Abstract: The present invention provides a washing machine and method of controlling a drying cycle thereof, by which a laundry can be evenly distributed within a drum rotated at a second speed for a low-speed dewatering cycle during the drying cycle to further enhance a drying effect. Once the drying cycle is initiated, a blower fan and heater are driven to circulate hot air within the washing machine via tub and circulation duct. And, the drum is rotated by applying a first rotational speed for a normal drying cycle and a second rotational speed for a low-speed dewatering cycle with a prescribed duty ratio.

Abstract: A method of controlling a drum-type washing machine facilitates the removal of laundry from the drum after the completion of a wash cycle, by controlling the rotational speed/direction of a drum motor so that a force is applied to the drum, thereby separating the laundry from the inner surface of the drum, which becomes adhered thereto during a dewatering step. The method includes steps performing a wash cycle by respectively completing washing, rinsing, and dewatering steps according to a wash course; controlling the driving of the motor, after completion of the dewatering step, to apply a force to the drum; stopping the driving of the motor to allow the motor to freewheel and slow to a stop; and detecting a rotational speed of the motor as the motor freewheels.

Abstract: A method of controlling a combined washing and drying machine is provided, which decreases the time required for completing the overall process from washing to drying. The method includes steps of inputting an operational command; performing washing and rinsing steps according to the operational command; simultaneously performing a dewatering step and a first drying step after completion of the watering and rinsing steps; and performing a second drying step after completion of the dewatering step. The first drying step may include the driving of a pump, a fan, a heater, and a drum motor, while the second drying step may include the driving of a supply valve in addition to the pump, fan, heater, and drum motor.

Abstract: Structure of a driving unit in a drum type washing machine including a tub for storing washing water, a drum of a metal rotatably mounted inside of the tub disposed horizontal to the ground, or with an angle to the ground for accommodating laundry therein, a shaft connected to the drum mounted inside of the tub through the tub for transmission of a driving force of the motor to the drum, bearings fitted onto outer circumferences of both end portions of the shaft for supporting the shaft, a bearing housing having stator fastening bosses at fixed intervals along a circumference of a central portion thereof for supporting the bearings, a stator having a plurality of magnetic cores each formed by stacking magnetic laminations each having a salient pole projected outward in a radial direction and a rib projected inward in a radial direction, both of which are formed as one unit, frames of insulating material for covering top and bottom surfaces of a magnetic core assembly of the magnetic cores, and coils each woun

Abstract: An operation method and apparatus over Galois Field GF(2.sup.m) using a subfield GF(2.sup.m/2). The operation apparatus includes a conversion circuit for converting the elements represented by a basis of GF(2.sup.m) into the elements represented by a basis of GF(2.sup.m/2); an operation circuit for performing an operation over GF(2.sup.m/2) with respect to the elements represented by the basis of GF(2.sup.m/2); and a reversion circuit for reverting the operated elements represented by the basis of GF(2.sup.m/2) to the elements represented by the basis of GF(2.sup.m), thereby performing high speed operation and simplifying circuit construction.
