摘要： PURPOSE:To make it possible to ensure the measurement of a gap even if a heat transfer pipe has a thin wall, by a constitution wherein an ultrasonic wave probe that is inserted into the heat transfer pipe is positioned at a point that is offset from the central axis of the pipe, and an ultrasonic wave is inputted into the inner surface of the heat transfer pipe at an angle at which the ultrasonic wave that is orthogonal to the supporting surface of a supporting member in parallel with the central axis is transmitted. CONSTITUTION:An ultrasonic wave probe 4 is inserted into a heat transfer pipe 7 so that the probe is offset from the central axis of the pipe. When an ultrasonic wave 6 is transmitted from the probe 4, the sound wave 6 is obliquely inputted into the inner surface of the heat transfer pipe 7 owing to the offset position. A reflected wave 6a advances in the different direction from the probe 4. A part 6b of the ultrasonic wave 6 is refracted at the inner surface 7a, propagated through the material of the heat transfer pipe 7 and obliquely inputted into an outer surface 7b. The wave is propagated between the inner and outer surfaces 7a and 7b in a zigzag pattern. The wave is received with the probe 4 and selected. A part 6c of the reflected wave 6b is transmitted through the outer surface 7b, propagated so that the light crosses a supporting surface 8a of a supporting member 8 and undergoes regular reflection at the supporting surface 8a. The wave is propagated along the incident path in the reverse direction and received in the probe 4 as the reflected wave from the member 8.

摘要： PURPOSE:To accurately detect the deterioration of turbine parts, by correcting the ultrasonic echo, which is reflected from the damage region of turbine parts and returned to a probe, with a prepared measured value and judging whether the correction value exceeds a reference value. CONSTITUTION:The shower wave and flaw echo, which enter the creep damage region in a turbine from an ultrasonic probe 11 and reflected therefrom to be returned to said probe, are observed. A hardness meter 12 measures the surface hardness of turbine parts and inputs the result thereof to an operation circuit 13. An operation circuit 13 corrects the echo detected by the probe 11 on the basis of the measured value detected by the hardness meter 12 to judge whether the correction value exceeds a reference value and the presence of the deterioration of turbine parts is judged.

摘要： PROBLEM TO BE SOLVED: To provide a measuring method and measuring device for a cross sectional structure of a tire capable of automatically and rapidly measuring the cross sectional structure of the tire. SOLUTION: In this device, linear scanning tracks 5, 6 installed with mechanisms capable of linearly and circularly moving displacement measurement sensors or the like attached to their tips are fixed to a ring-like outer face scanning track 4 capable of opening and closing with one point as the center. The outer face scanning track 4 fixedly provided with the linear scanning tracks 5, 6 is horizontally and vertically movably mounted and held on a measuring device frame structure 3. A data processing/controlling unit 7 processes data detected by the respective sensors and controls operation of the mechanisms on the basis of the processed data. A tire 1 to be measured is positioned inside the ring-like outer face scanning track 4. Then, a shape in a cross section perpendicular to the circumferential direction of the tire 1, or a position or distribution of structure material inside the cross section is measured according to the control of the data processing/controlling unit 7.

摘要： PROBLEM TO BE SOLVED: To perform accurate eddy current flaw detection on sections such as a weld with magnetic anisotropy. SOLUTION: An eddy current flaw detecting device subjects a detection region of metal to be inspected with magnetic anisotropy to the action of a magnetic field in advance and performs eddy current flaw detection on the detection region as suppressing fluctuations of magnetic permeability in the detection region. The flaw detecting probe 40 of the device comprises a permanent magnet 41 to subject the detection region to a magnetic field, an electric motor 43 to change the direction of the acting magnetic field, a detecting coil 11 to detect the change of eddy current due to a defect in the detection region as the change of its impedance and is connected to a flaw detector to output and display the changes in the impedance of the detecting coil 11.

摘要： PROBLEM TO BE SOLVED: To detect a microflaw signal accurately by converting a signal amplified through a preamplifier into a digital signal, adding a correction code thereto, and encoding the signal through an encoding circuit thereby suppressing the effect of attenuation and noise on the flaw signal during transmission. SOLUTION: An analog signal from a preamplifier 11 is converted through an A/D converter 12 into a digital signal. It is then added with an error correction code and encoded through an encoder circuit 13 and the output signal is received by an eddy current flaw detector 4 while being buffered through a butter IC 14. When a flaw is present in a body to be tested, a detection coil 1 in an eddy current flaw detection probe detects variation in the field. A flaw signal is amplified through an amplifier 11, converted through an A/D converter 12 and delivered to the encoder circuit 13. The encoder circuit 13 adds an error correction signal to the digital signal and delivers the added signal from the butter IC 14 to the eddy current flaw detector 4 thus correcting error of the signal due to noise.

摘要： PROBLEM TO BE SOLVED: To save labour of measuring staffs and reduce production cost of a device in a measurement of an oil surface level in an oil tank. SOLUTION: A transmitting/receiving electrode 3 having antennas 1 on the both ends of a piezoelectric substrate 2 and an alarm signal reflecting electrode 5 are provided and arranged in a prescribed position in an oil tank. When an external device 34 transmits an electric signal to the transmitting/receiving electrode 3 via the antennas 1, the transmitting/receiving electrode 3 excites a surface elastic wave 29. The surface elastic wave 29 is transmitted to the piezoelectric substrate 2, reflects on an oil surface 28, and returns to the transmitting/receiving electrode 3 again. The transmitting/receiving electrode 3 receives the surface elastic wave 29 so as to transmit the electric signal and sends to the external device 34 via the antenna. The external device 34 measures the time from transmitting the electric signal to receiving the electric signal again, the distance between the transmitting/receiving electrode 3 and the oil surface 28 is measured so as to find the oil surface level. When the surface elastic wave 29 is reflected by an alarm signal reflection electrode 5, the external device 34 informs that the oil quantity is extremely a little.
