  • Publication number: 20180018231
    Abstract: A storage unit includes a plurality of storage devices that form a RAID group, that are coupled to the same bus, and that communicate with each other. Each of the plurality of storage devices includes a device controller and a storage medium. The plurality of storage devices store each of data and parities generated on the basis of the data, the data and the parities being included in RAID stripes. A first device controller of a first storage device included in the RAID group transmits, to the plurality of storage devices included in the RAID group other than the first storage device, an instruction to transfer the data and/or the parities included in the RAID stripes and restores the data or the parity corresponding to the first storage device of the RAID stripes on the basis of the transferred data and the transferred parities.

  • Publication number: 20180013427
    Abstract: First and second bridging portions (63a and 63b) is disposed so as to form a shock absorbing space (63c) between the sensor accommodating portion (61) and the fixing portion (62), and elastically deformed by external force, and the paired bridging portions (the shock absorbing space (63c)) is caused to function as a shock absorbing portion (63). Furthermore, the sensor accommodating portion (61) is thinner than each pf the bridging portions (63a and 63b), after the sensor accommodating portion (61) is elastically deformed and a contact of a blockage is detected, the first and second bridging portions (63a and 63b) can be elastically deformed to absorb a shock. Therefore, it is possible to significantly reduce a load on the blockage in comparison with the conventional technique. Since the drive unit is reversely driven after shock absorption, it is possible to reduce the load on the drive unit and so forth, and to inhibit the occurrence of inconvenience such as burning.

  • Publication number: 20170342762
    Abstract: In a touch sensor unit, a bracket body is provided with a first protruding portion which is disposed on a vehicle interior side of a base portion, a gap portion is provided between the first protruding portion and the base portion, the height from the bracket body to the distal end of the first protruding portion is smaller than the height from the bracket body to the sensor portion. Therefore, when the sensor portion and the base portion are elastically deformed by contact with a blockage, the elastically deformed sensor portion and base portion enter the gap portion, thereby preventing the sensor portion and the base portion from being pressed against the corner portion of the bracket without increasing the rigidity of the sensor portion and the base portion.

  • Publication number: 20170328112
    Abstract: In a touch sensor unit, since a base portion is provided with a hard resin portion for holding a curved state of a sensor portion deformed in conformity to a curved shape of a door frame of a tail gate, even when the base portion is not fixed to the tail gate, it is possible to hold the curved state of the base portion. Therefore, after the curved base portion is fixed to the tail gate with a double-sided adhesive tape, even if the double-sided adhesive tape is degraded with age, a restoring force of the sensor portion does not remove the double-sided adhesive tape.
