Patent number: 10981619Abstract: In a rocking vehicle, a front wheel suspension device suspends a front wheel in an upwardly displaceable manner due to a reaction force from a road surface. The rocking vehicle includes a cushion support arm, on a body frame side, including a cushion support portion of the front wheel suspension device, and a rigidity adjustment device which is extended between plural portions of the cushion support arm. The rigidity adjustment device applies a pre-tension to the cushion support arm, and the pre-tension generates a pre-force component in the cushion support portion in the same direction as the upward moving direction of the front wheel due to a reaction force of the front wheel from the road surface.Type: GrantFiled: May 16, 2018Date of Patent: April 20, 2021Assignee: HONDA MOTOR CO., LTD.Inventors: Katsumasa Mukai, Satoru Kubo, Hiroki Yoshino, Hirohisa Takahashi, Kazuki Yamagishi, Ryuji Sasaki, Kiyotaka Sakai

Patent number: 10483834Abstract: A ball spline shaft integral with a foremost and rearmost nozzle fits into a movable table for an actuator to make sure of high accuracy and high tact operation. A movable table is constituted with a movable table in which a ball spline shaft to provide a ball spline is inserted into a table body. The ball spline shaft having a through-hole has a foremost nozzle at the lower portion thereof and a rearmost nozzle at the top thereof. An outer shell is fastened to the opposite ends of the bed and the ball spline shaft is supported by a pair of the outer shells for reciprocating movement.Type: GrantFiled: January 28, 2016Date of Patent: November 19, 2019Assignee: NIPPON THOMPSON CO., LTD.Inventor: Kazuki Yamagishi

Patent number: 9502953Abstract: A covering is easily mounted and/or demounted to envelop an overall sliding device with onboard moving-magnet linear motor. The covering helps improved propulsion, high velocity and response of a table even with small in dimension, compact in construction. End blocks are installed in opposite ends of a bed and a linear motor is placed between the bed and the table. The end blocks are made in solid bodies which are tightened to the bed together with a coil board. The end blocks have butting surfaces which can come into abutment against the ends of the table to protect the table from getting out of the bed. The end blocks have locking recesses which mate with locking jaws on the covering to fasten the covering to the end blocks.Type: GrantFiled: May 28, 2013Date of Patent: November 22, 2016Assignee: NIPPON THOMPSON, CO., LTD.Inventors: Eiji Ida, Ken Nomura, Kazuki Yamagishi

Patent number: 7878082Abstract: A sliding device is provided in which a ball-nut screw system is disposed in a relation lying out of a guide rail and extending by the side of and in parallel juxtaposition with the guide rail, thereby making it possible to reduce the sliding device in the overall height. The ball-nut lead screw system may be easily mounted and/or demounted from the sliding device and easily made varied depending on design considerations. The sliding device includes the lead screw carried for rotation by bracket bearings in a way lying out of a guide rail in a way extending by the side of and in parallel juxtaposition with the guide rail, and a ball nut mounted to a slide table. The lead screw is actuated by a motor carried in a bracket bearing.Type: GrantFiled: April 6, 2005Date of Patent: February 1, 2011Assignee: Nippon Thompson Co., Ltd.Inventor: Kazuki Yamagishi
