  • Patent number: 9281989
    Abstract: A compensation apparatus compensates a quadrature-demodulated signal output from a quadrature demodulator 5 that performs quadrature demodulation by using a signal of a carrier frequency fc, by removing an image component caused by the quadrature demodulator 5 from the quadrature-demodulated signal. The compensation apparatus includes a signal generator 10 that generates a reference signal having a predetermined bandwidth in a reception band, and provides the reference signal to an input side of the quadrature demodulator 5. The reference signal includes a frequency band that is biased to either a higher-frequency side or a lower-frequency side with respect to the carrier frequency.

  • Publication number: 20080196237
    Abstract: A method and apparatus for manufacturing a honeycomb compact-body molding die having material feed bores for supplying material therethrough and slit recesses formed in a polygonal lattice pattern to mold the material in a compact body with a honeycomb shape are disclosed. The slit recesses are formed on a recess forming surface of the molding die using an electrode having electrode segments, formed in a lattice pattern corresponding to shapes of the slit recesses each of which has a wall thickness of 0.1 mm or less, to generate an electrical discharge between the molding die and the electrode to form the slit recess on the molding die. When the electrode is worn by a given amount, an apical end cut-off processing step is executed to cut off an apical end of the electrode using a dress plate to expose a new apical end formed with an electrical discharge surface.
