Electric capacitor and method for producing the same

Claim 1

A MONOLITHIC CERAMIC CAPACITOR CONSISTING OF A CERAMIC CORE HAVING AN INNER ELECTRODE OF METAL SUFFICIENTLY REFRACTORY TO WITHSTAND THE FIRING TEMPERATURE OF THE CERAMIC, EXPOSING ONE END OF AND SUBSTANTIALLY COMPLETELY COVERING AND BONDED TO SUBSTANTIALLY THE ENTIRE REMAINING SURFACE AREA INCLUDING THE OTHER END OF THE CORE, A CERAMIC DIELECTRIC FILM SUBSTANTIALLY COVERING AND DIRECTLY BONDED TO SUBSTANTIALLY THE ENTIRE OUTER SURFACE OF SAID INNER ELECTRODE OTHER THAN THE PORTION THEREOF COVERING SAID OTHER END OF THE CORE AND AN OUTER ELECTRODE COVERING SAID CERAMIC DIELECTRIC FILM AND BONDED TO SUBSTANTIALLY THE ENTIRE AREA THEREOF, SAID CAPACITOR HAVING AN INSULATING COATING WITH TERMINALS ACCESSIBLE THERETHROUGH AND CONNECTED RESPECTIVELY TO SAID INNER AND OUTER ELECTRODES, SAID CERAMIC AND INNER ELECTRODES BEING SUBSTANTIALLY INERT WITH RESPECT TO EACH OTHER.

Claim 3

THE METHOD OF PREPARING A CERAMIC CAPACITOR WHICH COMPRISES APPLYING TO THE SURFACE OF A CORE OF GREEN CERAMIC, A SUSPENSION OF METAL OVER SUBSTANTIALLY THE ENTIRE SURFACE OF THE CORE OTHER THAN ONE END PORTION THEREOF, DRYING THE SUSPENSION, COATING THE METAL COATED CORE WITH A SLIP OF CERAMIC DIELECTRIC COMPOSITION CORRESPONDING TO THAT OF THE CORE, DRYING THE SLIP COATING, FIRING THE UNIT TO THE MATURING TEMPERATURE OF THE DIELECTRIC COATING, APPLYING A METAL ELECTRODE OVER THE COMMON END OF THE CORE AND SLIP AND OVER NEARLY THE ENTIRE LENGTH OF THEOUTER SURFACE OF THE SLIP, LEAVING EXPOSED THE END PORTION OF THE SLIP AT THE EXTREMITY OF THE CORE OPPOSED TO THAT BEYOND THE EXTREMITY OF THE INNER ELECTRODE, DRYING AND FIRING THE UNIT, AND EFFECTING TERMINAL CONNECTIONS RESPECTIVELY AT THE EXTREMITY OF THE OUTER ELECTRODE AND AT THE EXTREMITY OF THE INNER ELECTRODE AT OPPOSED ENDS OF THE CORE.

Claim 4

THE METHOD OF PREPARING A CERAMIC CAPACITOR WHICH COMPRISES APPLYING TO THE SURFACE OF A CORE OF GREEN CERAMIC, A SUSPENSION OF METAL OVER SUBSTANTIALLY THE ENTIRE SURFACE OF THE CORE OTHER THAN ONE END PORTION THEREOF, DRYING THE SUSPENSION, COATING THE METAL COATED CORE WITH A SLIP OF CERAMIC DIELECTRIC COMPOSITION CORRESPONDING TO THAT OF THE CORE, DRYING THE SLIP COATING, FIRING THE UNIT TO THE MATURING TEMPERATURE OF THE DIELECTRIC COATING, APPLYING A METAL ELECTRODE OVER THE COMMON END OF THE CORE AND SLIP AND OVER NEARLY THE ENTIRE LENGTH OF THEOUTER SURFACE OF THE SLIP, LEAVING EXPOSED THE END PORTION OF THE SLIP AT THE EXTREMITY OF THE CORE OPPOSED TO THAT BEYOND THE EXTREMITY OF THE INNER ELECTRODE, DRYING AND FIRING THE UNIT, AND EFFECTING TERMINAL CONNECTIONS RESPECTIVELY AT THE EXTREMITY OF THE OUTER ELECTRODE AND AT THE EXTREMITY OF THE INNER ELECTRODE AT OPPOSED ENDS OF THE CORE.
