摘要： An apparatus and a method of compressing and expanding a video signal. The apparatus includes a variable length coder controller and a quantizer. The coder controller compares a bit amount generated in the use of an optimum symbol with that in the use of an existing symbol upon detection of a scene change and outputs a new symbol upon the presence of a gain in accordance with the compared result. A frame delay delays input image data in a unit frame, a subtracter for subtracting an output signal of the frame delay from the input image data, and a scene change detector for detecting a scene change of the input image data. A motion detector detects a motion in the input image data, a main codebook for forming variable sub-codebooks for a still picture, a codebook controller for selecting a specified portion of the main codebook and variable sub-codebooks, and a vector formation unit for forming the input image data into a vector. A distortion measurement unit obtains a codeword with a minimum distortion using the variable sub-codebooks if the input image data is the still picture and using the main codebook if the input image data is a motion picture, and a code assignment unit for assigning a proper code to an output signal from the distortion measurement unit.

摘要： A concentration cooling apparatus for a refrigerator includes a housing which is mounted in a cold air guiding path, and a nozzle which is rotatably supported in the housing, for concentratedly injecting cold air to a region where a high temperature load is generated when the high temperature load is generated in a predetermined region inside a cooling chamber. An infrared sensor is mounted at the front of the nozzle, for sensing the region where the high temperature load is generated. The sensor rotates together with the nozzle and a frost drying sensor is installed on the upper surface of the nozzle, for drying frost on the surface of the infrared sensor. Thus, the reliability of the infrared sensor can be improved by preventing the formation of frost on the surface of the lens of the infrared sensor which detects whether the high temperature load is generated.

摘要： A suction muffler in a reciprocating compressor is installed over a suction valve to attenuate complex sound pressure (noise) such as vibrational noise, valve sonance, flowing noise and pulsative noise produced from the suction valve when low temperature, low pressure refrigerant gas ejected from an evaporator is sucked into a cylinder via the suction valve and a suction portion of the cylinder. A Tesla valve having two distribution paths is mounted in the suction muffler to attenuate the complex sound pressure (noise) while preventing the reflow of the refrigerant gas into the suction muffler from the suction valve. As a result, the Tesla valve also enhances the cooling ability of the compressor and the attenuation effect.
