摘要： A deflection yoke device comprises a convergence correction circuit connected between a vertical deflection coil and correction coils. The convergence correction circuit includes a first, second and third impedance elements connected in parallel and at least two diodes. The diodes are connected in series in the same direction and respond to a vertical deflection current of the vertical deflection coil to regulate a current flowing through the correction coils to thereby correct the YH mis-convergence.

摘要： A horizontal deflection circuit for a CRT supplies an exciting current in such a way that flyback voltages including both a positive voltage and a negative voltage as components are generated in horizontal deflection coils of a horizontal deflection yoke, respectively, during energizing the horizontal deflection yoke to provide a magnetic field for horizontal scans. A positive electric field of VLF and a negative electric field of VLF which are generated in the horizontal deflection yoke by the respective flyback voltages cancel each other to decrease a composite electric field of VLF emitted from the horizontal deflection yoke. This prevents unwanted radiation leaking to the outside of the a CRT display.

摘要： A deflection yoke for a picture tube of a projection color television receiver set has a solenoid-shaped auxiliary coil arranged adjacent to a core of the deflection yoke with a center axis of the auxiliary coil being aligned to a center axis of the deflection yoke. A vertical deflection current or a horizontal deflection current is supplied to the auxiliary coil. An electron beam is deflected by a magnetic field generated by the current of the auxiliary coil so that a raster formed on a face plate of the picture tube is deformed. The raster is deformed to such an extent that it has a correct shape when it is projected on a screen.
