摘要： A hollow cylindrically shaped anisotropic bonded magnet for use in a 4-pole motor, is 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： The rectifying characteristic of a brush-equipped direct current machine is improved, and the life of the machine is extended.As illustrated in FIG. 2, a magnetic flux density reduced portion in which the magnetic flux density is reduced is formed in a magnetic pole section of an anisotropic bonded magnet. The position in the magnetic pole section formed with the magnetic flux density reduced portion is formed at the position at which, when a rectifier coil moves in a rectification section, the absolute value of the density of a magnetic flux penetrating the rectifier coil is increased due to the influence of the magnetic flux density reduced portion. Thus, an inverse voltage can be induced in the rectifier coil in the direction of inversion current during a rectification period. It is therefore possible to facilitate the inversion of the current, and to compensate for inadequate rectification and improve the rectifying characteristic. Accordingly, the occurrence of sparks at the end of the rectification can be prevented.

摘要： The challenge to be solved by the present invention is the miniaturization of a 1-300 W class of motor. This can be achieved by using a hollow-cylinder shaped anisotropic bonded magnet magnetized in a 4-pole configuration. The anisotropic bonded magnet has a maximum energy product approximately 4 times greater than the conventional sintered ferrite magnets. The use of a 4-pole configuration shortens the magnetic path length of the individual magnetic circuits and the magnetic force contributing to the torque is increased. When the torque is kept the same as in the conventional motor, the length of the electromagnetic rotor core and the axial magnet length can be reduced. In this fashion, 1-300 W class motors can be reduced in size.

摘要： The bonded magnet of the present invention, in which average particle diameter and compounding ratio are specified, is comprised of R1FeB coarse powder that has been surface coated with surfactant, R2Fe(N, B) fine powder that has been surface coated with surfactant (R1 and R2 are rare-earth elements), and a resin which is a binder. Because the outside of R1FeB coarse powder is enveloped by resin in which R2Fe(N, B) fine powder is evenly dispersed, the R2Fe(N, B) fine powder and resin become a cushion and the R1FeB coarse powder does not deteriorate. As a result, the R1FeB coarse powder exhibits intrinsically excellent magnetic properties, and a bonded magnet with excellent magnetic properties and permanent flux loss ratio is obtained.

摘要： A production method to produce an anisotropic NdFeB based alloy magnet having a high anisotropic ratio and coercivity by a simple procedure. The production method consists of a first hydrogenation process, a second hydrogenation process and a desorption process. The first hydrogenation process at a low temperature produces the hydride that stores hydrogen needed in advance of the phase transformation. After that, the second hydrogenation process at an elevated temperature proceeds smoothly at a moderate reaction rate of the phase transformation and produces the mixture of NdH2, Fe and Fe2 B from the hydride in addition to making the crystallographic orientation of Fe2 B phase consistent with the original R2 Fe14 B matrix phase. Subsequently, the desorption process produces the fine grained microstructure of Nd2 Fe14 BHx with high degrees of alignment of the crystallographic orientation consistent with the original crystallographic orientation of Fe2 B phase. Fine and uniform grained microstructure of RFeB based alloy is produced by recombination of the mixture during the hydrogen heat treatment and consequently offers the anisotropic rare earth magnet powder to have a high anisotropic ratio and high coercivity.

摘要： A dental magnetic attachment having good cushioning properties against a compressing pressure which makes a denture sink appropriately on biting. The dental magnetic attachment embedded in the denture base for holding the denture in the oral cavity by a magnetic attractive force working with the magnetic assembly and a soft magnetic keeper embedded in the top of the root surface includes a magnetic assembly and a cap covering the top of the magnetic assembly. The magnetic assembly has a hollow in the center of its top. The cap with a button is placed on the magnetic assembly, inserting the button into the hollow to contact to its bottom. On biting, the button is compressed, to be deformed with a shorter thickness and at this time a sleeve formed as a body around the core slides down along the side of the magnetic assembly to reduce the thickness of the dental magnetic attachment. This sliding makes the denture sink uniformly and appropriately. The dental magnetic attachment has good cushioning properties and offers a good feeling to a patient when biting with the denture.
