摘要:
A cylindrical alkaline battery of the present invention includes a positive outer can in the form of a cylinder having a bottom and an opening at its top, a sealing member located along the inner edge of the opening, and a negative terminal for sealing the opening along with the sealing member. The negative terminal is caulked to the inner edge of the opening of the positive outer can via the sealing member. The positive outer can is formed of a metal plate including crystal grains with a grain size number of 9 to 12. A soft nickel-plating layer is deposited on both sides of the metal plate. The cylindrical alkaline battery further includes either or both of the following two configurations. Configuration 1: The surface roughness Ra of a portion of the positive outer can that comes into contact with the sealing member is 2 or less. Configuration 2: In the portion of the positive outer can that comes into contact with the sealing member, there are exposed portions of the metal plate due to cracks of the soft nickel-plating layer in the direction of the cylinder axis of the positive outer can, and the width of the exposed portions of the metal plate in the direction perpendicular to the cylinder axis is 100 μm or less.

摘要:
The present invention relates to a method for producing an optically-active amine compound. The method is characterized by using a transaminase (A), an α-keto acid reductase (B), and an enzyme (C), each having specific properties, in an identical reaction system to convert a ketone compound into a corresponding optically-active amine compound in which a carbon atom with an amino group bonded thereto serves as an asymmetric point. The present invention also relates to a recombinant vector for use in the method. The present invention makes it possible to efficiently produce an optically-active amine compound.
