Deflection device for use in a color cathode-ray tube |
摘要 |
A deflection device for use in a color cathode-ray tube, which has a pair of horizontal deflection coils for generating a pincushion-shaped horizontal deflection magnetic field, a pair of vertical deflection coils for generating a barrel-shaped vertical deflection magnetic field. The deflection device also having a pair of correction coils each of which being located at a distance of 10 mm or less from a plane containing the center and vertical axes of the device, a current flowing through each correction coil in synchronism with, and in a direction opposite to, the currents flowing in the horizontal deflection coils. The deflection device may also include a second pair of correcting coils, each of which being located adjacent to the first pair of correcting coils and arranged in a similar arrangement relative to the plane defined by the center and vertical axes.
