Claims

1. MEANS FOR STABILIZING THE OPERATING TEMPERATURE OF A SEMI-CONDUCTOR CHIP COMPRISING IN COMBINATION:

(A) ELECTRICALLY ENERGIZABLE HEAT GENERATING MEANS MOUNTED IN INTIMATE HEAT CONDUCTIVE RELATION WITH THE CHIP FOR HEATING THE CHIP;

(B) CIRCUIT MEANS ADAPTED TO CONNECT AN ELECTRICAL SOURCE TO SAID HEAT GENERATING MEANS;

AND (C) CONTROL MEANS INCLUDING TEMPERATURE SENSITIVE MEANS CONNECTED TO SAID CIRCUIT MEANS AND ADAPTED TO RESPOND TO CHANGES IN AMBIENT TEMPERATURE FOR CONTINUOUSLY CONTROLLING THE PROVISION OF ENERGIZING CURRENT FLOW THROUGH SAID HEAT GENERATING MEANS INVERSELY WITH RESPECT TO AMBIENT TEMPERATURE CHANGES, SAID TEMPERATURE SENSITIVE MEANS INCLUDING AN INTERCONNECTED POSITIVE TEMPERATURE COEFFICIENT RESISTOR MEANS AND NEGATIVE TEMPERATURE COEFFICIENT RESISTOR MEANS, SAID RESISTOR MEANS BEING SO PROPORTIONED AS TO VARY ENERGIZING CURRENT FLOW THROUGH SAID HEAT GENERATING MEANS SO THAT THE HEAT GENERATED WILL HAVE AN ESSENTIALLY LINEAR CHARACTERISTIC WITH RESPECT TO THE APPLIED ENERGIZING CURRENT.
