A method of manufacturing a stator coil for an electric rotating machine includes the steps of: (1) forming substantially planar electric wires each of which includes in-slot portions to be received in slots of a stator core and turn portions to be located outside the slots to connect adjacent pairs of the in-slot portions; (2) rolling each of the planar electric wires through plastic deformation into a spiral or circular-arc shape; and (3) assembling the rolled electric wires together to form the stator coil. Further, in the rolling step, each of the planar electric wires is rolled by deforming each of the turn portions of the electric wire while restricting movement of at least one of the in-slot portions of the electric wire which is located closer to a rolling start end of the electric wire than the turn portion is.

摘要:
The present invention provides a method for stabilizing fine particles of calcium phosphates without lowering their solid phase forming activity.It is possible to stabilize the fine particles of calcium phosphates by stopping the growth of the fine particles formed in an aqueous solution supersaturated with respect to calcium phosphates. More specifically, the fine particles of calcium phosphates were stabilized by lowering the inorganic ion concentration of a fine-particle-forming solution containing fine particles of calcium phosphates by dialysis, ion exchange, dilution, or the like, or by separating the fine particles of calcium phosphates from the fine-particle-forming solution by filtration, centrifuging, or the like.
