  • Method of manufacturing a deflection unit
    Patent number: 5355578
    Abstract: Method of manufacturing a deflection unit comprising a set of diametrical deflection coils, in which method the coils are placed on a jig which supports each coil at a plurality of locations and in which a coil support of synethic material is urged against the free surface of each coil. The coils are mechanically anchored by means of, for example an ultrasonic welding process in which the locations of the coil support situated opposite supported locations of the coils are softened and pressed into the coils. The coils are not deformed in that case and their mutual position defined by the jig is accurately maintained.
