发明名称 Method of manufacturing an electro-magnetic deflection unit for a cathode ray tube.
摘要 <p>An electro-magnetic deflection coil of the incomplete saddle-type (that is to say, with a flangeless narrowest - or rear - end) is wound against the inside of a funnel-shaped support 14. The support 14 is opposite the windows of the coil parts 19 has recesses 25 through which axially extending guide elements 26, 27 are passed inwards during the winding process in order to support the circumferentially extending turn segments of the coil parts 19 on the rear side. After winding, each coil part 19 is formed to a coherent unit by means of a thermal treatment and the guide elements 26, 27 are removed.</p>
