Deflection yoke and yoke core used for the deflection yoke |
摘要 |
The present invention provides a deflection yoke for deflecting an electron beam emitted from an electron gun of a CRT (cathode ray tube). The deflection yoke is mounted on the CRT at a position between a neck tube having a small diameter section and a funnel having a large diameter section of the CRT. The deflection yoke comprises a horizontal deflection coil for deflecting the electron beam in a horizontal direction in the CRT, a vertical deflection coil for deflecting the electron beam in a vertical direction in the CRT, and a yoke core having a cone shape with a large diameter part at one end thereof in a side of the funnel and a small diameter part at another end thereof in a side of the neck tube to allow the yoke core to cover the horizontal and vertical deflection coils. The yoke core is made of a molded magnetic material cured by heating. The molded magnetic material includes a binder comprising a resin and a magnetic powder treated with a surface treatment agent comprising a compound having an aminoquinone group as a constitution unit.
