Bias technology and manufacturing method for electric wave bias display

摘要

Disclosed are deflecting yoke for electromagnetic deflection type cathode-ray tubes which comprises a compressively molded products consisting substantially of an iron powder or an iron-based alloy magnetic powder; an electrically insulating powdery resin; an organic metallic coupling agent; and an electrically insulating powdery inorganic compound; and a method for manufacturing it which comprises the steps of: mixing an iron powder or an iron-based alloy magnetic powder, an electrically insulating powdery resin and an organometallic coupling agent with one other; then mixing an electrically insulating powdery inorganic compound therewith; and compressively molding the prepared mixture. The deflecting yoke of the present invention has more excellent properties, as compared with conventional ferrite cores and dust cores. Moreover, the deflecting yoke of the present invention can restrain the temperature rise more satisfactorily than the conventional deflecting yoke. Further, the deflecting yoke of the present invention can be manufactured with extreme ease and is suitable for mass production.
