TH30356B - Curl deflection, saddle-like shape with a winding gap. - Google Patents

Abstract

Deflection yoke for cathode ray tubes including saddle-shaped vertical deflection coils And the horizontal deflection coils, shaped like a saddle Horizontal deflection coils, including winding turns That creates a pair of lateral sections with a winding between them that are spanned independently from the conductor wire, the lateral section with a winding gap for correcting the corresponding sections of coma tolerances and coherent examinations. The angle of the winding gap is positioned in the chosen Z-axis coordinate in the range between the Z-axis coordinate that determines the end of the cavity near the electron gun of the tube and the third Z-axis coordinate near the screen of the tube. It is approximately 10% of the channel length. Correction of Examination dislocation, horizontal coma discrepancy or coma discrepancy. Parabolic can be obtained without the use of field shaping components such as shafts or magnets.

1. The video display deflection device consists of a saddle-shaped deflection coil for producing a scanning e-field. Electron beam along the first axis of the cathode ray tube display. First deflection coil This includes a number of winding cycles to form pairs of lateral segments. Near the front end. With the aforementioned screen And the rear end periphery near the electron gun of the tube, the lateral part forms a channel for the free winding of the inter-conductor with a length determined by Distance between sections
