Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
169 words
THE METHOD OF MANUFACTURING A CERAMIC CAPACITOR INCLUDING THE STEPS OF: PROVIDING A SUPPORT MEMBER OF AN ECCENTRICALLY CONDUCTIVE ALLOY CONTAINING NICKEL AND BEING STABLE OVER A FIRST RANGE OF TEMPERATURES UP TO A PREDETERMINED TEMPERATURE, DEPOSITING A METAL FROM A GROUP CONSISTING OF GOLD, PLATINUM AND PALLADIUM ON ONE SURFACE OF SAID SUPPORT MEMBER, HEATING THE SUPPORT MEMBER AND NOBLE METAL TO A SECOND TEMPERATURE WHICH IS IN SAID RANGE AND LESS THAN SAID PREDETERMINED TEMPERATURE TO FUSE THE NOBLE METAL ONTO THE SAID SURFACE OF THE SUPPORT AND FORM AN ELECTRICALLY CONDUCTIVE FILM THAT IS IMPERVIOUS TO NICKEL AND IS ELECTRICALLY CONDUCTIVE, DEPOSITING A PULVERIZED CERAMIC INCLUDING BARIUM TITANATE ONTO THE FILM OF NOBLE METAL, FIRING THE CERAMIC LAYER TO A TEMPERATURE LESS THAN THE SECOND TEMPERATURE TO VITRIFY THE CERAMIC INTO A DIELECTRIC LAYER, DEPOSITING AN ELECTRICALLY CONDUCTIVE MATERIAL ON THE LAYER OF VITRIFIED CERAMIC, AND HEATING SAID ELECTRICALLY CONDUCTIVE MATERIAL TO A TEMPERATURE LESS THAN THE SECOND TEMPERATURE TO FORM A SECOND ELECTRICALLY CONDUCTIVE FILM.
Claim 2
Independent Claim

Claim 3
Dependent Claim
157 words
A CERAMIC CAPACITOR INCLUDING THE COMBINATION OF: A SUPPORT MEMBER FORMING THE MAIN STRUCTURAL SUPPORT OF THE CAPACITOR, SAID SUPPORT MEMBER INCLUDING AN ELECTRICALLY CONDUCTIVE MATERIAL WHICH IS EFFECTIVE TO RETAIN ITS STRUCTURAL STRENGTH THROUGH AN EXTENDED RANGE OF TEMPERATURES TO A PREDETERMINED ELEVATED TEMPERATURE AND WHICH HAS PROPERTIES OF EMITTING CONTAMINANTS ESPECIALLY AT ELEVATED TEMPERATURES IN THE EXTENDED RANGE, A FILM OF AN ELECTRICALLY CONDUCTIVE METAL FROM A GROUP CONSISTING OF GOLD, PLATINUM AND PALLADIUM, SAID FILM BEING BONDED TO THE SURFACE OF SAID SUPPORT MEMBER TO PREVENT THE TRANSFER OF CONTAMINANTS FROM THE SUPPORT MEMBER THROUGH THE FILM, SAID FILM FORMING ONE PLATE OF THE CAPACITOR, A VITRIFIED LAYER OF CERAMIC BONDED TO THE FILM OF NOBLE METAL AND HAVING A PREDETERMINED DIELECTRIC CONSTANT, AND A METALLIC FILM DISPOSED ON THE CERAMIC FILM AND SEPARATED FROM THE FIRST CONDUCTIVE FILM BY THE THICKNESS OF SAID CERAMIC FILM TO FORM THE SECOND PLATE OF THE CAPACITOR.
Claim 4
Dependent Claim
