The present invention addresses the problem of providing a one-way clutch and a one-way clutch-equipped rotating damper device with which it is possible to achieve size reduction. A pawl portion of a slide member comprises a withdrawal surface and an engaging surface. When a gear member rotates toward one side, as inner teeth and the withdrawal surface abut each other, the slide member slides in a sliding direction and the pawl portion is withdrawn from the inner teeth, whereby the gear member rotates independently of a rotor shaft. When the gear member rotates toward the other side as the inner teeth and the engaging surface abut each other, the inner teeth and the engaging surface become engaged, whereby the gear member and the rotor shaft rotate integrally.

A prosthesis device has a rotary damper and a displacing device with a magnetorheological fluid in a damper volume of a housing. Two partition units divide the damper volume into two or more variable chambers. The partition units include a partition wall connected with the housing and a partition wall connected with a damper shaft. Radial gaps are formed in the radial direction between the partition wall on the housing and the damper shaft, and between the partition wall on the damper shaft and the housing. An axial gap is formed in the axial direction between the partition unit, the damper shaft and the housing. The magnetic field of the magnetic field source passes through at least two of the gaps.

This damper comprises: a housing accommodating a damping medium; and a rotor rotatable relative to the housing, inside the housing. A unidirectional clutch which stipulates rotation in one direction and a rotating shaft can be connected to each other coaxially. The unidirectional clutch, when supporting the rotating shaft, constitutes a first input object, whereas the rotating shaft constitutes a second input object when not being supported by the unidirectional clutch. A connection object comprises a first connection part capable of connecting to the first input object coaxially, and a second connection part capable of connecting to the second input object coaxially. Two separate connection states are provided, namely a state in which the first connection part and the first input object are connected to each other, and a state in which the second connection part and the second input object are connected to each other.

A torque generating device includes a magnetic disk configured to rotate around a rotation axis, first and second yokes located on opposite sides across the magnetic disk, a coil disposed to overlap the magnetic disk along a direction of the rotation axis, a third yoke of which at least a region proximity to the magnetic disk is located outside the magnetic disk and the coil and that makes up a magnetic path of a magnetic field generated by the coil with the first and second yokes, and a magnetic viscous fluid filled between the magnetic disk and the first and second yokes. The third yoke has a magnetic gap between the third and first yokes. The magnetic gap is formed at a position outside an outer peripheral edge of the magnetic disk or overlapping the outer peripheral edge of the magnetic disk along the direction of the rotation axis.

A system and method that pertain to a rotating vehicle display unit that can automatically or manually rotate between landscape and portrait orientations, depending on the particular display format or media being shown to the vehicle occupants. The rotating vehicle display unit uses an electro-mechanical rotating and locking mechanism with smart fluid, such as magnetorheological fluid (MR), to facilitate easy and precise rotational movement between different display orientations. The rotating vehicle display unit may be coupled to a corresponding human-machine interface (HMI) that responds to the different display orientations and helps facilitate easy transition from one orientation to another in order to optimize the particular display format or media being shown at that time.

An input device, such as a joystick, has an operating device, a magnetorheological brake device, and a controller for activating the brake device. An operating lever is disposed on a supporting structure for pivoting around at least one pivot axis. The brake device is coupled with the pivot axis for controlled damping of a pivoting motion of the operating lever. The brake device has a rotary damper with two components, namely, an inside component and an outside component. The outside component radially surrounds the inside component and a damping gap is formed in between that is filled with a magnetorheological medium. The damping gap can be exposed to a magnetic field to damp a pivoting motion between the two contrapivoting components about an axis. One of the components has radial arms equipped with an electric coil whose winding extends adjacent to and spaced apart from the axis.

Inerters with friction disk assemblies, and aircraft hydraulic systems and aircraft including the same. An inerter comprises an inerter housing containing an inerter fluid, a threaded shaft extending within the inerter housing and fixed relative to the first terminal, and an inerter rod extending at least partially within the inerter housing and fixed relative to the second terminal. The inerter further includes a friction disk assembly that, together with the inerter fluid, is configured to damp a motion of the second terminal relative to the first terminal. The friction disk assembly includes a fixed portion and a rotating portion, and is configured such that rotation of the rotating portion generates a frictional torque that opposes the rotation of the rotating portion. In some examples, the inerter is a component of a hydraulic actuator, an aircraft hydraulic system including the hydraulic actuator, and/or an aircraft including the aircraft hydraulic system.
