Abstract: A deflection yoke for a cathode ray tube includes a core of magnetic material having front and back end portions, a front crown having a substantially flat outer surface normal to the core member axis and a slotted outer circumferential surface, a back crown member having a slotted surface normal to the core member axis, and a plurality of wire turns toroidally wrapped about the core and front and back crown members with the front crown member having a single layer of wire turns and the back crown member having a first layer at wire turns extending radially and added layers of wire turns extending non-radially to the front crown member. A process for fabricating a deflection yoke includes selecting and affixing crowns to a core member and wrapping wire turns thereon to include a single front layer and multiple back layers.

Abstract: A cathode ray tube convergence system includes a cathode ray tube with a plurality of electron beam sources formed to provide electron beams which are underconverged inside of and converged outside of the screen of the tube and a deflection yoke associated with the cathode ray tube and having horizontal deflection windings effecting convergence at the outer ends of the horizontal axis of the cathode ray tube screen.
