Abstract:
A method for attaching a faceplate and a backplate of a field emission display device. Specifically, one embodiment of the present invention discloses a method for protecting a silicon nitride passivation layer from reacting with a glass frit sealing material that contains lead oxide during an oven sealing or laser sealing process. The passivation layer protects row and column electrodes in the display device. A barrier material fully encapsulates the silicon nitride passivation layer. In one embodiment, silicon dioxide is the barrier material. In another embodiment, spin-on-glass is the barrier material. In still another embodiment, cermet is the barrier material.
Abstract:
In a novel method in the field of the production of discharge vessels, in particular for silent flat radiators, an exhaust tube 3 for evacuating and filling is inserted into an opening 2 in the discharge vessel, it being possible in a simple way by means of an adapter 4 to achieve optimum fitting and sealing between a square inner cross section of the opening 2 and a round outer cross section of the exhaust tube 3.
Abstract:
An x-ray tube is provisionally assembled by interposing an upright part (12A) projecting from a first brazing agent (A) between a stem (3) and a bulb (2), and by interposing a second brazing agent (B) between the bulb (2) and an output window (4). This temporary assembly is conveyed into a vacuum brazing oven (P). Since a gap (K) is provided between the stem (3) and the bulb (2) by the upright part (12A), gas inside the bulb (2) can be discharged through the gap (K). Then, the vacuum brazing oven (P) is heated to a predetermined temperature to melt the first and second brazing agents (A, B), to thus fuse-bondingly fix the stem (3) and the output window (4) to the bulb (2). Brazing connection is completed in the vacuum brazing oven (P) while maintaining the sealed vessel (7) in a high vacuum condition without provision of a discharge pipe in the stem (3).
Abstract:
The present invention provides an AC memory type plasma display panel comprising a pair of substrates and stacked together via a sealing member so as to have a discharge space therebetween, and discharge electrodes and a dielectric layer covering the discharge space therebetween, and discharge electrodes and a dielectric layer covering the discharge electrodes formed on at least one of the substrates. The dielectric layer is formed on the surface of the substrate including a display region and a portion outside the display region in which the sealing member is located. The thickness of the portion for bonding of the sealing member outside the display region is smaller than the thickness of the portion corresponding to the display region.
Abstract:
A high-pressure discharge lamp includes a glass housing made of a high-melting vitreous material, a pair of sealing components made of the same high-melting vitreous material and extended from the glass housing. A rare gas and a material that is solid or liquid at room temperature is sealed inside the glass housing. Electrically conductive bars are embedded in the sealing components. The air-tight seals around the electrically conductive bars are formed such that at least one metal material selected from metals and oxides of said metals is provided near the regions lying between the high-melting vitreous material and the electrically conductive bar.
Abstract:
Disclosed is a method for producing an electrochromic device in which to provide an opening in the surface of each of the two electrically conductive substrates of the cell, not in the end surface of the opposed substrates, to insert into one of the openings an elastically deformable sealing member; to fill the inside of the cell by vacuum-injecting an electrolyte or the precursor thereof through the other opening which remains open; to push the sealing member up to the opening for injecting the electrolyte or the precursor so as to dose this opening as well; and to bond the sealing member extending through the two openings to each of the substrates with an adhesive.
Abstract:
The present invention relates to a method of packaging a field emission display. The method of packaging a field emission display, comprising the steps of: forming an opening on a selected area of a lower substrate on which field emission elements are formed and forming a silicon layer on a lower surface of said lower substrate; combining a upper substrate, on which a transparent electrode and luminescent material are formed, and said lower substrate by a lateral wall; placing a cap on said opening after performing a vacuum process through said opening; performing a thermal treatment process so that said cap is combined with said silicon layer by silicide created by the reaction of said cap and said silicon layer, thereby sealing said opening; and completely sealing said opening by adhesives.

A method of manufacturing an image display apparatus in which a first substrate on which fluorescent body exciting means is arranged and a second substrate on which a fluorescent body that emits light by the fluorescent body exciting means is arranged are arranged so as to face each other and are adhered through joining members at their peripheries, wherein a seal bonding step of adhering the first and second substrates through a joining members and a step of performing a position matching of the first and second substrates are executed in a vacuum.
Abstract:
This invention secures the breakdown voltage between stem pins or the like for high voltage service in a cathode ray tube. This insulator formed is of a clay-like silicone compound having a tip-throughhole and pin-throughholes or a stem base with the electric insulator mounted to the stem base: A inter-stem electric insulation device is structured by mounting either one of the electric insulator or the stem base with the electric insulator to the stem of a cathode ray tube and by pressing to fix together. This structure does not occur bubble generation caused by the electric insulator, and makes the handling easy, and furthermore, accomplish an automatic mounting of the electric insulator to a stem.
