Disclosed is a motor driven type electric parking brake system. The parking brake system includes a drum that is rotated along with a wheel, first and second brake shoes installed in the drum to apply brake force to the drum, an operating lever that supports the two brake shoes and pushes the two brake shoes against an inner surface of the drum when a pivoting lever is pulled, a motor to generate drive power to drive the pivoting lever, a cycloid speed reducer connected to a rotating shaft of the motor to amplify the drive power, a spindle member rotatably connected to the speed reducer and having a male screw portion, and a nut member having a female screw portion reciprocally screwed to the male screw portion. The nut member is moved in a longitudinal direction of the spindle member and supports an end of the pivoting lever.

A self-cleaning, shell and tube type heat exchanger using a solid particle-water supply system. The heat exchanger includes solid particle supplying means for storing and supplying solid particles to be used in cleaning the heat exchanger tubes, and water supply means for fluidizing the solid particles stored in the solid particle supplying means so as to supply the solid particles into a mixed fluid discharging means, or for directly supplying water to the mixed fluid discharging means. The mixed fluid discharging means sucks the supplied solid particles and water, and sprays the supplied solid particles and water as a mixed fluid from above the vertical heat transfer tube arrangement such that inside surface of the heat transfer tubes can be cleaned. Separating means separates the mixed fluid used in cleaning the heat transfer tubes into solid particles and water, using a gravitational separation method.

Disclosed is a braking system of an automobile, which can produce and store an electric power by means of the energy generated when the automobile is braked, thereby increasing efficiency in energy use, and simultaneously which can perform an anti-lock braking function and a traction control function. In the braking system, a master cylinder generates a hydraulic pressure when the brake pedal is pressed. A variably exhausting pump unit performs a pumping operation by the hydraulic pressure from the master cylinder. A control section senses a traveling state of the automobile and controls so that a proper braking force is applied to a wheel of the automobile. A flow control valve providing the variably exhausting pump unit with the braking force. A generating section generates electricity by means of a bypassed hydraulic pressure according to the order of the control section.
