摘要： A color cathode ray tube apparatus includes: a valve; a phosphor screen; an electron gun including an electron beam generating portion (17) for generating three electron beams, a focusing electrode (13), an anode electrode (12), a first field correction electrode (15) and a second field correction electrode (16); and a deflector for deflecting the electron beams emitted from the electron gun, wherein the focusing electrode (13), the first field correction electrode (15), the anode electrode (14) and the second field correction electrode (16) form an electron lens having a focusing force in a vertical direction, which is perpendicular to the horizontal direction, stronger than its focusing force in the horizontal direction inside the focusing electrode (13), and having a diverging force in the vertical direction greater than its diverging force in the horizontal direction inside the anode electrode (14), by applying a focus voltage to the focusing electrode (13) and the first field correction electrode (15) and applying an anode voltage higher than the focus voltage to the anode electrode (12) and the second field correction electrode (16).

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 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.
