Patent number: 10274963Abstract: A mowing vehicle provided with a traveling machine and a mowing device includes a first image-capturing device and a controlling unit configured to control the traveling machine to travel autonomously along a boundary line of grass before and after mowing formed by the mowing device. The controlling unit includes a boundary-detecting unit configured to detect the boundary line and a traveling-controlling unit configured to control traveling directions of the traveling machine. The boundary-detecting unit is configured to generate intensity distribution information regarding texture information in a predetermined direction by filtering with a Gabor filter on a captured image. The boundary-detecting unit is configured to carry out statistical processing on the intensity distribution information per inspection area divided in plural in a vertical direction so as to detect boundary points and to detect the boundary line from the boundary points per the inspection area.Type: GrantFiled: December 10, 2015Date of Patent: April 30, 2019Assignee: YANMAR CO., LTD.Inventors: Toshio Fukuda, Kosuke Sekiyama, Yasuhisa Hasegawa, Tomoya Fukukawa, Toshifumi Hiramatsu

Patent number: 8647744Abstract: To provide a composite that can find application to various uses in a wide spectrum of fields, for example, sealing members, such as a joint sheet, a gasket and a packing, for use in junction portions, etc. of pipings of power plant and chemical plant, radiation sheets, electromagnetic wave shielding members, soundproof sheets, etc., and provide a process for producing the composite; a gasket or packing based on the composite and a clay dispersion liquid used for the composite. There is provided a composite composed mainly of graphite and clay and having the structure of graphite laminated with and/or impregnated with clay. The composite is produced by subjecting an exfoliated graphite sheet or film or a molding therefrom to coating with and/or immersion in a clay dispersion liquid with clay particles dispersed therein, or by laminating together of an exfoliated graphite sheet and/or film and a sheet and/or film composed mainly of clay. Further, a gasket or packing is produced by molding the composite.Type: GrantFiled: April 3, 2007Date of Patent: February 11, 2014Assignee: National Institute of Advanced Industrial Science and TechnologyInventors: Takeo Ebina, Yasuhisa Hasegawa, Fujio Mizukami, Nobuhiko Teshima, Katsuro Tsukamoto

Patent number: 7663332Abstract: In a robot with two or more leg links having ankle joint respectively and pivotably linked to a torso, the robot walks naturally by making the ankle joint of a grounded leg link rotate freely by using passive movement. A controller executes controlling operation of calculating target joint angles of remaining joints other than the ankle joint of the grounded leg link based upon the measured joint angles of the ankle joint of the grounded leg link in the lateral and forward direction. The target joint angles of the remaining joints are calculated so as to satisfy the following condition that a tilting angle of the torso matches a target tilting angle determined based upon the measured joint angle of the ankle joint of the grounded leg link in the forward direction, a cycle period of the idle leg link from lifting to grounding, and a target stride of the idle leg link.Type: GrantFiled: September 13, 2005Date of Patent: February 16, 2010Assignee: Toyota Jidosha Kabushiki KaishaInventors: Toshio Fukuda, Yasuhisa Hasegawa, Masahiro Doi, Keisuke Suga, Yoshimi Kajitani
