    摘要： A piezoelectric driving device of the present invention prevents a short circuit from occurring between electrode metallic films even if bonding-wire is performed. The piezoelectric driving device is a piezoelectric driving device in which a piezoelectric thin plate is joined to one side of a substrate, and a terminal electrode for applying a signal for expanding or contracting the piezoelectric thin plate is further formed on the plane. The terminal electrode is formed on one side of the substrate via a piezoelectric-member pedestal separated from the piezoelectric thin plate.

    摘要： A fastening device includes a cylindrical shell with an opening extending over the entire length of the cylindrical shell, a gripping member formed on the periphery of the cylindrical shell by extending outward and a pair of hooks linked with the tip end of the cylindrical shell via hinges. A fastening method using the foregoing fastening device includes the steps of passing the pair of hooks through a hole for fastening of a packing box formed of an upper box and a lower box, having the pair of hooks opened outward to bring the holding members thereof into contact with the back side surface of the packing box and at the same time having the pair of hooks engaged with each other firmly. At this time, the gripping member is in contact with the front side surface of the packing box. Accordingly, both surfaces located at each respective rim of the hole for fastening are sandwiched between the pair of hooks and the gripping member. Furthermore, the fastening device is structured to make the position of engagement between the pair of hooks changeable, thereby allowing the angle of each respective hook against the cylindrical shell to change and allowing consequently the sandwiching distance between the gripping member and the pair of hooks to change.

    摘要： Includes the steps of preparing a sheet-like current collector 4 having a plurality of bumps 4A on a surface thereof, the plurality of bumps having a height of 3 μm or greater and 10 μm or less; and forming an active material body having a stacked structure on each of the bumps 4A of the current collector 4. The step of forming the active material body includes a first layer vapor deposition step of causing a vaporized vapor deposition material to be incident on the surface of the current collector 4 in a direction inclined with respect to the normal H to the current collector 4 to form a first layer 101a of the active material body on each bump 4A, the first layer 101a being located closest to the current collector; and a second layer vapor deposition step of causing the vaporized vapor deposition material to be incident on the surface of the current collector 4 in a direction inclined, with respect to the normal H to the current collector 4, opposite to the incidence direction of the vapor deposition material in the first layer vapor deposition step to form a second layer 102a on at least a part of the first layer 101a. In the first layer vapor deposition step, vapor deposition is performed while moving the current collector 4 in a direction in which the incidence angle ω of the vapor deposition material with respect to the normal H to the current collector 4 is decreased.
