A speed regulating hand brake mechanism and method for speed regulation of the speed regulating hand brake mechanism is disclosed. The mechanism includes: a housing, wherein an installation cavity is defined inside the housing; a speed regulating button is hinged to the side wall of the housing; an installation cavity is internally provided with the driving part hinged to the speed regulating button; the rack is hinged to the driving part and can slide along the inner wall of the installation cavity in a horizontal direction after receiving the pressing force transmitted from the speed regulating button; the encoder is fixed on a first fixing plate in the installation cavity, the rack drives a gear arranged at the top of the encoder to rotate, and changes the code value output by the encoder; the elastic end of the return piece is located inside the speed regulating button.

A control apparatus for actuating hydraulic valve systems includes an actuation section including an oscillating control element and a plurality of control rods provided with a pusher capable of interacting with the control element so as to translate the control rods in a longitudinal direction, a sensor section including a plurality of sensor elements for detecting a movement in a longitudinal direction of said control rods, and an auxiliary section capable of generating a force opposing the motion of the control rods.

A vehicle steering assembly for controlling movement of a vehicle having independently rotatable left and right ground-engaging traction elements. The steering assembly comprises a steering handle coupled to the panel support structure and extending generally upwardly from the panel support structure. The steering handle comprises a laterally-extending crossmember and at least one upright extension member. The crossmember and the upright extension member are rigidly connected to one another so that shifting of the crossmember relative to the extension member is substantially prevented. The steering handle is shiftable in forward and rearward directions to thereby cause corresponding forward and rearward rotation of both of the left and right traction elements. The steering handle is rotatable in clockwise and counterclockwise directions to thereby cause a change in the relative speeds and directions of rotation of the left and right traction elements.

An operating device according to the present invention includes magnetic field generation means. The magnetic field generation means includes a coil generating a magnetic field when energized, and a yoke forming a magnetic path for the magnetic field passing through a rotor. A control unit includes magnetization means and rotational torque control means. The magnetization means supplies a current to energize the coil such that a residual magnetic field in the yoke is held at a predetermined magnitude. The rotational torque control means adjusts a current value applied to the coil in accordance with the magnitude of the residual magnetic field in the yoke. An absolute value of a maximum value of the current value applied to the coil by the rotational torque control means is smaller than an absolute value of a current value applied by the magnetization means.

Provided is an operating device comprising: an operation part which is inserted into an insertion hole portion of a glass part and has a locking protrusion portion having a protruding shape on the side surface thereof; and a locking rotation part which is disposed in a position opposite to the side surface of the operation part so as to allow or lock the movement of the locking protrusion portion, the locking rotation part comprising: a frame part having an inner hole portion into which the operation part is inserted; and a hollow hole part rotatably disposed in the frame part and communicating with the inner hole portion.
