Abstract: Disclosed is a method for a hub module to perform flow-based processing, which includes: receiving a flow including at least one task; a stored procedure generation allowance step for allowing a DBMS module to generate a stored procedure based on the flow when the received flow is not a previously processed flow, wherein the stored procedure includes at least one of a flow query, meta information, and exception handling information, and the meta information includes execution time of the flow query, execution results, and user information; and a stored procedure call allowance step for allowing the DBMS module to call the stored procedure corresponding to a previously processed flow when the received flow is the previously processed flow.

Abstract: A motor driving device for a refrigerator is disclosed. The refrigerator includes a condenser to condense refrigerant, a fan module mounted to one surface of the condenser so as to blow air; a first circuit unit including a microprocessor to output a speed command signal and a filter unit connected to an output terminal of the microprocessor so as to filter the output speed command signal; and a second circuit unit including an inverter controller to output an inverter switching control signal on the basis of the filtered speed command signal and an inverter to convert an input DC power into a predetermined-frequency AC power by performing a switching operation in response to the inverter switching control signal and to output the AC power to a fan motor contained in the fan module. Thus, when the motor is driven, noise is greatly reduced.

Abstract: A deflection yoke separator is disclosed, and the separator includes a convergence correcting means and a neck holder consisting of two outer pieces and an intermediate piece. The outer lower portion of each of the outer pieces of the neck holder is provided with a reinforcing portion, and the reinforcing portion is provided with an insertion slot. The lower portion of the intermediate portion is provided with a stepped portion for matching the height with the insertion slot, and the stepped portion is provided with a guide projection in the circumferential direction in alignment with the center line of the insertion slot. The correcting means M is provided with an elongate guide slot in its lengthwise direction, and therefore, the correcting means can be slided easily along the guide projection.

Abstract: A deflection yoke capable of damping the leaking magnetic fields leaking to the front of the screen is disclosed. The characteristic feature of the deflection yoke includes: two pairs of ferrite cores opposingly facingly disposed on the flange portion of the beam outgoing side of the deflection yoke; and coils extended from the horizontal deflection coil and wound on the ferrite cores in such a manner as to offset all the magnetic fields other than the main horizontal deflection magnetic field.
