20140250286 | COMPUTER AND MEMORY MANAGEMENT METHOD - A computer comprising: a processor; a memory; and an I/O device, the memory including at least one first memory element and at least one second memory element, wherein a memory area provided by the at least one second memory element includes a data storage area and a data compression area, wherein the computer comprises a virtualization management unit, and wherein the virtualization management unit is configured to: set a working set for storing data required for processing performed by a virtual machine in generating the virtual machine, and control data stored in the working set in such a manner that part of the data stored in the working set is stored in the data compression area based on a state of accesses to the data stored in the working set. | 09-04-2014 |
20140064056 | NETWORK MANAGEMENT APPARATUS, NETWORK MANAGEMENT METHOD, AND NETWORK MANAGEMENT SYSTEM - A network management apparatus is designed so that when reassigning the existing address, the network management apparatus extracts a link with the largest link cost from among links comprising the network based on the network configuration information and specifies a flow routed though the extracted link based on the statistic information; when receiving a path change request and a via link request to request a via link with respect to the specified flow from an external terminal, the network management apparatus selects either one of addresses of an address pair of the specified flow as a change target address; and when changing the selected change target address, the network management apparatus changes the change target address to a candidate address to be assigned by selecting an address, which is routed through a link included in the via link request and has not been assigned, as the candidate address to be assigned. | 03-06-2014 |
20100114447 | AUTOMOBILE AND CONTROL DEVICE FOR AUTOMOBILE - The invention is to provide an automobile and a control device for the automobile, which permits to obtain a driving performance or a braking performance close to their limits achievable on the concerned road face even such as on a compacted snow road and a frozen road. | 05-06-2010 |
20090218643 | Semiconductor Pressure Sensor - An object of the present invention is to solve problems in that aluminum electrodes, aluminum wires, and I/O terminals are corroded by corrosive gasses when a pressure of a pressure medium containing corrosive matters such as exhaust gas is measured with a semiconductor sensor; and improve not only the corrosion resistance of the sensor chip but also the corrosion resistance of the portion particularly functioning as the pressure receiver. | 09-03-2009 |
