摘要： PROBLEM TO BE SOLVED: To provide an electromagnetic acoustic wave inspection device using cross-correlation method for material surface inspection which can solve a problem such that an erroneous detection occurs because random noises prevent a small ultrasonic wave reflected by a surface defect from being detected due to low transmit-receive efficiency of ultrasonic wave.
SOLUTION: An electromagnetic acoustic wave probe for sending an ultrasonic wave and an electromagnetic ultrasonic wave probe for receiving an ultrasonic wave are located to face each other with a small clearance on the surface of an object to be inspected. The electromagnetic acoustic wave prove for receiving an ultrasonic wave receives a direct ultrasonic wave emitted from the electromagnetic acoustic wave probe for sending an ultrasonic wave and propagates in the clearance, and a defect ultrasonic wave reflected by a surface defect. After the received ultrasonic waves are amplified and digitized by an AD converter, a cross-correction function of the direct ultrasonic wave and the defect ultrasonic wave is calculated, and thereby the defect ultrasonic wave submerged with random noises can be detected.

摘要： PROBLEM TO BE SOLVED: To provide a dual-axle rear wheel type truck preventing slip of driving wheels by a simple inexpensive construction.
SOLUTION: In the dual-axle rear wheel type dump truck 1, a turning frame 8 is fixed to chassis frames 5 and 6, and the dual-axle rear wheels (11, 12) are fixed to the turning frame 8. The turning frame 8 is turnable toward a ground contact surface G with respect to the chassis frames 5 and 6 by a hydraulic cylinder 23. When running a hill in a non-load state during snowfall, the front axle 11 on the driving side in the dual-axle rear wheels is relatively lowered toward the ground contact surface G with respect to the rear axle 12 by turning the turning frame 8 toward the ground contact surface G. Consequently, a load carrying ratio of the front axle 11 is increased, and a road surface gripping force of the front axle 11 on the driving side is ensured to prevent or suppress the occurrence of slip.

摘要： PURPOSE:To obtain an accurate complex amplitude signal by processing the real part signal and imaginary part of the complex amplitude signal by Fourier transformation and finding such a phase correcting value that the phase difference of a Doppler shift frequency component is 90 deg.. CONSTITUTION:A quadrature detector 1 is equipped with a phase shifter 4 which makes a 90 deg. phase shift and such a phase correcting value that the phase difference of the Doppler shift frequency component is 90 deg. is found by processing the real part signal and imaginary part signal by Fourier transformation, thereby make phase corrections, frequency by frequency. Namely, the phase correcting value DELTAphid with which the phase difference between the center frequency component of the real part signal and the center frequency component of the imaginary part signal becomes 90 deg. is calculated. Then, phase corrections proportional to DELTAphid are made for either the real part signal or imaginary part signal by all frequency components in an effective frequency band. Consequently, the accurate complex amplitude signal is obtained.
