Abstract:
A hybrid vehicle is mounted with a traction motor, a power storage device for storing electric power input to and output from the traction motor, an engine, and a power generation mechanism to generate charging electric power for the power storage device by an output from the engine. An ECU sets charging/discharging electric power of the power storage device to control SOC of the power storage device to be within a predetermined range centered about a SOC control target in a running mode with the engine operating. The output from the engine set to ensure the charging/discharging electric power. The ECU sets the charging/discharging electric power such that the power storage device is discharged to an extent corresponding to a predetermined SOC higher than the lower limit SOC according to requirement power required for vehicle running, even when the SOC is lower than the SOC control target.

Abstract:
To provide a Fresnel lens wherein changes in focal length due to temperature dependence of the refractive index can be compensated. By introducing a fractal structure into prisms in a peripheral region in which the prism angle is large and therefore the aspect ratio h/p of the prisms is large, the aspect ratio is reduced from h/p to h′/p and the slope of the envelope 20 to the underside of the slopping face is reduced, and thereby a shape in which a change in focal length due to temperature dependence of refractive index can be compensated for by a change in the shape of lenses due to expansion/contraction, is obtained.
Abstract:
The invention is directed to a load sharing method in a computer system including a first storage subsystem, a host computer, and a management computer. In the computer system, the first storage subsystem creates a plurality of first logical units from a storage area of a disk drive group, and the host computer creates a logical storage area configured by a plurality of virtual logical units respectively corresponding to the first logical units. A communications path is set between the host computer and each of the first logical units configuring the logical storage area. The load sharing method includes the steps of: monitoring, by the first storage subsystem, a load of its own; and changing, by the first storage subsystem, the communications paths between the host computer and the first logical units based on the monitoring result of the load. With such a configuration, provided is a computer system high in extensibility not deteriorating the performance at the limit of the system after load sharing among the storage subsystems.
Abstract:
A system is provided for storage of journal data from a primary site to a secondary site with a predefined quality of service. In one implementation, the primary storage system stores information for updating data stored on the primary disk array in the form of a history of updates made to the data. The primary storage system is configured to transfer this journal information to the secondary storage system. The user can specify the quality of service desired using a variety of measures, for example, a recovery point objective or a recovery time objective. In response, a copy manager within one of the storage systems determines the capacity of the various primary and secondary volumes, and determines the copy rate available, typically dependent upon the bandwidth between the primary and secondary systems. The copy manager then copies journal data to the remote site where it is stored.

An antenna element made of an electrically conductive material pattern is printed and formed on a face of a casing made of an electrically nonconductive material having a circuit board housed therein, and the antenna element and the circuit board are electrically connected to each other by a connecting element.
Abstract:
A second storage system (SS2) comprises a plurality of tapes, a first storage device capable of performing random access at a rate higher than the tapes, and a virtual storage device emulating the first storage device. A first storage system (SS1) comprises a second storage device and a third storage device that has the virtual storage device mapped therewith. The SS2 reserves a storage space on the first storage device and reads data from the tape corresponding to the virtual storage device into the storage space. The SS1 performs copying between the second storage device and third storage device and, in this process, sends a command for access generated in the third storage device to the virtual storage device. When receiving the Access Command corresponding to the virtual storage device, the SS2 accesses the storage space.

The correspondence between a plurality of virtual storage positions in a virtual volume for logically holding a snapshot image of a main volume in which data elements transmitted from a higher-level device are written and a plurality of address information elements indicating a plurality of actual storage positions of a plurality of data elements constituting the snapshot image is managed. In the initial backup, all the data elements stored in all the actual storage positions indicated by a plurality of address information elements are backed up, then storage positions where a difference has occurred between the virtual volume and the backup destination storage device is managed, and in the next and subsequent backups, data elements on the storage positions specified from the address information elements corresponding to the differentially managed storage positions are backed up.
Abstract:
An antenna device includes a printed circuit board and an antenna element. The printed circuit board has a face a portion of which is formed by a conductive layer overlaid with a magnetic material layer made of anisotropic magnetic material. The magnetic material layer is arranged in such a way that a hard magnetization axis of the anisotropic magnetic material is directed almost parallel to the face. The antenna element is arranged almost parallel to the printed circuit board on a side of the face. The antenna element is arranged in such a way that an antenna current distributed on the antenna element if the antenna element is excited is directed almost perpendicular to the hard magnetization axis.
