Abstract: The manufacturing method for a rotor includes steps of: applying an adhesive to a first surface of a magnet material member that becomes a permanent magnet after magnetization, the adhesive being applied such that a total thickness of the magnet material member and the adhesive is less than a radial width of a magnet insertion aperture; disposing a rotor core such that an axial direction thereof is horizontal, and inserting the magnet material member into a magnet insertion aperture that is positioned vertically uppermost among the magnet insertion apertures so as to orient the adhesive vertically upward; positioning each of the magnet material members by pressing the magnet material member against an inner wall surface on an outer circumferential side of the magnet insertion aperture after inserting the magnet material member into each of the magnet insertion apertures; and curing the adhesive after the magnet material member is positioned.

Abstract: In an embedded magnet rotor for a rotary electric machine, permanent magnets are respectively accommodated in magnet housing apertures that pass axially through a rotor core that is held by a shaft, an adhesive is injected into and cured in gaps between the permanent magnets and the rotor core in the magnet housing apertures, and fixes the permanent magnets to the rotor core, a first end plate is held by the shaft so as to contact a first axial end of the rotor core, and blocks first axial end openings of the plurality of magnet housing apertures, and a fill rate of the adhesive that is injected into the gaps is increased gradually from a first axial end toward a second axial end of the magnet housing apertures.

Abstract: A method of forming a colored coating film on a cross-linked polyethylene comprises coating a coloring paint prepared by blending a prepolymer having acryloyl and/or methacryloyl groups in the molecule, a monomer and/or oligmer having the above-mentioned groups in the molecule and a pigment on the surface of cross-linked polyethylene and then curing the paint under the irradiation of UV-rays.

Abstract: A coating thickness regulating device for regulating the thickness of the paint film coating an elongate article, such as a wire, a pipe or the like, in coating the elongate article by an elongate article coating system. The device comprises a spreading block having a cavity consisting of a cylindrical section and a taper section, an outlet opening, an inlet opening and through holes opening into the cavity; a spreading element formed of a nonwoven web formed by laminating webs of elastic and abrasion-resistant fibers, such as stainless steel fibers and/or copper alloy fibers, and packed in the cavity of the spreading block so as to receive and pass a coated elongate article therethrough; and pressing means for adjustably compressing the spreading element so that the coated elongate article is passed properly through the spreading element to form a uniform paint film having a desired thickness over the surface of the elongate article.
