RADIATION DEPRESSING APPARATUS FOR DEFLECTION YOKE

摘要

The apparatus removes the leakage magnetic flux formed around the screen during operation of the horizontal deflection coil to prevent the unnecessary low radiation of magnetic flux caused by the leakage magnetic flux. The apparatus comprises drum cores (21,22) formed by two stages and wound by demagnetising coils (23,24). The certain part of the drum cores (21',22') without wounding the coil is prolonged toward the front housing (12) part.
