  • Publication number: 20070136717
    Abstract: A list creating apparatus includes a CPU. A superior directory which manages a plurality of subordinate directories is stored in a plurality of clusters formed in a recording medium. The CPU designates in turn each of the plurality of clusters, and designates in turn a plurality of sectors forming the designated cluster. The CPU also determines whether or not the designated cluster is an end cluster, and further determines whether or not the designated sector is an end sector. The data stored in the designated cluster is read when the determination result as to the designated cluster is negative. The data stored in the designated sector is read when the determination result as to the designated cluster is affirmative, and the determination result as to the designated sector is negative. A subordinate directory name included in the read data is added to a directory list.

  • Patent number: 7162292
    Abstract: With the beam scanning probe system for surgery, a pointer indicating the observation point of a beam scanning probe is superimposed upon an image of a lesion to be operated on in the head which is obtained via a TV camera or a surgery microscope, and the superimposed image information is registered as such in an image recording device. With the beam scanning probe system for surgery, information of a cytological picture is also registered in the image recording device. With the beam scanning probe system for surgery, the image recording device registers the two image information in a paired fashion. Through this arrangement, the beam scanning probe system for surgery can smoothly locate, for a given cytological picture, a site of a tumor to be treated from which the picture was obtained, which will ease the operation.
