A harmonic reducer with clutch function includes a circular spline, a mounting base, a flexspline and a wave generator. When a power source drives the wave generator to rotate in a first direction, a one-way clutch engages to lock the mounting base so as to deform the flexspline and hence rotate the circular spline in the first direction. When an external force is applied to the output shaft in the first direction, the mounting base is driven by the flexspline so the one-way clutch disposed thereon is disengaged by a force in a second direction. At this moment, the rotation speed of the wave generator is equal to zero relative to the flexspline, so the wave generator can be driven by the circular spline to rotate along with the flexspline, and the central axel of the wave generator can be driven to rotate as well.

Small high efficiency motors in order to produce large amounts of power must be operated such that they are running at high speed outside the desired vibration range for sexual stimulation.

A door machine having an electric motor and a chain disk locking mechanism. The chain disk locking mechanism includes a chain disk, an engaging rotary block, a stationary shaft and a plurality of moving pins. When the chain disk is pulled to rotate, the fixed pins of the chain disk press the moving pins so as to push the engaging rotary block to rotate with the stationary shaft together.

In a serial inkjet printing apparatus mounting a plurality of kinds of inks which have different properties and are arranged in parallel, high-speed bidirectional printing is realized without causing an influence of fixing period to prolong output time more than necessary. In order to realize the high-speed bidirectional printing, an order of executing forward print scanning and backward print scanning is controlled so as to further reduce a sum of time required to form an image and time required to wait for the formed image to be fixed. Thus, also in the bidirectional printing, between a forward direction and a backward direction, print scanning in a direction having shorter fixing period is set prior to that in the other direction. Consequently, total time required for image output can be further reduced.
