发明名称 Deflection yoke and mis-convergence correction method for color cathode-ray tube
摘要 An inline type color cathode-ray tube deflection yoke applies a deflecting magnetic field to electron beams from a neck portion of a valve accommodating three electron guns toward the funnel portion of the valve. The deflection yoke is provided with a vertical deflection coil, auxiliary coils serially connected to the vertical deflection coil, and a U-shaped magnetic member around each of both leg portions of which the auxiliary coils are wound. The U-shaped magnetic member is arranged so that the leg portions face the neck portion.
