  • Patent number: 6404832
    Abstract: A filter device includes a first section for receiving data of a desired cutoff frequency. A second section operates for deciding whether the desired cutoff frequency is in a predetermined low frequency band or a predetermined high frequency band. The predetermined low frequency band is lower in frequency than the predetermined high frequency band. A third section stores data of filter coefficients corresponding to different cutoff frequencies in the predetermined low frequency band. A fourth section stores data of precalculated basic coefficients corresponding to different cutoff frequencies in the predetermined high frequency band. The precalculated basic coefficients are equal to values resulting from a part of calculation to provide final filter coefficients. A fifth section operates for calculating final filter coefficients from precalculated basic coefficients through a coefficient expanding process.

  • Patent number: 6214136
    Abstract: The film boiling state of a refrigerant is maintained for a time longer than in the prior art by t to lower the nuclear boiling start temperature to a temperature at which the material proof strength of a work exceeds thermal stress, thereby lowering the cooling rate of the work. In addition, by controlling the cooling rate in hardening, the film boiling state of the refrigerant is maintained to a temperature at which the material proof strength exceeds thermal stress, thereby cooling the work at a temperature equal to or higher than the critical cooling rate of the work.
