摘要:
A recording device control apparatus that successively receives transfer requests and controls transfer of data relating to the transfer requests to and from a recording device, each transfer request including (i) area information that shows an area that is a transfer destination or a transfer source in the recording device and (ii) type information for specifying a transfer data type, the recording device control apparatus including: a reception unit operable to receive the transfer requests; a transfer request specification unit operable to perform transfer criterion judgment processing and same-area judgment processing with respect to each of specification target requests which are received transfer requests whose related data has not been transferred, and, when a targeted transfer request fulfills a condition of a negative judgment result in both of the processing, specify the related data of the targeted transfer request as a transfer target, the transfer criterion judgment processing being for judging whether or not the targeted transfer request is a transfer-withhold target, based on a predetermined transfer criterion that defines a transfer order for the targeted transfer request and one or more transfer requests having different type information to the targeted transfer request, and the same-area judgment processing being for judging whether or not a transfer request that has area information identical to area information included in the targeted transfer request was received before the targeted transfer request was received; and a transfer unit operable to transfer the data specified by the transfer request specification unit. By transferring data to the same area in the order specified by the transfer specification unit, inconsistencies are avoided in the data in the recording device.
摘要:
A recording device control apparatus includes a reception unit operable to receive transfer requests and a transfer request specification unit operable to perform transfer criterion judgment processing and same-area judgment processing. When a targeted transfer request fulfills a condition of a negative judgment result in both processes, the apparatus specifies the related data of a targeted transfer request as a transfer target. The same-area judgment process is for judging whether or not a transfer request that has area information identical to area information included in the targeted transfer request was received before the targeted transfer request was received. Furthermore, the apparatus includes a transfer unit operable to transfer the data specified by the transfer request specification unit. By transferring data to the same area in the order specified by the transfer specification unit, inconsistencies are avoided in the data in the recording device control apparatus.

A data recording apparatus is provided with a recording medium. In addition, the data recording apparatus is provided with a file data list management unit and a file index list management unit. The file data list management unit receives file data constituting a plurality of files, on a file-by-file basis, and then records the received file data to the recording medium. Upon completion of the recording of the file data to the recording medium, the file index list management unit generates specification information associated with the files to which the received file data relates. The file index management unit then records the generated specification information to the recording medium 107.

A file management apparatus, a file management method, and a computer-readable recording medium in which a file management program is recorded, are provided which are capable of certainly detecting an alteration to a volume. An HDD 130 stores a file, and stores volume management data 152 for managing a volume which includes the file; a copyright-data creation section 205 creates volume copyright data 134 for detecting an alteration to the volume management data 152 when the file is written; a flash RAM 132 which is disposed in a position physically different from the HDD 130 stores the volume copyright data 134; a copyright-data comparison section 206 compares the volume management data 152 and the volume copyright data 134 when the volume is mounted; and a control section 202 mounts the volume if a decision is made that there is no alteration.
摘要:
When a plurality of operators perform pointing operations, a pointing control device selects a pointer for determining a position to be pointed from among the operators by using the distance between a face and a fingertip or a substitute for a fingertip of each operator. The pointing device calculates the distance between the face and the fingertip or the substitute for each operator by using a position of the face and a position of the fingertip or the substitute, selects a pointer from the operators by using the calculated distance, and calculates a position of a cursor for a pointing operation based on the position of the fingertip or the substitute calculated for the selected pointer. A pointer can be selected regardless of the number of operators, and a pointer can easily change to another operator.

An optical processing apparatus includes an emitter for emitting light, a first light path for directing the light to a position to be processed on a workpiece, and a processing head. The processing head includes an optical system provided in the first light path, for shaping the light, a second light path having a portion shared with the first light path, the second light path directing light reflected from the workpiece, and an optical receiver for receiving the reflected light from the second light path. The optical processing apparatus further includes an actuator for changing a positional relationship between the optical system and the workpiece, a feeder for supplying a solder to the workpiece, a first shifter for moving the processing head in a first direction in parallel to an optical axis of the light emitted from the emitter, a second shifter for positioning the feeder in the first direction away from the processing head when the processing head is moved away from the workpiece by the first shifter, and a third shifter for moving the feeder against the processing head in a second direction perpendicular to the first direction while the processing head is moved by the first shifter. The optical processing apparatus allows the spot of the incident light and the position of soldering to be readily set depending on the configuration of a workpiece and can thus solder the workpiece at higher quality under soldering conditions optimized for the workpiece.
