Deflection yoke apparatus with means for reducing unwanted radiation. |
摘要 |
<p>A deflection yoke apparatus comprising pairs of horizontal and vertical deflection coils, a coil separator located between both coils, a deflection core forming a magnetic path for a magnetic flux generated from both deflection coils and auxiliary coil means which is arranged at at least one of positions in a vertical deflection direction outside said deflection core, wherein a horizontal deflection current is supplied to this auxiliary coil means and a magnetic field generated from said auxiliary coil means reduces an intensity of externally leaking magnetic field which radiates outside said deflection core when a horizontal deflection current is supplied to said horizontal deflection coils.</p> |
