  • Patent number: 11170941
    Abstract: A solid electrolytic capacitor that includes a capacitor element laminate, a first external electrode, and a second external electrode. The capacitor element laminate includes capacitor elements, cathode lead-out layers, and a sealing body. At least one of the capacitor elements includes an anode foil, dielectric layers, and cathode layers. The first external electrode is connected to the anode foil exposed at the first end surface of the capacitor element laminate. The second external electrode is connected to the cathode lead-out layers exposed at the second end surface of the capacitor element laminate. The sealing body includes a first resin molded body and a second resin molded body. The first resin molded body and the second resin molded body are made of the same insulating material.

  • Patent number: 10991515
    Abstract: A solid electrolytic capacitor that includes a plurality of laminated units each including a valve action metal substrate including a porous layer on a surface thereof, a dielectric layer on a surface of the porous layer, and a solid electrolyte layer on the dielectric layer. A metal foil is between the laminated units. The units and the conductor layers are sealed with a coating resin. The valve action metal substrate has an anode section-side end surface directly connected to an anode outer electrode on the surface of the coating resin, and the metal foil is directly connected to a cathode outer electrode on the surface of the coating resin.

  • Patent number: 5205745
    Abstract: The present invention relates to an artificial ceramic dental root, wherein the outer circumference portion of the main body of the artificial dental root which has been implanted in the jaw bone is integrally formed of ceramic material; the diameter of a dental neck-corresponding portion of the artificial dental root extending from a part inserted into the top of the jaw bone to at least a part of the dental neck is made larger than that of a base; and a tapered portion is provided between said base and the dental neck-corresponding portion, whereby stress concentration is relieved and the artificial dental root is obtained which is highly resistant to outer forces, especially a force in an oblique direction. Even when a ceramic coated layer is layered over a metallic core to form a layer structure, the ceramic layer is prevented from coming off.
