  • Publication number: 20050261710
    Abstract: A medical treatment device includes a suturing-ligating member, a stopper, a fixing member and a suturing-ligation releasing member. The suturing-ligating member has a distal end portion, that carries out one of suturing and ligation of biological tissue by puncturing. The stopper is provided to be movable forward or backward on the suturing-ligating member, and stoppable by friction on the suturing-ligating member to maintain the biological tissue in a sutured or ligated state by the suturing-ligating member. The fixing member is provided on the distal end side of the suturing-ligating member to fix the distal end side of the suturing-ligating member to the biological tissue. The releasing member is provided on the distal end side of the suturing-ligating member to release the ligation state maintained by frictional stopping between the suturing-ligating member and the stopper by moving the suturing-ligating member to the distal end portion side with respect to the stopper.

  • Publication number: 20050251618
    Abstract: Data is stored in a non-volatile memory such as a flash memory. The non-volatile memory has two memory areas. When power of a device is turned on, data in the two memory areas are compared to determine which memory area includes old data, and the old data is erased. When the power is turned off, a control setting of the device used immediately before the power is turned off is stored as new data in the memory area from which the old data is erased. When the power is applied again, the new data is read, and the control setting is restored in the device.

  • Publication number: 20040030725
    Abstract: An information reproducing and recording apparatus compares management information corresponding to the program information recorded on the first recording medium and management information corresponding to the program information recorded on the second recording medium, and determines whether or not the management information on the first recording medium is present on the second recording medium. And then, the apparatus acquires attribute information in relation to the program information in cases where it is determined that the management information on the first recording medium is not present on the second recording medium. And then, the apparatus determines, by referring a database having history information including attribute information in relation to the program information recorded on the second recording medium, whether or not the acquired attribute information is present in the database.

  • Publication number: 20030136504
    Abstract: A method is provided for cutting excess synthetic resin 7, which projects from a resin package 6 of an electronic component, at the root connected to the package, the excess synthetic resin being produced in molding the resin package. The excess synthetic resin 7 is cut by laying a thin plate 11 on an obverse surface of the resin package 7 while allowing the excess synthetic resin to penetrate therethrough, followed by moving a cutter 13 along and relative to the obverse surface of the thin plate 13. Alternatively, the cutting is performed by laying a cutter plate and a support plate on the obverse surface of the package 7 while allowing the excess synthetic resin to penetrate through the both plates followed by performing relative movement of the cutter plate.
