  • Patent number: 7510641
    Abstract: A continuous process of forming a highly smooth surface on a metallic tape by passing a metallic tape having an initial roughness through an acid bath contained within a polishing section of an electropolishing unit over a pre-selected period of time, and, passing a mean surface current density of at least 0.18 amperes per square centimeter through the metallic tape during the period of time the metallic tape is in the acid bath whereby the roughness of the metallic tape is reduced. Such a highly smooth metallic tape can serve as a base substrate in subsequent formation of a superconductive coated conductor.

  • Patent number: 7465516
    Abstract: A lid of a battery case is supported on a shaft fixed on a battery box. The lid comprises a cover portion and a support arm for attaching the cover portion to the shaft. A hook formed on the cover portion engages with a hook receiver provided on the battery box, so as to retain the lid in a closed position. The hook is disengaged by sliding the lid from the closed position along the axial direction of the shaft, and the lid is subsequently rotated about the shaft to an open position. During rotation of the lid, a stopper abuts a side surface of the support arm to prevent sliding movement of the lid. When the lid is being rotated to be closed, the abutting stopper prevents jamming of the hook on top of the hook receiver.
