A mobile terminal having multiple antennas and an antenna information display method of the mobile terminal are disclosed. Downlink signals are received through the multiple antennas, a channel state of each antenna is measured, and whether or not each antenna needs to be adjusted or an actual channel measurement value are displayed based on the measured channel state information and an antenna setting mode. Thus, a user can check an antenna with a poor reception performance by using the antenna adjustment information or the actual channel measurement value for antenna adjustment, and easily adjust the direction of the antennas.

A photoresist supply apparatus is provided. The photoresist supply apparatus includes a lower photoresist sensor and an upper photoresist sensor respectively installed near the bottom and the top of a trap tank to detect a photoresist in the trap tank. A drain line is connected to an upper side of the trap tank to release air. A photoresist-blocking valve is installed at the drain line, the photoresist-blocking valve structured to be opened to release air or closed to prevent photoresist loss according to signals detected by the lower photoresist sensor and the upper photoresist sensor. While the photoresist is supplied into the trap tank, the photoresist-blocking valve is opened to release air. After the photoresist supply into the trap tank is completed, the photoresist-blocking valve is closed to prevent the loss of a large amount of the photoresist through the drain line.

A silicon-on-insulator (SOI) integrated circuit and a method of fabricating the SOI integrated circuit are provided. At least one isolated transistor active region and a body line are formed on an SOI substrate. The transistor active region and the body line are surrounded by an isolation layer which is in contact with a buried insulating layer of the SOI substrate. A portion of the sidewall of the transistor active region is extended to the body line. Thus, the transistor active region is electrically connected to the body line through a body extension. The body extension is covered with a body insulating layer. An insulated gate pattern is formed over the transistor active region, and one end of the gate pattern is overlapped with the body insulating layer.

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.

An electronic expansion valve for a cooling cycle includes a valve housing having intake and exhaust holes and an orifice formed on the exhaust hole. A case is disposed on the valve housing, and a motor is disposed within the case. The motor has a drive shaft extending inside the valve housing. A guide tube is disposed inside the valve housing, the guide tube being vertically or axially movable by rotation of the drive shaft. A needle valve is provided for adjusting an opening of the orifice, the needle valve being mounted on the guide tube. A mechanism is then provided for restricting an axial or vertical movement range of the guide tube and the needle valve, the mechanism being disposed on the drive shaft and the guide tube.

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.

A switching circuit has first type and second type fuse circuits which respectively receive a plurality of input signals, the first type fuse circuit having a switching characteristic opposite to that of the second type fuse circuit. An input stage is commonly connected to the outputs of the first type and second type fuse circuits. The fuse circuits propagate the input signals according to a cut state of fuses therein, such that a signal path of the switching circuit is optimally adjusted through the fuse circuits by a simple fuse cutting operation.
