Patent number: 11035442Abstract: A door moving apparatus includes a motor unit, a first gear, a second gear, an endless belt, a drum, and a rotator. The first gear is mounted on a rotary shaft of the motor unit. The second gear includes a diameter larger than a diameter of the first gear and teeth more than the first gear. The endless belt passes over the first gear and the second gear. A rotary power of the second gear is transmitted to the drum via a rotary power transmission mechanism. The rotator is configured to reduce a separation of the endless belt from a preset running path.Type: GrantFiled: November 30, 2015Date of Patent: June 15, 2021Assignee: AISIN SEIKI KABUSHIKI KAISHAInventors: Sadayuki Makino, Kenta Mori, Eisuke Umemura, Kiyohiro Fukaya, Takemitsu Sumiya, Nobuyasu Miwa, Akihiro Yasui

Patent number: 5949344Abstract: A position sensor including a rotational shaft (7), a plurality of brushes (13, 15, 17, 19) supported by the rotational shaft (7), a housing (3), a printed circuit board (21) fixed to the housing (3), a main conductor (M) provided on the printed circuit board (21) and contacting with the brushes (13, 15, 17, 19) for generating a primary signal in accordance with which a predetermined number of positions has been attained by the rotational shaft (7), and a subordinate conductor (S) provided on the circuit board (21) and contacting with the brushes (13, 15, 17, 19) for generating a secondary signal in accordance with the which a predetermined number of positions has been attained by the rotational shaft (7). The secondary signal keeps the same voltage level around a predetermined position. According to the present invention, the predetermined position of the rotational shaft (7) may be detected accurately. Further, the cost of the position sensor may be reduced.Type: GrantFiled: May 14, 1998Date of Patent: September 7, 1999Assignee: Aisin Seiki Kabushiki KaishaInventors: Keiji Yasuda, Kiyohiro Fukaya
