摘要： A cathode-ray tube comprising an electron gun (4) disposed in the neck portion (3) of a funnel (2), a deflection yoke (5) having a horizontal deflection coil (51) and a vertical deflection coil (52) mounted on the outer surface of the funnel (2) in a position closer to the front panel than the electron gun (4), and a speed modulation coil (6) mounted on the outer surface of the neck portion (3). The speed modulation coil (6) is so disposed that the end part thereof on the front panel side is closer to the electron gun (4) than the end part of the horizontal deflection coil (51) facing the electron gun (4) and closer to the front panel side the end part of the electron gun (4) facing the front panel. A desired speed modulation effect can be attained because the speed modulation magnetic field (28) of the speed modulation coil (6) does not interfere withe the deflection magnetic field and can be prevented from disappearing by causing by causing an eddy current in a top unit (27).

摘要： Deflector for cathode-ray tube comprising a pair of horizontal deflection coils (3) and a pair of vertical deflection coils (4), the two pairs being in the shape of a saddle and isolated one from the other by a separator (2), a frustoconical shaped ferrite ring (5) at least partially covering the deflection coils, the deflector being characterized in that it includes to the rear of the deflection coils, between the horizontal and vertical deflection coils, four field shapers (20) placed symmetrically with respect to the axes of symmetry of the deflector. These shapers are placed so as to increase the amplitude of the second harmonic of the potential of the vertical deflection field without affecting the fundamental of the said potential in order to act on the phenomena of coma appearing on the horizontal edges of the image formed on the tube screen.

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.
