Patent number: 10545684Abstract: A storage device relating to one aspect of the present invention has a storage controller and multiple memory devices. The memory devices manage capacity equivalent to the size of a memory space provided to the storage controller among regions of a non-volatile storage medium as logical capacity and manage the remaining regions as reserve capacity. When a device controller determines that a portion of the memory regions in the non-volatile storage medium is in an unusable state, the device controller notifies the storage controller of the size of the memory regions in the unusable state. On the basis of a policy set by the memory device, the storage controller determines the reduction amount of the logical capacity and the reserve capacity and notifies the memory device of the determined reduction amount of the logical capacity.Type: GrantFiled: May 13, 2015Date of Patent: January 28, 2020Assignee: Hitachi, Ltd.Inventors: Hideyuki Koseki, Masahiro Arai

Patent number: 10436414Abstract: In a door mirror device for a vehicle, a projector protrudes out toward a lower side from a circuit board, and the projector projects a pattern onto a ground surface. Moreover, illuminating LEDs and guide bodies are fixed to a lower surface of the circuit board. Due to the illuminating LEDs generating lights and the guide bodies guiding these lights, the guide bodies irradiate the lights from lower ends, and the ground surface is illuminated. Here, the lower ends of the guide bodies are disposed further toward a lower side than the projector. Therefore, shadows, which are due to the projector, arising in lights that illuminate the ground surface can be suppressed.Type: GrantFiled: November 6, 2015Date of Patent: October 8, 2019Assignee: KABUSHIKI KAISHA TOKAI-RIKA-DENKI-SEISAKUSHOInventors: Kazuyuki Yokoyama, Masatsugu Ohashi, Masahiro Arai

Patent number: 10120592Abstract: A storage subsystem constituting a pool using storage media having rewrite life and providing a logical volume having a virtual capacity to a host, wherein the storage subsystem monitors whether shortage of a remaining rewrite life of the capacity pool will occur or not within an operation period of the storage subsystem, and when it is determined that shortage of the remaining rewrite life will occur, the subsystem converts the rewrite life required to cover the shortage into drive capacity and indicates the same, or indicates the same by reducing an existing pool capacity, and requests maintenance of the subsystem. A maintenance method is provided, wherein elongation of life is executed by adding a capacity to the pool at the time of indication, and as for addition of capacity other than the elongation of life described above, a maintenance fee is charged.Type: GrantFiled: September 26, 2014Date of Patent: November 6, 2018Assignee: Hitachi, Ltd.Inventors: Masahiro Arai, Masahiro Tsuruya
