Claim 1
Independent Claim
181 words
A CIRCUIT ARRANGEMENT FOR PRODUCING A CURRENT HAVING A SAW TOOTH SHAPED CURVED FOR THE DEFLECTION OF AN ELECTRON BEAM OF A CRT WHEREIN THE RADIUS OF CURVATURE OF THE SCREEB IS GREATER THAN ITS DISTANCE FROM THE CENTER OF DEFLECTION, COMPRISING AN OUTPUT CIRCUIT HAVING DEFLECTING COILS PRESENTING AN OHMIC LOAD WITH AN INDUCTIVE COMPONENT FOR THE SAW TOOTH CURRENT, TUBE MEANS CONNECTED TO SAID OUTPUT CIRCUIT AND HAVING AN ANODE AND A CONTROL GRID FOR GENERATING A SAW TOOTH CONTROL VOLTAGE; CAPACITIVE VOLTAGE DIVIDER MEANS INCLUDING TWO CAPACITORS CONNECTED TO THE TUBE ANODE FOR PREDISTORTING THE SAW TOOTH CONTROL VOLTAGE WITH FREQUENCY DEPENDENT NEGATIVE FEEDBACK WHICH IS FED TO THE CONTROL GRID; A VARIABLE LINEARITY REGULATOR HAVING A TAPPING POINT AND CONNECTED TO A TAPPING POINT OF THE CAPACITIVE VOLTAGE DIVIDER BETWEEN THE TWO CAPACITORS AND A SUBSTANTIALLY FIXED VOLTAGE FOR CORRECTING THE TANGENTIAL DISTORTION; AND AT LEAST ONE CIRCUIT ELEMENT MEANS CONNECTED WITH SAID REGULATOR TO BRING ABOUT AN ADDITIONAL PREDISTORTION OF THE CONTROL VOLTAGE SO THAT WHEN THE LINEARITY REGULATOR IS SHORT-CIRCUITED THE ADDITIONAL PREDISTORTION IS MINIMAL.
