Abstract: PROBLEM TO BE SOLVED: To provide a color picture tube with a shadow mask having sufficient strength. SOLUTION: The shadow mask 7 consists of a shadow mask body 14 having an effective portion ranging over a region corresponding to all display screen and a band auxiliary mask 20 fixed near a Y-axis of the shadow mask body. The outer periphery of the rectangular effective portion 13 of the shadow mask body contains a skirt portion 17. The auxiliary mask has an effective portion as a region having a number of opening holes corresponding to the holes on the shadow mask body, similarly to the shadow mask body, and non-effective portions located at both ends of a short axis (the Y-axis). With the auxiliary mask arranged and fixed near the Y-axis of the shadow mask body, the shadow mask 7 is formed in a partially doubled structure for improved strength.

Abstract: PURPOSE:To obtain color images, with large size, high luminance and high resolution, easy to see, by scanning multiple small regions divided from a screen part separately and discriminating the index signal from the central part of each small region and the index signal from the neighborhood of the periphery of said small region. CONSTITUTION:An index system color picture tube 1 equips a faceplate 3 with a screen part 2, nicks 5-1-5-12 connected with the faceplate 3 through it funnel 4, small electron gun parts 6-1-6-12 fitted within the necks 5 and deflecting yoked 7-14-7-12 and besides the funnel 4 equips a light receiving window 8 and a photoelectric converter 9. The screen part 2 equips phosphor 10 with phosphor stripes R, G, B as one group and index stripes 13, and the pitch Pp of the stripes 13 in the neighborhood of the separate scanning end part in each divided small region is formed to be one half of the pitch PA in other parts of the screen part. By doing so, it is possible to discriminate the index signal from the central part of each small region and the index signal from the neighborhood of its boundary between the neighboring small regions and scan the divided small region separately.

Abstract: PURPOSE:To make considerably large the electrode openig hole diameter of an electron gun and to make optionally small the space of an electron beam made incident on a deflection plane by performing small deflection in three steps before an electron beam is made incident on the center plane of deflection. CONSTITUTION:An electron beam 15 generated from a cathode 22 is controlled by the cathode 22 and the first and the second grids 23 and 24, and is accelerated and condensed by the third - the fifth grids 25-27, arriving at a screen plane, however, when it passes through the fourth grid 26, it receives an electrostatic deflection, the first small deflection, with a prescribed period at the fourth grid divided into two grids 26a and 26b. Therefore, three steps of deflection are applied and it means that three electron beams 15-17 are existed actually at the deflection plane of a main deflection. These actual three electron beams are deflected and scanned on the whole surface of the screen by a deflection yoke 7. At such a time, the space Sg between actual three electron beams at the center plane of deflection is decided according to the degree of the small deflection performed by the fourth grid 26, being made smaller optionally.

Abstract: PURPOSE:To produce an easily designed color picture tube device which can produce color images of high resolution, high convergence and high color purity over the entire surface of the screen by varying the degree of the first small deflection according to defletional scanning produced by the main deflecting part. CONSTITUTION:An electron beam 15 receives a first small deflection of two stages in the fourth grids 26a and 26b to produce electron beams 15-16 on the main deflection surface. The thus produced electron beams 15-17 are deflected and scanned over the entire surface of the screen by means of a deflection york 7. It is possible to produce a raster with good convergence quality by deflecting and scanning three electron beams 15-17 which are rightly converged and located at small distance. However, it is impossible to practically use the electron beams 15-17 because on the screen they are considerably apart from each other thereby resulting in a convergence shift. Therefore, convergence correction is performed by synchronizing the frequency of the first small deflection with the frequency of one horizontal deflection scanning line, making an image signal for each color to have a time difference and using a correcting coil 14 to produce a vertical second small deflection.

Abstract: PURPOSE:To prevent a drop of contrast in case of reverse display by applying low electron scattering-featured material on the surface except an image- displayed region on a fluorescent surface screen, out of metal packing layers in a monochrome cathode ray tube. CONSTITUTION:A neck part 1 including an electron gun 4, funnel part 2, front panel part 3, fluorescent screen 5, metal packing layer 6 formed by spattering aluminium on the inner side surface of the screen 5 and panel part 3 and on the inner surface of the funnel part 2, and aluminium film 6a are provided. On the surface of metal-film layers 6 and 6a, except an image-displayed region a, aqueous solution of graphite 8, in which amorphous silica of low electron scattering-featured material is added to form a monochrome cathode-ray tube. Hence, with the influence of scattering reflection electrons being lessened, an image with good contrast can be obtained even in case of a reverse display system.

Abstract: PURPOSE:To realize high accuracy of electrodes arrangement by assembling electrodes for an electron gun so that they have the same shape, before the said electrodes are positioned according to at least two concave parts of each electrode so as to assemble the electron gun. CONSTITUTION:Electrodes 51, 52...57 having the same shape are assembled by a combination of plate-like electrode elements 11a and cap-like electrode elements 11b. On the other hand, positioning blocks 41a and 41b, which correspond to concave parts 21 and 22 of the element 11a, are fixed to a reference block 46. At the same time, positioning blocks 42 and 43, which correspond to concave parts 23 and 24 of the element 11a, are fixed to the block 46, by using pins 44 and 45 that are buried in the block 46 as supports and guides, so that the blocks 42 and 43 are movable, thereby constituting an electron gun assembling tool. After that, the electrodes 51, 52...57 are stacked over the above assembling tool, and are positioned and fixed around an insulating supporting bar according to the concave parts 21, 22, 23 and 24. As a result, the accuracy of the assembly of an electron gun can be increased.
