  • Patent number: 8390990
    Abstract: A solid electrolytic capacitor includes a capacitor element having an anode portion, a dielectric film and a cathode portion, an anode lead frame, a cathode lead frame, and a molded resin for covering at least a part of the anode and cathode lead frames and the capacitor element. In a cathode lead frame opposed portion opposed to the capacitor element with a conductive adhesive material being interposed is provided with a through hole having a narrowed portion smaller in diameter than other portions between a capacitor-element-side opening portion and a molded-resin-side opening portion, and the conductive adhesive material is formed in the through hole.

  • Patent number: 7808773
    Abstract: To provide electronic parts having a platy terminal secured through a conductive adhesive layer onto a device, which electronic parts are low in ESR and excel in the bonding strength between device and terminal. The conductive adhesive contains a flat conductive member and an organic solvent and is characterized in that through vaporization of the organic solvent in vacuum atmosphere, the flat conductive member has a region standing in the direction of thickness of the conductive adhesive layer. Further, the conductive adhesive is characterized by containing portion wherein the angle between the platy terminal and the flat plane of conductive member is ?45°.

  • Patent number: 5768072
    Abstract: A magnetic head comprises a first abutting segment formed with a winding groove having an open side, and a second abutting segment opposed to the open side of the groove and joined to the first segment. The first abutting segment comprises a first core segment having the groove, and gap spacers and second ferromagnetic thin films formed on the surface thereof opposed to the second segment and positioned above and below the groove. The first core segment comprises a core segment member made of a ferromagnetic material, formed with the groove and having a first ferromagnetic thin film which is formed on the surface thereof opposed to the second abutting segment and which is positioned toward the face of the head to be opposed to recording media. The second abutting segment has a face to be opposed to the recording medium and formed by a nonmagnetic material.
