Publication number: 20180248429Abstract: An outer rotor motor includes a stationary portion provided with a stator and a rotary portion provided with a magnet portion. The rotary portion is provided with a rotor. An N-pole region and an S-pole region of the magnet portion are alternately arranged in a circumferential direction. The rotor is provided with at least one of a recess portion that is provided on an outer circumferential surface and that is recessed toward a radially inner side and a hole portion that penetrates the rotor in a direction from the outer circumferential surface to an inner circumferential surface. The recess portion and the hole portion radially face the central portion of the N-pole region or the central portion of the S-pole region.Type: ApplicationFiled: February 5, 2018Publication date: August 30, 2018Inventors: Akira SAKAUCHI, Yasuaki SHIMIZU, Takeru KUWAHARA, Musashi NISHIMURA

Patent number: 8302237Abstract: A boarding bridge is provided that has an inexpensive, trouble-free, and strong construction, that eliminates the level differences between the passage portions of adjacent passage sections, and can reduce the occurrence of passengers falling and the like. In the boarding bridge (1), a proximal end tunnel (7) and a distal end tunnel (9) are telescopically fit, and are extended and retracted by moving relative to each other in a longitudinal direction.Type: GrantFiled: January 21, 2009Date of Patent: November 6, 2012Assignee: Mitsubishi Heavy Industries Transportation Equipment Engineering & Service Co., Ltd.Inventors: Yasuaki Shimizu, Kenji Iwamoto, Akira Takarada, Kazunori Yamane

Patent number: 7979937Abstract: It is an object to provide a boarding bridge that can guide passengers to a predetermined gangway at the distal end and in which safety can be improved. A boarding bridge is provided which includes a proximal-end tunnel and a distal-end tunnel telescopically fitted together and capable of relative movement in a longitudinal direction; and a traveling unit mounted at the lower part of a movable leg that supports the distal-end tunnel and moving the movable leg by traveling; wherein the traveling unit includes a pair of traveling devices disposed with a certain distance therebetween in the widthwise direction of the distal-end tunnel, the traveling devices each having an axle rotatable about a vertically extending axis, a plurality of tires rotatably mounted to the axle with a certain distance therebetween, and a traveling motor that rotationally drives the axle; and a rotation synchronizing member that synchronizes the rotation angles of the axles in the pair of traveling devices.Type: GrantFiled: July 28, 2009Date of Patent: July 19, 2011Assignee: Mitsubishi Heavy Industries Transportation Equipment Engineering & Service Co., Ltd.Inventors: Takashi Tomioka, Yasuaki Shimizu, Kenji Iwamoto

Patent number: 7900307Abstract: It is an object to provide a boarding bridge in which differences in level are eliminated between walkway portions of adjacent gangway units so that falling or the like of passengers can be prevented. A boarding bridge is provided in which a proximal-end tunnel and a distal-end tunnel are telescopically fitted and extend and contract by relative movement in a longitudinal direction, wherein, of the proximal-end tunnel and the distal-end tunnel, a variable-length walkway of the distal-end tunnel located on the outside is configured to move between a passage position set at a predetermined height and an outside-of-passage position located lower than the passage position; and the longitudinal length of the passage portion is changed in accordance with a moving distance along with the movement relative to the proximal-end tunnel.Type: GrantFiled: December 12, 2008Date of Patent: March 8, 2011Assignee: Mitsubishi Heavy Industries Transportation Equipment Engineering & Service Co., Ltd.Inventors: Yukio Okahira, Katsumi Tottori, Toshiro Fushiya, Yasuaki Shimizu
