Abstract: A magnetic member includes a plurality of superparamagnetic particles held by the magnetic member. Each of the plurality of superparamagnetic particles is formed with a particle size which is set at least such that a Neel relaxation time ?n in the each of the superparamagnetic particles becomes shorter than a cycle P of an alternating current magnetic field applied to the magnetic member (?n<P) when the magnetic member is used as an electronic component.

Abstract: A current sensor according to the present invention includes a sensor element and a detector. The sensor element includes a core member, an exciting coil and a detection coil. The sensor element is configured such that, while the exciting coil is fed with an excitation signal, comprising a fundamental component, and when the signal to be detected flows, a signal, including a harmonic component, corresponding to the permeability ? of the core member at that point, being superposed on the fundamental component, is outputted from the detection coil. The detector includes a component extraction unit, a level specification unit, and an information output unit.

Abstract: The method of and apparatus for producing fluid dynamic bearing parts is provided. Sets of grooves are formed by an electrochemical machining apparatus based on a design specification. The electrochemical machining process includes a process for extracting one bearing part in every predetermined number of machining cycles during the bearing parts production, a process for measuring shapes of the grooves on the extracted bearing part, a process for comparing the shapes of the grooves on the extracted bearing part with the design specification data, and a process for changing settings of the electrochemical machining apparatus depending on the result of the comparison. With these processes a stable and precise production of grooves on the fluid dynamic bearing parts are possible during mass production.
