摘要： PROBLEM TO BE SOLVED: To efficiently diagnose the state of the cavity or rotten part in a living tree in a non-destructive manner.
SOLUTION: When the state in a tree is inspected in the non-destructive manner, high-frequency acoustic waves accurately controlled in amplitude and frequency are allowed to enter the tree from a plurality of positions and the acoustic waves propagated through the tree are detected at a plurality of positions to visualize the state in the tree on the basis of the reception signals. On the basis of the speeds of the reception signals at this time, the hardness of the tree, the presence of its cavity or rotten part, and its water content are diagnosed or the size of the cavity or rotten part of the tree is diagnosed on the basis of the energies of the reception signals or the frequency characteristics of the reception signals.

摘要： PROBLEM TO BE SOLVED: To conduct quick measurement by multiplex oscillation, possible by enabling separation of signals oscillated concurrently from a plurality of oscillators. SOLUTION: This non-destructive measuring device is configured so as to transmit or receive at the same time pseudo-random waves with different code arrays from a plurality of oscillators 20 to analyze them, using the fact that pseudo-random code signals with different code arrays have mutually exclusive properties, and conducts analysis therefor. In this manner, only the signal of the individual oscillator is separated to provide an effect the same as that when the oscillations are issued from a plurality of oscillator positions.

摘要： PROBLEM TO BE SOLVED: To rapidly perform the measurement of a wide range, for example, a range of ten several meters or above at once at a relatively low cost without stopping the operation of a structure or equipment and to provide a precise crack evaluating result.
SOLUTION: An oscillation sensor 120 and a detection sensor 124 are attached to the thickness T-part of a measuring target 104 so as to hold a section 104A to be measured in the measured length direction (X-direction) of the measuring target 104. The frequency F of the single frequency signal of a guide wave 102 is determined so that the wavelength λp of a longitudinal wave P becomes shorter than the width W of the measuring target 104 to be outputted. The outputted single frequency signal is converted in phase to transmit a transmission wave consisting of the longitudinal wave P and a transverse wave S as a false random signal, the guide wave 102 being the synthetic wave of the longitudinal wave P and the transverse wave S propagated through the section 104A to be measured is detected as a detection signal by a detection sensor 120 and the correlation of the false random signal and the signal according to the detection signal is taken to evaluate the crack 104B of the section 104A to be measured.

摘要： PROBLEM TO BE SOLVED: To propagate an energy efficiently in a required direction and to measure a distance between long-distance wells accurately even if a casing with a large energy loss is used by pressing an anvil for contacting wall surface being provided on the probing hole side wall of a vibrator in an oscillator to a probing hole wall with a clamping mechanism. SOLUTION: A pair of oscillators 32 is fixed into a well 12 by a hydraulic clamping mechanism 64 with a hydraulic source 68. The oscillator 32 accommodates a piezoelectric element lamination body 34 with axes in a plurality of horizontal directions and is arranged in the axial direction of the well 12. For example, a stainless anvil 42 is provided in front of a piezoelectric element lamination body 34. Then, one edge of the piezoelectric element lamination body 34 is pressed and fixed to a casing via the anvil 42 using a hydraulic piston, thus synthesizing vibration being generated due to the piezoelectric element lamination body 34 and propagating a sufficient energy efficiently to a ground layer even with a low frequency that cannot be outputted by a single piezoelectric element lamination body.
