摘要： A sensor includes a first element part having a first member and a first element. The first member is a acoustic tubular waveguide and extends along a first direction. The acoustic tubular waveguide includes a first opening and a second opening. A direction from the second opening toward the first opening is along the first direction. The first element includes a vibratile first membrane, and a first supporter supporting the first membrane. The second opening is between the first opening and the first membrane in the first direction. The sensor may be a Piezoelectric Micro electro mechanical systems Ultrasonic Transducer and may be used for inspecting paper and/or resin including detecting thickness of a fed through banknote and/or the presence of foreign matter thereon such as tape. An optical element may alternatively measure the vibration of a membrane from acoustic through transmission instead of an acoustic receiver.

摘要： The embodiments provide a high-performance permanent magnet. The permanent magnet includes a sintered body having a composition expressed by a composition formula RpFeqMrCutCo100-p-q-r-t, with carbon in a range from 50 mass ppm to 1500 mass ppm. The sintered body also includes a metallic structure. The metallic structure includes a main phase having a Th2Zn17 crystal phase, and a secondary phase having a carbide phase of the M element of the composition formula. A ratio (I2/I1) of a maximum intensity I2 of a diffraction peak at an angle 2θ in a range from 37.5 degrees to 38.5 degrees to a maximum intensity I1 of a diffraction peak at the angle 2θ in a range from 32.5 degrees to 33.5 degrees is greater than 25 but no greater than 80 in an X-ray diffraction pattern obtained by applying an X-ray diffraction measuring method to the sintered body.
