Abstract: Series connected first to fourth reactor coils are wound on a core and connected in series with a horizontal deflection coil. A coil is also wound on the core and connected in series with a vertical deflection coil. The core is provided with two permanent magnets and magnetic bias is applied to the first to fourth reactor coils. A total inductance of first to fourth reactor coils is controlled by a vertical deflection current passing through the coil, and thereby, a correction amount of an amplitude of a horizontal deflection current is changed.

Abstract: Linearity correction apparatus for a raster scanned cathode ray tube display device is presented. The apparatus comprises first means (16) for generating a correction signal to correct an asymmetric non linearity in a sawtooth electron beam line deflection current. The line deflection current is generated by a line timebase circuit for energising electromagnetic electron beam deflection coils of the cathode ray tube. The apparatus further comprises second means (70,90,91) cooperative with the first means (16) and responsive to a change in line timebase frequency for compensating a variation in the correction signal generated by the first means (16) in response to said change in line timebase frequency.

Abstract: A scanning CRT control system is disclosed in which horizontal sync pulses are used to develop a pulse signal that provides an input to a transformer circuit also receiving a relatively low DC power supply input signal. The transformer circuit develops a very high DC voltage connected to a CRT screen while also providing a relatively lower voltage power supply signal that is utilized to develop the power supply signal provided to a video driver that controls beam excitation for the CRT. A compensation circuit is provided between the transformer circuit and a power supply terminal of the video driver such that a compensating signal is provided at the transformer circuit in accordance with each horizontal video scan line. The compensating signal has a frequency corresponding to the horizontal sweep frequency and a magnitude that varies in accordance with the average current loading of each individual horizontal scan line. In this manner the compensating signal will cause a variation in horizontal beam positioning so as to maintain horizontal orientation between different sequential horizontal scan lines regardless of the average beam current intensity of each of the horizontal scan lines. Preferably, the compensation circuit comprises a parallel resistor and capacitor connected in series between an output terminal of the transformer and the power supply terminal of the video driver.

Abstract: A horizontal deflection circuit in a television device comprises a circuit for generating a saw-tooth waveform current for horizontal deflection, a horizontal coil supplied with the saw-tooth waveform current thus generated, a saturable reactor type linearity coil having a winding connected in series with the horizontal deflection coil, and a circuit for substantially supplying a correction current to the winding of the linearity coil. The correction current thus supplied varies in response to a temperature variation so that the inductance value of the linearity coil will become constant irrespective of the temperature variation.

Abstract: A television kinescope deflection circuit having improved linearity includes a deflection winding coupled in series with a first capacitor. A deflection switch and retrace capacitor are coupled across the serial combination of the deflection winding and first capacitor. The first capacitor responds to the deflection current to form a linearizing signal which modifies the flow of deflection current to provide S-correction. The linearity correction is improved by a series-resonant circuit coupled in parallel with the first capacitor and tuned to the second harmonic of the deflection frequency.

Abstract: In a television receiver, a saturable transformer has three windings, one being in series with a horizontal deflection coil to introduce a parabolic reactance variation to correct for side pincushion distortion. An adjustable correction circuit includes a transistor integrator for producing in another winding of the saturable transformer a vertical parabolic current. The last winding of the saturable transformer is coupled through a pair of switching diodes to a pair of variable inductors. The diodes conduct alternately at the beginning and end of the vertical scanning period. The variable inductors may be mounted coaxially with a common movable core to allow inverse side correction, or may be mounted separately with separate movable cores to allow independent side correction.
