Abstract:
Beim Zusammenbau einer flachen Anzeigevorrichtung (1), die eine eine gerasterte Phosphorschicht (10) tragende Schirmplatte (4) und in Bezug dazu stehende Steuerplatten (2) aufweist, müssen diese Teile genau aufeinander aus gerichtet werden. Dazu weisen die Steuerplatten (2) Löcher zur Aufnahme von Justierstiften auf. Die Löcher sind zur genauen Ausrichtung mit einer Ringmetallisierung versehen.
Abstract:
A method for manufacturing an electron gun for a cathode ray tube. The method comprises a first step in which a number of securing means are made in a planar element (e.g. plate or strip), a second part in which the securing means are secured to an insulating support rod, a third part in which the insulating support rod-securing means assembly is detached from the planar element, whereafter connections are made to a stack of electrodes to form the electron gun.
Abstract:
The device comprises a base block (2) supporting four columns on which are mounted on one hand a system of translationally movable carriages (9, 10, 13, 14) supporting the intercalary blades (15, 16, 17, 18), and on the other hand a low portion (6) integral with a translationally movable slide-block (5), providing for the alignement of the different grids; a spring (4) or equivalent system provides for a bearing pressure; a high portion, called upper laying (8), locked with respect to the block (2) by a slide (11), acts as a positioning support for the cathode holders and the filament pins. The invention combined to a grid recentering device, is intended to the assembly of electron guns, and will be more particularly interesting in the case of an automated assembly.
Abstract:
Fabrication d'un assemblage d'électrodes consistant à former des fentes partielles (40) sur la surface inférieure d'une plaque de verre (10), à disposer des électrodes d'anodes (70) dans les fentes, à appliquer sur la surface supérieure de la plaque (10) des électrodes de cathodes (50) orientées transversalement par rapport aux anodes (70), à éliminer par gravage le reste du matériau de la plaque pour former des fentes traversantes (40) s'étendant entre la surface supérieure et la surface inférieure de la plaque (10), les anodes (70) et les cathodes (50) étant entre elles en relation de fonctionnement au travers des fentes.
Abstract:
An electron gun (10) comprises, as in prior guns, a plurality of cathode assemblies (16) and at least two spaced successive electrodes (18,20) having aligned apertures (60, 64) therethrough for passage of a plurality of electron beams. The cathode assemblies and the electrodes are individually held in position from a common ceramic member (50) The ceramic member has a first major surface (52) and an oppositely disposed second major surface (54), with a metallized pattern (56a, 56b; 56c) formed on at least a portion of each major surface. The electrodes are attached to the first major surface, and the cathode assemblies are attached to the second major surface. Unlike prior guns, a first transition member (74/78) is attached to the metallized pattern (65a, 56b) on the first major surface. At least one of the electrodes is attached to the first transition member. A second transition member (68, 94) may also be disposed on the second major surface for the attachment of the cathode assemblies.
Abstract:
Die Vorrichtung zum Zusammenbau von Elektronen strahler-zeugern für mehrstrahlige Kathodenstralröhren weist in einer grundplatte drei Dorne (2) auf. Die Dorne (2) tragen Abschnitte (4 bis 9) mit zentrierenden Umfangs flächen. Bei mindestens den beiden Abschnitten (4,5) mit den größten Durchmessern eines jeden dornes sind die Umfangsflächen in sich gegenüberliegende Teilflächen (13,14) aufgeteilt. Hierdurch wird ein einfaches Auffädeln der Gitterelektroden und seine leichte Entnahme des Elektronen strahlerzeugers von der Dornen (2) erreicht. Dies gilt insbe sodere, wenn das Elektronenstrahlerzeugersystem aus inte grierten Gitterelektroden besteht.
Abstract:
The invention discloses a method of making a mask structure Including two or more masks for a colour cathode ray tube, for example, a mask focusing colour cathode ray tube. A plurality of apertured flat masks, each mask having an effective portion having apertures and non-effective portion surrounding the effective portion, are aligned and stacked with a predetermined gap between them. The gap is then filled with filling material which solidifies, thereby fixing the flat masks together. The fixed masks are simultaneously pressed into a predetermined curved shape. The filling material is then removed from the curved masks.
Abstract:
The method of successively positioning and fixing n plates forming a stack (21-26) relative to a mounting face (20), includes the positioning and alignment, if necessary, of n plates (21-26), each plate (21-26) being retained, after it has been positioned relative to the mounting face (20) or relative to plates (21-25) which have already been positioned, by means of a vacuum in a vacuum pipe in the plates (21-25) already positioned. When all plates (21-26) are positioned and retained by a vacuum system connected to vacuum apertures (201-206) in the mounting face (20), successive plates (21-26) can be fixed relative to each other so as to form the stack of n plates (21-26). The vacuum pipes form ducts in the plates (21-25), at least one duct comprising i (i = 1, 2, 3, ..., n-1) corresponding apertures (215; 214, 224; 213, 223, 233; 212, 222, 232, 242; 211, 221, 231, 241, 251) in i plates (21-25) and being closed by a plate i+1 (21-26). Such stacks are used in thin-type display devices.
Abstract:
A flat panel display (11) of the field emission cathode type is described having polyimide spacers or pillars (39) separating the emitting surface (13) and display face (12) of the same. To provide spacers of constant height, a uniform polyamic ester coating is first applied by a spin coating process and photolithography techniques are used to form the spacer pattern prior to baking.
Abstract:
For a flat display device, a control subassembly is needed which consists of two control plates (1; 7) each formed by a layer of parallel conductors (2; 8) which are isolated from each other. During the manufacture of the control subassembly, the first control plate is provided with a glass frit in the form of continuous strips (10) perpendicular to the conductors. The glass frit is set, and the application of the strips is repeated. The second control plate is then put on the first control plate in such a way that their conductors are mutually perpendicular. After that, the glass frit is crystallized.
