  • Patent number: 9790727
    Abstract: A vehicle opening and closing body control device includes an opening and closing drive device and a controller. When the opening and closing body is being closed, in a case where the position of the opening and closing body when a trapping of a foreign object is detected is outside a specified range between a fully closed position and a specified position, the controller controls the operation of the opening and closing drive device to reverse the opening and closing body to perform the opening operation by a predetermined opening-and-returning distance and then stop the opening and closing body. In a case where the position of trapping is in the specified range, the controller reverses the opening and closing body to perform the opening operation by the predetermined opening-and-returning distance or a greater distance and then stop the opening and closing body outside the specified range.

  • Patent number: 9677313
    Abstract: A vehicle-door opening/closing control device includes a controller, which controls the operation of a drive device. The controller is configured to supply drive power based on a voltage of an in-vehicle power supply to an electromagnetic clutch. The controller is also configured such that, when stopping an opening/closing body at an intermediate position, the controller supplies the drive power based on the voltage of the in-vehicle power supply to the electromagnetic clutch to put the clutch in the engaged state, and then stops the supply of drive power to the electromagnetic clutch so that the clutch is in the disengaged state after a predetermined holding time has elapsed since the controller has stopped the opening/closing body at the intermediate position. The predetermined holding time differs between a case where the trapping of the foreign object is detected and a case where the opening/closing manipulation is detected.

  • Patent number: 7043131
    Abstract: After a wide-band DCF is wound around a bobbin to form an optical fiber coil 32, the latter is removed from the bobbin and placed into a bundle state (the state where the increase in transmission loss in the wavelength band of 1.55 ?m caused by distortions in winding is reduced by 0.1 dB/km or more) released from distortions in winding. A resin 42 is used as a coil-tidying member so as to secure the optical fiber coil 32 to a storage case 40 at four positions. Both ends of the optical fiber coil 32 are connected to pigtail fibers at fusion-splicing parts 44, respectively. Even when the storage case 40 is closed with a lid after the optical fiber coil 32 is secured to the storage case 40 with the resin 42, there remain interstices within the bundle of the optical fiber coil 32 and a space between the optical fiber coil 32 and the storage case 40. As a result, even when the optical fiber coil 32 in a bundle state is accommodated in the storage case 40, transmission loss and the like would not increase.

  • Patent number: 6731847
    Abstract: The present invention relates to an optical fiber having a large positive dispersion in a wavelength band of 1.55 &mgr;m in order to compensate for a negative dispersion inherent in an NZ-DSF in the wavelength band of 1.55 &mgr;m. This optical fiber comprises a depressed cladding structure constituted by a core region; an inner cladding, provided on the outer periphery of the core region, having a lower refractive index; and an outer cladding having a higher refractive index. In this optical fiber, the relative refractive index difference of the core region with respect to the outer cladding is 0.30% or more but 0.50% or less, and the relative refractive index difference of the inner cladding with respect to the outer cladding is −0.50% or more but −0.02% or less. Also, the optical fiber has a dispersion greater than 18 ps/nm/km at a wavelength of 1.55 &mgr;m, and an effective area of 70 &mgr;m2 or more at the wavelength of 1.55 &mgr;m.
