  • Patent number: 9224401
    Abstract: An audio signal encoding device includes: a window determination unit for determining the type of window of each channel; a correction unit for correcting the number of available bits; and a quantization unit for quantizing the audio signal of each channel sequentially so that the number of bits is equal to or less than the corrected number of available bits while adding the number of bits left unused, and the correction unit includes: a use rate history calculation unit for calculating a bit use rate in quantization of each type of window; and a corrected bit number calculation unit for correcting the number of available bits so that the rate of used bits to the number of available bits of each channel on the assumption that quantization is performed with the calculated bit use rate in quantization approaches the same.

  • Patent number: 9220079
    Abstract: A signal analysis device includes a synchronization data generation unit, a synchronization correction value calculation unit, and a correction unit. The synchronization unit outputs an A/D-converted correction signal as first synchronization data. The first synchronization data is associated with time based on the timing of a trigger signal input from the outside. The synchronization correction value calculation unit calculates, as a first synchronization correction value, an amplitude ratio, a phase difference, and a time difference between the first synchronization data and second synchronization data input from the outside on the basis of the first synchronization data and the second synchronization data. The correction unit corrects the amplitude, phase, and timing of the RF signal output from the object to be measured, on the basis of the first synchronization correction value or a second synchronization correction value input from the outside.

  • Patent number: 7517507
    Abstract: The steam reformer has a double-cylinder structure having an inner cylinder and an outer cylinder surrounding the inner cylinder. The inner cylinder contains a high-temperature reaction section and an adjacent section being adjacent to the high-temperature reaction section. The high-temperature reaction section contains a mixed-catalyst bed prepared by mixing a steam reforming catalyst and an oxidation catalyst, and an oxygen-containing gas introduction section. A heat transfer suppresser is structured to suppress heat transfer from the high-temperature reaction section to the adjacent section or to the oxygen-containing gas introduction section. With the heat-transfer suppressor, the thermal diffusion from the high-temperature reaction section to peripheral area is effectively suppressed.
