A position holding device for a rotating lever includes a rotating lever and a torsion spring. The rotating lever is elastically held at two positions, that is, a first position and a second position. The torsion spring includes a coiled part, and a first arm part and a second arm part each extending from the coiled part. The first arm part has a mountain portion formed thereon, and the second arm part has a reversely urging portion formed thereon. An urging force of the reversely urging portion is applied to the rotating lever as a braking force against an urging force of the mountain portion. Further, a regulating member is formed on a base member so as to abut against the first arm part when the rotating lever rotates toward the first position through a neutral position.

An oscillation decoupling system does not transmit oscillations, for example, from a drive train of a vehicle to an actuator system for a clutch. The oscillation decoupling system has an adjusting element. The actuator system includes an active element which is designed to carry out an active movement in a predetermined working direction and an element of the oscillation decoupling system which connects the active element to the actuator device and to the adjusting element. The element of the oscillation decoupling system includes, in a predetermined direction of work, a play region in which the active element or the adjusting element moves without the respective other moving element.

A locking lever includes: a pair of lever pieces connected to each other to be relatively rotatable; and a spring member which extends about rotating axes of the lever pieces, of which both end portions engage with the lever pieces, and thereby, which biases the lever pieces to rotate in opposite directions, wherein contact portions, which come into contact with each other based on a biasing force of the spring member and thereby, are able to hold relatively rotating positions of the lever pieces, are provided in the lever pieces, respectively, wherein the spring member has spring end portions extending in a radial direction of the rotating shaft, and wherein an engagement surface with which the spring end portion comes into contact in a circumferential direction of the rotating shaft is provided on at least one of the lever pieces.

Systems and methods for aligning a transfer head assembly with a substrate are disclosed. In an embodiment a pivot mount is used for generating a feedback signal in a closed-loop motion control system. In an embodiment, the pivot mount includes a plurality of spring arms, with each spring arm including a switch-back along an axial length of the spring arm such that a pair of first and second lengths of the spring arm are immediately adjacent the switch-back and are parallel to each other. A first strain sensing element is located at the first length, and a second strain sensing element is located at the second length.

An accelerator pedal unit is known comprising an accelerator pedal, an actuator, and a control shaft via which the actuator can transmit a restoring torque to the accelerator pedal. The accelerator pedal unit can generate an additional restoring force which acts on the accelerator pedal, for example in order to regulate or limit the speed of a vehicle or to function as a warning device in the event of speeding. In the accelerator pedal unit according to the invention, the actuator is mechanically decoupled from the accelerator pedal. According to the invention, the torque of the control shaft (3) is transmitted to the accelerator pedal (1) via a damping element (10).

A bicycle operating apparatus is provided with a base member, a ratchet, a pawl member and an operating member. The ratchet is rotatably disposed around a ratchet axis, and biased in a first direction about the ratchet axis. The operating member moves the pawl member from a first position to a second position. The pawl member has a pawl portion and first and second support portions. The pawl portion engages with the ratchet teeth while the pawl member is in the second position to regulate rotation of the ratchet in the first direction. The first support portion pivotally supports the pawl member around a first axis as the pawl member moves from the first position to the second position. The second support portion pivotally supports the pawl member around a second axis while the pawl member is in the second position.
