摘要： PURPOSE:To enhance vibration-proofness as well as to make a device small in size and light in weight by applying load to a space between long side sections with the deformation of frame short side sections restrained, stretching color selection electrodes so as to be welded with each support piece compressed, and thereby imparting required tension to the electrodes with load and restraint removed. CONSTITUTION:The lateral and vertical movement of a frame body is restrained with frame short side sections 16a and 16b fixed by restraining jigs 21 and 22. Next, load (f) is applied to a space between frame long side sections 13a and 13b, so that each support side 12a and 12b made of spring material and each long side section 13a and 13b are deformed by a specified amount. Color selection electrodes composed of a great number of fine string elements 14 are stretched so as to be mounted across the space between the long side sections 13a and 13b, so that they are welded so as to be fixed. And when the load (f) is then removed, required tension is imparted to the color section electrodes by means of the restoring force of both the long side sections and support pieces. By this constitution, tension is prevented from being lowered due to the deformation of the frame body, so that required tension can easily be provided, and resonance due to external vibration is concurrently restrained, so that a device can also be made small in size and light in weight.

摘要： PURPOSE:To improve reproducibility of a relative position between a color selection electrode and a fluorescent screen inside a phase plate by holding the color selection electrode near to the corner parts inside the panel glass. CONSTITUTION:A color selection electrode device 7 is held, inside the panel glass, with 4-point support in corner parts by fitting support pins into through holes 27 of support members 24a-24d. Unnecessary torsion which may occur in manufacturing the electrode device 7 is then corrected, and a selection electrode 12 and a fluorescent section can easily be set in a specific relative position. With this constitution, in a process forming a fluorescent screen inside a phase plate, reproducibility of a relative position between the selection electrode 12 and the fluorescent screen all partly formed on the inner surface of the phase plate is improved, and precise picture quality is obtained.

摘要： PURPOSE:To provide a color screening electrode device capable of uniformly stretching color screening electrodes. CONSTITUTION:When the distance between opposite long sides of a frame 25 is pinched and compressed, short sides of the frame 25 are bent with an electrode suspension opening face 27 faced inwardly, the bent short sides of the frame 25 are deployed at the time of a release, and deploying spring pieces 2-5 stretching color screening electrodes 26 are provided. When the distance between the long sides of the frame 25 are pinched and compressed by the deploying spring pieces 2-5, the short sides of the frame 25 are invariably bent in the fixed direction, thus the frame 25 can be deformed in the stable state. The relative position between both frame bodies 21, 22 is stabilized when the color screening electrodes 26 are suspended, and the color screening electrodes 26 can be uniformly stretched at the time of release.

摘要： PURPOSE:To provide a color select electrode with a uniform tension using a simple and lightweight structure without sacrificing the frame rigidity by installing the electrode as set over between frames, and giving a tension to this electrode with the restoring force of support pieces consisting of a spring material. CONSTITUTION:A load is applied between frames 21a, 21b facing each other, and support pieces 22 consisting of a spring material are deflected a certain amount within the electric range, and the span between the frames 21a, 21b is compressed, where a number of thin element wires 11 are set over and welded fast. If the load is removed, the restoring force of the support pieces 22 gives required unifor tension to the element wires 11, and even though a thermal expansion is generated in the element wires 11 by irradiating with electron beam, the resultant elongation of the wires is set off with the displacement of the support pieces 22, and the element wires 11 will have approx. the same tension as the initial value. Thus a tension distribution having required uniform tention can be obtained using a simple constitution.

摘要： PURPOSE:To eliminate the blackning heat treatment, to suppress the lowering of the tension on electrodes, and to improve the vibration resistance so as to obtain precise pictures, by using hardly stainable materials such as stainless materials for color selecting electrodes, frames and supporting pieces. CONSTITUTION:A load is applied between frames 10a, 10b made of corrosion resistance materials bending supporting pieces 10c, 10d consisting of corrosion resistance spring materials by a specified amount in the elastic region, and color selecting electrodes 11 made of the above materials are strung between the frames, and the load is removed after welding and fixing the electrodes 11 to the frames respectively. The compression of the frames is removed and tensions of specified distribution are applied to the electrodes 11 respectively by the restoring force of the spring members. By using hardly stainable materials such as stainless materials foe a color selecting electrode assembly 7 the generation of stains can be prevented to eliminate the blackning heat treatment, a stain preventing process, and the manufacture can be simplified, and the lowering of the tension can be suppressed to obtain sharp pictures of high precision in color cathode-ray tube operations.

摘要： PURPOSE:To obtain uniform tension and reduce a damping time constant by stretching a color selection electrode between frameworks in such a way that load distribution of a load applied to each central portion of the frameworks is larger at both ends of the frameworks. CONSTITUTION:Filament elements 11 are tensely stretched by utilizing restoring force of support pieces 22, and at the time of stretching, a distributed load is applied to frameworks from the outside so that distance of the central portion between the frameworks 21a, 21b becomes shorter than that between both end portions of the frameworks. Consequently, the frameworks 21a, 21b can gain uniform tension both at their central portions and end portions, and since resonance of the filament elements 11 which may be caused by vibration from the outside is prevented, stretching a damper wire can be eliminated. Further, by making each section of the frameworks 21a, 21b a U-shape, the filament elements 11 as a color selection electrode can be made small sized and lightweight.
