Abstract: An armature coil includes a first portion, a second winding portion, a first winding end, a second winding end, and a crossover portion, and is continuously wound. The first winding portion is concentratedly wound in a counterclockwise winding direction with respect to a direction obtained in viewing a second end portion from a first end portion of a tooth, as it passes from the first winding end to the crossover portion. The second winding portion is concentratedly wound in a clockwise winding direction with respect to a direction obtained in viewing a second end portion from a first end portion of the tooth, as it passes from the crossover portion to the second winding end.

Abstract: A U-phase winding includes four winding portions connected in series between a neutral point and a U-phase input end. A V-phase winding includes four winding portions connected in series between the neutral point and a V-phase input end. A W-phase winding includes four winding portions connected in series between the neutral point and a W-phase input end. These winding portions are arranged annularly around a predetermined location. Directions in which these winding portions are each wound from a first winding end to a second winding end are the same as viewed from the predetermined location.

Abstract: A rotor includes a shaft, a hub that is fixed to one axial end part of the shaft, is configured to cover one axial end face of the shaft, and is made of a resin, a plurality of connection parts that radially outward extend from the hub of the rotor and are made of the resin, and an outer peripheral part that is disposed radially outside the hub and is connected to the hub via the connection parts. A resin injection gate mark is provided on one axial end face of the hub.

Abstract: A method for manufacturing an optical recording medium of the present invention includes the steps of forming an underlying layer having a brightness of 8 or more and a chroma of 4 or less on a label surface of a disk body by a spin coating process, and forming an ink-receiving layer on the underlying layer. In the present invention, the underlying layer having a brightness of 8 or more and a chroma of 4 or less is formed by a spin coating process, thereby significantly decreasing the surface roughness of the underlying layer. Even if the ink-receiving layer is formed by the spin coating or slit coating process in which the surface quality of the underlying layer is greatly reflected, therefore, the average surface roughness (Ra) of the ink-receiving layer can be significantly decreased. Thus, printing by an ink jet printer can produce a color and brilliance close to those of a silver salt photograph.

Abstract: An optical recording medium of the present invention includes a disk body and an ink-receiving layer disposed on a label surface of the disk body, wherein the ink-receiving layer has a brightness of 8 or more, a chroma of 4 or less, and an average surface roughness (Ra) of 0.1 ?m or less. Therefore, a colored layer of white ink need not be provided below the ink-receiving layer to simplify the manufacturing process. Furthermore, even when the ink-receiving layer is formed by a spin coating or slit coating process in which the surface quality of an underlying layer is greatly reflected, therefore, the average surface roughness (Ra) of the ink-receiving layer can be significantly decreased. Thus, printing by an ink jet printer can produce a color and brilliance close to those of a silver salt photograph.

Abstract: An optical recording medium is made by a step of bonding a light-transmissive substrate to a supporting substrate having a brightness of 8 or more and a saturation of 4 or less via a bonding layer composed of an epoxy resin; and a step of forming a transparent ink-receiving layer on a surface of the supporting substrate remote from the light-transmissive substrate. The bonding using the epoxy resin is conducted by a method of curing the resin by using a cationic initiator, a method of curing the resin by an addition reaction between the resin and a crosslinking agent containing an active hydrogen compound, a method of curing the resin by heating, or the like. In this invention, the bonding layer is composed of a material containing an epoxy resin instead of a radically polymerizable UV-curable resin typically used. Thus, although UV irradiation through the supporting substrate is not possible, the light-transmissive substrate can be securely bonded to the supporting substrate.

Abstract: An optical recording medium according to the invention has a disc body 11 in which a label side 11b can be viewed from a light incident side 11a, a printing layer 12 that is provided on the label side 11b of the disc body 11, and an ink receiving layer that is provided on the printing layer 12. Accordingly, the printed content of the printing layer 12 can be viewed from the light incident side 11a and a user can print a desired design on the ink receiving layer 13. Therefore, the design flexibility can be enhanced and a possibility of erroneous handling of the optical recording medium by the user can be drastically reduced. In addition, the optical recording medium by manufacturer or brand can be visually discriminated.

Abstract: An optical recording medium of the present invention includes a support substrate, a functional layer for storing data, and a transparent ink-receiving layer provided opposite to the functional layer with respect to the support substrate, wherein the support substrate has a brightness of 8 or more, and a chroma of 4 or less. Therefore, a colored layer of white ink need not be provided between the ink-receiving layer and the support substrate, thereby simplifying the manufacturing process. Also, the surface quality of the support substrate is reflected in the ink-receiving layer. For example, when the support substrate is formed by injection, therefore, the average surface roughness (Ra) of the ink-receiving layer is significantly decreased. Thus, printing by an ink jet printer can achieve a color and brilliance close to those of a silver salt photograph.
