    • The present invention relates to a method for producing an optically active 3-aminopiperidine or salt thereof. In the method, a racemic nipecotamide is stereoselectively hydrolyzed to obtain an optically active nipecotamide and an optically active nipecotic acid in the presence of an enzyme source derived from an organism, and then the optically active nipecotamide is derived into an optically active aminopiperidine or salt thereof by aroylation, Hofmann rearrangement, deprotection of the amino group and further deprotection; or the optically active nipecotamide is derived into an optically active aminopiperidine or salt thereof by selective protection with BOC, Hofmann rearrangement and further deprotection. It is possible by the present invention to produce an optically active 3-aminopiperidine or salt thereof useful as a pharmaceutical intermediate from an inexpensive and easily available starting material by easy method applicable to industrial manufacturing.

    • A tandem type master cylinder is disclosed having a housing with a through-bore defining an intermediate portion and opposed end portions. The diameter of each end portion is larger than the diameter of the intermediate portion, and the junctures between the end portions and the intermediate portion define step parts within the housing. Seal assemblies are positioned within the housing at the step junctures formed by the intermediate portion and the end portions and are retained in position by a plug secured within each end portion. Primary and Secondary pistons are disposed for guided movement along the intermediate portion of the housing, and return springs are provided within the housing for urging each piston to its initial rest position.
    • 公开了一种串联式主缸,具有具有限定中间部分和相对端部的通孔的壳体。 每个端部的直径大于中间部分的直径,并且端部和中间部分之间的接合部限定了壳体内的台阶部分。 密封组件在由中间部分和端部形成的台阶接合处定位在壳体内,并且通过固定在每个端部内的插塞保持就位。 主活塞和次级活塞设置成沿着壳体的中间部分引导运动,并且复位弹簧设置在壳体内,用于将每个活塞推到其初始静止位置。
