Abstract: An iron core (1, 11, 31) for a stationary induction apparatus according to one embodiment is configured by laminating a plurality of electromagnetic steel plates (5, 16, 33). The electromagnetic steel plates are laminated so that joint parts (6, 17, 18, 32), at which the end portions of the electromagnetic steel plates abut one another, are disposed in a staggered manner; and the electromagnetic steel plates are provided with a magnetic domain fine differentiation processed part (7, 19, 34), which is located on the portion, of a surface of the end portion of each of the electromagnetic steel plates, lapped with the joint part of another electromagnetic steel plate, and which has been subjected to warping-derived magnetic domain fine differentiation.

Abstract: Provided is a stator core formed by laminating electrical steel sheets to steadily curtail iron loss and a motor equipped with the stator core. A stator core 10 formed by laminating electrical steel sheets 11 having a thickness of from 25 to 80 ?m steadily curtails iron loss. A motor 20 including the stator core 10 formed by laminating electrical steel sheets 11 having a thickness of from 25 to 80 ?m has a steadily improved efficiency.

Abstract: A vector-magnetic-property-controlling material according to the present embodiment is subjected to a scratching process in two directions that intersect on the surface of a steel material. An iron core according to the present embodiment is configured from an oriented magnetic steel material which has been subjected to a scratching process in two directions that intersect on the surface thereof.

Abstract: A load body state is judged from time series data of an emphasis displacement inclination obtained by collecting displacement signal data of the load body state using a displacement signal collection sensor, determining a rate of change for every arbitrary interval of an original waveform as an original waveform displacement inclination at an operating unit, and at the same time, determining time series data of an average displacement inclination for every prescribed time period range from a plurality of original waveform displacement inclinations, and by determining an emphasis displacement inclination through slide calculation of time series data of the average displacement inclination for every prescribed sampling time.

Abstract: The present invention makes it possible to easily perform judgment of a mental-and-physical state, and distinction between a person and a thing. A load body state is judged from time series data of an emphasis displacement inclination obtained by collecting displacement signal data of the load body state using a displacement signal collection sensor 10, determining a rate of change for every arbitrary interval of an original waveform as an original waveform displacement inclination at an operating unit 20, and at the same time, determining time series data of an average displacement inclination for every prescribed time period range from a plurality of original waveform displacement inclinations, and by determining an emphasis displacement inclination through slide calculation of time series data of the average displacement inclination for every prescribed sampling time.

Abstract: A magnetic circuit includes a multi-pole magnet mounted on a predetermined surface of a yoke and having magnetic poles formed in a direction perpendicular to the predetermined surface of the yoke. The multi-pole magnet is separated into two pieces, and a single-pole magnet is interposed between the two pieces of the multi-pole magnet. Magnetic poles of the single-pole magnet are formed in a direction different from the direction in which those of the multi-pole magnet are formed.

Abstract: In circular conductor plates having radial slits alternately stacked with spirally wound coils continuously connected in order and supplied with comparatively low frequency AC current, eddy currents generated in peripheral direction are concentrated along the radial slits around central holes of the conductor plates, so as to induce concentrated AC magnetic fluxes in those holes. As a result, an intense AC magnetic field can be efficiently obtained by a comparatively small driving AC current in comparatively low frequency range.
