Publication number: 20230406546Abstract: Provided is a space vehicle that includes: a main body; a movable portion configured to reciprocate in an axial direction with respect to the main body; and a magnetic force generation unit attached to a distal end of the movable portion, and attracts, by a magnetic force, a platelike body attached to an object in outer space. The magnetic force generation unit includes: a magnet support member attached to a distal end of the movable portion via a buffer elastic body; and a plurality of permanent magnets laid on a surface of the magnet support member to form an attraction region. When a drive unit moves the movable portion away from the main body, the attraction region protrudes from the main body while maintaining a fixed orientation crossing the axial direction, and is changeable in position and/or orientation by the buffer elastic body when an external force is applied.Type: ApplicationFiled: October 6, 2021Publication date: December 21, 2023Inventors: Takashi Iwai, Kenji Sagara, Sho Fujita

Patent number: 9637172Abstract: Upon a rear-end collision of a vehicle, an arm section(s) of a cross member of a rear suspension member on the rear side of the vehicle, which is(are) positioned in a low-strength region in a vehicle-body strength distribution, undergoes crush deformation together with a corresponding rear side member(s). Deformation of the part of the rear suspension member other than the arm sections, which is positioned in a high-strength region in the vehicle-body strength distribution, is suppressed, so that a high voltage component mounted in the high-strength region is protected.Type: GrantFiled: October 20, 2014Date of Patent: May 2, 2017Assignee: NISSAN MOTOR CO., LTD.Inventors: Kenji Sagara, Takeo Ehara

Patent number: 8585065Abstract: In a suspension structure, a suspension link has a hollow structure in which a pair of frame brackets are joined together, while opposing each other. Also provided is a stiffening bracket integrally connected to both the frame brackets for holding and sandwiching the frame brackets together. The stiffening bracket is configured to hold and sandwich both an end face of a first one of the frame brackets facing apart from the mating face with the second frame bracket and an end face of the second frame bracket facing apart from the mating face with the first frame bracket together. One end of a stabilizer, a height sensor, or the like is connected to the stiffening bracket.Type: GrantFiled: March 6, 2012Date of Patent: November 19, 2013Assignee: Nissan Motor Co., Ltd.Inventors: Reo Koide, Kenji Sagara, Jiro Inatomi, Kazuhiro Kiriyama, Toshiyuki Kondou

Patent number: 8342542Abstract: A suspension device includes a wheel supporting member configured to rotatably support a wheel. Two links respectively link the wheel supporting member and a vehicle-body side member and are disposed substantially in parallel in a vehicle width direction. At least one projecting portion extends from at least one of the two links towards the other link, and an elastic linking portion links the projecting portion of one of the links to at least one of the other link and the projecting portion of the other link. A toe angle adjusting device is configured to input a force in a direction oriented backward in the vehicle forward-backward direction to the wheel supporting member to adjust a toe-in angle of the wheel.Type: GrantFiled: April 2, 2008Date of Patent: January 1, 2013Assignee: Nissan Motor Co., Ltd.Inventors: Kenji Sagara, Yusuke Kageyama, Yoshihiro Kawabe, Masahiko Nishida, Isao Watanabe, Masaya Kunitomo, Masaki Ohta
