Magnetic detector

A magnetic detection device that is reduced in size and thickness, but also accurate, includes a substrate and an element disposed on the substrate and including a magneto-sensitive wire sensing an external magnetic field component in an extending direction and a detection coil looping around the magneto-sensitive wire. The magnetic detection device further includes a magnetic field deflector deflecting an external magnetic field around the magneto-sensitive wire, and having a nonmagnetic material core part and a soft magnetic material shell part covering an outer side of at least part of the core part. ...

Magneto-sensitive wire for magnetic impedance sensor capable of high-accuracy measurement and method of manufacturing same

A magneto-sensitive wire for a magnetic impedance sensor and a method of manufacturing the same are provided which can prevent generation of abnormal noise in an output voltage and deterioration in hysteresis characteristics and enable higher-accuracy measurement than conventional magneto-sensitive wires. The magneto-sensitive wire (1) comprises an amorphous wire for detecting magnetism. ... Aichi Steel Corporation

Ball rotational direction detecting system

A ball rotational direction detecting system includes a magnetic sensor that is fixed in a ball, an acceleration sensor, a bearing recording unit that records a moving bearing, a magnetic dip recording unit that records a magnetic dip α of geomagnetism, and a calculating unit. The calculating unit calculates the orientation of the rotation axis and the rotational direction of the ball with respect to a traveling direction f and a gravity direction g of the ball, based on a geomagnetism vector m, an acceleration vector a, the moving bearing, the magnetic dip α, and time variations in the geomagnetism vector m or the acceleration vector a.. ...

Magnetic field measurement device

A magnetic field measurement device capable of accurate measurement of a magnetic field even after a sensitivity of an mi sensor varies is provided. A magnetic field measurement device (1) includes an mi sensor (2) and a sensitivity calculation means (3). ... Aichi Steel Corporation

Production method for anisotropic bonded magnet and production apparatus for same

A production method for an anisotropic bonded magnet includes: filling the annular cavity with a magnet raw material including one or more types of rare-earth anisotropic magnet powder and a binder resin; applying aligning magnetic fields to the magnet raw material being aligned in the softened or molten binder resin, the aligning magnetic fields are applied from an even number of aligning magnetic pole bodies arranged around outer periphery of the annular cavity such that directions of magnetic fields are alternated; subjecting the magnet raw material to a molding to form a compact; rotating the aligning magnetic pole bodies in circumferential direction for a predetermined angle; and applying demagnetization magnetic fields to the compact from the aligning magnetic pole bodies during the alignment step. The demagnetization magnetic fields are in directions for cancelling magnetization of the compact caused by the aligning magnetic fields.. ... Aichi Steel Corporation

Anisotropic rare earch magnet powder, method for producing the same, and bonded magnet

Anisotropic rare earth magnet powder particles include r2tm14b1-type crystals of a tetragonal compound consisting of one or more rare earth element, b, and one or more transition element, and enveloping layers containing at least nd and cu. Surfaces of the r2tm14b1-type crystals are enveloped by the enveloping layers. ... Aichi Steel Corporation

Magnetic detection device and method for manufacturing same

A reduced size/thickness magnetic detection device includes: a substrate; and a magneto-impedance element at one substrate surface side and including a magneto-sensitive wire and a detection coil. The wire senses an external magnetic field component in a first axis direction in which the wire extends. ... Aichi Steel Corporation

Method and apparatus for manufacturing interior permanent magnet-type inner rotor

A manufacturing method for obtaining an interior permanent magnet-type inner rotor without thermal demagnetization due to shrink fitting to a rotating shaft includes: a shrink fitting step of heating a rotor core having slots and inserting a rotating shaft into a shaft hole to shrink-fit the rotor core; and a filling step of filling the rotor core slots in a residual heat state after the shrink fitting step with a flowable mixture of a binder resin heated to a flowable state and anisotropic magnet particles, in oriented magnetic fields this allows, in similar manufacturing steps, an inner rotor of which the magnetic poles are anisotropic bond magnets formed by solidifying the flowable mixture in the slots and a conventional inner rotor of which the magnetic poles are sintered magnets. This allows both the inner rotors concurrently and in parallel (mixed flow production) in an already existing ipm motor manufacturing line.. ... Aichi Steel Corporation

Rotation speed measuring system

A rotation speed measuring system includes a magnetic sensor, an acceleration sensor, an end detecting unit, and a calculating unit. The magnetic sensor measures earth magnetism in at least one axis direction. ... Aichi Steel Corporation
