  • Patent number: 7915787
    Abstract: A cylindrical piezoelectric element is arranged to share an axis with a cylindrical vibrator having different diameters at central and end portions to fix the vibrator forming a gap at the central portion. Vibration voltages are applied across first electrodes on the piezoelectric element and the vibrator, namely, a second electrode, to vibrate the vibrator and bring a wave front of a traveling wave into contact with a tubular member, i.e., a supporting member fitted to the vibrator. Friction at a contact portion of the vibrator moves a mover including the vibrator and the piezoelectric element in an axial direction of the tubular member. By amplifying the vibration amplitude using the vibrator provided separately from the piezoelectric element, a small actuator capable of performing high-speed driving is realized.

  • Publication number: 20070102290
    Abstract: This invention provides a novel material development apparatus capable of automatically and efficiently forming uniform novel materials with reduced impurities and different compositions individually on respective cells. The novel material development apparatus includes: a plurality of arc plasma guns; a magnetic circuit deflecting/focusing plasma of the arc plasma guns; a controller thereof; and a plurality of deposition cells. For film deposition, plasma containing ions of constituent elements and generated in a pulsed manner by the arc plasma guns are focused to the deposition cell by the magnetic circuit. We can switch the deposition cells by using the moving stage or by using the magnetic circuit changing a focus point, or we can change a focus point by using magnetic circuit so that collectively form uniform novel materials with reduced impurities and different compositions of alloys or compounds efficiently.

  • Patent number: 7026696
    Abstract: A thin film made of an amorphous material having a supercooled liquid phase region is formed on a substrate. Then, the thin film is heated to a temperature within the supercooled liquid phase region and is deformed by its weight, mechanical external force, electrostatic external force or the like, thereby to form a thin film-structure. Thereafter, the thin film-structure is cooled down to room temperature, which results in the prevention of the thin film's deformation.
