinander verschweißt.

Bei einer vakuumdichten Bildwiedergabevorrichtung mit einer ebenen Frontscheibe (5) aus Glas und einer metallischen Wanne (1) mit einem nach außen gewölbten Boden und einem umlaufenden Flansch (3) als Rückseite ist der Flansch (3) mit einem Ansatz (4) versehen. Auf dem Flansch (3) liegt die Frontscheibe (5) auf und ihre schmalen Seiten (6) werden von dem Ansatz (4) umfaßt. Zwischen diesen schmalen Seiten (6) der Frontscheibe (5) und dem Flansch (3) mit dem Ansatz (4) besteht eine stoffschlüssige Verbindung aus einem Lötzinn (9) mit einem Silberanteil. Die Verbindung kann durch einen metallischen Überzug (12) abgedeckt sein.
摘要:
A color cathode ray tube is capable of reducing a rate of cracks in a furnace and improving the productivity of the CRT by improving a structure of a seal edge of a skirt of a panel. A color cathode ray tube according to the present invention includes a rectangular panel having a substantially vertically extending skirt on inner and outer surfaces of the panel and a funnel coupled to a seal edge of the skirt of the panel. The seal edge of the skirt of the panel has a corner having a specific curvature between a seal surface and a side of the skirt, and the following relationship is satisfied: 0.6 mm
摘要:
A vacuum vessel includes a first substrate, a second substrate facing the first substrate and spaced apart therefrom, and support frames mounted along the edges of the first and the second substrates. At least two support frames are separately formed on at least one side of the first and the second substrates. Adhesive layers are placed on a surface of the support frame facing the first substrate as well as on the opposite-surface of the support frame facing the second substrate to attach the two substrates and the support frames to each other. A filler is disposed between the neighboring support frames to prevent the vacuum leakage.

An image intensifier tube (10) having an evacuated tube envelope (12) and an output window (16) mounted in association with one end of the envelope (12) by a sealing arrangement (30, 36, 38, 40, 42) comprising ductile material (40) compressed between two opposing sealing surfaces (36, 42) one (42) forming a portion of the window (16) and the other (36) forming a portion of the envelope (12), the sealing arrangement effecting a substantially vacuum tight seal while permitting relaxation of stresses by allowing relative movement between the window (16) and envelope (12). The ductile material (40) is suitably indium although other ductile material such as gallium, lead, platinum, tin, gold and silver can be used as well. To form the seal the sealing surfaces (36, 42) are first metallized with a suitable wetting material, such as copper, a predetermined thickness of the ductile material (40) is then applied to a first one (36) of the metallized sealing surfaces (36, 42), the second metallized sealing surface (42) is then positioned in opposing coplanar relationship with the first (36) such that the second metallized surface (42) contacts the ductile material (40), the ductile material (40) is then compressed between the sealing surfaces (36, 42) thereby reducing the predetermined thickness of the ductile material (40), and finally the sealing surfaces (36, 42) along with the compressed ductile material (40) are heated to cause the ductile material (40) to wet the metallized sealing surfaces (36, 42).
