摘要： PURPOSE:To obtain a good raster by providing a permanent magnet on a vertical axis of a deflecting yoke so as to form a magnetic field by which an electron beam is deflected vertically, and by providing a piece of a magnetic substance with which a magnetic pole of the permanent magnet is magnetically linked. CONSTITUTION:A pair of permanent magnets 23 are formed on a vertical axis Y of a deflecting yoke 19 in symmetry upward and downward to a horizontal axis X, so as to form a magnetic field by which an electron beam is deflected vertically. This is horizontally extended so that a magnetic pole of the permanent magnet 23 and one end are linked together magnetically, and the other end is receded from the vertical axis Y, while a piece of magnetic substance 24 is provided so that the other end is situated closer to the horizontal axis X than the magnetic pole of the permanent magnet 23. Pin cushion type distortion of the upper and lower parts of the display can be adjusted by a pin cushion type magnetic field that is generated by the magnetic pole of the permanent magnet 23, as well as the drop of the end of the distortion of high degree can be adjusted by the magnetic field generated by the end of the piece of the magnetic substance 24. A good raster can thus be obtained.

摘要： PURPOSE:To make an unbalanced hysteresis curve different for every one cycle and to eliminate a residual magnetism by passing the alternating transient attenuating current having a relation in which the ratio of a demagnetizing frequency and a vertical deflecting frequency is not an integer to a demagnetizing coil to demagnetize. CONSTITUTION:The demagnetizing coil 14 is disposed at the prescribed position of a cone part 11 side correspondingly to a shadow mask 5 incorporated in a color image receiving tube or a magnetic member such as an internal magnetic shield body 13, an electron beam discharge from an electron gun is deflected by the horizontal and the vertical deflecting magnetic fields of a deflecting yoke 12 to scan a screen and the alternating transient attenuating current is passed to the demagnetizing coil disposed externally of the cone part to demagnetize. I this case, the hysteresis curve 32 generates the unbalance in respective cycles, the unbalanced pattern is changed for every cycle, consequently, the hysteresis curve 32 of the respective demagnetizing cycles is averaged to demagnetize with no generation of the residual magnetism as shown by a point (r).

摘要： PURPOSE:To effectively restrain the thermal deformation of a shadow mask by allowing the difference between panel wall thickness on the major axis (X-axis) and panel wall thickness in proximity to the both ends in the minor axis (Y-axis) direction to be maximum at the midsection in the X axial direction of the effective curved surface of a panel. CONSTITUTION:Out of cross sections in parallel with the Y-axis and the Z-aixs in a panel effective arear 33, the difference between wall thickness h1 on the X-axis of a cross section 52 passing through the center O of a panel and wall thickness H1 at the end section in the Y-axis direction, is smaller than the difference between wall thickness h2 on the X-axis of a section 53 in parallel with the Y-axis and the Z-axis at the midsection M in the X-axis direction and wall thickness H2 at the end section in the Y-axis direction. In addition, the difference between wall thickness h3 on the X-axis of a cross section 54 in parallel with the Y-axis and the Z-axis at the end section P of an effective diameter in the X-axis direction and wall thickness H3 at the end section in the Y-axis direction is similarly smaller than the difference between wall thickness h2 on the X-axis of the cross section 53 at the midsection and wall thickness H2 at the end section in the Y-axis direction. Namely, the difference in thickness is maximum at the midsection M. This constitution thereby can prevent effectively purity in color from being deteriorated caused by partial thermal deformation of a shadow mask 36 only by partially changing the form of a curved surface.

摘要： PURPOSE:To check any thermal deformation in a shadow mask by making the major axial radius of curvature on an effective curved surface smaller in a side in and around a minor axis effective diameter end than the central part and making the diagonal axial end vicinity larger than the major axis effective diameter end vicinity. CONSTITUTION:A shadow mask 36 tructure 32 consists of a rectangular mask frame 34 and a curved shadow mask provided with a lot of through holes, and these through holes are formed in a rectangular area 33 with a slit along a Y-axis direction in response to stripes of a fluorescent screen 30, and this area 33 serves as an effective area for image projection. With the center O of an effective curved surface as a reference point, a major axis is set to an X-axis, a minor axis to a Y-axis and the center axis to a Z-axis, respectively. An X-axial radius of curvature in the minor axis effective diameter end vicinity is made smaller than an X-axial radius of curvature in and around the central part of the effective surved surface, and an X-axial radius of curvature in and around the diagonal effective diameter end is made larger than the X-axial radius of curvature in and around the major axis effective diameter end. Thus, thermal deformation in the shadow mask is checkable.

摘要： PURPOSE:To keep the correction for purity drift well enough for a long time by making the angle between the tube axis and a movable piece apart smaller than the angle between the tube axis and the straight line connecting the end part of the movable piece at the frame side to a stud-pin in the cross section of a spring component in the diagonal axis direction. CONSTITUTION:A shadow-mask 12 is fixed by welding to a frame 13. A spring component 24 is made of three components welded each other: the one is a fixed part 21 fixed by welding to the frame 13, and the other: are a connecting part 23 which a stud-pin 14 is fitted in the hole of and a movable piece part 22 connecting the fixed part 21 to the connecting part 23. The angle a between the tube axis and the straight line 35 connecting the end part 34 of the movable piece part 22 at the frame side to the center of the top of the stud-pin 14 is made larger than the angle beta between the tube axis and the movable piece part 22. Thereby purity drift is able to be efficiently improved for a long time without making a great change in the conventional spring component.

摘要： PURPOSE:To form a required phosphor screen without lowering tube characteristics and easily by irradiating light from a long light source on a panel, moving the panel in the longitudinal direction of the long light source. CONSTITUTION:A panel 1 is light-exposed, being moved in the direction of throughhole array of a shadow-mask 2 arranged through a bridge i.e. in the longitudinal direction of a long light source. This can sufficiently correct the constriction of stripes generated by the influence of the bridge of the shadow- mask 2. Besides, the allowable ranges of the moving distance and moving speed of the panel 1 is wide. Therefore, the adjustment for correcting the constriction becomes easy, resulting that the stripes almost without constriction can easily be formed. And since this method is that of concurrently light-exposing the whole face of the panel 1, the exposure time can be shortened. The variation of the positional relationship between the panel and a landing correcting lens is small and also the tube characteristics do not happen to be lowered.

摘要： PURPOSE:To correct a meandering and a constriction of stripes formed over the inner surface of a panel, by specifying the form of a negative meniscus lens. CONSTITUTION:A negative meniscus lens 22, where the axis passing through the center of the lens 22 is made Z axis, the longitudinal direction of the long light source 3 is made Y axis, and the axis perpendicular to the Y and Z axes is made X axis, the curvature of the crossing line between the inner face of the lens 22 and the YZ plane is larger at the center and smaller at the periphery. And the curvature of the crossing line between the YZ parallel plane parallel to the YZ plane and the lens 22 is also smaller at the periphery than at the top of the crossing line. This is same as the case to make the form of the crossing line between the YZ plane and the YZ parallel plane, and the negative meniscus lens 22 into a parabola, for example. By using such a negative meniscus lens 22 to radiate the light to the inside of the panel through a slot- form permeable hole, stripes with no meandering and constriction can be formed.

摘要： PURPOSE: To inhibit the deterioration of color purity resulting from local thermal expansion of the shadow mask caused by the impact of electron beams by specifying the shape of the shadow mask.
CONSTITUTION: A color picture tube is assembled by installing a shadow mask 36 having many holes near a fluorescent screen 30 formed on the inner surface of a rectangular panel 24. When the longer axis, the shorter axis and the central axis of the shadow mask 30 are supposed to be X axis, Y axis and Z axis respectively, the curvature radius of line (YF) formed by the (X-Y) plane and the effective curved surface exhibits the minimum level between the center (O) of the mask 36 and the end (P) of the line (XO) formed by the (Y-Z) plane and the effective curved surface. Accordingly, it is possible to prevent any mislanding occurring in a relatively short time, thereby inhibiting the deterioration of color purity.

摘要： PROBLEM TO BE SOLVED: To provide a deflecting yoke, and cathode-ray tube equipment equipped with this, which can aim at reduction of deflecting electric power, manufacturing cost, and reduction of heat value. SOLUTION: A vacuum envelope has an almost truncated polygonal pyramid-shaped yoke mounting part, and the deflecting yoke, which is equipped to the yoke mounting part, is equipped symmetrically to its center axis. Moreover, it has a pair of saddle type level deflecting coils 30a and 30b, which are made to have the shape of the mostly truncated-pyramid. A separator 33 is formed in the perimeter side of the horizontal deflecting soils, and a magnetic body core 34 of a mostly truncated-cone shape is formed in the outside of the separator, in the same axis with the main axis. A pair of vertical deflecting coils is wound in a troidal manner to the magnetic body core. In a direction of a horizontal axis, which intersects perpendicularly with the center axis of the horizontal deflecting coils, it has the minimum interval part, where the interval between the magnetic body core and the horizontal deflecting coil becomes the minimum, at near the end part of the side of the small diameter side of the magnetic body core. And the interval of the magnetic body core and the horizontal deflecting coil is increasing from this minimum interval part toward the large diameter side end of the magnetic body core.

摘要： PROBLEM TO BE SOLVED: To provide a color cathode-ray tube equipped with a shadow mask having sufficient strength, and a method for manufacturing it. SOLUTION: A shadow mask 7 is structured by superimposing an auxiliary mask 20 on a mask body 14. The mask body faces the almost whole face of a phosphor screen and has a mask 40 having an almost rectangular effective area where many electron beam passing holes are formed, and a skirt part 17 extending from the peripheral rim of the main face of the mask. The auxiliary mask is fixed by superimposing it on the vicinity area of the short axis Y of the effective area of the mask body, and is formed in a band shape formed with this short axis as a longitudinal direction. It also has many electron beam passing holes corresponding to the many electron beam passing holes of the mask body. The auxiliary mask has a grip part exposed without being superimposed on the mask body and graspable from the outside.
