摘要:
In direct-wound yokes, such as toroids, where individual wires are wound from end-cap to opposite end-cap along the core inner surface, the problem of layers of wire wound above and between adjacent wires forcing these wires out of place in a random manner is overcome by coating the inner surface of the core with an adhesive that increases friction and thus resists wire movement. The adhesive, applied in liquid form, remains tacky indefinitely, thus allowing turns to be removed and the parts reused if desired.

An improved electromagnetic deflection yoke core comprising an annular member of ferromagnetic material in which a plurality of slots are disposed along the interior perimeter thereof and are distributed in a given quadrant with respect to horizontal and vertical orthogonal axes which divide the core into four equal quadrants, the disposition or location of the slots being in accordance with an approximate cosine distribution about a 45* diagonal to said orthogonal axes.

Projecting points on a yoke core are utilized to permit the winding of a number of separate and distinct coils as a single coil capable of subsequent separation into said separate coils. After the winding of a first coil the wire is snubbed against a first of such projecting points and the winding operation is stopped. The yoke core, however, is continuously rotated, dragging the wire across the yoke core until a second projecting point is reached, at which time the winding of a second coil is commenced.

The active field producing conductor turns on the inside generally cylindrical core surface of a multilayer toroidal deflection yoke are wound in one direction, e.g., clockwise. The return conductors on the outside of the core are wound in a flyback manner for enabling conductors to be placed in a second layer between the conductors of the first layer for forming a higher conductor distribution density for a first coil or for interleaving the conductors of a second coil between the conductors of the first coil. The two layers may thus be wound over a large angular portion of the core without stopping the winding machine for the cutting or tying of conductors within each coil.

In a toroidal type deflection coil for use in a cathode ray tube of the type comprising a funnel shaped magnetic core and a coil wound about the core to create a magnetic field having different distributions at the fore and rear edges of the core, portions of the peripheries of the fore and rear edges of the core on which the coil is wound take the form of curves of different radii of curvature.
摘要:
A cathode-ray tube deflection system includes a triad-type cathode-ray tube and a toroid-type deflection yoke having horizontal and vertical axes with first and second horizontal windings symmetrical to the horizontal axis in mirror image of one another about the vertical axis and first and second vertical winding symmetrical to the vertical axis in mirror image of one another about the horizontal axis and said first and second horizontal and vertical windings each including a flux altering means for enhancing vertical convergence of horizontal trace lines. The deflection yoke is formed by a process wherein a core of magnetic material is wrapped with wire turns applied in toroidal fashion to form first and second horizontal windings and first and second vertical windings advanced in opposite circumferential direction to form a mirror image relationship. Also, ''''ringing'''' is inhibited by circuitry wherein a specific terminal of each of the horizontal and the vertical windings associated with the start of electron beam scanning of the cathode-ray tube is connected to a potential reference level while the other extremities of the horizontal and vertical windings are connected to a source of deflection signals whereby undesired distortions appearing on the trace lines of the viewing screen are minimized.
