  • Magnetron
    Publication number: 20040239255
    Abstract: A magnetron includes semi-circularly shaped electric field adjusting grooves provided on surfaces of outer ends of vanes brought into contact with an inner surface of a positive polar body to make distribution of an electric field uniform on the surfaces of the outer ends of the vanes. Accordingly, the electric field becomes uniform by the electric field adjusting grooves provided on the surfaces of the outer ends of the vanes, so that generation of undesirable harmonics is suppressed.

  • Audio encoder and decoder utilizing time scaling for variable playback
    Patent number: 6278387
    Abstract: An audio codec having an encoder and a decoder is disclosed. The encoder enables the compression of an audio signal for transmission or storage while the decoder receives a compressed audio signal for playback. A time scaling module within the decoder allows variation of the playback rate of the compressed audio signal. Further, no significant depreciation in the quality of pitch occurs as a result of varying the playback rate. The codec features a control for independently varying the playback rate and a module for delivering pitch compensation. The encoder utilizes a sub-band coding scheme (e.g., MPEG-1 and MPEG-2) wherein an audio signal is split into at least two frequency sub-bands for compression. Using a filter bank having two filters, for example, the audio signal is split into the frequency sub-bands. An decoder having a time scaling module is further disclosed. The time scaling module time stretches or compresses an audio signal as desired using a synchronized overlap and add (SOLA) algorithm.
