摘要： PROBLEM TO BE SOLVED: To provide a dynamic sensor of small type and with high sensitivity superior in impact resistance, and temperature characteristics which uses a magnetic thin film.
SOLUTION: The dynamic sensor for sensing external force comprises a nonmagnetic substrate 10 capable of elastic deformation following the external force, and the magnetic thin film 12 which is formed on the nonmagnetic substrate 10 and is provided with a plurality of parallel line parts and folded back by electrically serial connection, and the direction of easy magnetization axis is perpendicular to the longitudinal direction of the line parts, and imparted with magnetic anisotropy. The magnetic thin film 12 is formed on the substrate, in such a way that the longitudinal direction of the line parts, the direction of the easy magnetization axis and the direction of the impressed external force are mutually orthogonal. The electrical signal is obtained, by making high-frequency current flow from both the ends of the magnetic thin film, and the change of impedance generated between both the ends is transduced into the output electrical signal.

摘要： PURPOSE:To miniaturize this magnetic circuit by arranging plural yokes outside the magnetostrictive pulse generating element at intervals and coupling their one-terminal sides with the element, and arranging a permanent magnet which applies a magnetic field to one of them at the other end of the element. CONSTITUTION:The magnetostrictive pulse generating element (WIEGAND element) 10 is provided between 1st and 2nd yokes 21 and 22, which are arranged in parallel at a specific interval and have one-end sides coupled mutually, in parallel and their one-end sides are coupled with the coupling parts of the yokes 21 and 22. At the other-end sides, the permanent magnet 1 is supported in an up-down movable state. When the magnet 1 is moved and its N pole approaches the yoke 21, a magnetic path is formed while penetrating the yoke and element 10, and the magnetization direction of the internal core part 11 is inverted abruptly to induce a voltage pulses in a detection coil 13. When the S pole of the magnet 1 approaches the yoke 22, on the other hand, the magnetization direction of the internal core part 11 is re-inverted abruptly to induce a reverse-directional pulse. Consequently, only one permanent magnet 1 is required and the circuit is reduced in cost and size; and displacement/output characteristic setting with an external force is facilitated and the degree of freedom can be increased.

摘要： PURPOSE:To obtain a meter having high general-purpose applications, by turning and moving a U-shaped moving body with respect to a magnetostrictive wire, which is formed in a circular shape and wound by a plurality of turns, and providing a signal generating part and detecting part at one end of the magnetostrictive wire and the moving body. CONSTITUTION:A U-shaped moving body 60 is provided so as to hold a magnetostrictive wire 40, which is wound by a plurality of turns in a circular shape. The moving body 60 is turned and moved relatively with respect to the magnetostrictive wire. An ultrasonic-wave signal generating part 90 and detecting part 100 are provided at one end of the magnetostrictive wire 40 and the moving body, respectively. When a driving coil 91 is energized, local change in magnetic field occurs at an end part 41 of the magnetostriction line 40. The change is converted into longitudinal elastic waves by the magnetostriction effect, and the waves move to the detecting part 100. Meanwhile, in the detecting part 100, magnetic flux generated in a permanent magnet 103 forms a closed magnetic path. When a magnetostriction signals enters said magnetic path through the magnetostrictive wire 40, the permeance of the magnetic path is changed by the reverse magnetostriction effect. As a result, a pulse voltage, which has a delay time corresponding to the displaced position of the detecting part, is generated in a detecting coil 104.
