摘要： A cathode ray tube deflection unit comprising a field coil system with two diametrically opposite field deflection coils and a line coil system with two diametrically opposite line deflection coils. Each coil has a front end segment (15, 18), a rear-end segment (16, 19) and conductors (17, 20) extending between such segments. In order to prevent rotation of the horizontal lines of the raster on the CRT display screen with respect to the horizontal axis, which rotation is caused by tolerance errors in alignment of the two coil systems, a pair of plate-shaped parts (21, 21') of soft magnetic material are arranged respectively extending across the front end segment (15, 15') of the respective line deflection coils (11, 11') in positions coinciding with diametrically opposite vertices of a rectangle whose diagnonals intersect substantially on the longitudinal axis of the deflection unit, and at which positions a portion of the front end segment of a line deflection coil overlaps a portion of the front end segment of a field deflection coil.

摘要： A deflection yoke apparatus has a pair of horizontal and a pair of vertical deflection coils, a coil separator therebetween, and a funnel-shaped deflection core which provides a magnetic path for magnetic flux generated by the deflection coils. A pair of auxiliary coils are arranged at diametrically opposed positions outside the deflection core, and may be energized by the horizontal deflection current supplied to the horizontal deflection coils. The magnetic field generated by the auxiliary coils at least partially compensates the external magnetic leakage field which is radiated outside the deflection core by the horizontal deflection coils. The auxiliary coils have rod-shaped magnetic cores which are in magnetic flux coupling relationship with the smaller end of the deflection core. Leakage flux compensation is thereby achieved with minimal affect on the deflection fields and with low power dissipation in the auxiliary coils.

摘要： A line output transformer with compensation for any alternating electric field in band 2, i.e., the horizontal deflection frequency band (AEF2). The output transformer comprises a ferromagnetic core with at least one leg and at least one high voltage winding arranged on a leg of the core and magnetically coupled to the core. A rectifier and a capacitor are coupled to the high voltage winding for generating a smoothed high DC voltage. A high voltage conductor is electrically connected to the rectifier and the capacitor for applying the high DC-voltage to an electrode of a cathode ray tube. In order to reduce the value of the AEF2, the high voltage conductor includes a first portion that is magnetically coupled to the core. Preferably, the first portion of the high voltage conductor includes at least one turn that surrounds a leg of the core.

摘要： A cathode ray tube electromagnetic deflection unit comprising a support (4) having a flange (8) at its constricted end (5) which has a tangential groove into which radial grooves (14) merge. Two sets of deflection coils (18, 19) are wound on the support (4), the turns thereof running through the radial grooves (14) and the turns of one set bending into the tangential groove. The coils of the coil system 18 are for line deflection, and the two halves thereof are wound in the opposite winding sense and are energized during operation in such a manner that the highest voltage in both coils occurs at the coil turns adjacent plane of separation between the two coils and the lowest voltage occurs at the coil turns most remote from such plane of separation.
