Method of producing coated ceramic capacitor

Claim 1

THE METHOD OF PRODUCING A CERAMIC CAPACITOR COMPRISING APPLYING A HOT-MELT TYPE SILVER COMPOSITION BY THE SQUEEGEE METHOD OF ONE SIDE OF A CERAMIC DIELECTRIC CHIP WHILE MAINTAINING SAID COMPOSITION AT A TEMPERATURE OF 120* TO 230* F. AND WHILE SAID CHIP IS AT A TEMPERATURE AT LEAST 15* F. BELOW TH MELTING TEMPERATURE OF SAID COMPOSITION AND, WITHOUT INTERMEDIATE DRYING, APPLYING AN AIR-DRY TYPE SILVER COMPOSITION TO THE REVERSE SIDE OF SAID CHIP THEN FIRING THE RESULTING COATED CHIP, SAID HOT-MELT COMPOSITION BEING NON-VOLATILE AND SOLID AT NORMAL TEMPERATURE AND COMPRISING A DISPERSION OF FINELY DIVIDED SILVER IN A VEHICLE WHICH CONTAINS, ON A WEIGHT BASIS: (A) 30 TO 80% OF A MATERIAL WHICH MELTS WITHIN THE RANGE 120 TO 230* F. AND IS SELECTED FROM THE GROUP CONSISTING OF WAXES, MIXTURES OF WAXES AND MIXTURE OF A WAX WITH A MATERIAL FROM THE GROUP CONSISTING OF PALMITIC AND STEARIC ACIDS; (B) 14 TO 68% OF A MATERIAL FROM THE GROUP CONSISTING OF ROSIN AND ABIETIC ACID, ROSIN ESTERS AND ESTERS OF ABIETIC ACID, POLYMERIZED ROSIN AND POLYMERIZED ABIETIC ACID, HYDROGENATED ROSIN AND HYDROGENATED ABIETIC ACID, AND METAL SALTS OF ROSIN AND OF ABIETIC ACID; (C) 1 TO 10% OF ETHYL CELLULOSE; AND (D) 0.5 TO 10% OF AN ORGANIC PHOSPHATE MATERIAL FROM THE GROUP CONSISTING OF LECITHIN AND PHOSPHORATED TALL OIL, SAID AIR-DRY COMPOSITION COMPRISING A DISPERSION OF FINELY DIVIDED SILVER IN A VEHICLE WHICH INCLUDES A VOLATILE SOLVENT AND HAS THE PROPERTY OF SOLIDIFYING UPON REMOVAL OF SAID VOLATILE SOLVENT THEREFROM BY DRYING.

Claim 2

THE METHOD OF PRODUCING A CERAMIC CAPACITOR COMPRISING APPLYING A HOT-MELT TYPE SILVER COMPOSITION BY THE SQUEEGEE METHOD OF ONE SIDE OF A CERAMIC DIELECTRIC CHIP WHILE MAINTAINING SAID COMPOSITION AT A TEMPERATURE OF 120* TO 230* F. AND WHILE SAID CHIP IS AT A TEMPERATURE AT LEAST 15* F. BELOW TH MELTING TEMPERATURE OF SAID COMPOSITION AND, WITHOUT INTERMEDIATE DRYING, APPLYING AN AIR-DRY TYPE SILVER COMPOSITION TO THE REVERSE SIDE OF SAID CHIP THEN FIRING THE RESULTING COATED CHIP, SAID HOT-MELT COMPOSITION BEING NON-VOLATILE AND SOLID AT NORMAL TEMPERATURE AND COMPRISING A DISPERSION OF FINELY DIVIDED SILVER IN A VEHICLE WHICH CONTAINS, ON A WEIGHT BASIS: (A) 30 TO 80% OF A MATERIAL WHICH MELTS WITHIN THE RANGE 120 TO 230* F. AND IS SELECTED FROM THE GROUP CONSISTING OF WAXES, MIXTURES OF WAXES AND MIXTURE OF A WAX WITH A MATERIAL FROM THE GROUP CONSISTING OF PALMITIC AND STEARIC ACIDS; (B) 14 TO 68% OF A MATERIAL FROM THE GROUP CONSISTING OF ROSIN AND ABIETIC ACID, ROSIN ESTERS AND ESTERS OF ABIETIC ACID, POLYMERIZED ROSIN AND POLYMERIZED ABIETIC ACID, HYDROGENATED ROSIN AND HYDROGENATED ABIETIC ACID, AND METAL SALTS OF ROSIN AND OF ABIETIC ACID; (C) 1 TO 10% OF ETHYL CELLULOSE; AND (D) 0.5 TO 10% OF AN ORGANIC PHOSPHATE MATERIAL FROM THE GROUP CONSISTING OF LECITHIN AND PHOSPHORATED TALL OIL, SAID AIR-DRY COMPOSITION COMPRISING A DISPERSION OF FINELY DIVIDED SILVER IN A VEHICLE WHICH INCLUDES A VOLATILE SOLVENT AND HAS THE PROPERTY OF SOLIDIFYING UPON REMOVAL OF SAID VOLATILE SOLVENT THEREFROM BY DRYING.
