Abstract (en)
[origin: US4700164A] The deflecting yoke for a cathode-ray tube of the invention includes a magnetic circuit enveloping the back flares of the deflecting coils, which are folded down into the extension of the central parts of these coils. The end of the back part of the magnetic circuit extends radially inwards until it substantially makes contact with a neck portion of the cathode-ray tube.
