Patent number: 7681683Abstract: A seat belt retractor includes a seat belt winding device for winding up a seat belt by actuation of a motor and a control unit. The control unit, under a predetermined condition, repeats a process of stopping the actuation of the motor when an overload of the motor is detected and restarting the actuation of the motor after a lapse of a predetermined time period. The control unit includes a timer for clocking the time period from the start to the stop of the actuation of the motor, a counter for counting up the number of times of starting the actuation of the motor, and a determination module that based on the result of the timer and the counter determines whether or not actuation of the motor, which is stopped by the detection of an overload, is to be restarted.Type: GrantFiled: March 21, 2008Date of Patent: March 23, 2010Assignee: Takata CorporationInventors: Masato Takao, Koji Tanaka, Daisuke Murakami

Publication number: 20090236459Abstract: Embodiments of the invention comprise a portable device and a method for rapidly collecting tubing, line, wire, or other long, flexible objects onto a spool. The respooling device comprises a fixed compression nut attached to a threaded rod and an adjustable compression nut removably coupled to the threaded rod. The threaded rod and compression nuts have thread selected for mechanical strength, smooth operation without lubrication, and rapid translation of the adjustable compression nut along the threaded rod. A spool clamped around the threaded rod by the compression nuts is automatically centered on the rotational axis of the respooling device. A driver turns the threaded rod, compression nuts, and spool to wind material onto the spool. Some embodiments respool material at rates greater than 30 feet (9.1 meters) per second. Some embodiments include a cordless driver. Some embodiments include a spool adapted for respooling a particular material, for example shock tube.Type: ApplicationFiled: March 21, 2008Publication date: September 24, 2009Inventors: Christopher J.

Publication number: 20090206190Abstract: Dynamic calibration of a secondary velocity signal is provided in a tape drive. In one example, a reel motor is operated to drive a reel carrying a tape in a tape drive. The motion of the tape is measured to provide a measured primary velocity signal of the tape, and in addition, the operation of the reel motor is measured to provide an estimated secondary velocity signal of the tape as a function of motor parameters and the motor operation measurements. The estimated secondary velocity signal of the tape may be calibrated as the tape is driven, as a function of the tape motion measurements and the motor operation measurements. Other embodiments are described and claimed.Type: ApplicationFiled: February 15, 2008Publication date: August 20, 2009Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Nhan Xuan Bui, Reed Alan Hancock, Wayne Isami Imaino, Haiyu Zhao

Patent number: 7533903Abstract: A seat belt retractor, which is capable of winding and unwinding a seat belt for occupant restraint by an electric motor, warns a vehicle occupant. A seat belt retractor of a seat belt apparatus to be installed in a vehicle is structured such that a motor is controlled to repeat an action of increasing and decreasing the tension acting on a seat belt a plurality of times according to a setting that the seat belt tension at the initial stage of each action overshoots a predetermined target tension, for the purpose of warning a vehicle occupant who wears the seat belt.Type: GrantFiled: August 3, 2006Date of Patent: May 19, 2009Assignee: Takata CorporationInventors: Masato Takao, Koji Tanaka, Koji Inuzuka

Patent number: 7533842Abstract: A clutch 100 of the present webbing retractor has a gear wheel 116 and spring claws 182, and has peripheral direction load receiving portions 120 at the gear wheel 116, and load from the spring claws 182 is applied along a peripheral direction via the peripheral direction load receiving portions 120. Therefore, compactness and weight reduction of the clutch 100 can be aimed for. Further, the clutch 100 has a ring 176, and the ring 176 integrally has a cover portion 178 holding respective clutch structural members at predetermined assembly positions, and the spring claws 182, and is held integrally with a rotor 124 by elastic forces of the spring claws 182. In this way, the respective clutch structural members can be temporarily held (sub-assembled) integrally.Type: GrantFiled: March 31, 2005Date of Patent: May 19, 2009Assignee: Kabushiki Kaisha Tokai-Rika-Denki-SeisakushoInventors: Takuhiro Saito, Katsuki Asagiri, Shinji Mori, Tomonori Kimura
