The detector detects an idle state. The estimating unit estimates an idle period. When the idle state is detected, the determining unit determines whether a first power consumption when writeback of data which needs to be written back to a main storage device is performed and supply of power to a cache memory is stopped, is larger than a second power consumption when writeback of the data is not performed and supply of power is continued for the idle period. The controller stops the supply of power to the cache memory when the first power consumption is determined to be smaller than the second power consumption and continues the supply of power when the first power consumption is determined to be larger than the second power consumption.07-30-2015

20130219203CONTROL DEVICE, CONTROL METHOD, COMPUTER PROGRAM PRODUCT, AND ELECTRONIC DEVICE - According to an embodiment, a power control device includes a storage unit, a monitor, a determining unit, and a controller. The storage device stores a look-up table, which includes relationship between needed power consumptions and start-up conditions of an electronic device including a plurality of modules. The start-up condition of the electronic device is determined from the needed power consumption in the look-up table and specifies a power on/off status of the modules in the electronic device. The monitor monitors a voltage or available power supplied by a power source when the electronic device is activated. The determining unit determines a start-up condition corresponding to needed power consumption, which corresponds to the voltage or available power monitored by the monitor, with reference to the table. The controller sets a start-up condition of the electronic device to start up the electronic device in the start-up condition determined by the determining unit.08-22-2013
20140075227CONTROL DEVICE, DATA PROCESSING DEVICE, CONTROLLER, METHOD OF CONTROLLING THEREOF AND COMPUTER-READABLE MEDIUM - A control device according to embodiments comprises a data-copying unit, a data-processing instructing unit, and a power-control unit. The data-copying unit copies data in a first memory to a second memory of which power consumption is less than power consumption of the first memory. The data is to be processed at a first data processing unit. The data-processing instructing unit instructs the first data processing unit to process the data copied to the second memory. The power-control unit switches power for the first memory from a first power to a second power while the first data processing unit is processing the data copied to the second memory. The first power is power supplied to the first memory at a time when the data is copied from the first memory to the second memory. The second power is lower than the first power.03-13-2014

20100024469Refrigerating cycle apparatus - A refrigerating cycle apparatus includes a circulation refrigerant, a compressor, a condenser, an expansion valve, an evaporator, and an internal heat exchanger. The internal heat exchanger is disposed to perform heat exchange between a high pressure circulation refrigerant flowing from the condenser to the expansion valve and a low pressure circulation refrigerant flowing from the evaporator and the compressor. The circulation refrigerant has a property indicating an isentropic line having a gradient greater than a gradient of an isentropic line of a R134a refrigerant and a saturation characteristic curve having a two-phase region enthalpy width smaller than a two-phase region enthalpy width of the R134a refrigerant, on a p-h chart.02-04-2010
