A device for shearing tissue in a human or animal body may include a first member made of a first material and a second member made of a second material. A thread is connected to the first member and to the second member, and the first and second materials show magnetic attraction between one another. A means is provided for pulling the thread between the first and second members.

An object of the present invention is to provide a tensioner that has a reduced number of components and weight, and is easy to assemble. The tensioner has a base member loosely fitted into an open rear end of a cylindrical plunger with a closed front end against the resiliency of a biasing means accommodated inside the plunger. The tensioner includes a plunger stopper mechanism configured such that an engaging part formed on the base member detachably engages an engaging groove provided on an inner circumferential surface of the plunger directly or via another member.

Provided herein is an auxiliary hybrid system (AHS) that may be configured to provide electrical propulsion to an e.g., internal combustion-powered vehicle through the use of a battery and electric motor. Alternatively, the AHS may be configured to increase range to electric vehicles through the use of an internal combustion-powered generator. In either embodiment, the AHS is added to a vehicle without altering the operation of the vehicles standard drivetrain, allowing the vehicle to operate conventionally when the AHS is not engaged. The AHS is compatible with a wide range of vehicles with a minimum of vehicle-specific parts.

A belt tension adjustment device includes a driving pulley attached to a power transmission shaft, a driven pulley arranged in a driven device, a tension pulley, a loop belt arranged between the driving pulley, the driven pulley, and the tension pulley, and configured to transmit a rotational driving force of the power transmission shaft to the driven device, and a tension adjustment mechanism to adjust tension of the loop belt. The tension adjustment mechanism includes a support shaft rotatably supported, a rotational operation mechanism to rotate the support shaft about an axis of the support shaft, and a rotating member coupling the support shaft and the tension pulley, configured to change a relative position of the tension pulley with respect to the driving pulley and the driven pulley in accordance with rotating of the support shaft.

An orbital tensioner comprising an annular base, a ring journalled to the annular base on a ball bearing, said ring having a ring axis of rotation (A-A), a first pulley journalled to the ring, a first pulley axis of rotation (B-B) offset from the ring axis of rotation (A-A), a pivot arm pivotally mounted to the ring, a pivot arm pivot axis (C-C) offset from the ring axis of rotation (A-A), a second pulley journalled to the pivot arm, a torsion spring biasing the pivot arm in a first direction, the ball bearing having a first race and a second race, the ring fixed to the first race, the annular base fixed to the second race, and a damping mechanism frictionally disposed between the ring and the base.

A pulley device for a tensioner roller or winding roller of a transmission element, providing a pulley, and a bearing. The bearing includes a rotating outer ring mounted to the pulley, a fixed inner ring, and at least one row of rolling elements arranged between the rings. The inner ring of the bearing has at least one end portion protruding axially with respect to the outer ring. The pulley is provided with at least one pulley element that is C-shaped in axial section. One of the at least one pulley elements is provided with a lateral portion extending substantially radially to pass into the immediate vicinity of an outer surface of the axially protruding end portion of the inner ring.
