A clothes washing machine has a motor which includes a stator, and a rotor disposed around the stator. The rotor includes a disk-shaped plate having radial blades disposed on an upper surface thereof. The blades are situated beneath the stator and generate a flow of turbulent cooling air along the stator in response to rotation of the rotor.

An apparatus for driving a photosensitive belt is applied to an electrophotographic printer in which a continuously moving photosensitive belt is scanned by an optical beam, thereby forming a latent image on the photosensitive belt for a developer liquid to be applied. The apparatus for driving the photosensitive belt includes a photosensor, a controller and a stepping motor. The photosensor is installed at a position near to the rear end of the scanning area for generating a pulse signal whenever a unit scan line of the photosensitive belt has been completely scanned by the optical beam. The controller processes the pulse signal and drives the stepping motor to rotate a predetermined angle to thereby move the photosensitive belt a unit scan line distance whenever the driving pulse signal from the controller is applied thereto. In this way, the speed of the photosensitive belt will not be excessive so as to prevent complete scanning of each scan line of the optical beam.

A washing machine includes a water tub, a spin basket mounted inside the water tub, a pulsator mounted in the spin basket, a reversible motor mounted under the water tub for driving the pulsator and spin basket, and a damping device for damping external impacts applied to the motor. The damping device is mounted to an underside of the motor and is received in a recess formed in an upper end of a cushioning member disposed beneath the machine during shipment to stabilize the motor.

A brushless motor for driving a washing machine includes a stator fixed to a frame and having a shaft holder with a hollow portion and a yoke wound by a coil; a rotor having a shaft rotatably supported within the hollow portion of the shaft holder; and a flange having a passing hole connected to an upper portion of the shaft holder. The shaft protrudes from the upper portion of the shaft holder and includes a stepped portion having a diameter larger than that of the passing hole.

A conic fluid bearing includes a bush fixed to a rotary body. The bush has upper and lower portions on which conic cavities are opposingly formed, respectively. Upper and lower cones fit on a shaft fixed to a fixed body and are rotatably combined with said upper and lower conic cavities, respectively.

Conic fluid bearing and head drum and spindle motor each including the

A clothes washing machine includes a water tub, a spin basket, and a clothes agitator. A vertical dehydrating shaft is fixed to the spin basket, and a laundering shaft extends coaxially within the dehydrating shaft. Upper and lower ends of the laundering shaft are connected to the agitator and a motor respectively, whereby rotation of the motor is always transmitted to the agitator. In order to selectively connect the dehydrating shaft to the laundering shaft (e.g., during a spin-drying operation), a connecting gear is mounted on the dehydrating shaft for rotation therewith and for vertical movement relative thereto. A power-driven actuator is provided for selectively moving the connecting gear up or down. When the connecting gear moves down, lower teeth thereon become operably connected to the motor so that the dehydrating shaft and laundering shaft rotate together. During a washing or rinsing operation, the connecting gear is moved up, whereby upper teeth thereon become connected to a fixed element, whereby the dehydrating shaft is fixed against rotation.
