  • Patent number: 10378647
    Abstract: A shift lever device includes: a lever main-body; a hollow knob provided at a lever main-body distal end portion; a shift-button rotatably mounted to the knob; and a rod that is inserted-through interior of the lever main-body. The shift-button has a contact surface extending in direction of being away from a rotating-shaft of the shift-button, and that, when the shift-button rotates with respect to the knob, contacts an upper end portion of the rod and lowers the rod. Given that direction orthogonal to axial-direction of the rotating-shaft on plane orthogonal to axis of the rod is reference-direction, and that, among tangent-lines at contact points of the contact surface and the rod, tangent-line on plane orthogonal to the rotating-shaft is reference tangent-line, rotation range of the shift-button is set such that, partway through rotation, the reference tangent-line passes position at which the reference tangent-line becomes parallel to the reference-direction.

  • Patent number: 9512409
    Abstract: An object is to efficiently produce thermostable catalase at low cost by expressing it as a recombinant protein in large quantity. A recombinant microorganism capable of efficiently expressing thermostable catalase can be provided by obtaining a DNA necessary for efficiently producing it as a recombinant protein, and the thermostable catalase can be efficiently produced at low cost by cultivating the obtained recombinant microorganism. Hydrogen peroxide can be efficiently decomposed at low cost, even at high temperature, by treating a solution containing hydrogen peroxide with the thermostable catalase of the present invention.

  • Patent number: 8697409
    Abstract: Disclosed are a ketoreductase mutant which can be used for an efficient production of daunorubicin derivatives, a DNA encoding the mutant, a transformant prepared by introducing the DNA thereinto to produce a daunorubicin derivative, and a process of producing a daunorubicin derivative using the transformant. The ketoreductase mutant has an amino acid sequence in which one amino acid residue or two or more amino acid residues selected from the group consisting of amino acids located at positions corresponding to the 42nd, 149th, 153rd, 270th, and 306th amino acids in the amino acid sequence of a ketoreductase (EvaE) from a chlororemomycin-producing bacterium (Amycolatopsis orientalis) are substituted with another amino acid residues.
