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.

A vacuum vessel includes first and second substrates facing each other, and a sealing member arranged at peripheries of the first and the second substrates to define a vacuum-tightly sealed inner space together with the two substrates. The sealing member has a support frame of a predetermined width and a predetermined height, and an adhesive portion arranged external to the support frame to attach the first and the second substrates together. The support frame is wider than the adhesive portion, and the difference between the width and height of the support frame is within a range of ±10% of the width or the height.

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

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

A funnel-shaped chip tube and a tubular-shaped press frit are prepared. After the chip tube is disposed on a major surface of a substrate so that the center axis of an exhaust hole provided in the substrate of a sealed container body and the center axis of the chip tube may substantially coincide with each other, the press frit is so disposed as to be located on a surface of an opening portion. After that, by heating the whole device, the press frit is heated and melted, to provide a sealing member contiguously from an outer-rim outside portion of the flare-shaped opening portion of the chip tube to a portion of a tubular portion beyond a boundary.

In an electronic tube, a metal cylindrical member having, at the end, a cylindrical joint portion is bonded by brazing to the end of ceramic cylindrical member to form a hermetic seal structure. The metal cylindrical member is made of iron and dimensions thereof are specified such that the cylindrical joint portion has a wall thickness of 0.5 mm or less and a height of 1 mm or more.

An image display device includes two substrates disposed in opposite to each other with a gap, and a vacuum sealing portion which seals predetermined positions of the substrates and defines a sealed space between the two substrates. The vacuum sealing portion has a sealing material 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.

The present invention relates to a discharge vessel (1) with at least one end part (2) and a discharge cavity (3), whereby the discharge vessel (1) is at least partly coated with a coating layer (4), and whereby the gas-tight bonding of the coating layer to the discharge vessel (1), to a sealant (5) and/or to an end closure member (9) is stronger compared to the direct gas-tight bonding of said sealant (5) to said end closure member (9) and/or discharge vessel (1).
