The obtained diastereomer salt is dissociated using an acid aqueous solution containing the optically active diacyltartaric acid, for recovering the optically active diacyltartaric acid, and the obtained optically active diacyltartaric acid is recycled into an optical resolution step as a raw material of the optical resolution step.

摘要： The present invention provides a wire for a press-connecting terminal which has a high flexibility, and achieves a high reliability for a connection portion at the time of press-connection, and also provides a method of producing a conductor of such a wire. The wire provides a stranded conductor and an insulator covering the conductor. Wire elements of the stranded conductor are concentrically twisted in layers in the same direction at the same pitch, and the stranded conductor is compressed into a circular cross-section in such a manner that a space factor of the cross-section of the conductor is not less than 99%. The present invention also provides a multi-layer compressed concentric stranded conductor which enables a uniform compression of a base stranded wire. Not more than 61 wire elements of the same diameter are twisted together in such a manner that the number of the wire elements of a Nth layer except for the central wire element is 6N and that a line, interconnecting the centers of the wire elements of each of those layers including a second layer and any other layer outside of the second layer counting from the central wire element, has a dodecagonal shape, and subsequently the thus twisted wire elements are compressed into a circular cross-sectional shape.

摘要： A twisted wire manufacturing apparatus is provided with a plurality of injection dies communicating with an annular groove formed in a rotary head. An annular shoe for gradually reducing a sectional area of the annular groove is slidably fitted to the annular groove. Raw material is supplied into the annular groove and raw wires are injected from the injection dies. One of the plurality of injection dies provides an increased injection resistance to reduce the injection speed of a core raw wire injected from that injection die relative to the injection speed of outer layer raw wires injected from other injection dies.
