  • Patent number: 11117272
    Abstract: A variable-stiffness actuator is to be installed into a flexible member and provide different degrees of stiffness to the flexible member. The actuator includes two hard members located apart from each other, and a shape-memory member connecting the hard members. The shape-memory member has a property of transitioning in phase between a first phase and a second phase. The shape-memory member is in a low stiffness state when in the first phase, and is in a high stiffness state when in the second phase. The actuator also includes a inducing member configured to cause a portion of the shape-memory member between the hard members to transition in phase between the first and second phases, and a urging member configured to urge the hard members in directions away from each other.

  • Patent number: 10862403
    Abstract: A power inversion apparatus includes a smoothing capacitor, first and second primary coils, a secondary coil, first to fourth switches of bridge circuit switches, a clamp capacitor, and a switch controller. The switch controller calculates a lower-arm duty ratio of each of the first and second switches using a map or a mathematical expression by feed-forward control based on an input voltage. The switch controller outputs a fixed value that is equal to or greater than a maximum value of the lower-arm duty ratio within a variation range of the input voltage as an upper-arm duty ratio of each of the third and fourth switches. The switch controller generates a pulse width modulation signal based on the calculated lower-arm duty ratio and the fixed value of the upper-arm duty ratio, and outputs the pulse width modulation signal to the bridge circuit switches.

  • Patent number: 10850619
    Abstract: A power conversion device includes a backup power source as a power source for a discharge controller that discharges electric charges of a capacitor, and an abnormal state in the backup power source or loads is not capable of being dealt with when power is supplied to loads from the backup power source, which makes an output voltage of the backup power source be in an abnormal state. In order to solve the problem, when an abnormality occurs in the backup power source or in loads and the abnormality is detected in power supply from the backup power source, a place where the abnormality occurs is specified. When the specified place where the abnormality occurs is a load, power supply to the load is stopped, thereby preventing the output voltage of the backup power source from being abnormal even when an abnormality occurs in part of power supply destinations.
