Cathode ray tube having resistor deflection control

Claim 1

IN A CHARACTER GENERATING SYSTEM, A CATHODE RAY TUBE, ANALOG SIGNAL SYNTHESIZER MEANS COMPRISING A PLURALITY OF CIRCUIT UNITS FOR SELECTIVE OPERATION IN THE GENERATION OF VARIOUS CHARACTERS, CHARACTER DESIGNATING CONTROL MEANS CONNECTED TO SAID SYNTHESIZER MEANS TO CONDITION SAID CIRCUIT UNITS FOR OPERATION SELECTIVELY, EACH SAID CIRCUIT UNIT COMPRISING A LEVEL GENERATOR, SAID LEVEL GENERATOR COMPRISING A LEVEL CONTRL TRANSISTOR HAVING AN ON-OFF CONDITIONING INPUT CONNECTED TO ITS BASE AND RESPONSIVE TO SAID DESIGNATING CONTROL MEANS AND AN EMITTER-COLLECTOR CIRCUIT INCLUDING A PLURALITY OF CONTROL BRANCHES DCONNECTED IN PARALLEL TO THE EMITTER OFSAID TRANSISTOR, EACH SAID BRANCH INCLUDING AN EMITTER LOAD FOR ESTABLISHING A PREDETERMINED EMITTER CURRENT THROUGH SAID TRANSISTOR BY AND DURING ACTIVATION OF SAID BRANCH, TIMING SIGNAL DISTRIBUTOR MEANS CONNECTED TO EACH OF SAID LEVEL GENERATORS FOR ACTIVATING SAID CONTROL BRANCHES IN SUCCESSION, AND CONTROL MEANS FOR SAID CATHODE RAY TUBE CONNE TED TO BE RESPONSIVE TO SAID LEVEL GENERATORS FOR CAUSING THE ELECTRON BEAM OF SAID CATHODE RAY TUBE TO EXECUTE OPERATIONS IN ACCORDANCE WITH THE OUTPUT OF SAID SYNTHESIZER MEANS.
