摘要： Disclosed is a deflection yoke mounted around a glass bulb of a CRT so as to cover a predetermined area of the glass bulb. The predetermined area is where an outer shape of the glass bulb smoothly goes from circular to substantially rectangular along a tube axis of the CRT. The deflection yoke includes a horizontal deflection coil disposed in a shape to fit with the outer shape of the glass bulb, and a funnel-shaped ferrite core disposed to surround the horizontal deflection coil. The inner shape of the ferrite core is circular throughout a length of the ferrite core.

摘要： In a cross-section including a tube axis, assuming that T1 represents a thickness of a funnel at a point on an outer circumferential surface of the funnel, which is placed at the same position in a tube axis direction as that of an end of a horizontal deflection coil on a phosphor screen side, and T2 represents a thickness of the funnel at a point on the outer circumferential surface of the funnel, which is placed at the same position in the tube axis direction as a position 7 mm away from the end of the horizontal deflection coil on the phosphor screen side to the phosphor screen side along the tube axis, the funnel includes at least one cross-section including the tube axis satisfying a relationship: T2/T1≧1.18. Owing to this, cone halation can be prevented while an X-ray leakage amount is limited to a predetermined value or less.

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： An insulating frame of a deflection yoke is fixed to a funnel with a metal band and a metal screw. A partition formed so as to be integrated with a holder holding a magnet ring of a CPU includes a first partition provided on a first axis so as to hide the metal screw when the deflection yoke is seen from the holder side along a tube axis, and a second partition provided on a second axis orthogonal to the first axis. A height H1 of the first partition, a height H2 of the second partition, a minimum height Hmin of the partition, a height HM of a pull of a magnet ring on a side closest to the deflection yoke, and an outer circumferential edge diameter RM of the magnet ring excluding the pull satisfy relationships: H1>H2, HM−H2>10 mm, and Hmin>RM. Because of this, a discharge between a metal band and a metal screw that fix the deflection yoke, and a velocity modulation coil can be prevented without decreasing the operability of the rotation adjustment of the magnet ring of the 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 coil for deflecting an electron beam emitted from an electron gun is provided outside a cathode-ray tube in which the electron gun is housed, and a phosphor screen is formed. The cathode-ray tube further includes a velocity modulation coil for modulating a horizontal scanning velocity of an electron beam, a first magnetic substance surrounding an outer circumference of the cathode-ray tube from outside the velocity modulation coil, and a second magnetic substance surrounding the outer circumference of the cathode-ray tube between the deflection coil and the first magnetic substance. Because of this, the sensitivity of velocity modulation can be enhanced effectively with a simple configuration while deflection distortion is prevented.
