    摘要: Deflection coils (32, 34) for deflecting an electron beam emitted from an electron gun (24) are provided outside a cathode-ray tube (12) in which the electron gun (24) is housed, and a phosphor screen (28) is formed. The cathode-ray tube (12) further includes a velocity modulation coil (18) for modulating a horizontal scanning velocity of an electron beam, a first magnetic substance (50) surrounding an outer circumference of the cathode-ray tube (12) from outside the velocity modulation coil (18), and a second magnetic substance (60) surrounding the outer circumference of the cathode-ray tube (12) between the deflection coil (32) and the first magnetic substance (50). Because of this, the sensitivity of velocity modulation can be enhanced effectively with a simple configuration while deflection distortion is prevented.

    摘要: A pair of velocity modulation coils (52 a, 52b) are placed with a horizontal plane including a tube axis interposed therebetween, and a pair of magnetic substances (54a, 54b) are placed with a vertical plane including a tube axis interposed therebetween. A straight line portion (53a) 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 (53a) 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 (54a, 54b) in the tube axis direction is present in a range of Z = 0.2 x L to 0.9 x 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 plurality of magnet rings (13A, 13B, 14, 15) for correcting a convergence are arranged in a tube axis direction with spacers (16, 17, 18) interposed therebetween, on an outer circumferential surface of a neck (3). A velocity modulation coil (19) for modulating a scanning velocity in a horizontal direction of an electron beam is placed so that a position of the velocity modulation coil (19) in the tube axis direction is overlapped with those of the magnet rings (13A, 13B, 14, 15). At least one of the spacers (16, 17, 18) is made of only a magnetic substance. Alternatively, at least one of the spacers (16, 17, 18) 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 (19) can be intensified without disturbing the magnetic field of the magnet rings (13A, 13B, 14, 15) of a CPU.

    摘要: On an outer circumferential surface of a neck portion (3 a) of a funnel (3), a CPU (9) having a pair of quadrupole magnets (93) and a pair of bar -shaped magnets (8) each having magnetic poles on both sides in a major axis direction are provided. The pair of bar-shaped magnets (8) sandwich the neck portion (3a) substantially in an in-line direction of an in-line type electron gun (4), and are provided so that identical poles are opposed to each other, between an end plate (63b) of an insulating frame (63) of a deflection yoke (6) and the CPU (9) at a distance from the end plate (63b). In the case where a rotational shift of electron beams is caused, electron beams (R) and (B) are corrected so as to move upward and downward (or downward and upward) respectively by a quadrupole magnetic field generated by the quadrupole magnets (93). Then, the electron beams (R) and (B) are corrected so as to move downward and upward (or upward and downward) respectively by the quadrupole magnetic field generated by the pair of bar-shaped magnets (8). Thus, a misconvergence due to the rotational shift of the electron beams can be corrected.
