たことを特徴とする偏向ヨーク装置。 A three-electron gun for in-line color cathode ray tubes, which has a pair of saddle-shaped horizontal deflection coils and a toroidal-wound or saddle-shaped vertical deflection coil connected in parallel, and in which the horizontal deflection magnetic field is pincushion-shaped and the vertical deflection magnetic field is barrel-shaped. In the self-convergence type deflection yoke device, two drum-shaped cores are integrated by bonding one magnet magnetized in the thickness direction between their ribs, and a controlled coil is wound around each drum-shaped core, respectively. Corresponding control windings are wound on these controlled coils via insulating bobbins to form a saturable transformer, one of the controlled coils is connected in series with one of the horizontal deflection coils, and one of the controlled coils is connected in series with one of the horizontal deflection coils. The other controlled coil is connected in series with the other horizontal deflection coil, the two control coils are connected in series such that their generated magnetic fields are in opposite directions, and the series-connected control coil is further connected to the control coil. An inductor is connected in series and a resonant capacitor is connected in parallel to the series circuit of the control coil and inductor, the series circuit of the control coil and inductor is connected in series with the vertical deflection coil, and the series circuit of the control coil and inductor is connected in series. A deflection yoke device characterized in that the oscillation frequency of the combined inductance and the resonance capacitor is selected to be about half of the horizontal frequency.
