Abstract: <P>PROBLEM TO BE SOLVED: To provide an abnormality diagnosing device requiring no setting of a reference value using the past measuring data in determining abnormality.  <P>SOLUTION: A sensor 1 detects vibration generated from a rolling bearing of diagnosing object equipment or an apparatus 10. Only a required frequency band is extracted by a filter 2 from a signal of the detected vibration. Envelope processing is performed on the signal after extraction by an envelope processing part 4. A frequency is analyzed by an FFT arithmetic operation part 6, and is converted into data of a frequency area. From the obtained data, a diagnosing part 7 diagnoses abnormality of the rolling bearing by comparing the size of a basic frequency component of the frequency caused by damage of the rolling bearing with the size of a frequency component of its natural number time.  <P>COPYRIGHT: (C)2003,JPO

Abstract: PROBLEM TO BE SOLVED: To reduce the peak value of the pilot signal part of a code multiplex signal. SOLUTION: Phase shifters 65 in spread spectrum modulating sections 511 -51n of respective channels shift the phase of the signal point position vector of a spread-modulated signal by a predetermined angle. For example, the phase shifter 65 of an (i)-th channel shifts the phase of the signal point position vector by a phase shift quantity θ of the (i)-th channel of 360 deg., with i/N where the number of channels is N. Alternatively, in the case of QPSK spread modulation, the signal point position vector is shifted by a phase shift quantity θ of the (i)-th channel of (π/2).mod (i, 4). In this case, mod (i, 4) is the remainder obtained by dividing (i) by 4.  Through phase-controlling, the phase of the pilot signal part of the spread-modulated signal outputted from a spread modulating section of each channel is shifted and dispersed, and the peak value of the code multiplex signal is suppressed.
