  • Publication number: 20210167355
    Abstract: Provided is a method for manufacturing an active material mixture, the method including: supplying and dispersing a solid electrolyte in a dispersion medium while circulating the dispersion medium (a first dispersion step); and thereafter supplying and dispersing an active material and a conductive material in the dispersion medium (a second dispersion step), wherein an average rotation speed of the rotor in the second dispersion step is lower than an average rotation speed of the rotor in the first dispersion step. Aggregation of the solid electrolyte can be suppressed by separately performing the first dispersion step and the second dispersion step, and the increase in temperature of the active material mixture can be reduced by lowering the rotation speed of the rotor in the second dispersion step.

  • Patent number: 10870840
    Abstract: The present invention addresses a problem of providing a lipase derived from a microorganism that is specific for short-chain to medium-chain fatty acids. A modified lipase is obtained by making a substitution in the amino acid sequence of a Candida cylindracea derived lipase, wherein the substitution is (1) a substitution of asparagine for an amino acid corresponding to the amino acid at position 428 in the amino acid sequence set forth in SEQ ID NO: 1; or (2) a substitution of phenylalanine, methionine, or isoleucine for an amino acid corresponding to the amino acid at position 429 in the amino acid sequence set forth in SEQ ID NO: 1.
