Abstract: A hybrid mobile communication terminal includes a mode setting unit which sets a High Data Rate (HDR) power save mode and an indicator indicating the HDR power save mode when data service cannot be provided through a CDMA2000 1x EVDO (Evolution Data Only) system; and a data communication unit which attempts to acquire a CDMA2000 1x system or the EVDO system according to whether the indicator has been set by the mode setting unit. A method for acquiring a system for data service includes: setting an HDR power save mode and an indicator indicating the HDR power save mode when the data service cannot be provided through the EVDO system; determining whether the indicator has been set upon acquiring a system for the data, service; and attempting to acquire the 1x system or the EVDO system according to whether the indicator has been set.

Abstract: Disclosed are a hybrid mobile communication terminal and a method of acquiring a system for data service in the hybrid terminal. The hybrid terminal includes a mode setting unit which sets an HDR power save mode and an indicator indicating the HDR power save mode when data service cannot be provided through the EVDO system; and a data communication unit which attempts to acquire the 1x system or the EVDO system according to whether the indicator has been set by the mode setting unit. The method includes: setting an HDR power save mode and an indicator indicating the HDR power save mode when the data service cannot be provided through the EVDO system; determining whether the indicator has been set upon acquiring a system for the data service; and attempting to acquire the 1x system or the EVDO system according to whether the indicator has been set.

Abstract: A refrigerator includes a cooling system which has a compressor compressing a refrigerant, a condenser condensing the refrigerant compressed from the compressor, a capillary tube converting the refrigerant from the condenser into a low pressure condition, and an evaporator evaporating the refrigerant supplied from the capillary tube. A dryer is provided on a refrigerant line connecting the condenser and the capillary tube to remove impurities included in the refrigerant from the condenser; and a muffler is provided on a refrigerant line connecting the dryer and the capillary tube to decrease a range of fluctuation of the amount of liquid refrigerant flowing from the dryer to the capillary tube.

Abstract: A toll collecting system having a lock-type management for toll collection of vehicles in a toll road such as an express way. The mixed lock-type toll collecting system includes an on-board unit installed in a vehicle which enters an entrance gate and exits an exit gate of the toll road, for toll collection by radio communication; an entrance lane device installed at the entrance gate for transmitting entrance information to the vehicle which enters the entrance gate; an exit lane device installed at the exit gate for collecting the toll from the vehicle which exits the exit gate; and a central control device for controlling the entrance lane device and the exit lane device for toll collection of the vehicle which enters the entrance gate and exits the exit lane of the toll road. A radio communicator is used to provide entrance information to the vehicle by radio communication at the entrance gate for subsequent toll collection upon exit in case radio communication can be performed.
