    Abstract: A dual-shaft clutch varying speed device includes a drive unit, an input shaft, an output shaft, a housing, at least an odd-numbered clutch unit and at least an even-numbered clutch unit. The input shaft having an input gear is coupled with the drive unit. The output shaft, having an end thereof penetrate through the input shaft and the drive unit, has at least an odd-numbered output gear and at least an even-numbered output gear. The housing has a housing gear. The at least one odd-numbered clutch unit being furnished at the inner part of the housing has an odd-numbered clutch shaft and an odd-numbered clutch gear which is meshed with the odd-numbered output gear. The at least one odd-numbered clutch unit has an even-numbered clutch shaft and an even-numbered clutch gear which is meshed with the even-numbered output gear.

    Abstract: An ultrasonic linear actuation device includes a mover and a plurality of stator sets. The mover includes at least one mover rack. The plurality of stator sets is located in correspondence with the mover. Each of the plurality of stator sets includes an actuating component and a plurality of stator racks. The actuating component is used for stimulating corresponding one of the plurality of stator sets to generate standing-wave oscillations in an oscillation direction, such that the plurality of stator racks of each of the plurality of stator sets can engage the at least one mover rack of the mover to allow the stator racks to mesh the corresponding mover rack and thus to displace the mover in a moving direction.
