Dynamoelectric machine having holding grooves recessed into yoke portions with openings on respective facing portions of inner wall surfaces of trough portions, at axially inner ends of the yoke portions, having axial groove directions, and an end surface in a groove length direction constitutes a stopping surface. Magnet material holders are disposed spanning the trough portions radially inside inner circumferential surfaces near tip ends of claw-shaped magnetic pole portions, fitted from axially inside into each holding groove, are recessed to face each other on the trough portions restricting circumferential and radial motion by inner wall surfaces of the holding grooves and axially outward movement restricted by the stopping surface. Interfitting grooves having openings on surfaces facing the inner circumferential surfaces near the tip ends, having axial groove directions, and passing through in the axial direction, and permanent magnets fitted into the interfitting grooves are held by the magnet material holders.

An interfitting groove is disposed in a bottom portion of a trough portion so as to have a groove direction that is axial and so as to extend axially outward from axially inside, and a rotation arresting portion housing recess portion is recessed into an axially inner opening edge portion of the interfitting groove on a first yoke portion. A magnet holding seat that holds a permanent magnet is disposed in the trough portion by an interfitting portion being fitted into the interfitting groove such that radial movement is restricted. A rotation arresting portion that is disposed so as to project axially outward from a flange portion of the bobbin is housed inside a space that is constituted by the rotation arresting portion housing recess portion and an external shape reduced portion that extends axially inward from the interfitting groove such that rotation of the bobbin around the shaft is restricted.

An automotive dynamoelectric machine that achieves disposing of permanent magnets and thickening of field coil wire by ensuring outlet space for field coil lead wires. In the dynamoelectric machine, trough portions are formed on portions of yoke portions between respective circumferentially adjacent claw-shaped magnetic pole portions. Magnet holders are disposed so as to span over all of the trough portions on a pole core body at a rear end excluding a predetermined trough portion, and permanent magnets are held in each of the magnet holders. A field coil lead wire is led out from the rotor so as to pass through the trough portion over which a magnet holder is not disposed.

When a glass fiber and an inner fiber coating layer are to be attached to a connector by removing an outer fiber coating layer while leaving the inner fiber coating layer as it is, a collective coating and the outer fiber coating layer can be removed at a stretch so that the inner fiber coating layer can easily and satisfactorily be exposed. In the ultraviolet curable resin coating layer of a coated optical fiber 17 of an optical fiber ribbon 11 for wiring of equipment, the inner fiber coating layer 15 has a Young's modulus of 600 MPa to 1000 MPa, and the outer fiber coating layer 16 has a Young's modulus of 10 MPa to 300 MPa. The material of the outer fiber coating layer 16 is made by mixing 100 weight parts of base resin, 1-30 weight parts of silicone-based additive, and 0.5 to 40 weight parts of long chain fatty acid ester compound, wherein the base resin is a material made of a urethane metha acrylate oligomer, a mono-functional or multi-functional reactive dilution monomer, and an optical initiator.

A method of manufacturing a stator in a rotating electric machine. In this method, each slot has a slot peripheral wall and a slot opening, covered with an insulation coating made of an electrical insulation material. The slot peripheral wall SW has a slot bottom wall, a pair of slot side walls opposing to each other and continuing to end portions of the slot bottom wall. The insulation coating is formed continuously from the slot bottom wall to the pair of slot side walls, and a pair of holding grooves opposing to each other is formed in the insulation coating at the vicinity of the slot opening. The groove walls of the pair of the holding grooves are formed in the insulation coating, and an electrical insulation member to close the slot opening is inserted in the pair of holding grooves and held between the pair of holding grooves.
