Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
105 words
IN A DISPLAY DEVICE HAVING A DEFLECTABLE ELECTRON BEAM AND A SWEEP CIRCUIT FOR DEVELOPING SWEEP AND RETRACE CONTROL SIGNALS, A DEFLECTION SYSTEM COMPRISING: A SOURCE OF DIRECT CURRENT POTENTIAL; DEFLECTION MEANS; FIRST SWITCH MEANS CONNECTED IN SERIES WITH SAID DEFLECTION MEANS AND CONNECTED WITH SAID SOURCE, AND CONTROLLED BY SAID SIGNALS TO CONDUCT DURING THE SWEEP SIGNAL; A CAPACITOR CONNECTED IN PARALLEL WITH SAID DEFLECTION MEANS AND FIRST SWITCH MEANS, ACROSS SAID SOURCE; AND SECOND SWITCH MEANS OPERATIVELY CONNECTED WITH SAID SOURCE AND CAPACITOR AND CONTROLLED BY SAID SWEEP AND RETRACE SIGNALS TO CONTROL THE CHARGE OF SAID CAPACITOR FROM SAID SOURCE DURING RETRACE.
