摘要： A multilayered helical antenna for mobile communication units includes a first dielectric sheet, a plurality of second dielectric sheets, a plurality of second and third dielectric sheets. All of the second dielectric sheets, except one, have a starting hole and an ending hole, with the exception having the starting hole only. Each of the second dielectric sheet is provided with a partially opened circular metallic pattern. Each of the third dielectric sheets has a via hole. Each of the dielectric sheets has a through-hole at a center thereof in order to allow a whip antenna to be slid upward and downward along a center axis of a helical antenna which is formed by stacking the dielectric sheets in a predetermined order. The via holes are filled with the same conducting material as the partially opened circular metallic patterns to thereby vertically connect the partially opened circular metallic patterns on the second dielectric sheets through the corresponding starting holes and ending holes, thereby forming a spiral capable of transmitting and receiving horizontal and vertical polarizations.

摘要： A nitride semiconductor light emitting device includes n-type and p-type nitride semiconductor layers, an active layer disposed between the n-type and p-type nitride semiconductor layers and having a structure in which a plurality of quantum barrier layers and one or more quantum well layers are alternately stacked, and an electron blocking layer disposed between the active layer and the p-type nitride semiconductor layer. The electron blocking layer has greater bandgap energy than a quantum barrier layer adjacent to the electron blocking layer among the plurality of quantum barrier layers, and has a net polarization equal to or smaller than that of the quantum barrier layer adjacent thereto. The nitride semiconductor light emitting device can achieve high efficiency in every current region by minimizing a net polarization mismatch between a quantum barrier layer and an electron blocking layer.

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.
