Publication number: 20240136896Abstract: A magnet arrangement method in which magnetized magnets arranged in a Halbach array can be arranged at preset positions with a high accuracy is provided. The method includes an arrangement process of arranging a plurality of magnetized magnets in an arrangement jig made of a magnetic body, in which, in the arrangement process, a size of an area that the arrangement jig contacts a preset magnetized magnet is made different from a size of an area that the arrangement jig contacts another magnetized magnet.Type: ApplicationFiled: February 2, 2022Publication date: April 25, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Yushi TAKEUCHI

Patent number: 8626399Abstract: An inverted vehicle travels while maintaining an inverted state. The inverted vehicle includes specifying means for specifying a position at a predetermined distance from a step portion which a rider gets on or off, when the rider gets on or off the vehicle. The specifying means may project a predetermined shape onto the position at the predetermined distance from the step portion, or may cause a vehicle member to move to the position at the predetermined distance from the step portion. The inverted vehicle may further include position detecting means for detecting a position of a foot of the rider, and contact determining means for determining whether the foot is to contact the vehicle, based on the position of the foot detected by the position detecting means.Type: GrantFiled: August 30, 2010Date of Patent: January 7, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventors: Yushi Takeuchi, Yusuke Enomoto

Patent number: 8447506Abstract: A traveling device 10 includes ground touching detection means to detect a ground touching state in which a ground touching member touches a road surface, and control means to perform inversion control by controlling the driving of a wheel. When a ground touching state of the ground touching member is detected by the ground touching detection means, the control means suspends the inversion control. Further, when the start of braking is detected by the braking detection means and a ground touching state of the ground touching member is detected by the ground touching means, the control means may suspend the inversion control.Type: GrantFiled: March 31, 2010Date of Patent: May 21, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventors: Toshio Fuwa, Yushi Takeuchi, Takashi Izuo

Patent number: 6397121Abstract: There are provided a process and an apparatus for detecting loop stitches of a tubular knitted fabric and an apparatus for linking the tubular knitted fabric, which can automatically detect each of loop stitches formed in the tubular knitted fabric. According to the process for detecting the loop stitches, the tubular knitted fabric is extended by inserting a penetration element through the interior of the fabric having the loop stitches, and a multi-gradation image including an image of the loop stitches of the tubular knitted fabric extended by the penetration element is picked up. The locations of the loop stitches are detected by processing the multi-gradation image. The apparatus for detecting the loop stitches includes the penetration element, an image pickup device for picking up the multi-gradation image, and a loop stitch detecting section for detecting the locations of the loop stitches by processing the multi-gradation image.Type: GrantFiled: January 13, 1999Date of Patent: May 28, 2002Assignee: Dan Co., Ltd.Inventors: Sadao Kawamura, Akira Ishii, Takahiro Wada, Takuya Fukitsuke, Yushi Takeuchi
