摘要： A plurality of magnet rings for correcting a convergence are arranged in a tube axis direction with spacers interposed therebetween, on an outer circumferential surface of a neck. A velocity modulation coil for modulating a scanning velocity in a horizontal direction of an electron beam is placed so that a position of the velocity modulation coil in the tube axis direction is overlapped with those of the magnet rings. At least one of the spacers is made of only a magnetic substance. Alternatively, at least one of the spacers is made of a magnetic substance, and the outermost surface in a radius direction of the spacer made of a magnetic substance is covered with a non-metallic material. Because of this, the magnetic field formed by the velocity modulation coil can be intensified without disturbing the magnetic field of the magnet rings of a CPU.

摘要： A pair of velocity modulation coils are placed with a horizontal plane including a tube axis interposed therebetween, and a pair of magnetic substances are placed with a vertical plane including a tube axis interposed therebetween. A straight line portion of the velocity modulation coil extending substantially in parallel to the tube axis is placed between the magnetic substance and the tube axis. An interval D between the magnetic substance and the straight line portion is 1 to 3 mm. Assuming that the tube axis is a Z-axis, a size of the velocity modulation coil in a tube axis direction is L, and a position of an end of the velocity modulation coil on a side opposite to a phosphor screen in the tube axis direction is Z=0, a center point of the pair of magnetic substances in the tube axis direction is present in a range of Z=0.2×L to 0.9×L. Consequently, the sensitivity of velocity modulation can be enhanced while suppressing an increase in a driving power with a simple configuration.

摘要： A deflection yoke device includes a deflection yoke for deflecting electron beams in horizontal and vertical directions, the electron beams being emitted from an electron gun of a color cathode ray tube; coma correcting coils positioned on an electron gun side of the deflection yoke so as to be opposed to each other in such a manner that the electron beams pass therebetween; and a pair of cores around which the coma correcting coils are wound, wherein a sliding mechanism is further provided for allowing each of the coma correcting coils to be slidable with respect to the corresponding core. Therefore, a misconvergence can be corrected by a simplified configuration without reducing a sensitivity of the coma correcting coils.

摘要： A CRT apparatus is composed of a CRT, a deflection yoke, a velocity modulation coil, and a magnetic member. The CRT includes a glass bulb made up of a panel and a funnel connected together and an electron gun housed within the glass bulb, and emits an electron beam from the electron gun toward a phosphor screen formed on an inner surface of the panel. The deflection yoke includes a horizontal deflection coil and a vertical deflection coil, and scans the electron beam over the phosphor screen. The velocity modulation coil is arranged outside the CRT, and modulates a velocity at which the electron beam is scanned horizontally. The magnetic member is arranged to surround an outer circumference of the CRT with the velocity modulation coil positioned therebetween, so as to cover a position corresponding to a space between axially aligned electrodes of the electron gun.

摘要： A pair of coma coils for correcting a VCR that is a positional displacement in a vertical axis direction of a center electron beam with respect to the center of a pair of side electron beams on a vertical axis in upper and lower portions on a screen are provided at a position in the vicinity of an end of a deflection yoke on an electron gun side. Assuming that a maximum value of the intensity of a vertical deflection magnetic field on a tube axis is HMAX, and the intensity of a vertical deflection magnetic field on the tube axis at the position where the pair of coma coils are arranged in the tube axis direction is HC, HC/HMAX≧0.8 is satisfied. Owing to this, high-order distortion of horizontal lines on a screen can be corrected.
