摘要： U.S. Pat. No. 3,684,920 issued on Aug. 15, 1972 and based on U.S. Patent Application Serial No. 37,668, filed May 15, 1970, describes a transistor deflection circuit employing an output stage of class B, push-pull complementary symmetry type and a Miller integrator approach for the sawtooth wave generation. This invention describes a modification to the discharge circuitry thereof to improve the vertical deflection stability in the presence of spurious pulses which tend to undesirably and randomly trigger and/or retrigger the discharge switch. An additional ''''blanker'''' transistor is employed to sense the voltage across the vertical yoke winding so as to bypass the spurious signals away from the discharge switch during the vertical retrace interval when the danger exists that the deflection circuits will be falsely triggered.

摘要： Transistorized vertical deflection circuit employs output stage of class B, push-pull, complementary symmetry configuration with vertical yoke winding halves serially connected in output circuit. Miller integrator approach is used for sawtooth wave generation, with feedback waveform derived from yoke current sampling resistor. Discharge transistor is responsive to feedback of flyback pulses developed across serially connected yoke winding halves. Apparatus disposed between winding halves introduces modulated horizontal deflection frequency current components in winding halves for pincushion correcting purposes. One winding half of vertical deflection yoke is shunted by a capacitor of a value selected to introduce cancellation of horizontal deflection frequency components across yoke/pincushion circuitry, in order to minimize feedback of interlace-disturbing horizontal components in pincushion corrected vertical deflection circuit.
