Provided are a magnetorheological fluid rotational load device and a method of controlling the same. The magnetorheological fluid rotational load device includes a housing, a yoke fixed in the housing, a shaft rotatably mounted at the center in the housing, one or more rotation rings connected to the shaft to rotate in association with rotation of the shaft, a coil disposed in the housing, a magnetorheological fluid filling the housing.

An operation device of a work vehicle includes a position lever to set a height of a work device, a sensitivity adjustment lever to adjust an up/down sensitivity of the work device, and an up/down lever to selectively change a working state and a non-working state, the working state being a state in which the work device is positioned at the height set by the position lever, the non-working state being a state in which the work device is positioned above the set height. The up/down lever is located rearward of the position lever and the sensitivity adjustment lever.

The present disclosure provides a master manipulator device for a robot. The master manipulator device comprises an end control assembly and a posture adjustment member. The posture adjustment member includes a first rotation mechanism and a second rotation mechanism. The first rotation mechanism is connected to the end control assembly, and the second rotation mechanism is connected to the first rotation mechanism. The end control assembly drives the first rotation mechanism to rotate around a rotation axis of the first rotation mechanism, and the end control assembly also drives the first rotation mechanism and the second rotation mechanism to rotate around a rotation axis of the second rotation mechanism.

A magnetorheological braking device has two braking components that are continuously rotatable relative to one another. A first braking component extends in the axial direction and the second braking component includes a hollow casing extending around the first braking component. A peripheral gap is filled with a magnetorheological medium. The first braking component has an electric coil and a magnetically conductive core which extends in the axial direction. A star contour with magnetic field concentrators on the core and/or on the shell part project into the gap, which results in a peripheral gap region with a variable gap height. The electric coil is wound around the core such that a magnetic field runs through the core and the magnetic field concentrators and through the gap into a wall of the casing. A star contour is formed by a stack of star plates.

An accelerator pedal device of the present invention includes: an accelerator pedal; a hysteresis generation mechanism that generates a hysteresis in pedal effort during a depression operation and a return operation of the accelerator pedal; a reaction force addition mechanism that adds a reaction force in a direction to push back the accelerator pedal; and a control unit that controls the drive of the reaction force addition mechanism in a manner that, with a predetermined target opening degree at which the accelerator pedal is depressed as a boundary, a ratio of change in the pedal effort in an opening degree range above the target opening degree becomes relatively larger than a ratio of change in pedal effort in an opening degree range below the target opening degree.

The components of a push button comprise a plunger, a retainer, a spring and an end cap. The plunger has a button at the top, a middle section with an enlarged square cross-section, and a pin of reduced diameter at the bottom end. The plunger slidably strokes up and down within a retainer which has an upper portion that closely holds the button on the top of the plunger and also includes a rectilinear recess sized to receive the square midsection of the plunger. A middle portion of the retainer comprises an enlarged cylindrical cavity bounded above and below by opposing roof and floor surfaces. The roof and the floor have cams that engage the corners of the plunger midsection which cause it to rotate during plunger strokes. A spring within the retainer biases the plunger upward. The assembly of parts is captivated by a retainer end cap.
