摘要： PROBLEM TO BE SOLVED: To automatically and accurately measure the thickness of the tubular body which are sectioned in a regularly polygonal shape including the R parts of the corners. SOLUTION: An ultrasonic wave probe 2 sends an ultrasonic wave from its reverse surface and detects the time difference between an ultrasonic wave reflected by the top surface 1A of a body 1 to be measured to return and an ultrasonic wave which reflected by an internal surface 1B after being transmitted through the top surface 1A to return to measure the thickness (d) of the body 1 to be measured. An ultrasonic wave probe elevating mechanism 3 moves the ultrasonic wave probe 2 vertically. An ultrasonic wave probe rotating mechanism 4 rotates the ultrasonic wave probe 2 at a specific angle and stops it at an arbitrary angle position. A measured body rotating mechanism 5 rotates the body 1 to be measured. An ultrasonic wave probe horizontal moving mechanism 6 moves the ultrasonic wave probe 2 over the horizontal movement range of the overall length of the body 1 to be measured and stops it at an arbitrary position.

摘要： PROBLEM TO BE SOLVED: To prevent direct contact with a user's skin so as to improve a seat belt wearing rate by arranging a human body contact piece having a soft touch on a back face of a main body, which can be closed with a seat belt clamped from the front and back sides, and arranging an attaching member, to/from which a desired member can be freely attached/detached, on the front face. SOLUTION: A main body 1 made of a plastic double-folded plate can be freely opened/closed while using a crease 2 as a hinge. A human body contact piece 3 made of urethane fabric having a soft touch is arranged on the back face of the main body 1. On the other hand, an attaching member 4, to/from which a desired member 10 can be attached/detached freely, is arranged on the front face of the main body 1. The attaching member 4 cooperates with an attaching member 14 for fixing the desired member 10 on the front face of the main body 1. In this process, both of the attaching members 4, 14 are formed by using velvet fasteners and constructed of male and female locking members individually. In an adapter, a seat belt B is positioned on the inside while the main body 1 is opened, and then, the adapter is closed and fixed with the seat belt clamped by the locking means (attaching members 4, 14).

摘要： PURPOSE:To make possible the magnetic powder method of high flaw detection force and high reliability of a steel tube inside face by magnetizing on alternating current an interior coil composed of an shaft body inserted in the inner face of the steel tube and a coil lead wire wound around the shaft body. CONSTITUTION:An interior coil 2 consists of a shaft body 11 inserted along the direction of a tube axis in the inner face of the end of a steel tube 1 and a coil lead wire 10 wound around it. The shaft body 11 is formed to overlap a plurality of silicon steel plates. Parallel crosses twin coils 7 are disposed at the specified positions of its circumference on the end of the tube 1 and the coil 2 is inserted. When alternating current is allow to flow in the coil 2 from an alternating power source 8, a magnetic flux is given to the tube 1 through the shaft body 11, and when three-phase alternating current is allowed to flow in the coil 7 from a three-phase power source 9, a rotating magnetic field is generated. As a result, a vertical magnetic field and a horizontal magnetic field are generated in the outer surface and the inner surface of the end of the tube 1 and the end of the tube 1 is stably magnetized over the all directions of the inner and outer surfaces. The much magnetic flux exists in the inner face of the tube 1 because the magnetic field passes a low electric resistance part by means of the coil 2, and detection force of the inner face is improved.

摘要： PURPOSE:To improve the accuracy of detection by insertig a copper pipe which has a slit part and incorporates an iron core into a steel pipe placed between two series coils in the same direction, feeding a rectified wave current to electrode plates at both ends, and supplying an alternating current to the coils. CONSTITUTION:The two coils 4 and 4' connected in series in the same winding direction are added to both ends of the steel tube 1 to be inspected, and the copper pipe 2 which has the slit part 2a bored axially and incorporates the iron core 3 is inserted. Then, the alternating current is flowed to the coils 4, 4' to supply alternating magnetic flux to the iron core 3, and the material 1 to be insepcted is magnetized with an induced current to detect a circumferential defect. Further, the electrode plates 5, 5' are brought into press contact with both end parts of the copper pipe 2 and a single-phase half-wave rectified current is fed from the same three-phase AC power source with the coils to detect an axial defect of the material 1 to be inspected. Consequently, defects in the inside of the material 1 to be inspected in all directions are detected at the same time speedily and accurately.

摘要： PROBLEM TO BE SOLVED: To reuse the processing water by adding an additive to any one of penetrant water or cleaning waste water thereby accelerating aggregation and separation of penetrant liquid in the cleaning waste water. SOLUTION: A cationic, anionic or nonionic polymer or a surfactant is employed as an additive. The polymer is principally added to cleaning waste water by 0.1-1000 ppm or less while the surfactant is added principally to penetrant liquid by 0.01-3% and both of which accelerate adhesion, condensation, aggregation and separation of dispersed penetrant liquid due to neutralization of charges. The penetrant liquid is a hydrophobic penetrant liquid and prepared by adding several kinds of dilution solvent and a red dye or a fluorescent dye to a several kinds of petroleum based solvent satisfying the basic conditions of penetration, viscosity, and the like. According to the arrangement, condensation and aggregation of penetrant liquid in the cleaning waste water are accelerated, the penetrant liquid is separated easily from the water and the processing can be reused.
