いて、電子ビームの放射軸上左右に水平偏向コイ
ルによる水平偏向磁界と同方向の磁界を発生し、
かつその磁界の大きさを可変し得るコイル手段を
付加したことを特徴とする偏向ヨーク。 In the deflection yoke used in color cathode ray tubes, a magnetic field is generated in the same direction as the horizontal deflection magnetic field by the horizontal deflection coil on the left and right sides of the emission axis of the electron beam.
A deflection yoke characterized in that it is further equipped with a coil means that can vary the magnitude of the magnetic field.
