  • Publication number: 20140238168
    Abstract: An electric linear actuator has a housing with an electric motor, a speed reduction mechanism and a ball screw mechanism. The ball screw mechanism converts the rotational motion of the electric motor to an axial linear motion of a drive shaft. The ball screw mechanism has a nut and a screw shaft. The screw shaft is inserted into the nut, via a large number of balls. The screw shaft is rotationally supported on the housing but is axially immovable. An output gear, forming part of the speed reduction mechanism, is secured on the nut. The bearings are arranged at either side of the output gear. The bearings are mounted on the housing, via a ring-shaped washer, formed from an elastic member.

  • Patent number: 8650977
    Abstract: An electric actuator has a housing (2), an electric motor (3), a speed reduction mechanism (6), a ball screw mechanism (8) and a rotation sensor (9). The ball screw mechanism (8) has a screw thread shaft (23) that moves axially but cannot rotate relative to the housing (8). A nut (24) is inserted over the screw thread shaft (23) and can rotate relative to the housing (2), via a rolling bearing (11), mounted on the housing (2), but cannot move axially. A swing link (13) is arranged to perform the pendulum motion interlocked with the linear motion of the driving shaft (7). A magnet (18) is mounted on the end of a pivotal shaft (17) to form the reference point of the pendulum motion. The position of the driving shaft (7) is detected by the rotation sensor (9) arranged opposite to the magnet (18) via a predetermined air gap.

  • Publication number: 20140047299
    Abstract: A control device for a vehicle including a nonvolatile memory which is electrically erasable and writable detects, on start-up, whether or not an error occurs in updated data read from the nonvolatile memory, and when an error has been detected, performs a reset after saving error information. When being restarted by the reset, the control device for a vehicle determines on the basis of the error information whether or not there is updated data in which an error has occurred, and when there is updated data in which an error has occurred, overwrites the updated data with a fixed value prior to the error detection. Accordingly, there can be suppressed a case in which the error detection is performed while the updated data with an abnormality is present causing the reset and the error detection to be repeated.

  • Patent number: 8290609
    Abstract: The invention provides a production management system and a production management method which are applied to an optical display device production system which can more precisely carry out a production management. A memory stores a panel information allocated per an optical display unit, and a roll information including a positional information of optical films in a material roll before the optical films bonded to the optical display unit are cut so as to coordinate. A position in the material roll before the optical films bonded to the optical display unit are cut is specified based on the panel information corresponding to the optical display unit of the optical display device determined by an inspecting apparatus that a defect exists, and the roll information coordinated to the panel information. If it is possible to recognize what position in what material roll the defect exists, as mentioned above, it is possible to carry out a production management more precisely.
