Patent number: 11199207Abstract: The motion guide device clamper mechanism includes a clamper main body connected to the movable member, an inner face having a tapered shape so that the distance between the facing faces is narrower toward the end of one face of the track member, and one rolling member disposed between the facing faces of the one face of the track member and the inner face. The rolling member receives a pressing force toward a position where the distance between the facing faces of one face of the track member and the inner face of the clamper main body is narrow, so that a frictional force based on the taper shape acts on the rolling member, and the restraint of the clamper main body with respect to the track member is performed. Further, a frictional force based upon the taper shape is released and the non-restraint of the clamper is performed.Type: GrantFiled: March 6, 2018Date of Patent: December 14, 2021Assignees: THK CO., LTD., NABEYA BI-TECH KABUSHIKI KAISHAInventors: Hiroaki Mochizuki, Hiroomi Kuribayashi, Keisuke Hagiwara, Masahiro Aoyama

Patent number: 10570954Abstract: This rotation ring includes an inner ring with a first rolling element travel groove, an outer ring with a second rolling element travel groove that faces the first rolling element travel groove, and a plurality of rolling elements interposed between the first rolling element travel groove and the second rolling element travel groove. The plurality of rolling elements include a plurality of hard rolling elements disposed at intervals in the circumferential direction, and a plurality of soft rolling elements, at least three or more of which are disposed between the hard rolling elements adjacent to each other in the circumferential direction and which are lower in rigidity than the hard rolling elements.Type: GrantFiled: October 14, 2016Date of Patent: February 25, 2020Assignee: THK CO., LTD.Inventors: Hiroaki Mochizuki, Keisuke Hagiwara

Patent number: 10351023Abstract: A seat moving/securing device 10 includes a long reference member 11 extending in a longitudinal direction of a seat installation surface and securely installed, a leg part attachment member 50a having securely installed therein a leg part of a seat, a linear guide 20 attached between the long reference member 11 and the leg part attachment member 50a and enabling the leg part attachment member 50a to move horizontally along a longitudinal direction of the long reference member 11, and a locking mechanism 60 securely installed on the leg part attachment member 50a. A coil spring 68 serving as an elastic body exhibiting a pressing force is installed between the leg part attachment member 50a and the linear guide 20. Due to having this type of configuration, the seat moving/securing device 10 can move and secure a seat 200 easily and quickly.Type: GrantFiled: April 25, 2016Date of Patent: July 16, 2019Assignee: THK CO., LTD.Inventors: Kaoru Hoshide, Hiroaki Mochizuki, Eiji Hosaka, Hiroomi Kuribayashi, Akito Kaneko, Keisuke Hagiwara

Patent number: 9751632Abstract: Provided is a moving unit capable of easily mounting and dismounting a movable body to and from track rails. The moving unit includes the pair of track rails, which are laid on a fixed portion at an interval therebetween, and respectively have guiding surfaces on surfaces opposed to each other, a plurality of moving blocks, which are accommodated and arranged in an accommodating space sandwiched between the pair of track rails, and are configured to travel on the guiding surfaces of the respective track rails, and the movable body, which is arranged so as to be opposed to the fixed portion across the accommodating space, and is retained by the moving blocks. The movable body includes a mounting and dismounting mechanism, which is configured to change the interval between the moving block to be assembled to one of the track rails and the moving block to be assembled to another one of the track rails to cancel a contact state between the moving blocks and the respective track rails.Type: GrantFiled: August 22, 2014Date of Patent: September 5, 2017Assignee: THK CO., LTD.Inventors: Hiroaki Mochizuki, Hiroomi Kuribayashi, Akito Kaneko, Keisuke Hagiwara, Yuji Sudo

Patent number: 8151779Abstract: Liquid ammonia is fed from an ammonia storage tank to a vaporizer where it is vaporized. Gaseous ammonia vaporized inside the vaporizer is on the one hand injected from an ammonia injector and on the other hand reformed by a reformer, then injected from a reformed gas injector. The amount of liquid ammonia fed into the vaporizer is made to become equal to the amount of ammonia fed into the combustion chamber in the form of gaseous fuel by control of the amount of feed of the liquid ammonia to the vaporizer.Type: GrantFiled: March 25, 2010Date of Patent: April 10, 2012Assignee: Toyota Jidosha Kabushiki KaishaInventors: Keisuke Hagiwara, Susumu Kojima
