Patent number: 9428199Abstract: A railcar bogie plate spring of the present invention includes: an upper surface member constituted by fiber reinforced plastic in which reinforced fibers are stacked so as to extend in a longitudinal direction; a lower surface member constituted by fiber reinforced plastic in which reinforced fibers are stacked so as to extend in the longitudinal direction; and a core member arranged between the upper surface member and the lower surface member. The core member is constituted by fiber reinforced plastic in which: reinforced fibers are stacked in a width direction perpendicular to a stack direction of the upper surface member and the lower surface member; and in a side view of the core member, the reinforced fibers are inclined relative to a bending neutral axis so as to intersect with one another.Type: GrantFiled: September 13, 2012Date of Patent: August 30, 2016Assignees: GH CRAFT LTD., KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Gaku Kimura, Mitsuhiro Furuya, Shunichi Nakao, Takehiro Nishimura

Patent number: 8413598Abstract: A sailing ship includes a sailing unit, which comprises a hard sail assembly comprising a plurality of hard sail sections of wing-shaped hollow cross section vertically stacked so each, except the lowermost, fits on the one immediately below; a mast assembly comprising a plurality of mast sections of hollow cross section vertically stacked so each, except the lowermost, fits in the one immediately below; connecting members for connecting upper ends of the hard sail sections to upper ends of the mast sections located at the same level; first means for moving each mast section, except the lowermost, toward and away from the one immediately below; and second means for rotating the mast assembly around its longitudinal axis. Overlapping lengths between vertically adjacent mast sections are variably controlled so as to variably control overlapping lengths between vertically adjacent hard sail sections. Thus, the hard sail assembly vertically expands and contracts.Type: GrantFiled: March 18, 2011Date of Patent: April 9, 2013Assignees: Ouchi Ocean Consultant, Inc., GH Craft LtdInventors: Kazuyuki Ouchi, Kiyoshi Uzawa, Gaku Kimura

Patent number: 8406624Abstract: An optical hub node apparatus can be configured to include N+1 or more route units (10) by connecting N or less route units (10) selected from among the N+1 or more route units (10) to a route unit (10) including N (N:integer of 2 or more) ports to which other route units (10) are detachably connected. As a result, as compared with a case where N+1 route units (10) are completely interconnected in a meshed manner, the number of the route units (10) can be increased. Thus, the number (degree) of optical transmission apparatuses connectable to the optical hub node apparatus can be increased.Type: GrantFiled: August 24, 2009Date of Patent: March 26, 2013Assignee: Fujitsu LimitedInventors: Gaku Kimura, Takayuki Shimizu, Taro Asao

Patent number: 8117978Abstract: A sailing ship comprises a hard sail assembly. The hard sail assembly comprises a plurality of hard sails of wing-shaped hollow cross section. The hard sails are vertically stacked so that each except the lowermost is received in the one immediately below. The sailing ship further comprises an apparatus for driving the hard sails to move each except the lowermost toward and away from the one immediately below, a post extending vertically to support the lowermost hard sail, and a second apparatus for rotating the post around its longitudinal axis. Overlapping lengths between vertically adjacent hard sails are variably controlled to make the hard sail assembly expand and contract vertically.Type: GrantFiled: February 5, 2010Date of Patent: February 21, 2012Assignees: Ouchi Ocean Consultant, Inc., GH Craft Ltd.Inventors: Kazuyuki Ouchi, Gaku Kimura

Patent number: 7548693Abstract: A relay transmission apparatus in which the effectiveness of a protecting function is improved by suppressing variation of an OSNR value of a signal regardless of the distance that the signal is transmitted. The relay transmission apparatus is comprised of a first regenerative relay unit, a second regenerative relay unit, and a protection process unit for extracting a signal component from each of the first and second regenerative relay units and selectively outputting either of the extracted signal components as a drop signal.Type: GrantFiled: July 28, 2004Date of Patent: June 16, 2009Assignee: Fujitsu LimitedInventors: Gaku Kimura, Koji Takeguchi

Patent number: 7219147Abstract: An object of the present invention is to propose a method of effecting a protection control for use in a communication network which makes it possible to avoid conflict between a protection switch of a SONET apparatus and a protection switch of an RPR apparatus. To this end, when ring switching of the BLSR is validated, the protection function of the RPR apparatus is invalidated while when the protection function of the RPR apparatus is validated, the ring switching of the BLSR is invalidated. The apparatus of the present invention can be applied to a network in which a ring network formed of a BLSR is connected with an RPR apparatus.Type: GrantFiled: November 19, 2002Date of Patent: May 15, 2007Assignee: Fujitsu LimitedInventors: Gaku Kimura, Yuzuru Ishioka
