Abstract: A geared motor includes a synchronous reluctance motor whose maximum rotational speed is 20000 rpm to 45000 rpm and in which rare earth bonded magnets are embedded in a rotor, and a speed reducer which reduces the rotational speed of the synchronous reluctance motor to a rotational speed in a usage range while increasing torque to a predetermined range. When a radius of the rotor is represented by R (cm) and a length of the rotor in an axial direction is represented by L (cm), the rotor has a size which satisfies conditions of 2 cm?R?6 cm and 2 cm?L?25 cm.

Abstract: An electric motor for reducing eddy current loss including an armature; a field element or permanent magnet as a magnetic source; and a shaft rotating together with the armature or field element. The permanent includes magnet particles bound together by a binder resin, and has a degree of electric resistance anisotropy (?1/?2) of 2 or more. The first electric resistivity (?1) is measured in an axial direction and a second electric resistivity (?2) is measured in a direction perpendicular to the axial direction. The bonded magnet is, for example, a compression-molded bonded magnet that contains 93% to 98.5% of the magnet particles, and the first electric resistivity is 300 ??m or more. When the compression-molded bonded magnet whose compression direction is arranged along the axial direction is used as a field source, the eddy current loss occurring in the compression-molded bonded magnet can be efficiently reduced.

Abstract: The present invention relates to a method for producing a rare earth anisotropic bond magnet containing a hollow cylindrically shaped magnetic molded body having, at the hollow cylindrically shaped side face thereof, at least 4 or more orientation portions that are oriented with semi-radial distribution by compression molding of a magnetic material after thermally orienting step, wherein intermediate aligning magnetic fields applied in the thermally orienting step to between adjacent cavities are the mostly same in their magnetic directions. A plurality of rare earth anisotropic bond magnets can be efficiently produced at one time.

Abstract: The aim of the present invention is to offer a keeper for a dental magnetic attachment that is strong, has low manufacturing costs, and is not easily detached from the tooth root. The keeper proposed herein has a keeper body, which is shaped like a plate, and a root, which is attached to the bottom of the keeper body. The keeper body and the root are machined from a single piece of soft magnetic material in one piece. The root has a smaller diameter part that is linked to a larger diameter part whose external diameter is larger than an external diameter of the smaller diameter part. The smaller diameter part is linked to the bottom of the keeper. There are multiple circumferential grooves around the outer side of the larger diameter part.

Abstract: A magnetic apparatus for detecting a position of a vehicle, capable of detecting a lateral deviating distance of a vehicle over a lateral deviation width with a high accuracy and at a high speed, wherein a magnetic field component in the direction of advance of the vehicle is detected; or more preferably a three dimensional magnetic sensor (1), which comprises a magnetic sensor element for the direction of advance of the vehicle, and magnetic sensor elements for two directions crossing the first-mentioned direction and provided additionally, is used, whereby it becomes possible to heighten a center retaining capability of the vehicle, widen a lateral deviating distance detecting range around four times from around 25 cm to around 1 m, and detect a magnetic marker (3) reliably even when disturbance magnetic field exerts influence upon this detection operation to thereby start center side guidance reliably.

Abstract: A denture attachment including a magnet body, to be embedded in a denture base, comprises a pair of soft magnetic alloy end plates, a non-magnetic alloy spacer disposed between the end plates, and a cap covering the magnet body, the end plates and the spacer except on the side of a coping. The attachment causes a magnetic attractive force of the magnet body to act on the coping of a soft magnetic alloy embedded in a pulp cavity of a tooth deprived of the crown, whereby the denture base is stabilized on gingiva. The magnet body is disposed with its N and S poles facing the end plates, respectively.
