Disclosed is a dense thin film, a fuel cell using the same and fabrication methods thereof. A method for fabricating a dense thin film comprises (1) forming a first thin film on a porous surface, and (2) forming, on a surface of the first thin film, a second thin film made of a homogeneous material with respect to the first thin film, thereby removing pinholes of the first thin film. The method for fabricating a dense thin film may comprise (1′) forming a first thin film on a porous surface, (2′) forming, on a surface of the first thin film, a second thin film made of a to heterogeneous material with respect to the first thin film, thereby removing pinholes of the first thin film, and (3′) etching a surface of the second thin film. A dense thin film comprises a porous material, a first thin film formed on a surface of the porous material and having pinholes, a blocking material including a homogeneous or heterogeneous material with respect to the first thin film and configured to block the pinholes, and a second thin film including a homogeneous or heterogeneous material with respect to the first thin film and formed on a surface of the first thin film.

A multi type air-conditioner is provided. The multi type air conditioner includes an outdoor unit having a plurality of outdoor heat exchangers that heat-exchanges with outdoor air and a compressor that compresses a refrigerant; a plurality of indoor units that performs either cooling or heating; a high pressure pipe connected between a discharge side of the compressor and the plurality of indoor units; a low pressure pipe connected between a suction side of the compressor and the plurality of indoor units; and a refrigerant exhauster provided between the high pressure pipe and the low pressure pipe. The refrigerant exhauster discharges a liquid refrigerant to the low pressure pipe when the liquid refrigerant is accumulated in the high pressure pipe, whereby degradation of cooling capability due to a lack of refrigerant may be prevented by minimizing accumulation of the liquid refrigerant in the high pressure pipe in a cooling operation mode.

A voltage generating circuit includes a first storage unit, a second storage unit, and a voltage generator. The first storage unit stores first voltage data, and the second storage unit stores second voltage data. The voltage generator generates a voltage corresponding to one of the first and the second voltage data according to whether the second voltage data is changed from the first voltage data.

A watch-type portable terminal includes a first housing and wrist bands extending from both ends of the first housing. The watch-type portable terminal includes a second housing rotatably combined with the first housing in a direction to be folded down or away from the first housing while facing the first housing. Display devices are installed on at least one face of the second housing.
摘要:
An apparatus for testing an air conditioner is disclosed. The apparatus includes a first wireless device connected to the air conditioner, and a second wireless device connected to a test terminal. The first wireless device transmits and receives test result information and test-related information based on a testing program installed in the test terminal in a local-area wireless communication manner, and the second wireless device transmits and receives the test-related information and test result information based on the testing program in the local-area wireless communication manner. Therefore, local-area wireless communication can be carried out between the air conditioner and the test terminal, thereby making it possible to significantly save trouble for installation of testing instruments, such as cables and a converter, and to significantly curtail costs and manpower for test work.
摘要:
A poly-silicon (poly-Si) thin film transistor (TFT) having a back bias effect is provided in order to enhance characteristics of a leakage current, a sub-threshold slope, and an on-current. The poly-Si TFT includes a glass substrate, an island type buried electrode pad formed of an conductive material on one side of the glass substrate where the back bias voltage is applied, a buffer layer formed of an insulation material on the whole surface of the glass substrate, and a poly-Si TFT formed on the upper portion of the buffer layer. A method of fabricating the TFT is also provided.
摘要:
The present invention relates generally to a method for forming a pattern, and in particular, to a method for forming a pattern for the formation of quantum dots or wires with 1˜50 nm dimension using the atomic array of a single or poly crystalline material. The electron beam lithography method preferably uses the phase contrast atomic image of a single or poly crystalline material itself.
摘要:
A circuit for discriminating between received signals and a method therefor are provided. The circuit includes a detector for detecting a peak signal based on the degree of correlation between a received signal and a reference signal and a generator for generating a discrimination signal showing that the received signal is a high definition signal if the peak signal is detected in a predetermined period and showing that the received signal is a signal of an analog broadcasting method if the peak signal is not detected in the predetermined period. This can prevent the improper operation of a receiver by automatically determining whether the received signal according to a channel selection is a high definition digital signal or an analog broadcast signal.
