Patent number: 7191049Abstract: When an own vehicle makes a follow-up traveling control targeting a preceding vehicle traveling ahead of the own vehicle, in case where the widthwise movement of the preceding is detected and a second preceding vehicle traveling ahead of the preceding vehicle is detected, the preceding vehicle is regarded as undertaking to pass the second preceding vehicle and acceleration of the own vehicle is inhibited. Further, in a situation where the preceding vehicle and the second preceding vehicle run in parallel, these vehicles can be recognized discriminatingly from each other based on the memorized widths of theses vehicle and the direction of the widthwise movement of the preceding vehicle. Further, when it is judged that the preceding vehicle travels faster than the second preceding vehicle, the target of the follow-up traveling control is changed to the second preceding vehicle.Type: GrantFiled: March 3, 2004Date of Patent: March 13, 2007Assignee: Fuji Jukagyo Kabushiki KaishaInventor: Koji Yajima

Patent number: 6491136Abstract: An elevator apparatus is provided with an elevator path having a restricted height. Under a roping ratio of 1:1, a thin driving unit having a traction sheave 1 and a driving mechanism 2 is positioned between an inner wall 3a of the elevator path 3 and a space occupied by an elevator car 4 rising and falling in the elevator path 3. One end of a suspension rope 7 is fixed to the elevator car 4 in a position below a ceiling 4c of the elevator car 4. With the arrangement, the car 4 can move close to the ceiling 4c of the elevator car 4 effectively. Further, it is possible to reduce respective heights of the elevator path 3 and a building equipped with the elevator apparatus.Type: GrantFiled: March 26, 2001Date of Patent: December 10, 2002Assignee: Kabushiki Kaisha ToshibaInventors: Kiyoshi Kobayashi, Tadashi Munakata, Kosei Kamimura, Yasuyuki Wagatsuma, Hisao Yamamoto, Koji Yajima
