Abstract:
A deflection yoke for use in a color cathode ray tube, comprising:a horizontal deflection coil;a vertical deflection coil;an annular core;a first magnetic coil pair consisting of a first coil and a second coil; anda second magnetic coil pair consisting of a third coil and a fourth coil;wherein said first magnetic coil pair and said second magnetic coil pair are so positioned as to be opposite horizontally to the rear end of said deflection yoke; said first and fourth coils are connected in series to constitute a first electric coil pair for generating magnetic fields in mutually reverse directions, while said second and third coils are connected in series to constitute a second electric coil pair for generating magnetic fields in mutually reverse directions; and said first and second electric coil pairs are connected in series to generate magnetic fields in mutually reverse directions; wherein said first and second electric coil pairs in combination with a variable resistor constitute a bridge circuit, and said bridge circuit is connected in series to said vertical deflection coil.
