摘要

Improvements in electronic beam suppression circuits for television receivers, of the type employing a kinescope having an electronic beam, whose receiver incorporates a deflection circuit for deflecting said electronic beam in a direction of two mutually perpendicular directions, said circuit being deviation of the type comprising first and second active devices coupled in an oscillating configuration to allow a sawtooth sling shape having a relatively rapid discharge time determined by the conduction of one of said active devices during a back-off interval associated with said bypass circuit, characterized in that each circuit is provided with a first device responsive to the conduction of said first active device during said retrace interval to provide a signal determining said conduction and, therefore, said interval of recoil, you an additional active device having an input, an output and a common electrode and being sensitive to the feeding of a signal to said input electrode to have a low impedance between said output and common electrodes, with a second device that couples said electrode input to said first device for making said additional active device had said low impedance state during said receding interval, with a third device coupling said output electrode of said active electrode to said kinescope capable of causing said electronic beam to be disconnected from said electrode. Said kinescope during said retraction interval. (Machine-translation by Google Translate, not legally binding)
