    摘要: A semiconductor fabrication apparatus, located in an apparatus installation area, includes a front-opening unified pod (FOUP) index, a plate, a first transfer device, a second transfer device, and an engineering FOUP index and multiple processing chambers. The FOUP index can be located in a line, vertically, horizontally, on top, and on bottom. The engineering FOUP index is used for manually locating the FOUP thereon in case of processing irregular single wafers that are not stored in a lot. As the FOUP index is located in the semiconductor fabrication apparatus installed in the apparatus installation area, dead space between the apparatus and air eddies generated above and below the FOUP index can be eliminated to increase the efficiency of working area and improve the environment in fabrication.

    摘要: In a radio receiver for receiving vestigial sideband (VSB) signals including symbol codes descriptive of digital signals, HDTV signals being exemplary of such VSB signals, a tuner provides for selecting one of channels at different locations in a frequency band used for transmitting such VSB signals. The tuner also includes mixers for performing plural conversion of the selected channel to a final intermediate-frequency signal, which is digitized by an analog-to-digital converter. A phase tracker, operative on narrow-bandpass filtered portions of the digitized final intermediate frequency signal centering on its carrier frequency, suppresses an imaginary portion of the final intermediate-frequency signal, arising from multipath distortion or from phase incoherency in local oscillations used during frequency conversion. A digital controlled oscillator in the phase tracker supplies digital descriptions of the carrier wave for the final intermediate-frequency signal to a synchronous detector, which synchronous detector detects the real portion of the digitized final intermediate-frequency signal in accordance with those digital descriptions of the carrier wave pair of all-pass digital filters, which exhibit a constant .pi./2 difference in phase response for the digitized bandpass signals and are designed based on Jacobian elliptic functions as described by C. M. Rader, are used in the phase tracker for generating the real and imaginary portions of the digitized final intermediate-frequency signal.

    摘要: Context-based adaptive arithmetic coding and decoding methods and apparatuses with improved coding efficiency and video coding and decoding methods and apparatuses using the same are provided. The method for performing context-based adaptive arithmetic coding on a given slice in an enhancement layer frame of a video signal having a multi-layered structure includes steps of resetting a context model for the given slice to a context model for a base layer slice at the same temporal position as the given slice, arithmetically coding a data symbol of the given slice using the reset context model, and updating the context model based on the value of the arithmetically coded data symbol.
