Claim 1
Independent Claim
130 words
A METHOD FOR CONTROLLING AND MAINTAINING THE OUTPUT POWER AND ELECTRICAL CHARACTERISTICS OF AN ENCLOSED GROUP OF INTERNAL CONDUCTOR ELEMENTS OPERATING AT DIFFERENT TEMPERATURE GRADIENTS WITHIN AN ENCLOSED ELECTRONIC STRUCTURE AS DESCRIBED, CONSISTING OF THE STRPS OF POSITIONING THE INDEPENDENT RIMS OF A PLURALITY OF GRADIENT HEAT CONDUCTIONG FIN MEANS IN RELATIVELY SEPARATE CLOSE SPACED RELATIONSHIP TO EACH OTHER ABOUT THE ENCLOSURE FOR SAID ENCLOSED GROUP OF SAID INTERNAL ELEMENTS, THEREBY SEPARATELY AND INDEPENDENTLY EFFECTING THE ABSORPTION, CONDUCTION, AND RADIATION OF THE INTERNALLY CREATED HEAT OF EACH OF SAID INTERNAL CONDUCTOR ELEMENTS BY INDEPENDENTLY CONDUCTING THE ACCUMULATED HEAT AWAY FROM EACH OF THE SAID INTERNAL ELEMENTS, AND THEREBY REDUCING AND MAINTAINING THE INTERNAL HEAT PATTERN OF SAID ELEMENTS WHILE UNIFORMLY MAINTAINING THE ELECTRICAL CHARACTERISTICS AND POWER OUTPUT OF SAID ELEMENTS.
