Patent number: 11687425Abstract: A first server and a second server use a virtual address to mount the storage synchronous area in a storage by the NFS. The first server obtains a snapshot of memory content of a virtual system operated as an active system and transmits the snapshot to the second server. The first server replicates content of the storage synchronous area in the storage to a storage synchronous area in a storage. When a failure occurs in the first server, the second server sets a virtual address to the storage and uses the virtual address to mount the storage synchronous area in the storage by NFS. The second server uses the snapshot received from the first server to execute the application on the virtual system.Type: GrantFiled: March 27, 2020Date of Patent: June 27, 2023Assignee: NEC Platforms, Ltd.Inventors: Teruo Nakamura, Yuji Imai

Patent number: 10235658Abstract: The maintenance management device 3 includes an error status diagnosis unit 11, a grace period estimation unit 14, a maintenance cost estimation unit 15, and a screen display unit 17. When the error status diagnosis unit 11 has diagnosed the occurrence of an anomaly, the grace period estimation unit 14 estimates a first grace period leading up to the occurrence of a failure. The maintenance cost estimation unit 15 estimates the cost of corrective maintenance incurred when the failure occurs after the elapse of the first grace period. The screen display unit 17 displays a combination of the first grace period and the cost of corrective maintenance. Alternatively, the grace period estimation unit 14 estimates a second grace period over which preventive maintenance may be postponed without a failure.Type: GrantFiled: July 10, 2013Date of Patent: March 19, 2019Assignee: Hitachi Construction Machinery Co., Ltd.Inventors: Hideaki Suzuki, Kozo Nakamura, Shinya Yuda, Munetoshi Unuma, Junsuke Fujiwara, Takayuki Uchida, Katsuaki Tanaka, Mitsuo Aihara, Teruo Nakamura, Nobuyoshi Hirowatari, Hiroshi Ogura

Patent number: 9394379Abstract: The present invention provides a water-soluble modified HA practically used as a drug carrier and a production method thereof. The present invention provides: a water-soluble modified hyaluronic acid, the residence time in blood of which is elongated to a practical level, which is produced by introducing a substituent into the carboxy group of the glucuronic acid of hyaluronic acid or a derivative thereof, via an amide bond, at a lower limit of an introduction ratio of 5 mole % or more, using a BOP condensing agent in an aprotic polar solvent; and a production method thereof. Moreover, by cross-linking the modified hyaluronic acid, the present invention provides a hyaluronic acid gel capable of extremely long drug sustained-release even at the same cross-linking functional group introduction ratio as that of the conventionally known gel.Type: GrantFiled: July 22, 2013Date of Patent: July 19, 2016Assignee: CHUGAI SEIYAKU KABUSHIKI KAISHAInventors: Kenji Yasugi, Teruo Nakamura, Tsuyoshi Shimoboji, Mika Sato

Patent number: 8862390Abstract: To advance a dump truck quickly and smoothly to a position where target loading work will be performed relative to an excavating machine, the dump truck is placed in loading target position relative to the excavating machine. Geographic position is detected from GPS satellites of a GPS receiver of the dump truck. The position and direction of the geographic position is transmitted to the excavating machine as a target position image. The target position image and an approach route leading to the position are displayed on a dump truck display when the truck thereafter approaches the position. The dump truck thereafter approaches the position, and the truck is driven so that a current position image advances along the approach route to the target position image, whereby the dump truck is placed in the set loading image target position.Type: GrantFiled: March 27, 2012Date of Patent: October 14, 2014Assignee: Hitachi Construction Machinery Co., Ltd.Inventors: Kazuhiro Sugawara, Hiroshi Ogura, Katsuaki Tanaka, Teruo Nakamura
