Abstract
Abstract A ceramic laminated capacitor having an approximately cylindrical external configuration. Dielectric layers and inner electrode layers are laminated, and the inner electrode layers are connected to outer electrodes to unite them into one body. A pair of insulators having a vertical section of a segment are bonded to the opposing end surfaces of the dielectric layers such that the convex surfaces of the insulators face outward.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
102 words
A generally cylindrical, ceramic laminated capacitor adapted to be fed by automatic tube feeding means, comprising: ceramic dielectric layers and inner electrode layers laminated on each other; outer electrodes connected to said inner electrode layers to unite said ceramic dielectric layers, said inner electrode layters and said outer electrodes into one body; and a pair of insulators, having an arcuate outer surface of convex configuration and a flat inner surface, which are integrally bonded to opposing end surfaces of said dielectric layers such that the convex surfaces of said insulators face outward to form with said dielectric layers said generally cylindrical shape.
Claim 2
Dependent Claim
102 words
A generally cylindrical, ceramic laminated capacitor adapted to be fed by automatic tube feeding means, comprising: ceramic dielectric layers and inner electrode layers laminated on each other; outer electrodes connected to said inner electrode layers to unite said ceramic dielectric layers, said inner electrode layters and said outer electrodes into one body; and a pair of insulators, having an arcuate outer surface of convex configuration and a flat inner surface, which are integrally bonded to opposing end surfaces of said dielectric layers such that the convex surfaces of said insulators face outward to form with said dielectric layers said generally cylindrical shape.
Claim 3
Dependent Claim
40 words
A ceramic laminated capacitor according to claim 1, wherein said insulators are formed by press bonding green sheets to the upper and lower ends, respectively, of said dielectric layer in the direction of lamination when said dielectric layers are laminated.
Claim 4
Dependent Claim
21 words
A ceramic laminated capacitor according to claim 1, wherein said insulators are integrally bonded to said dielectric layers by an adhesive.
