Abstract: A slide member for use in an automotive vehicle. The slide apparatus includes a first slide member having a slidably contacting surface. Additionally, a second slide member is provided having a slidably contacting surface which is in slidable contact with the slidably contacting surface of the first slide member. In this slide apparatus, at least one of the slidably contacting surfaces of the first and second slide members is formed of a transferable water repellent material having a water repellency and a sufficient transferability to form a transferred film of the transferable water repellent material on at least the other slidably contacting surface.

Abstract: A magnet evaluating device evaluates an evaluation magnet by passing the evaluation magnet, which is formed by connecting a plurality of magnetic sections with insulating material in between, and a master magnet of the same form through an alternating magnetic field generated by an excitation coil, measuring the eddy current occurring in the magnetic section as voltage or current occurring in a detection coil and comparing the measured value for the evaluation magnet and the measured value for the master magnet.

Abstract: A manufacturing device for cleft magnets comprises a cleaving mechanism for cleaving a magnet plate by applying a pressing force to the magnet plate corresponding to a back of a groove formed on one surface of the magnet plate and a carry-in mechanism for carrying the magnet plate to a cleaving position by the cleaving mechanism. By comprising a foreign matter removal mechanism for removing a foreign matter adhering to the magnet plate before the magnet plate is carried to the cleaving position by the carry-in mechanism, the foreign matter adhering to the magnet plate is removed before cleaving.

Abstract: An apparatus for manufacturing magnet segments constituting a field pole magnetic body by cleaving a magnetic body having a coating applied to outer surfaces at a plurality of scheduled cleaving parts includes placing tables on which the magnetic body is to be placed, a pressing unit adapted to cleave the magnetic body by pressing the magnetic body at the scheduled cleaving part arranged between two placing tables, and a cutting unit adapted to cut the coating present at the scheduled cleaving part pressed by the pressing unit after the magnetic body is cleaved.

Abstract: An apparatus for manufacturing a field pole magnetic body formed by laminating magnet segments produced by cutting and dividing a permanent magnet and to be arranged in a rotary electric machine includes a housing part adapted to successively house a plurality of the magnet segments having adhesive applied to cut surfaces with the cut surfaces facing each other and has an inner side surface adjacent to outer side surfaces of the housed magnet segments, and a pressing unit adapted to press the magnet segments housed in the housing part toward a bottom part of the housing part in a longitudinal direction. The magnet segments are restrained in a width direction and a thickness direction by the inner side surface of the housing part when the magnet segments are pressed by the pressing unit.

Abstract: A method of manufacturing a magnet segment of a field pole magnet body includes cleaving a magnet material at a plurality of cleavage target regions arranged with an interval in a longitudinal direction of the magnet material. The cleavage process includes cleaving the magnet material sequentially from the cleavage target region closer to one side edge of the longitudinal direction of the magnet material, wherein a notch is formed in each of the plurality of cleavage target regions of the magnet material such that a depth of the notch closer to the one side edge becomes deeper.

Abstract: A device for manufacturing a field pole magnet body includes a reference jig having reference surfaces in a lengthwise direction, a width direction, and a thickness direction for positioning the plurality of cleaved and divided magnet fragments in an aligned state with their cleaved faces facing each other; a lengthwise direction pressing means that presses the plurality of magnet fragments from the lengthwise direction in which they are arranged to the lengthwise direction reference surface in order to align the magnet fragments in the lengthwise direction; a width direction pressing means that presses the plurality of magnet fragments from the width direction of the magnet fragments to the width direction reference surface to align them in the width direction; and a thickness pressing means that presses the plurality of magnet fragments from the thickness direction of the magnet fragments to the thickness direction reference surface to align them in the thickness direction.

Abstract: A manufacturing device for a field pole magnet body includes a reference jig having reference surfaces in the lengthwise direction, width direction, and thickness direction for positioning a plurality of cleaved and divided magnet fragments in an aligned state. The manufacturing device further includes a first pressing means that presses the plurality of magnet fragments to the thickness direction reference surface from the thickness direction of a magnet body to align them in the thickness direction, and a second pressing means that presses the plurality of magnet fragments to the width direction reference surface from the width direction of the magnet body to align them in the width direction. An operational axis line of a pressing part of at least one of the first and second pressing means is arranged to be tilted such that it approaches the lengthwise direction reference surface at the side that abuts the magnet fragments.

Abstract: A one-piece field-pole magnet is manufactured by filling a gap formed between magnetic pieces placed on a plane with an adhesive or resin. During the process, a pushing member applies a pushing force onto each of the magnet pieces in a thickness direction thereof. The pushing member comprises pushing parts each of which pushes each of the magnet pieces, thereby equalizing the pushing forces applied to the respective magnet pieces.

Abstract: There is provided a magnesium alloy member that includes an aluminum-containing magnesium alloy material. The magnesium alloy material has a modified layer formed at a surface thereof in such a manner that at least a surface of the modified layer has a higher aluminum content than that of any unmodified base portion of the magnesium alloy material.
