摘要：
A deflection yoke for a cathode ray tube can correct both the pincushion distortion at the upper and lower edges of the screen and the misconvergence of the screen at the same time by the deflection yoke itself without the need for a correction magnet. The deflection yoke comprises a saddle shaped horizontal deflection coil 1, a saddle shaped vertical deflection coil 2 located outside the horizontal deflection coil 1, and a high permeability core 3 located outside the vertical deflection coil 2. The core 3 has notch portions 7 at the center parts of the upper and lower portions of the screen side end.
