  • Patent number: 9015444
    Abstract: A method used in an access module that uses a file system to manage a nonvolatile memory of an information recording module enables an available storage space to be calculated in a short time before file data is recorded, and shortens the time required from initialization of the file system to recording. An access module (1) manages information about area management of the file system configured in an information recording module in units of fixed-length blocks. A divisional available storage space calculation unit (103) performs an available storage space calculation process in units of the fixed-length blocks, and completes preparations for recording when detecting a minimum required storage space for recording file data and enables recording of the file data. This shortens the time required from initialization of the file system to recording.

  • Patent number: 7873432
    Abstract: A position change section of a processing device changes the position of a treatment object, at the time of performing a process by a process section, to correspond to a predetermined position in conformity to the treatment object. An inspection device inspects the occurrence of a defect on the treatment object having been subjected to processes by a plurality of processing devices. Then an analyzing process for specifying in which processing device the defect occurred is carried out based on (i) positional information of the treatment object, in each of the processing devices, and (ii) defect information defected by the inspection device. With this arrangement, during the process of manufacture of treatment objects, it is possible to precisely specify which processing device or processing device group caused the defect, without performing processes such as attaching, to the treatment object, information regarding processing devices which have conducted processes.
