摘要： A bar-shaped element includes magnets at both ends and a magnetic material connecting the magnets to each other. One end in a major axis direction of the bar-shaped element is an N-pole, and the other end is an S-pole. A pair of bar-shaped elements sandwich a deflection yoke in a horizontal direction, with the major axis direction thereof being parallel to a vertical direction, and each of the bar-shaped elements is placed at a position between the end of a horizontal deflection coil on a phosphor screen side and a central position of a core in a tube axis direction, in such a manner that the magnetic poles at both ends are opposite to each other between the pair of bar-shaped elements. Because of this, PQH misconvergence is corrected without influencing power consumption at low cost by a simple method without using an auxiliary coil and a correction circuit, whereby satisfactory convergence can be realized.

摘要： A pair of coma aberration correction coils and a pair of YH correction coils are placed in upper and lower portions on an electron gun side from a ferrite core, and a pair of vertical auxiliary coils generating a magnetic field in the same direction as that of a vertical deflection magnetic field are placed in right and left portions on the electron gun side from the ferrite core. A horizontal deflection coil has a first coil and a second coil on an inner circumferential side of the first coil. A useful portion of the second coil is placed in a range of ±45° from a vertical axis with respect to a tube axis, and a bend portion of the second coil is placed on the electron gun side from a position that is away from the end on a screen side of the ferrite core to the screen side by 10 mm. Because of this, the misconvergence of PQH can be suppressed without increasing cost and power consumption with a simple configuration.

摘要： In a color CRT apparatus in which three electron beams are not superimposed on one point on the screen at a time, a time difference is applied to modulating signals corresponding to the respective electron beams to adjust phase, thus achieving convergence of images, the screen is flat, both a horizontal magnetic deflection field and a vertical magnetic deflection field have uniform magnetic field distribution, paths of both side electron beams and a path of the center electron beam of the three electron beams emitted from electron sources are approximately parallel, and the time difference applied to the modulating signals is set to be approximately constant throughout the screen. Thus, images formed of imaging spots of the three electron beams can be superimposed on the screen with high precision to be matched without causing increased cost.

摘要： A color picture tube device that can adjust convergence without causing increases in cost and in power consumption is provided. One pair of magnetic flux generation means for generating a static quadrupole magnetic field are positioned above and below an area where a plurality of electron beams pass through. The static quadrupole magnetic field has an effect of adjusting convergence in a horizontal direction. In this construction, a magnetic flux generated by one of the two magnetic flux generation means that is closer to the plurality of electron beams is reduced, in sync with deflection of the plurality of electron beams in a vertical direction.

摘要： A color picture tube device that can suppress the deformation of the electron beam spot shape and improve the horizontal resolution using a simple construction is provided. A horizontal deflection coil generates a horizontal deflection magnetic field that is substantially uniform. A plurality of electron beams are substantially parallel with the tube axis when passing one end of a core of a deflection yoke facing an electron gun. A lens forming unit forms a lens through which the plurality of electron beams pass, between the electron gun end of the core and a phosphor screen. The lens has an effect of causing the plurality of electron beams to approach each other in a horizontal direction, irrespective of which part of the phosphor screen the plurality of electron beams reach.

摘要： A ferrite core constituting a deflection yoke has a plurality of ridge-shaped convex portions on an inner circumferential surface. In a cross-section orthogonal to a center axis, the cross-sectional shape of an outer circumferential surface of the ferrite core is substantially circular, and the cross-sectional shape of an inner circumferential surface of the ferrite core excluding the convex portions is substantially circular in the vicinity of an end on a large diameter side of the ferrite core and is substantially rectangular in a portion between the vicinity of an end on a small diameter side and the vicinity of the end on the large diameter side. This can provide a low-cost color picture tube apparatus with a reduced deflection power and satisfactory productivity.

The deflection yoke has at least one cross section orthogonal to a tube axis that satisfies the following A to C. A: A plurality of magnetic substance convex portions projecting toward the tube axis are provided in the vicinity of a position of an inner surface of the ferrite core where a vertical axis crosses. B: Assuming that a minimum value among distances between the respective magnetic substance convex portions and a funnel is D1, the distance between the ferrite core excluding the plurality of magnetic substance convex portions and the funnel is larger than the distance D1 at any point of the ferrite core. C: Apart of the vertical deflection coil is wound in a groove between the plurality of magnetic substance convex portions. Because of this, a satisfactory convergence and raster can be realized while a power-saving effect is exhibited sufficiently.
