20140116244 | PRESSURE CONTROL RESERVOIR WITH CHECK VALVE - A pressure control reservoir for a vehicle brake system is disposed in a hydraulic line extending from a master cylinder to a wheel cylinder through a pump. The pressure control reservoir includes a check valve which consists of a valve seat and a valve. The check valve is closed when an excessive pressure of brake fluid produced by the master cylinder. The valve is stationary. The valve seat is moved in response to an elevated level of the pressure of brake fluid into engagement with the valve, so that the check valve is closed. With these arrangements, the check valve is closed before a piston starts to move to change the volume of a reservoir chamber, thus permitting the volume of the brake fluid required to close the check valve to be decreased, which minimizes the uncomfortable feeling given to a driver of the vehicle when actuating the brakes. | 05-01-2014 |
20140167495 | HYDRAULIC BRAKING SYSTEM - A hydraulic braking system has a brake actuator including hydraulic pumps that generate a W/C pressure by sucking and discharging a brake fluid from a master reservoir, and suck the brake fluid discharged from the W/C side for decompressing a W/C pressure during anti-lock braking. Further, open-when-self-priming valves that suck the brake fluid by themselves from the master reservoir in the hydraulic pumps are provided. Further, an accumulator is provided in a pipe connecting the hydraulic pumps and the W/C, and an accumulation to the accumulator is performed by the hydraulic pumps. Then, communication and cut-off of a pipe connected to the accumulator are controlled by lower limit indicating valves. | 06-19-2014 |

20130201580 | VIRTUAL TAPE DEVICE AND CLEANING CONTROL METHOD - A virtual tape device includes a first drive group of virtual tape drives, a first determination unit, and a first instruction unit. The first drive group is assigned to a first information processing apparatus. The first determination unit determines, upon receiving a first cleaning instruction for cleaning a first virtual tape drive included in the first drive group from the first information processing apparatus, whether the first cleaning instruction is to be output to a physical tape device connected to the virtual tape device. The first instruction unit instructs, when the first determination unit determines that the first cleaning instruction is to be output to the physical tape device, a first physical tape drive corresponding to the first virtual tape drive to perform cleaning. The first physical tape drive is included in the physical tape device. | 08-08-2013 |
20130205081 | VIRTUAL TAPE DEVICE AND TAPE MOUNT CONTROL METHOD - A virtual tape device includes a storage unit, an instruction unit, and a reading unit. The storage unit stores a plurality of logical volumes. The instruction unit receives a request for mounting a specified logical volume from an information processing apparatus. The instruction unit issues a mount instruction to both a physical tape device communicated to the virtual tape device and a virtual device communicated to the virtual tape device when the specified logical volume is not stored in the storage unit. The mount instruction instructs to mount the specified logical volume. The reading unit reads data of the specified logical volume to the storage unit from a device which outputs a mount completion notification first among both of the devices which have received the mount instruction. | 08-08-2013 |
20130205082 | VIRTUAL TAPE DEVICE AND CONTROL METHOD OF VIRTUAL TAPE DEVICE - A virtual tape device includes a storage unit, a cache determining unit, a selector, and a cache controller. The storage unit records logical volume information associated with an identifier of a logical volume, an updated time of the logical volume, information indicating whether the logical volume is allocated to a cache, an identifier of a physical volume storing data of the logical volume, and information indicating whether the physical volume are mounted in a physical tape drive. The cache determining unit determines, based on the logical volume information, whether the logical volume exists on the cache, when a request to store the logical volume on the cache is received and the cache does not have an available capacity. The selector selects the logical volume based on the determined result as an off-cache target logical volume. The selected logical volume is off-cached by the cache controller. | 08-08-2013 |
20130205083 | VIRTUAL TAPE DEVICE AND CONTROL METHOD OF VIRTUAL TAPE DEVICE - A virtual tape device includes a memory to record logical volume information that includes an identifier of a logical volume, an identifier of a physical volume that stores data of the logical volume, and information that indicates whether the data of the logical volume is cached in a cache unit, in association with each other. A determining unit that, when a copy command to copy data of the logical volume stored in a first physical volume to a second physical volume is received, determines whether a logical volume cached in the cache unit exists among the logical volumes, and a storage control unit that, when it is determined that the logical volume cached in the cache unit exists among the logical volumes, stores the data of the logical volume cached in the cache unit to the second physical volume without reference to an order indicated in the copy command. | 08-08-2013 |
20140013068 | INFORMATION PROCESSING APPARATUS, STORAGE SYSTEM, AND WRITE CONTROL METHOD - An information processing apparatus includes a write control unit that executes in parallel a first process in which a writing unit writes, to a storage device, data that are requested to be written to the storage device, and a second process in which a compression unit compresses the data and the writing unit writes compressed data obtained by the compression to the storage device. The write control unit specifies the data written by one of the first and second processes that takes less processing time as valid write data in the storage device. | 01-09-2014 |
20140309981 | STORAGE DEVICE AND CONTROL METHOD - A storage device includes a first storage and a processor. The processor is configured to emulate an access to a physical tape with an access to a second storage. The processor is configured to store, in the first storage, first position information in which a first position in a first physical tape is associated with a storage position in the second storage. The processor is configured to receive an instruction to move data stored at the first position in the first physical tape to a second physical tape. The processor is configured to store, in the first storage, second position information in which a second position in the second physical tape is associated with the storage position. | 10-16-2014 |
