The present invention relates to a semiconductor test device which may use a leakage current and/or a compensation system of leakage current. The semiconductor test device, according to exemplary embodiments of the present invention, may include MOS transistors which may be fabricated in processes similar to those of the semiconductor device. The semiconductor test device may sense the leakage currents which may flow in the MOS transistors, may test whether the semiconductor device may be fabricated normally or abnormally, and may generate at least a normal or abnormal signal as a result. The leakage current compensation device may compensate for the leakage current which may flow in the semiconductor device in response to the normal or abnormal signal of the semiconductor test device. According to exemplary embodiments of the present invention, abnormally-fabricated MOS transistors may be tested and malfunctions of the semiconductor device may be reduced by the leakage current compensation device.

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 refrigerator includes refrigerating and freezing compartments and a cooling cycle mechanism having only one evaporator. When either of the compartments needs to be cooled, the cooling cycle mechanism is started-up and operated to cool the refrigerating compartment, but not the freezing compartment, until refrigerant pressure in the evaporator reaches a steady state condition. Then, if the freezing compartment needs cooling, it is cooled. Thereafter, if the refrigerating compartment needs cooling, it is cooled. During periods when neither of the compartments needs cooling, the cooling cycle mechanism is shut down, and air from the refrigerating compartment is conducted through the evaporator to defrost the evaporator.

Disclosed are a method and apparatus for providing an emotion expression service using an emotion expression identifier. The method includes collecting emotion evaluations of users about content related to a word or a phrase, the emotion evaluations being performed by the users after the users view the content, and displaying an emotion expression identifier representing the collected emotion evaluations of the users in the vicinity of the word or the phrase. The method and apparatus enable a user to intuitively identify emotion expressions of other users (netizens) in relation to a word or phrase such on a Web page such as a portal site.

An apparatus for loading cartridges holding reactants into reactant chambers of a reactor is provided. The apparatus includes: at least one guide rail which transfers a cartridge; an extraction unit comprising at least one storage portion and a blocking portion, the extraction unit moving between a first position in which the blocking portion blocks an outlet of the guide rail and a second position in which the cartridge is output through the outlet of the guide rail and stored by the storage portion; a transfer unit which moves the reactor so that a chamber of the reactor is aligned with the storage portion; and an insertion unit which moves the cartridge from the storage portion into the chamber of the reactor.

A skew-free dual rail bus driver is provided. The dual rail bus driver includes a first driver outputting first dual signals of the same level, and outputting second dual signals of different levels when a level of a clock changes; a decoder receiving the second dual signals and outputting a single signal; a dual signal controller being triggered due to a change in the level of the second dual signals and outputting third dual signals of different levels in response to the single signal at the same time; and a second driver inverting the levels of the third dual signals output from the dual signal controller and outputting fourth dual signals in accordance with a change in the level of the clock. Accordingly, it is possible to obtain dual rail bus driving signals in which skew does not occur. Also, changes in the phases of dual signals are detected and used as a trigger signal input to an edge trigger flip-flop which is a dual signal controller. Also, signals output from the edge trigger flip-flop are used as dual rail bus driving signal, instead of using a clock delayer.

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.
