DEFLECTION YOKE AND CATHODE-RAY TUBE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a deflection yoke and a cathode-ray tube device capable of easily surely executing the correction of mis-convergence in a less man-hour. SOLUTION: A correction coil unit 44 has winding parts 442, 443 in which two coil wires are wound at certain intervals on the outside of a bobbin 441. A female screw is installed across the ends in the shaft direction of the bobbin 441 on the inside of a hollow portion 441e of the bobbin 441. Magnetic cores 444, 445 in which a male screw corresponding to the female screw is installed on the peripheral surface are inserted into the hollow portion 441e. The magnetic cores 444, 445 are inserted into the bobbin 441 so that edges having different polarities are faced with each other inside the bobbin 441. COPYRIGHT: (C)2005,JPO&NCIPI
