Patent number: 8789721Abstract: A square can capable of securing high sealing performance even if a curvature radius of a seamed portion at a seamed corner portion is reduced, enabling a reduction in a countersink depth, reduced in size, having excellent sealing ability and storage efficiency and a method and an apparatus for double seaming the square can. A second seaming roll (55) is guided by a model cam for second seaming having a model cam surface for second seaming formed in such a shape that it is swelled from a model cam surface for first seaming outwards at a corner seamed portion (5). Accordingly, the seaming shape of the corner seamed portion (5) is formed in such a shape that the seaming width thereof at the center of the corner seamed portion is larger than the seaming width of a linear sealed portion (4) and is swelled outwards to absorb an increase in sheet thickness at the corner seamed portion.Type: GrantFiled: May 16, 2006Date of Patent: July 29, 2014Assignee: Toyo Seikan Kaisha, Ltd.Inventors: Kei Oohori, Kiyotaka Yoshida, Sunao Morishita, Kanji Kuroda, Norifumi Yasuda, Kazuo Ando, Hisashi Katoh

Patent number: 7713217Abstract: A system for assisting the motion of a body connected through joints provides a system for imparting a suitable torque to the connected body at the time of various turns including the bending of the joints. The torque imparting system has first and second measuring means, a reference work volume determining means, and an external torque determining means. The first measuring means measures the internal work volume of the around-joint leg. The second measuring means measures an external work volume around a joint imparted to the leg. The reference work volume determining means determines a reference work volume based on the internal work volume. The external torque determining means determines an external torque imparted to the leg so as to reduce the difference between the internal work volume of the leg and the reference work volume, based on the external work volume.Type: GrantFiled: June 27, 2002Date of Patent: May 11, 2010Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Yasushi Ikeuchi, Hisashi Katoh, Takashi Hirata
