20090236926 | Rotor for rotating electrical machine and method of manufacturing same - In a rotor for a rotating electrical machine, a flange of an insulating bobbin is formed with a first hook portion and a second hook portion. The first hook portion directs a lead of a field coil both against the winding direction of the field coil and radially inward. The first hook portion has a first groove in which is hooked a proximal portion of the lead. The second hook portion directs the lead axially outward. The second hook portion has a second groove which has an open end on a radially inner periphery of the second hook portion, a closed end positioned radially outward of the open end, and a neck between the open and closed ends. The second hook portion has an intermediate portion of the lead hooked in the second groove between the neck and closed end of the second groove. | 09-24-2009 |
20110041320 | Stator with winding formed of a series of segments for electric rotating machine and method of manufacturing the stator - A stator has conductor segments serially wound on a core. Each segment inserted in one of slots of the core has a slanting portion protruding from the slot and inclined toward circumferential and axial directions of the core. Each slanting portion has an oblique portion with a film removal surface and a film removal portion with a film removed surface to have a slanting removal area covered with no insulation film and extending on the oblique portion. Each film removal portion has a connection portion on an end thereof. The connection portions are aligned along a radial direction of the core to form a plurality of end pairs. The connection portions of each end pair are connected with each other so as to serially connect the segments with one another. | 02-24-2011 |
20110241471 | ROTOR OF ELECTRIC ROTATING MACHINE - A rotor of alternator has core layer units serially located along axial direction. Each unit has a field coil generating magnetic flux and two rotor cores receiving the flux on respective sides of the coil in axial direction. Each core has a first yoke portion located on inner side of the coil, a second yoke portion extending from the first yoke portion toward the outer side and magnetic poles extending from the second yoke portion in the axial direction. The poles of one core and the poles of the other core in each unit extend toward different axial sides and are alternately arranged in circumferential direction on the outer side of the coil. A ratio of the outer circumferential diameter of the first yoke portions to the rotational diameter of the poles is lower than 0.54. | 10-06-2011 |
20140132104 | STATOR WINDING AND METHOD OF MANUFACTURING THE SAME - There is provided a winding to be wound at a stator of a rotary electric machine. The winding is produced from a flat wire having a rectangular cross section along a plane perpendicular to a length-wise direction. The flat wire is coated with an electric insulating layer and is bent to have curves at given portions of the flat wire in the length-wise direction. The curves are located on an axial outer side of the stator. The cross section of the flat wire has four corners, among which mutually-adjacent two corners are lager in curvatures than remaining mutually-adjacent two corners. The mutually-adjacent two corners whose curvatures are smaller are positioned on a circumferential outer side of each of the curves and the mutually-adjacent two corners whose curvatures are larger are positioned on a circumferential inner side of each of the curves. | 05-15-2014 |
20140300237 | STATOR FOR ROTATING ELECTRIC MACHINE - A stator includes an annular stator core and a stator coil. The stator coil is formed of electric conductor segments each of which is bent in its thickness direction to include, at least, an in-slot portion and an oblique portion. The in-slot portion is received in a corresponding slot of the stator core with its width direction coinciding with a radial direction of the stator core. The oblique portion protrudes from the in-slot portion outside the corresponding slot and extends, over its entire length, along the circumferential direction of the stator core obliquely with respect to an axial end face of the stator core. The oblique portion includes a thick section on the proximal side and a thin section on the distal side. Each corresponding pair of the oblique portions of the electric conductor segments are connected by joining the thin sections of the oblique portions. | 10-09-2014 |

20120107773 | Fiber Abutment Material and Structure of Dental Implant - A fiber abutment material and structure of dental implant includes: a fiber resin abutment equipped with plural fiber center shafts, such as glass fiber center shaft, carbon fiber center shaft, quartz optical fiber center shaft, or glass fiber optics center shaft, in which the single, dual-layer or multi-layer fiber multiply enhances the intensity, and the fiber resin abutment with grind ability is easily modified on-site for the dentist, is equipped with considerable fibers with tensile strength higher than that of titanium or zirconia (ceramic), because of the fiber structure elasticity similar to natural tooth to be shock absorbed, to prevent the bone from hurting and decrease the damage to the base. | 05-03-2012 |
20120321259 | LIGHT-TRANSMITTABLE COMPOSITE TUBE - A light-transmittable composite tube includes a plurality of optical fibers and a plastic material. Each of the optical fibers has a light entrance end and a light exit end. Light enters the light entrance end and emits from the light exit end. The plastic material is set around and combined with side surfaces of the optical fibers in a composite form to fix relative positions of the optical fibers to form a tubular structure, serving as a fiber/plastic composite light guide tube. The fiber/plastic composite light guide tube has a light receiving end opening and a light emitting end opening, wherein the light exit ends of the fibers are arranged to distribute in the light emitting end opening and face outward of the light emitting end opening. | 12-20-2012 |
