  • Publication number: 20230012643
    Abstract: To provide a method for predicting the c-axis length of a lithium compound crystal structure, a method for building a learning model for predicting a c-axis length, and a system for predicting a crystal structure having the maximum c-axis length. A method for predicting the c-axis length of a crystal structure of a lithium compound containing cobalt, nickel, and manganese includes preparing a descriptor including n values (n is an integer greater than or equal to 0) obtained by converting a crystal structure of the lithium compound in which manganese at any one or more of n sites is substituted by a metal atom among crystal structures of the lithium compound into binary data and a characteristic value of the metal atom; inputting the descriptor into a learned learning model; and outputting a predicted value of c-axis length of an optimized crystal structure and a descriptor corresponding to the optimized crystal structure as an output value of the learning model.

  • Patent number: 11505239
    Abstract: A steering system includes a steered shaft, a ball screw nut, balls, a housing, a rolling bearing, and a snap ring configured to prevent the rolling bearing from detaching from the ball screw nut. The rolling bearing includes double-row rolling element arrays, an outer ring, a first inner ring, and a second inner ring. The ball screw nut has a receiving portion. The snap ring contacts a side face of the second inner ring to push the second inner ring toward the receiving portion via the first inner ring. A resistance force received from the second outer peripheral fitting surface when the second inner ring moves in the axial direction in a state in which detachment of the rolling bearing is not prevented by the snap ring is smaller than a pushing force with which the snap ring pushes the second inner ring.
