Abstract: A combustor includes a distal end portion which forms a nozzle extending along an axis and opening at a distal end; an intermediate portion having a mixing surface which defines a mixing space in which air and fuel are mixed, by gradually expanding to an outer side in a radial direction of the axis from the nozzle to a rear, behind the distal end portion; a proximal end portion which forms a fuel space to which fuel is supplied from outside, behind the intermediate portion; and a plurality of air introduction pipes which penetrate the proximal end portion in a direction of the axis, have a distal end communicating with the mixing space, are arranged in a circumferential direction of the axis to surround the axis, and have a fuel supply hole formed on an inner side in a radial direction of the axis to communicate with the fuel space.

Abstract: A heat flux sensor to be attached to a hole portion defined in a surface of an object includes a body portion having an outer circumferential face, and an exterior end face that is flush with the surface of the object. The body portion includes a plurality of bored holes extending from an outer face other than the exterior end face of the body portion, with respective tips of the bored holes being arranged on the same normal line of the exterior end face. The heat flux sensor further includes a plurality of heat sensors having wiring lines leading to the outer face of the body portion through the bored holes, and a filling material that fills the bored holes to seal the heat sensors.

Abstract: A digitizer for converting an analog signal output from a semiconductor device to a digital signal, includes: N Analog-to-Digital converters (ADC's) (31, 32), which sequentially convert the analog signal output from the semiconductor device to the digital signal, a phase error term being denoted &tgr;; an N-way time interleaving unit (40) which interleaves the digital signals from said ADC's in sequence and produces data sequence; and a Fourier Transformation (FT) processing unit (50) for performing FT processing on the data sequence output from said N-way time interleaving unit, the FT processing unit including a butterfly operation unit (220) which inserts a phase error correcting factor to a butterfly operation performed by said butterfly operation unit, so as to correct &tgr;.

Abstract: An input quadrature modulation signal which is converted into a digital signal is converted into a complex baseband signal in a converter 7. A rough estimation of parameters of the signal is made in a rough signal correction unit 51. Using the estimates, the complex baseband signal is corrected. Utilizing a data detection of the corrected signal, a reference signal which corresponds to a transmitted signal is formed from the detected data in a generator 52. The reference signal and the corrected signal are used to estimate parameters in a fine parameter estimation unit 23.

Abstract: An in-phase component and a quadrature component of a digitized input DQPSK modulated signal are provided from interpolation filters, respectively. An instantaneous amplitude and an instantaneous phase of the input signal for each symbol clock are detected from the in-phase and quadrature components and are fed to adders. At the same time, that one of symbols "0, 0," "0, 1," "1, 0" and "1, 1" which corresponds to the instantaneous phase is detected by a symbol detector. An ideal reference signal generating part generates an ideal amplitude component and an ideal phase component corresponding to the detected symbol and provides them to a parameter calculating part. In an I-Q origin offset detecting part, an I-Q origin offset is calculated on the basis of the relationship between a triangle formed by the current detected vector corresponding to an ideal symbol and a vector detected one symbol clock before and a triangle formed by the said two vectors.
