    • The invention presents a method for manufacturing an amphoteric urethane resin, improving at least one of the performance of cosmetics including this amphoteric urethane resin and the storage stability of the urethane resin. The method for manufacturing an amphoteric urethane resin uses (A) a polyol; (B) a polyisocyanate; (C) a polysiloxane compound (except any having at least one selected from a hydroxyl group, a primary amino group and a secondary amino group at one or both ends of the siloxane chain); (D) a compound having carboxyl groups and at least one selected from a hydroxyl group, a primary amino group and a secondary amino group; (E) a compound having tertiary amino groups and at least one selected from a hydroxyl group, a primary amino group and a secondary amino group; and the method includes a step of making a prepolymer including isocyanate groups by reacting the compounds (A), (B) and (D) with excessive isocyanate groups; and a step of reacting the prepolymer including the isocyanate groups with the compound (E); wherein the compound (C) is present in at least one of the first step and the second step.
    • 本发明提供一种制造两性聚氨酯树脂的方法,改善包括该两性聚氨酯树脂在内的化妆品的性能的至少一个以及聚氨酯树脂的保存稳定性。 制造两性聚氨酯树脂的方法使用(A)多元醇; (B)多异氰酸酯; (C)聚硅氧烷化合物(除了在硅氧烷链的一端或两端具有选自羟基,伯氨基和仲氨基中的至少一种以外); (D)具有羧基和选自羟基,伯氨基和仲氨基中的至少一种的化合物; (E)具有叔氨基和选自羟基,伯氨基和仲氨基中的至少一种的化合物; 该方法包括通过使化合物(A),(B)和(D)与过量的异氰酸酯基团反应制备包含异氰酸酯基团的预聚物的步骤; 和使包含异氰酸酯基团的预聚物与化合物(E)反应的步骤; 其中化合物(C)存在于第一步骤和第二步骤中的至少一个中。

    • A variable focus optical element comprises plural elastic members superposed in the axial direction and a deforming member having an aperture to cause the elastic member to protrude therefrom or descend therein thereby deforming the surface of the elastic members, and the modulus of elasticity of an elastic member at the protruding side is selected larger than that of another elastic member adjacent to first-mentioned elastic member at the protruding side. A focus detecting device comprises an imaging optical system having a variable-focus optical element, an image sensor provided at a determined image plane of the imaging optical system or an optically equivalent position, a sharpness detecting device for detecting the sharpness of the image from image signals obtained from the image sensor, and a device for varying the refractive power of the variable-focus optical element, and the focus state of the image on the image sensor is detected by comparing the sharpnesses detected by the sharpness detecting device at plural refractive powers of the variable-focus optical element.
