摘要： PROBLEM TO BE SOLVED: To provide a device for specifying positional information, enabling an image pickup device to easily read correct positional information of each of positions in a three-dimensional space.
SOLUTION: In this device for specifying positional information device 1, a plurality of laser beam irradiating means 5 each capable of moving the irradiation direction of a laser beam with a universal joint are disposed on the peripheral surface of a casing 3. Consequently, since the laser beam has an exposure point S having a luminance higher than that of surroundings, the distance from to the point S can also be measured with high accuracy, even if the distance is measured by automatic focus detecting method.

摘要： PROBLEM TO BE SOLVED: To learn not only the position of a worn part of an object to be inspected but also the volume thereof. SOLUTION: A roughly long-sized object 1 to be inspected and a test piece with the shape thereof the same as the object while being set to a specified volume of a worn part are prepared. An ultrasonic wave is admitted into the object 1 and the test piece respectively from each one end thereof and a bottom surface echo B of the ultrasonic wave reflected at the other end of the object or the test piece and subsequent delay echoes Wa, Wb and Wc converted in mode are measured at the one end of the object or the test piece. Comparison is made between the relative attenuations in the amplitude of the delay echoes as respectively obtained from the results of the object and the test piece when the amplitude of the bottom surface echo is used as reference to determine the volume of the worn part of the object.

摘要： PROBLEM TO BE SOLVED: To automatically supply rock wool in equipment forming a refractory coating material. SOLUTION: A control apparatus 48 starts a feed means 8 when the height of the rock wool material housed in a hopper 10 is lower than a predetermined height as a result of the detection by a level sensor 43. The started feed means 8 presses wool laminate 6 on a slipping table 4 toward the end part 22 of the slipping table 4 by a pusher 18 to move the same and, as a result, the head compressed rock wool material 16 falls on the slipping table 4 to be charged in the hopper 10. When the compressed rock wool material 16 falls from the slipping table 4, a falling sensor 41 detects the falling compressed rock wool material 16 and the control apparatus 48 allows the feed means 8 to stop the laminate 16. That is, when the rock wool material in the hopper 10 is reduced, the new compressed rock wool material 16 is automatically supplied by the slipping table 4.

摘要： PURPOSE: To enhance accuracy by subjecting signals obtained by the ultrasonic inspection of a nondefective welded piece and an object for inspection to Fourier transform for the purpose of calculating their frequency components, and multiplying the frequency component of the object for inspection by the corresponding frequency component of the nondefective welded piece for the correction of the components, and a calculating the proper inspection signal through inverse Fourier transform. CONSTITUTION: A welded piece 1 of austenite stainless steel is butt welded, and it is made sure beforehand that the welded part 1a has no defects. A longitudinal-wave-transmitting angle probe 2 and a receiving probe 3 are used to pass beam through the welded portion 1a, and an inspection signal is subjected to Fourier transform so as to calculate its frequency components. Next, the welded portion 5a of an object 5 to be inspected which is made from the same material and formed by the same method as the welded piece 1 is inspected by pulse reflection method by means of a longitudinal-wave-receiving angle probe 7, and an inspection signal is subjected to Fourier transform to detect its frequency components. Correction factors are calculated from frequency components detected by the previous inspection and are multiplied by the corresponding frequency component of the object 5 to be inspected, and the results are subjected to inverse Fourier transform so that a corrected inspection signal can be obtained.

摘要： PURPOSE:To determine the appropriateness of the layer thickness of a contact medium. CONSTITUTION:Reflected wave signals based on reflected waves of an ultrasonic wave on the surface of a contact medium 20 and the surface of a material 10 to be inspected are outputted from a gate part 551. Comparing parts 552 and 553 compare the reflected wave signals with a positive reference voltage and a negative reference value set beforehand and output signals respectively in the case when the reflected wave signals are larger than the positive reference voltage and in the case when they are smaller than the negative reference voltage. A flip-flop 555 is set when the comparing part 552 outputs the signal earlier than the comparing part 553, while a flip-flop 557 is set when the comparing part 553 outputs the signal earlier than the comparing part 552.

摘要： PROBLEM TO BE SOLVED: To predict the remaining service life of pipe with high accuracy in a short time by comparing the relative amount of carbide taken from a subject and the lattice constant thereof with the relative amount of carbide taken preliminarily from a material used for a long time and the lattice constant thereof, and observing the micro texture. SOLUTION: A ultrasonic wall thickness measurement is applied to a Cr-Mo steel heating furnace pipe being a subject. When the pipe is corroded after the surface thereof is ground and mirror finish polished, a replica of the micro texture in the pipe is formed. Carbide is extracted from the ground powder generated at the time of grinding the pipe, and then an analysis of X-ray diffraction is applied thereto. The ground powder is dissolved with phosphate, and the solution is filtered by a filter to collect the remainder, and then the content of the remainder and the lattice constant is measured while the identification of the remainder is made, and also the relative amount is measured. Thereafter, it is determined whether the subject is in a range of experience to which a remaining service life determination method can be applied, or not. Then, the ovservation of micro texture of replica and the comparison with data obtained formerly are carried out, and the relative amount of carbide and the lattice constant are compared with those taken preliminarily from the material used for a long time. Accordingly, degrading can be estimated.
