Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
143 words
A HORIZONTAL DEFLECTION DEVICE COMPRISING A HORIZONTAL DEFLECTION TRANSFORMER HAVING A PRIMARY WINDING, A CAPACITOR CONNECTED BETWEEN ONE END OF SAID PRIMARY WINDING AND A REFERENCE POTENTIAL, AN AMPLIFIER INCLUDING A TRANSISTOR HAVING A BASE ELECTRODE, AN EMITTER ELECTRODE, AND A COLLECTOR ELECTRODE, WITH A PAIR OF SAID ELECTRODES FORMING AN INPUT AND ANOTHER PAIR OF SAID ELECTRODES FORMING AN OUTPUT, WITH ONE OF SAID ELECTRODES BEING COMMON TO BOTH THE INPUT AND THE OUTPUT, THE OUTPUT OF SAID AMPLIFIER BEING CONNECTED ACROSS SAID PRIMARY WINDING AND SAID CAPACITOR, A HORIZONTAL DEFLECTION COIL CONNECTED TO SAID TRANSFORMER, A DAMPER DIODE CONNECTED IN PARALLEL WITH THE OUTPUT OF SAID AMPLIFIER, A SOURCE OF POTENTIAL, AND A BOOST DIODE CONNECTED BETWEEN ONE ELECTRODE OF SAID TRANSISTOR WHICH FORMS PART OF THE OUTPUT THEREOF AND SAID SOURCE OF POTENTIAL FOR BOOSTING THE VOLTAGE ACROSS SAID CAPACITOR.
