Publication number: 20170185605Abstract: A file server apparatus includes a memory which stores a program for controlling storage of data of a file in a storage apparatus, and a processor which executes the program. The processor manages a capacity of a storage area of an archive system in which a file stored in the storage apparatus is archived and manages a used capacity of the storage area. When receiving a write request of a file, the processor calculates a used capacity of the storage area of the archive system where a file related to the write request is archived and determines whether or not the file related to the write request can be archived in the archive system based on the capacity of the storage area of the archive system and the calculated used capacity. When determining that archiving cannot be performed, the processor notifies the host computer of an error.Type: ApplicationFiled: September 10, 2014Publication date: June 29, 2017Inventors: Takuya HIGUCHI, Hitoshi ARAI, Sadahiro NAKAMURA, Nobuyuki SAIKA

Patent number: 8670914Abstract: A vehicle brake control system has a braking detector and a braking controller. The braking detector determines whether a braking operation in a vehicle is within an initial braking stage based on a control condition of a frictional braking system. The braking controller performs initial braking stage control during the initial braking stage by controlling a regenerative braking system to provide a limited braking torque and the frictional braking system to provide a supplemental braking torque, the combination of which provides a target braking torque. The braking controller performs subsequent braking control when the initial braking stage ends to provide an increased regenerative braking torque and a lower supplemental braking torque as the target braking torque.Type: GrantFiled: April 22, 2011Date of Patent: March 11, 2014Assignee: Nissan Motor Co., Ltd.Inventors: Noriaki Fujiki, Keigo Ajiro, Takuya Higuchi
