摘要： A diode modulator circuit which is adapted to supply an acceptable S-correction of the S-linearity error of the line scanning of a picture tube (CRT) at substantially different line scan widths. A known diode modulator has two loops. The first loop includes a series arrangement of a line deflection coil (LD) and an S-capacitor (CS), which series arrangement is arranged in parallel with a first flyback capacitor (CF1) and a first diode (D1). The second loop includes a modulator coil (LB) arranged in parallel with a second flyback capacitor (CF2) and a second diode (D2). The two loops are arranged in series. An inner-pincushion capacitor (CSM) is arranged in a common path in which the line deflection current (Id) and a modulator current (Ib) flowing through the modulator coil (LB) flow in opposite directions. The amount of S-correction depends on the values of the S-correction capacitor (SC) and the inner-pincushion capacitor (CSM). The S-capacitor (CS) has been omitted in the subject diode modulator. In this way, the amount of S-correction at minimal scan width will be zero because the common current (Im) flowing in the common path is zero if the diode modulator is in equilibrium. The diode modulator according to the invention can thus cope with picture tubes (CRT) which require a very low amount of S-correction at a small scan width without the need for an additional capacitor (CS2) and a thyristor switching circuit (T) to activate the additional capacitor (CS2) to lower the amount of S-correction at the small scan width.

摘要： A nonlinear inductor for a CRT line timebase circuit comprises a bobbin carrying an inductive coil 41 and a first permanent magnet adjacent the coil. A second permanent magnet is positioned and oriented relative to the first magnet in such a manner that the magnetic field generated by the nonlinear inductor is substantially reduced. Because the second magnet is integral, the nonlinear inductor occupies the same printed circuit board area as a conventional nonlinear inductor. Furthermore, because the second magnet is oriented to substantially cancel the magnetic field, no additional magnets are required for deflecting the magnet field away from the CRT.

摘要： A saturable reactor having a pair of series coils is attached to the outside surface of the cores of the vertical deflecting coils where the series coils are connected in series with a parallel connection of the horizontal deflecting coils. Each of the pair of coils of the saturable reactor is wound around a drum core which is magnetically biased by means of a permanent magnet. The saturable reactor is positioned so that leakage flux from the vertical deflecting coils is led into the drum cores, thereby changing the inductance of the pair of coils in accordance with the degree of vertical deflection. The horizontal deflecting currents flowing through the horizontal deflecting coils thus controlled to chage the width of raster providing a trapezoidal raster which is needed for projecting a TV picture on a large screen.

摘要： A linearity inductance and a side pincushion correction inductance are wound on outer leg core portions of a single E-core. A magnet biases the linearity inductance core portion for saturating that portion each horizontal deflection cycle for producing a linearity corrected horizontal deflection current. A high reluctance path for flux mutually linking both the linearity and side pincushion correction windings is provided by the E-core configuration. The portion of the flux generated by the side pincushion correction winding that does flow in the linearity winding core portion compensates for undesirable vertical rate changes in the magnetic bias of the linearity winding core portion.
