Abstract: This invention relates to a reusable factory fixture frame (82) and process for using same in the manufacture of a color cathode ray tube (20) having a flat faceplate (24) and a tensed foil shadow mask (50). The frame provides for mounting an in-process shadow mask during photoexposure of an in-process faceplate in a lighthouse (122). The frame (82) comprises generally rectangular frame means and quick-release mechanical mask-retaining means (88) for temporarily and removably supporting an in-process shadow mask in tension. The frame (82) includes a generally rectangular frame structure having grooves (24) thereabout for receiving an edge (26) of the shadow mask. The mask retaining means (88) may comprise spring-loaded mechanical mask-retaining devices (18) which are secured to the side of the factory fixture frame or quick-release mechanical spring clips (34) for temporarily and removably supporting the in-process shadow mask in tension in the grooves. Alternatively at least one elongate rod-like (28) member extending lengthwise of and complementarily mating with the grooves in the frame structure may be employed for temporarily and removably supporting an in-process shadow mask in tension. The shadow mask is heated and allowed to expand prior to being temporarily and removably supported on the frame, and the shadow mask is allowed to cool and shrink in tension while so being supported to effect tensing of the shadow mask in clamped condition on the frame. Preferably, the frame has at least first six-point indexing means (132) on a first side (84) for registration with complementary registration-affording means (134) on an exposure lighthouse (122), and second six-point indexing means (136) on a second, opposed side (118) for registration with complementary registration-affording means (138) on an in-process faceplate (120). As a result, the in-process shadow mask can be precisely registered and re-registered with the lighthouse (122) and the in-process faceplate (120) for the photoexposure of the in-process faceplate while retaining the in-process shadow mask in tension.

Abstract: An improved front assembly for a color cathode ray tube having a tension foil shadow mask. The faceplate of the tube has on its inner surface a centrally disposed phosphor screen surrounded by a peripheral sealing area adapted to mate with a funnel. A shadow mask support structure (34) is provided for supporting a shadow mask in tension on the structure and spacing the shadow mask from the screen. The support structure includes an undulated member (60) surrounding the phosphor screen which member can take a number of forms including a strip defining a bottom sinuous edge (64) for securing the support structure to the faceplate and a top sinuous edge (62) for securing the shadow mask to the support structure. A cap (68) may be provided for securement to the top sinuous edge of the undulated strip to provide a land for securing the shadow mask to the support structure. Alternatively, the undulated member can be formed with peaks (66a) and valleys (66b) which are flattened in a common plane and provide means for securing the support structure to the faceplate. The peaks are flattened in a common plane and provide means for securing the shadow mask to the support structure. In a further modification, the support member includes an upper, flattened ridge for securing the shadow mask to the support structure. A plurality of legs depend from the ridge and at least a series of the legs is flared outwardly from one side of the ridge to facilitate securing the support structure to the faceplate and to stabilize the support structure under the tension of the shadow mask. Preferably, the mask support structure physically penetrates the faceplate for permanent, cementless anchoring of the structure to the faceplate. The embedment of the mask support structure is of such depth as to cause the structure to resist tensile forces created by the mask. Also disclosed is a process for securing a support structure for a tensed foil shadow mask to a glass faceplate.

Abstract: Process and apparatus are disclosed for use in the manufacture of a color cathode ray tube having a shadow mask with a central pattern of apertures mounted in tension on a transparent flat front panel. The mask aperture pattern is registered with a cathodoluminescent screen pattern of corresponding geometry and position on an inner surface of the panel. The shadow masks and front panels are respectively interchangeable. Signals are developed which are indicative of the positions of a mechanically stretched mask aperture pattern and an associated front panel screen pattern relative to a reference or to each other. Responsive to such signals, there is effected a relative positioning of the mask and screen until registration between the patterns is achieved.

Abstract: Procédé et appareil à utiliser lors de la fabrication de tubes à rayons cathodiques de couleur, comportant un masque perforé doté d'un motif central d'orifices monté de manière tendue sur un panneau antérieur plat et transparent. On fait concorder le motif des orifices du masque avec un motif d'écran cathodoluminescent à géométrie et position correspondantes, agencé sur une surface intérieure dudit panneau. Les masques perforés et les panneaux antérieurs peuvent être changés. Des signaux sont générés, qui indiquent les positions d'un motif d'orifices de masque mécaniquement étiré et d'un motif correspondant d'écran de panneau antérieur, par rapport à un élément de référence ou l'un par rapport à l'autre. Le masque et l'écran sont ensuite positionnés l'un par rapport à l'autre en fonction desdits signaux jusqu'à ce que les motifs concordent.

Abstract: Cadre de support (82) réutilisable et procédé d'utilisation de ce cadre dans la production d'un tube cathodique couleur (20) possédant un écran plat (24) et un masque d'ombre à feuille tendue (50). Ce cadre permet le montage d'un masque d'ombre de traitement pendant la photoexposition d'un écran dans une installation d'exposition (122). Le cadre (82) est généralement rectangulaire et comprend un organe mécanique de retenue du masque à libération rapide (88) supportant temporairement et de manière amovible un masque d'ombre de traitement tendu. Le cadre (82) comprend une structure généralement rectangulaire possédant sur son pourtour des rainures (24) qui reçoivent un bord (26) du masque d'ombre. L'organe de retenue du masque (88) peut comprendre des dispositifs mécaniques (18) de retenue du masque à ressort, fixés sur le côté du cadre de support, ou des agrafes mécaniques à ressort à libération rapide (34) qui supportent temporairement et de manière amovible le masque d'ombre de traitement tendu dans les rainures. Dans une variante, au moins un organe allongé en forme de tige (28) s'étendant dans le sens de la longueur des rainures dans la structure du cadre peut être utilisé pour supporter temporairement et de manière amovible un masque d'ombre de traitement tendu. Ledit masque d'ombre est chauffé et se dilate avant d'être supporté temporairement et de manière amovible par le cadre; on le laisse ensuite refroidir et se rétracter sous tension, en le supportant de manière à obtenir la mise sous tension du masque alors qu'il est accroché au cadre. De préférence, le cadre possède au moins un premier organe de repérage à six points (132) sur un premier côté (84) pour l'alignement avec un organe d'alignement complémentaire (134) sur une installation d'exposition (122), et un deuxième organe d'alignement à six points (136) sur un deuxième côté opposé (118) pour l'alignement avec un organe d'alignement complémentaire (138) sur un écran (120). Cet agencement permet l'alignement et le réalignement précis du masque
