摘要： A rotary eddy current flaw detection probe device has a plurality of Θ-shaped eddy current flaw detection probes attached in a rotating disc for detecting flaws in all directions regardless of the flaw direction. Four Θ-shaped eddy current testing probes P11 to P22 are arranged around the rotation center Ds1 of a rotating disc 111 and are embedded in the disc 111. The coil planes of detector coils Ds11 to Ds22 of the testing probes P11 to P22 are parallel with each other, and are perpendicular to the rotation plane of the rotating disc 111. The coil planes of the detector coils incline at an angle θ relative to a line Y passing through the centers Ps11 and Ps12 of the probes P11 and P12. The detector coils Dc11 and Dc12 are cumulatively connected to each other and the detector coils Dc21 and Dc22 are differentially connected to each other.

摘要： A portable air blower includes: a first pipe having a first outlet opening communicating with a main body, the first pipe discharging wind generated in the main body through the first outlet opening; and a second pipe having a larger diameter than that of the first pipe, the second pipe being attached movably in the axial direction to the outer circumference of the first pipe and having a second outlet opening having a larger diameter than that of the first outlet opening. In the portable air blower, the second pipe is moved relative to the first pipe to dispose the second outlet opening upstream or downstream of the first outlet opening; the second pipe has an inflow window disposed upstream of the first outlet opening, the inflow window enabling air to flow from the outside into the second pipe.
