This innovative apparatus utilizes a flyback transformer with a secondary winding divided into multiple parts by at least a diode. The primary winding connects to a variable voltage divider circuit, allowing for the adjustment of the flyback pulse voltage. This configuration enables the application of a variable pulse voltage to the focus capacitor, effectively regulating the focus voltage and improving image clarity.

The second significant patent is an **automatic gain control circuit**. This invention aims to stabilize the black level of composite video signals by producing a signal with a maximum amplitude that corresponds to the pedestal level of the video signal. By removing the horizontal synchronizing signal, an automatic gain control signal is derived, which in turn controls high-frequency and intermediate frequency amplifiers to maintain a constant pedestal portion. This innovation ultimately achieves a stabilized contrast, enhancing the overall quality of the visual output.
