摘要： PROBLEM TO BE SOLVED: To provide a magnet which has both superior electric resistance and magnetic characteristics. SOLUTION: The magnet molding includes magnet powder, magnetic particulates having a smaller average particle size than the magnet powder, and an insulating coating covering the magnet powder and magnetic particulates, the magnetic particulates being present at least partially between the magnet powder and insulating coating. Further, the magnet molding has a reaction layer formed of the magnetic particulates and insulating coating. Furthermore, the magnetic particulates are a ground product of the same material with the magnet powder. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a magnetostrictive stress sensor which is excellent in an installing property to a detection target and detection sensitivity, compact and easy to be handled, and inexpensive and excellent in robustness, by putting a stress sensor using an opposite effect of magnetostriction to practical use. SOLUTION: A shaft-shaped magnetic body 1 having magnetostriction and equipped with a hollow portion 1a at a shaft core portion is magnetized in a circumferential direction to make a stress detecting portion 2. The stress detecting portion 2 is provided with a detection head 10 having a platy permanent magnet 11, magnetic sensors 12 and 13, and a platy yoke 14. Those sensors, magnet, and yoke are arranged at predetermined positions. The changes of a magnetic flux flowing outside the magnetic body when stress acts on the magnetic body 1, out of a magnetic flux generated from the permanent magnet 11 and distributed into a magnetic flux passing through the inside of the magnetic body 1 and flowing outside the magnetic body 1, is detected to detect axial stress acting on the magnetic body 1.
