Electro-optical circuitry having improved response speed

Claim 1

AN ELECTRO-OPTIC GATE CIRCUIT COMPRISING IN COMBINATION A VOLTAGE SUPPLY, A FIRST LIGHT RESPONSIVE RESISTOR, A CURRENT LIMITING RESISTOR, AND A LIGHT PRODUCING MEANS CONNECTED IN SERIES; SAID FIRST LIGHT RESPONSIVE RESISTOR HAVING A HIGH RESISTANCE WHEN DARK AND A LOW RESISTANCE WHEN ILLUMINATED, SAID LIGHT PRODUCING MEANS ADAPTED TO BE ACTIVATED BY A CRITICAL VOLTAGE; A SECOND LIGHT RESPONSIVE RESISTOR POSITIONED TO RECEIVE LIGHT FROM SAID LIGHT PRODUCING MEANS, SAID SECOND LIGHT RESPONSIVE RESISTOR REQUIRING A CERTAIN PERIOD OF TIME (X) AFTER BEING ILLUMINTED TO CHANGE STATE; MEANS FOR ILLUMINATING SAID FIRST LIGHT RESPONSIVE RESISTOR TO CAUSE IT TO ASSUME ITS LOW RESISTANCE STATE, THEREBY ACTIVATING SAID LIGHT PRODUCING MEANS; A CAPACITOR SHUNTING SAID CURRENT LIMITING RESISTOR, WHEREBY THE VOLTAGE APPLIED TO SAID LIGHT PRODUCING MEANS IS INCREASED DURING PERIODS WHEN SAID FIRST LIGHT RESPONSIVE RESISTOR IS CHANGING FROM HIGH TO LOW RESISTANCE; AND WHEREBY THE INTENSITY OF THE INITIAL LIGHT OUTPUT IS GREATER THAN THE STEADY STATE LIGHT OUTPUT; THE MAGNITUDE OF SAID SHUNTING CAPACITOR BEING SUCH THAT THE LIGHT INTENSITY REACHES ITS STEADY STATE VALUE IN A TIME PERIOD SUBSTANTIALLY EQUAL TO THE TIME PERIOD (X).
