A media channel assembly for an internal combustion engine includes at least one distribution channel for distributing a medium to various components of the internal combustion engine, and at least one supply channel, which is coupled to the distribution channel by way of at least one media passage opening. At least a wall region of the distribution channel lying opposite the media passage opening is curved, at least in parts, toward the media passage opening. An internal combustion engine includes such a media channel assembly, and a motor vehicle includes such an internal combustion engine.

A resin material is injection-molded using an injection mold in which a resin flow channel is designed so that a plurality of gates are provided along a longitudinal direction at a position corresponding to an inner circumferential surface of a spacer, to obtain a molded product, the spacer having a shape that a plurality of arc-shaped circumferential surfaces are linked through a constricted part. The molded product is cooled in a state in which a runner that is connected to the gates is allowed to remain, and the runner is cut off thereafter. A water jacket spacer is produced by injection molding while achieving excellent moldability, the water jacket spacer being disposed in a water jacket, and controlling the flow of a coolant, the water jacket spacer including a plurality of segments, or having a shape that the water jacket spacer can be partially inserted into the water jacket.

A method of manufacturing the synthetic resin welded body includes the steps of: preparing an oil passage forming member including a welding portion having a top portion serving as a welding face; preparing a baffle plate having a welded face; disposing the oil passage forming member and the baffle plate so that the welding face comes in contact with the welded face; and radiating laser light to the welding portion to weld the welding face and the welded face. A recess is formed in the baffle plate so that a groove portion is formed along an outer peripheral face of the welding portion when the oil passage forming member and the baffle plate are disposed so that the welding face comes in contact with the welded face.

A field magnet manufacturing method where a bonded magnet's inner surface press-fitted in a yoke has a certain accuracy irrespective of the accuracy of the yoke's outer circumferential surface. A cylindrical bonded magnet from binding magnet particles with a thermosetting resin is fixed in a tubular yoke of magnetic material. The method includes reheating and softening the bonded magnet after thermal curing; and press-fitting in the bonded magnet after the softening step from a tapered portion on one end side of the yoke to press the bonded magnet's outer circumferential surface against the yoke's inner surface. The press-fitting includes feeding the bonded magnet relatively into the yoke while allowing a relative posture variation between the bonded magnet and the yoke so the bonded magnet's inner surface to be remolded into a shape along the inner surface of the yoke exhibits almost the same accuracy as the yoke's inner surface.

An apparatus for forming pre-shaped insulating sheets comprises a first bending station and a second bending station. The first bending station is used for bending a flat sheet of insulating material into a Z-shaped sheet (5). The second bending station is used for bending the Z-shaped sheet into an S-shape. The first and second bending stations comprise pairs of first (13a, 13b) and second bending operators for creating bending movements.

A speed reducer casing of the present invention has inner teeth on an inner periphery thereof. The speed reducer casing includes an inner tooth portion and a casing body portion, the inner tooth portion including the inner teeth, the casing body portion supporting the inner tooth portion. The inner tooth portion is formed of a material having a higher slidability than the casing body portion. The casing body portion is formed of a material having a higher hardness than the inner tooth portion.

A heating apparatus for heating an object having a cylindrical outer peripheral surface includes: a support member for supporting the object to be heated; a covering member movable in the vertical directions relative to the support member and having inner wall surfaces with an open lower end, the inner wall surfaces defining an accommodation space for accommodating the object to be heated; the covering member closing the accommodation space when the covering member is disposed on the support member; the covering member allowing loading or unloading of the object to be heated when the covering member is separated from the support member; and a plurality of ring-shaped light sources each provided to surround the cylindrical outer peripheral surface of the object to be heated and arranged in the vertical direction in the accommodation space and radiating light for heating the object to be heated.

The invention relates to a method for assembling a first metal part with a second part made of an organic matrix composite material, the first part having a first connecting portion and the second part having a second connecting portion, the method comprising the steps of: causing the first connecting portion and the second connecting portion to overlap, a through-hole of the second connecting portion opening onto the first connecting portion, forming a protective layer on the side wall of the through-hole, forming a seal between the protective layer and the first connecting portion, and forming, by additive manufacturing using cold gas spray deposition of metal powder, a fastening element which extends into the through-hole, is fastened to the first connecting portion and encloses the second connecting portion.

Provided is a manufacturing device and a manufacturing method for a rotor core that can prevent damage from being caused to an end of a magnet due to movement of the magnet when injecting a resin material. Included are a first mold including a fitting recess that fits and holds a laminated iron core in which a magnet is inserted into a magnet insertion hole, a second mold that is engaged with the first mold and clamps and seals the laminated iron core together with the first mold, a resin injection unit that is provided to the second mold, and injects a resin material into the magnet insertion hole, and a magnet positioning and holding mechanism that positions and holds the magnet in a state of being fit into the fitting recess of the first mold.
