    摘要: 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.

    摘要: 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.

    摘要: 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.
