  • Deflection yoke with a triangular magnetic-field leakage canceling coil
    Patent number: 5404121
    Abstract: A deflection yoke is mounted with a leaked magnetic-field canceling coil installed on a screen portion for attenuating externally emitted leakage magnetic field, using a horizontal deflection coil. The leaked magnetic-field canceling coil includes a bottom side in parallel with the surface of the screen portion of a coil separator contacting the horizontal deflection coil, left and right sides extending from both ends of the bottom side to an apex peak point to be set in the range of 1/4 of the length of the bottom side from the alternative one end of the bottom side; and and a first and second diagonal sides straightly connecting one end of the left and right sides to the right and left ends of the bottom side, respectively.
