Abstract: To provide a semiconductor light emitting device which is capable of accomplishing a broad color reproducibility for an entire image without losing brightness of the entire image. A light source provided on a backlight for a color image display device has a semiconductor light emitting device comprising a solid light emitting device to emit light in a blue or deep blue region or in an ultraviolet region and phosphors, in combination. The phosphors comprise a green emitting phosphor and a red emitting phosphor. The green emitting phosphor and the red emitting phosphor are ones, of which the rate of change of the emission peak intensity at 100° C. to the emission intensity at 25° C., when the wavelength of the excitation light is 400 nm or 455 nm, is at most 40%.

Abstract: An information processing apparatus that is connected to a storage device that stores a file includes processing circuitry. The processing circuitry is configured to receive an instruction of an end process during execution of a predetermined process related to the file, determine, after the predetermined process is completed, whether the instruction of the end process was received during the execution of the predetermined process, and execute the end process after it is determined that the instruction of the end process was received.

Abstract: A control device controls an external storage device with a plurality of storage units which can be driven and stopped independently. The control device comprises: a display control unit; a setting unit; and a control signal output unit. The display control unit displays on a display a selection screen that allows a user to select which storage unit from among the plurality of storage units to operate. The setting unit sets a storage unit selected by the user as an operating storage unit to be operated. The control signal output unit outputs to the external storage device a control signal for having the operating storage unit be operated.

Abstract: A storage device that receives writing data with a first data size from a host, and writes data with a second data size that is greater than the first data size. The storage device includes a storage area unit formatted and managed by a file format including user data and specific management data, the user data and specific management data having a size smaller than the second data size, a cache memory having a capacity of not less than the second data size and that stores the specific management data, and a controller that controls reading and writing data from and into the storage area unit and the cache memory, when receiving an instruction from the host.

Abstract: An electronic device has: an operation unit; a power supply unit; an input changeover switch; and a controller. The power supply unit is supplied commercial power and supplies the operating power to the operation unit. The input changeover switch switches between supplying or not supplying the commercial power to the power supply unit. The controller controls the input changeover switch. The controller includes: a power input portion; a control signal input portion; and a switching signal output portion. When the device power is being supplied from a master electronic device to the power input portion and the control signal from the master electronic device is received by the control signal input portion, the switching signal output portion outputs to the input changeover switch a signal instructing to switch and supply the commercial power to the power supply unit.

Abstract: The control device has a fetching unit, a virtual drive creation unit, and an access control unit. The fetching unit fetches, from the external storage device, attribute information relating to data stored in the external storage device. The virtual drive creation unit creates, in the control device, a virtual drive for storing the fetched attribute information. The access control unit controls access to the virtual drive and the external storage device. When an instruction relating to the attribute information is input, the access control unit accesses the virtual drive to fetch the attribute information. When an instruction to read the data from the external storage device is input, the access control unit accesses the external storage device to reads the data. When an instruction to write new data to the external storage device is input, the access control unit accesses the external storage device to write the new data.

Abstract: In a file management apparatus, on detection of the user's file selecting action, a high-speed file processing execution program P2 gives an instruction to a cache driver D2 to read a selected target file from an external storage device and store the read target file into a cache memory CM. When a file processing operation for the selected target file is determined by the file processing program P1, the file processing program P1 gives an instruction to the cache driver D2 to write the target file, which is stored in the cache memory CM, in the memory location represented by a newly specified address in the external storage device. The file management apparatus effectively shortens the time required for executing a processing operation for a file stored in the external storage device.

Abstract: When a hard disk drive 200 is initially connected, the CPU 110 of a personal computer 100 assigns respective drive letters to a virtual CD-ROM drive area 222 and a hard disk drive 224 in the hard disk drive 200, and records information relating the drive letter assignments as drive letter information in the registry. The CPU 110 then executes auxiliary application software stored in the virtual CD-ROM drive area 222 to delete and disable assignment of a drive letter to the virtual CD-ROM drive area 222.
