  • Patent number: 11305832
    Abstract: A left suspension unit supports a left wheel. A right suspension unit supports a right wheel. A steering actuator imparts a force causing the left suspension unit and the right suspension unit to turn about a left steering axis and a right steering axis respectively to a steering force transmission mechanism. A leaning actuator imparts a force causing a body frame to lean leftward or rightward of a leaning vehicle to a link mechanism. A control unit is capable of selecting a first mode wherein both of the steering actuator and the leaning actuator are employed, and a second mode wherein the steering actuator is employed without employing the leaning actuator, in order to control a leaning angle of the body frame in cooperation with a steering mechanism.

  • Patent number: 11107597
    Abstract: A cask includes a cask body, an outer cylinder, a plurality of fins, and a plurality of neutron shields. The cask body has a tubular shape around a central axis and is capable of housing fuel assemblies. The outer cylinder has a tubular shape surrounding the cask body. The fins are aligned in a circumferential direction in a tubular space formed between the cask body and the outer cylinder, and connect an outer peripheral surface of the cask body and an inner peripheral surface of the outer cylinder to divide the tubular space into a plurality of divided spaces. The neutron shields contain a neutron shielding material with which the divided spaces are filled. Each neutron shield includes a void portion extending in the axial direction along the central axis. Accordingly, it is possible to reduce stress that may be exerted on the outer cylinder or other components by thermal expansion of the neutron shielding material when the fuel assemblies are housed in the cask.
