摘要： Permeameter suited for measuring permeability of a small, non-magnetic (i.e., the permeability value is close to 1) object. The probe of the permeameter is of the differential transformer type with an exciting coil and two detecting coils placed at both ends of the exciting coil. The difference in the outputs of the detecting coils is analyzed and the effect of the eddy current is effectively eliminated, whereby the signal representing the permeability of the object is extracted from the difference signal by the phase shift analysis. By reducing the distance between the two detecting coils, the influence of the disturbance of the eddy current at the boundary of the object sample is minimized and the permeameter can measure a small object sample without sacrificing accuracy and sensitivity.

摘要： A dental magnetic attachment, which is embedded in the denture base so as to face a soft magnetic keeper 103 and attract the keeper by magnetic force, comprising at least three yokes which are plates and made of soft magnetic material, and at least two pieces of magnet which have the magnetization direction parallel to the thickness. In the example the attachment comprises a central yoke 10, the magnet 1, the magnet 2, the outer yoke 11, and the outer yoke 12. The invention is characterized by a magnet arrangement in which like poles of the magnet 1 and the magnet 2 faces each other. Because of it mutually independent two magnetic circuits are formed and they offer strong attractive force which is two times larger than that of existing ones in a compact volume required for dental attachment. Furthermore, corrosion resistance and wear resistance are improved by covering the attracting face of the magnet 1, 2 with spacers made of non-magnetic material and covering the whole attachment with the cap made of non-magnetic material except the attracting face of the attachment.

摘要： A method for producing an anisotropic rare earth magnet according to the present invention comprises a forming step of obtaining a formed body by press-forming a mixed raw material of a magnet raw material capable of generating R2TM14B1-type crystals of a tetragonal compound of a rare earth element (R), boron (B), and a transition element (TM), and a diffusion raw material to serve as a supply source of at least a rare earth element (R′) and Cu; and a diffusing step of diffusing at least R′ and Cu onto surfaces or into crystal grain boundaries of the R2TM14B1-type crystals by heating the formed body. In this production method, the diffusion raw material having a low melting point and high wettability envelops the R2TM14B1-type crystals, and therefore an anisotropic rare earth magnet having high coercivity can be obtained without decreasing magnetization which should be inherently exhibited by the magnet raw material.

摘要： A magnetic detection device of the present invention includes at least one pair of first magnetosensitive bodies each comprising a soft magnetic material extending in a first axis direction and being sensitive to an external magnetic field oriented in the first axis direction; and a magnetic field direction changer comprising a soft magnetic material and changing an external magnetic field oriented in a different axis direction from the first axis direction into a measurement magnetic field having a component in the first axis direction which can be detected by the at least one pair of first magnetosensitive bodies. With this magnetic detection device, the external magnetic field oriented in the different axis direction can be detected by way of the first magnetosensitive bodies. As a result, while attaining magnetic detection with high accuracy, the magnetic detection device can be reduced in size or thickness by omitting a magnetosensitive body extending long in the different axis direction.
