Abstract: The present invention relates to a motor driving control system and a control method thereof. The purpose of the present invention is to provide a motor driving control system and a control method thereof, which may change electric current limiting logic, which is applied to a BLDC motor for a cooling fan, in response to an operating speed of the motor to stably protect the motor from an overload in a low-speed driving state as well as an overload in a high-speed driving state.

Abstract: A composition includes tyrosine-amino acid peptide as effective component. The composition may enhance umami. The amino acid may be lysine, methionine, valine, serine, cysteine, arginine, asparagine, aspartic acid, alanine, isoleucine, leucine, threonine, tyrosine, glutamine, glutamic acid, glycine, histidine, phenylalanine, proline, or tryptophan. The composition may further includes glutamine. The composition may be added to food to enhance umami.

Abstract: A method for a multi-party call in a mobile station is provided. The method includes performing a multi-party call and call-connecting, if a mobile station is selected for call connection from mobile stations connected for the multi-party call, to the selected mobile station. Accordingly, a user can reject a call connection request of a third party during communication through a base station. Further, the user can directly select a desired mobile station for call connection or connection release.

Abstract: Provided are a method and an apparatus for providing a high-speed data service in a portable terminal which supports a 1X-Evolution Data Only (EVDO) system. The method includes if an access to an EVDO data service is performed, setting whether a voice service is to be used; and determining whether a 1X paging channel is to be searched during the access to the EVDO data service, according to the set result. Thus, the portable terminal can set a communication mode during the access to the EVDO data service to enter a mode, which supports only the EVDO data service, without searching for a 1X paging channel.

Abstract: A method for manufacturing a heat exchanger for a cooling cycle includes the steps of: preparing the pipes and the fins having through-holes through which the pipes are inserted, arranging the fins parallel depth-wise and in several separate groups depth-wise and then inserting the pipes through the through-holes of the fin groups, bending the outer portions of the pipes so that the fin groups separated from each other are piled in layers along the longitudinal direction of air flow and the inner portions of the pipes are arranged in at least two coplanar rows along the longitudinal direction of air flow, and wrenching the bending portion of the pipes to form each pipe row into a zigzag shape.

Abstract: A refrigerator includes a compressor, a condenser for condensing a refrigerant supplied from the compressor, and a pair of evaporators which are connected in series for evaporating the refrigerant supplied from the condenser. The refrigerator further includes a connection refrigerant tube connecting the pair of evaporators, and an intercooler refrigerant tube extended from the condenser and contacting the outer surface of the connection refrigerant tube for heat-exchanging with the connection refrigerant tube. Accordingly, a tube connection work is facilitated and a refrigerant leakage possibility is lowered.

Abstract: A refrigerating cycle system for a refrigerator has a freezing chamber and a refrigerating chamber. The refrigerating cycle system includes a compressor, a condenser, first and second expansion devices, a first evaporator for cooling the freezing chamber by evaporating the refrigerant that is reduced in pressure by the first and second expansion devices, and a second evaporator for cooling the refrigerating chamber. A fluid passage is provided for directly conducting the refrigerant from the condenser to the first evaporator. Another fluid passage is provided for directing the refrigerant from the condenser to the first evaporator via the second evaporator. A direction control valve is disposed between those two fluid passages to selectively direct the refrigerant to one of those fluid passages as a function of a sensed temperature of the refrigerating chamber.
