摘要： In a method of fabricating an R--Fe--B based alloy magnetic powder excellent in magnetic anisotropy, and an R--Fe--B--Co based alloy magnetic powder excellent in magnetic anisotropy and temperature characteristic an R--Fe--B based alloy is subjected to hydrogenation under pressurized hydrogen gas and to dehydrogenation. Excellent magnetic properties and stable with less variation in range can be attained in an industrial fabrication by using a plurality of divided reaction tubes. Moreover, the R--Fe--B--Co based alloy magnetic powder is constituted of an aggregate structure including, as a main phase, a recrystallized structure of an extremely fine R.sub.2 Fe.sub.14 B type phase with an average grain size of 0.05 to 3 .mu.m, and has excellent magnetic anisotropy and temperature characteristic. Additionally, a resin bonded magnet excellent in magnetic properties and temperature characteristic is fabricated by injection molding or compression molding using the above R--Fe--B--Co based alloy magnetic powder.

摘要： To realize an anisotropic bonded magnet that reduces cogging torque without lowering output torque.The present invention provides a hollow cylindrically shaped anisotropic bonded magnet for use in a 4-pole motor, formed by molding anisotropic rare-earth magnet powder with resin. The alignment distribution of the anisotropic rare-earth magnet powder in a cross section perpendicular to the axis of the anisotropic bonded magnet is in the normalized direction of the cylindrical side of the hollow cylindrical shape in the main region of a polar period, and in a transition region in which the direction of the magnetic pole changes, steadily points towards a direction tangential to the periphery of the cylindrical side at points closer to the neutral point of the magnetic pole, and becomes a direction tangential to the periphery of the cylindrical side at that neutral point, and steadily points toward the normalized direction of the cylindrical side at points farther away from the neutral point.

摘要： A motion sensor which can easily and accurately detect bearing, attitude and acceleration in any of three-dimensional directions and a portable telephone using the same. The motion sensor comprises three magnetic sensing parts for detecting magnetic field strength in 3-axis directions orthogonal to one another, and three acceleration sensing parts for detecting accelerations in the 3-axis directions. Each of the acceleration sensing parts has a magnet body constituted to be able to displace depending on acceleration, and a magnet displacement detection head for detecting a displacement of the magnet body. The three magnetic sensing parts and the three magnet displacement detection heads are all made of the same type of magnetic detection elements which operate based on common operation principles. The three magnetic sensing parts and the three acceleration sensing parts are integrated into one modular package together with one electronic circuit for controlling these six magnetic detection elements.

摘要： The present invention provides miniaturization of brushless motors and brush motors used in electric devices, a ring magnet which simultaneously achieves both high torque and a reduction in cogging torque, a ring magnet with yoke, and a brushless motor. The thin hybrid magnetized ring magnet of the present invention is structured of, in a ring magnet comprised of a plurality of magnetic poles, a radially magnetized main pole and an interface for which the interface of the adjoining main pole is polar anisotropic. When the thin hybrid magnetized ring magnet structured in this manner is applied to a brushless motor, in the case of radial magnetizing, the abrupt change in magnetic flux of the interface between the magnetic poles becomes smooth and cogging torque is greatly reduced due to polar anisotropic magnetization of the interface. At the same time, by polar anisotropically magnetizing the interface between the magnetic poles, magnetic flux is concentrated on the radially magnetized main pole, and in comparison to only radial magnetization, maximum surface magnetic flux improves and it is possible to attain high torque.
