    Abstract: A duplicate feeding detection device for use with sheet-like members may include a control part for controlling an ultrasonic transmission part, a duplicate feeding judging part for judging duplicate feeding of the sheet-like members on a basis of an output from an ultrasonic receiving part, a temperature measuring part for measuring temperature of a vicinity of the ultrasonic transmission part, and a memory part in which a relationship between an oscillation frequency of the ultrasonic transmission part and a temperature is stored. The control part sets an oscillation frequency corresponding to a temperature which is measured by the temperature measuring part on a basis of the relationship between the oscillation frequency and the temperature stored in the memory part.

    Abstract: Process and apparatus for damping vibrations in a machine for winding material webs, in which the apparatus includes at least two cylindrical bodies. The process includes positioning the at least two cylindrical bodies to roll on each other to form a nip, such that at least one of imbalance and out-of-roundness of either of the at least two cylindrical bodies form a system capable of vibration. The process further includes actively damping vibrational forces of the vibration system in at least one of the at least two cylindrical bodies by displacing an axis of rotation of the at least one of the at least two cylindrical bodies in accordance with a current one of a plurality of vibrational force measurements made per each rotation of the at least one of at least two cylindrical bodies and with additional energy fed from outside of the vibration system.

    Abstract: The paper carrying apparatus includes a first paper carrying mechanism (first carrying mechanism), a second paper carrying mechanism (second carrying mechanism) provided on the downstream of the first carrying mechanism in a carrying direction, an electric motor that drives the first carrying mechanism, a stepping motor that drives the second carrying mechanism, and an acceleration sensor that is a vibration detecting mechanism detecting vibration generated in the rotation shaft of the stepping motor. When the first carrying mechanism and the second carrying mechanism concurrently carry the same paper sheet, the electric motor is controlled in driving velocity based on information of vibration detected by the acceleration sensor at the timing of the rear end of the carried paper sheet passing the first paper carrying mechanism.
