Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
27 words
AN ELECTRICAL CIRCUIT ELEMENT HAVING A BODY OF HIGH DIELECTRIC CONSTANT MATERIAL HAVING THROUGHOUT PROPERTIES OF A SEMICONDUCTOR AND A CONDUCTING ELECTRODE SECURED TO A SURFACE THEREOF.
Claim 2
Dependent Claim
27 words
AN ELECTRICAL CIRCUIT ELEMENT HAVING A BODY OF HIGH DIELECTRIC CONSTANT MATERIAL HAVING THROUGHOUT PROPERTIES OF A SEMICONDUCTOR AND A CONDUCTING ELECTRODE SECURED TO A SURFACE THEREOF.
Claim 3
Independent Claim
56 words
THE METHOD OF MAKING AN ELECTRICAL CIRCUIT ELEMENT INCLUDING FORMING A BODY OF TITANATES OF BARIUM AND STRONTIUM WITH A MINOR ADDITIVE OF RARE EARTH OXIDE, FIRING SAID BODY TO MATURITY IN A REDUCING ATMOSPHERE TO MAKE SAID BODY THROUGHOUT A UNIFORM SEMICONDUCTOR HAVING A HIGH DIELECTRIC CONSTANT, AND FIRING A METAL ELECTRODE ONTO SAID BODY.
Claim 4
Independent Claim
56 words
THE METHOD OF MAKING AN ELECTRICAL CIRCUIT ELEMENT INCLUDING FORMING A BODY OF TITANATES OF BARIUM AND STRONTIUM WITH A MINOR ADDITIVE OF RARE EARTH OXIDE, FIRING SAID BODY TO MATURITY IN A REDUCING ATMOSPHERE TO MAKE SAID BODY THROUGHOUT A UNIFORM SEMICONDUCTOR HAVING A HIGH DIELECTRIC CONSTANT, AND FIRING A METAL ELECTRODE ONTO SAID BODY.
Claim 5
Dependent Claim
66 words
AN ELECTRICAL CIRCUIT ELEMENT HAVING A BODY CONSISTING ESSENTIALLY OF SINTERED METALLIC OXIDES IN REDUCED STATE HAVING A HIGH DIELECTRIC CONSTANT AND PROVIDING THROUGHOUT AN N-TYPE SEMICONDUCTOR IN WHICH THE NUMBER OF EXCESS CARRIERS ARE LIMITED, A CONDUCTING ELECTRODE BONDED TO A SURFACE OF SAID BODY, AND A NON-OHMIC BARRIER LAVER BETWEEN SAID CONDUCTING ELECTRODE AND SAID BODY HAVING THE SAME CHEMICAL PROPERTIES AS SAID SEMICONDUCTOR.
Claim 6
Dependent Claim
66 words
AN ELECTRICAL CIRCUIT ELEMENT HAVING A BODY CONSISTING ESSENTIALLY OF SINTERED METALLIC OXIDES IN REDUCED STATE HAVING A HIGH DIELECTRIC CONSTANT AND PROVIDING THROUGHOUT AN N-TYPE SEMICONDUCTOR IN WHICH THE NUMBER OF EXCESS CARRIERS ARE LIMITED, A CONDUCTING ELECTRODE BONDED TO A SURFACE OF SAID BODY, AND A NON-OHMIC BARRIER LAVER BETWEEN SAID CONDUCTING ELECTRODE AND SAID BODY HAVING THE SAME CHEMICAL PROPERTIES AS SAID SEMICONDUCTOR.
