An automatic torque transmission with one or more stages, where each stage has a number of available gear ratios. There is a planetary gear train comprising a planet gear on a planet gear carrier, a sun gear, and a ring gear, wherein an input to the planetary gear train is through the planet gear carrier, and wherein the planet gear is configured to drive the sun gear at higher speed and lower torque, and the ring gear at lower speed and higher torque. There is a first differential gear train having a first input side, a second input side, and an output, wherein the sun gear is coupled to the first input side of the first differential gear train and the ring gear is coupled to the second input side of the first differential gear train, thereby combining two inputs into a single output. A brake clutch is configured to be selectively coupled to the ring gear, to provide selective braking of the ring gear so as to selectively transfer drive from the ring gear to the sun gear. A one-way clutch is configured to be selectively engaged or disengaged from the sun gear, to selectively prevent rotation of the sun gear in one direction. The output of the differential gear train is coupled to either another stage of the transmission or to an output differential gear train. The output differential gear train is configured to be locked for forward drive or coupled to a housing for reverse drive. With the one-way clutch disengaged the sun gear will freewheel by rotating in reverse, with no output.

A vibration motor includes a motor including a rotor including a shaft disposed along a center axis and a stator radially opposed to the rotor, a metal vibrator including a groove in which one end in an axial direction of the shaft is disposed, a caulk that is located at an opening facing in a radial direction of the groove and fixes a circumferential surface of the shaft, and a weld that fixes the vibrator and the shaft at a position different from that of the caulk.

An apparatus for generating a rotary reciprocating motion comprises an input shaft which is driven with unidirectional rotation and an output shaft for delivering reciprocating rotary motion. A first magnetic or ferromagnetic ring is disposed about a rotation axis fixed to the input shaft and a second magnetic or ferromagnetic ring is disposed about the rotation axis fixed to the output shaft. At least one is formed as an arrangement of permanent magnets. The first and second rings are disposed one within the other around the rotation axis. The magnetic coupling between the rings in combination with the effect of an output load results in the desired reciprocating motion of the output shaft.
