Abstract: A storage control method executed by a processor included in a storage control device, the storage control device being coupled to a storage including a media cache, the storage being capable of executing a read-modify-write process, the storage control method includes receiving, from the storage, usage information indicating a usage status of the media cache; receiving a write request to write an unaligned data in the storage; transmitting an unaligned data corresponding to the write request to the storage, when the usage information indicates that an available capacity of the media cache is equal to or smaller than a threshold; generating an aligned data from the unaligned data corresponding to the write request by executing the read-modify-write process within the storage control device, when the usage information indicates that the available capacity of the media cache is larger than the threshold; and transmitting the generated aligned data to the storage.

Abstract: A storage control device includes a processor. The processor is configured to request a plurality of disk devices storing data therein to notify the processor of degradation information on degradation of data stored in the respective disk devices. The processor is configured to instruct, based on first information among notified degradation information, the plurality of disk devices to rewrite data. The first information serves as a trigger of rewriting data. The first information is notified by at least one of the plurality of disk devices.

Abstract: In a railway car body formed of hollow shape members 40, a hollow shape member 51 having a shock absorbing function is provided to the ends of a hollow shape member 40 constituting an underframe 30, where impact load is most likely to be received. The hollow shape member 40 is positioned so that the longitudinal direction thereof is arranged along the longitudinal direction of the car body. When impact load is received, the hollow shape member 51 formed at the ends of the member 40 deforms and collapses, thereby relieving the impact force. The present invention simply provides treatment to some areas of the hollow shape members that form the car body without changing the conventional railway car structure greatly, thus minimizing the impact load provided to the passengers upon collision, and improves the safety of the railway car.

Abstract: A car body, in which a hollow shape stock composed of two face plates and ribs joining the face plates together is used to form a side body, and stresses are reduced while minimizing an increase in mass. A car body, comprising a hollow shape stock composed of two face plates (31, 31) and ribs (32) joining the face plates together and used to form a side body (11), wherein face plate portions (31c, 31d) in regions (B, D) above and below connection points (c) between circular arcs, which constitute corner portions of a window (15), and vertical sides of the window (15) are greater in thickness than in the remaining regions (A, C, E). Stresses are most heavily concentrated in the regions (B, D). Therefore, it is possible to achieve reduction in mass and enhancement in strength together. Further, buckling preventive tools can be arranged in spaces in the regions (B, D) of the hollow shape stock.
