Publication number: 20130318961Abstract: There is provided a polymeric actuator including: a pair of facing portions located so as to face each other; and a folded portion through which one end portions of the pair of facing portions are coupled to each other, wherein the pair of facing portions and the folded portion are composed of an inner electrode layer, an electrolyte layer, and an outer electrode layer which are laminated in order from an inside. Therefore, the displacements are generated in the pair of facing portions, respectively, to be added to each other, and the displacement is generated in the folded portion as well due to the bending. As a result, the large displacement is generated as a whole. Thus, it is possible to increase the displacement amount after the simplification of the structure is realized.Type: ApplicationFiled: May 22, 2013Publication date: December 5, 2013Applicant: Sony CorporationInventors: KAZUHIRO HONGO, KOJI FUKUMOTO, TAKASHI KINOSHITA

Patent number: 8037760Abstract: An inertial sensor includes an oscillator that is supported by an elastic supporting member such that the oscillator is floating relative to a base and the oscillator is displaceable along a single axis, and a displacement detection unit detecting a displacement of the oscillator. The oscillation of the oscillator is a simple harmonic motion along a Z axis. An X axis, a Y axis, and the Z axis, serving as reference axes of an oscillation coordinate system for the oscillator, are shifted to provide x, y, and z axes, serving as new reference axes. Position coordinates of the oscillator of the x, y, and z axes are determined in at least two points during one period of the oscillator. A difference vector (?x, ?y, ?z) is calculated on the basis of the determined position coordinates. An angular velocity or an acceleration is obtained using the difference vector.Type: GrantFiled: March 31, 2008Date of Patent: October 18, 2011Assignee: Sony CorporationInventor: Koji Fukumoto

Patent number: 8007036Abstract: According to an inner panel for vehicles of the present invention, a bead forming surface is so provided as to extend continuously with an upper edge part of a wall rising from a bottom surface of the inner panel. Upper beads and lower beads are formed on the bead forming surface. The upper and lower beads extend in a longitudinal direction of a vehicle and are arranged alternately in a width direction of the vehicle. The bead forming surface is positioned above a middle position between an upper surface of the upper bead and a lower surface of the lower bead. Further, the bead forming surface is positioned lower than the upper surface of the upper bead by 3 mm or more. With this structure, a sufficient first acceleration wave can be secured by expanding a stress propagation range in a direction perpendicular to the length of the beads with respect to the first acceleration wave and, also, by reducing a local deformation to be caused by a deformation load from the above of the vehicle during a head impact.Type: GrantFiled: October 6, 2008Date of Patent: August 30, 2011Assignee: Kobe Steel, Ltd.Inventors: Koji Fukumoto, Masatoshi Yoshida

Patent number: 7699386Abstract: The invention provides a roof reinforcement member including an extruded aluminum alloy part which is upwardly convex and extends in a vehicle lateral direction. The extruded aluminum alloy part includes a pair of upper and lower flanges approximately parallel-facing each other as seen in a cross-section thereof and a pair of webs formed to stand along the vehicle height direction. The pair of flanges and the pair of webs form a closed sectional part. The pair of flanges each have a projecting flange portion. In the cross-section, the lower flange is thicker than the upper flange and/or the lower flange is wider than the upper flange, and the neutral axis of upward/downward bending is positioned lower than the middle of the height of the cross-section. This arrangement can reduce the stress generated on the lower side of the cross-section when the extruded aluminum alloy part is bent, so that the extruded aluminum alloy part can be effectively made stronger against deformation.Type: GrantFiled: December 18, 2008Date of Patent: April 20, 2010Assignee: Kobe Steel, Ltd.Inventor: Koji Fukumoto
