CORE FOR DEFLECTING YOKE AND DEFLECTING YOKE

摘要

A core for a deflecting yoke for a cathode-ray tube comprising a display panel, a funnel section, and a neck section and a deflecting yoke. The core has a generally circular open end face on the neck section side. The internal periphery of the open end face on the funnel section side is generally rectangular. The rectangular shape corresponds to the shape of the display panel. Each side of the rectangle has a generally straight line section. A deflecting yoke provided with such a core contributes to an improvement in deflecting sensitivity and a reduction in power consumption. When a plurality of projecting are provided on the internal surface of the core, the envelope shape of the bottom faces of the groove sections between the projecting sections is generally rectangular.
