b 55773576.001A disk having a non-uniform thickness with a thickness of an end portion thereof being smaller than a thickness of a hub coupling portion and a thickness of a hat portion being smaller than the thickness of the end portion. As a result, rigidity of the hat portion is decreased so that stress distribution in the disk is uniform and excess stress concentration is prevented from influencing a weld portion. Further, because of the decrease in thickness, weight of the disk also is decreased as compared to conventional disks.

Two cloths stretchable in all the directions can be sewed together beautifully. Each stretchable cloth includes an outer edge, a first sewing line situated away from the outer edge to thereby form a free end between the outer edge and the first sewing line, and a main portion. The cloths are laminated and sewed along the first sewing lines to form an outer stitch. Then, at least one of the two stretchable cloths is turned, so that the free ends of the stretchable cloths are covered by at least one of the main portions. Thereafter, the stretchable cloths are sewed along a second sewing line outside the free ends while the free ends are stretched in a direction away from the second sewing line to thereby form a holding stitch. Accordingly, the two stretchable cloths are sewed beautifully and stretchably.

摘要:
A garment has a collar/lapel which is produced by folding a part of the boundary area between a body piece and a flyback. A first expansible and contractible interfacing member is fitted to an area of the body which becomes the rear side of the collar/lapel when it is folded but no interfacing is fitted to the area of the flyback which becomes the front side of the collar/lapel when it is folded. A second expansible and contractible interfacing member is fitted to the area of the flyback which becomes a rear side of the collar when it is folded. A stitch by means of which the first expansible and contractible member is sewn to the body is provided in the proximity of the position where the first expansible and contractible interfacing member fitted to the body is folded as a collar. Another stitch by means of which the second expansion and contractible interfacing member is sewn to the flyback is provided in the proximity of the position where the second expansible and contractible interfacing member fitted to the flyback is folded as a collar. A free end part of the first expansible and contractible interfacing member and a free end part of the second expansible and contractible member are joined to one another with the aid a stitch or adhesive.

摘要:
A method and apparatus for electrolytically extracting lithium at high purity and high efficiency are disclosed, in which the apparatus 1 includes a partition 2 constituted mainly of a perovskite-type Li ion conducting solid electrolyte, a feed chamber formed on one side of the partition in which a crude liquid containing a lithium component and impurities is introduced so as to come into contact with the partition, a recovery chamber formed on the other side of the partition in which a liquid for recovery is introduced so as to come into contact with the partition, and a means for applying an electrical field to the partition in such a manner that the crude liquid side is positive and the recovery liquid side is negative. On applying an electrical field to the partition, the lithium component of the crude liquid selectively passes through the partition in the form of Li ions into the recovery side.
