Abstract: A synchronous movement-aid device for slide module includes at least one aid device. The aid device includes a first arm, a second arm connected with the first arm and a rotational wheel connected with the second arm and rotatable with the movement of the second arm. The first arm has a pivoted end mounted on a rail. When an external force is applied to the first arm, the pivoted end can freely move along the rail relative to the second arm. The second arm has a fixed end connected to the rotational wheel. When the first arm moves along the rail, the rotational wheel is driven to rotate so as to achieve better synchronous movement effect than the conventional slide mechanism.

Abstract: A force transmission transmits forces received by three levers to an input gimbal plate having three support points. The input gimbal play may in turn transmit the force to a wrist assembly coupled to a surgical tool. A first gimbal support point is supported by a first lever having a fulcrum with one degree of rotational freedom. Second and third gimbal support points may be supported by second and third levers having fulcrums with two degrees of rotational freedom. These fulcrums may include a first axle coupled to the lever and a second axle that supports the first axle and provides the fulcrum for the supported lever. A spring may draw the second and third levers toward one another. The force transmission may include a parallelogram linkage that includes a rocker link pivotally coupled to the first lever and having a flat surface that supports the first gimbal support point.

Abstract: A relative-rotation synchronous movement-aid device, which has a simple structure and is easy to assemble. The synchronous movement-aid device includes a linking arm and a rotational wheel assembled with the linking arm. The linking arm has a pivoted end and a free end mounted on the rotational wheel. The pivoted end is mounted on a rail. When an external force is applied to the linking arm, the pivoted end can freely move along the rail. The free end serves to make the rotational wheel relatively rotate along with the movement of the linking arm to achieve better synchronous movement effect than the conventional slide mechanism.

Abstract: In a device for controlling an operation of an anti-collision switch, the anti-collision switch is provided in a support close to a guide frame that is provided at at least one of both lateral sides of a table frame, to prevent collision of the table frame that is supported on the table support to be capable of moving in a lengthwise direction. The device includes a first lever coupled to the table support so that at least a portion of the first lever moves in a vertical direction according to deformation of the guide frame, and a second lever pressing the anti-collision switch in a normal state and, when a vertical movement of the first lever deviates from a preset height, being moved up by the first lever to remove pressing of the anti-collision switch and operate the anti-collision switch.

Abstract: A jacking device is provided to push an object for rotation and upward or downward movement. The jacking device includes a combination of a slave arm and a link arm. The slave arm includes a first end capable of producing rotation and linear movement and a second end pivoted to the link arm, The link arm includes a fixation end disposed on a base and a free end. When the first end of the slave arm is received with an action force, the second end of the slave arm is forced to push the link arm for rotation, and the free end of the link arm is forced to motion between a first position and a second position so as to push m object for rotation and upward or downward movement.

Abstract: A rotary shaft device for a sliding module is provided for a movable and rotatable structure. The rotary shaft device includes a seat capable of assembling to the sliding module, a steering arm pivoted to the seat and formed of a rotatable type on the seat, and a tractor pivoted to the steering arm. The tractor is provided with a hand portion, so that the tractor can be attached to a rail and movable thereon by the hand portion.

Abstract: A height adjustable assembly includes features that allow the height of a frame member to be manually adjusted. A locking assembly may be used to fix the position of a linkage member relative to the frame member. The locking assembly includes a locking plate that engages a protruding portion. The locking plate rotates about an axis that is parallel with a longitudinal direction of the locking plate.

Abstract: A slide rotation device includes a rail portion that is provided along a sliding direction of an upper case, a slide mechanism that has a slide assistance plate sliding the upper case along the rail portion of the upper case, and a rotation mechanism that is provided to be fixed in the vicinity of one end portion of a lower case and rotatably supports the slide assistance plate using a rotation shaft positioned in an extending direction of the slide assistance plate.

Abstract: Disclosed is an arrangement comprising a winch that is preferably used for hoisting loads as well as an adjusting mechanism for the winch. In the assembled state, the winch is mounted on a crane boom so as to be movable by a limited degree between an operating position and a transported position by means of the adjusting mechanism. The adjusting mechanism is equipped with at least one linear drive unit which cooperates with a lever gear to adjust the winch.

Abstract: In a hydraulic tensioner, a deairing valve unit comprising a synthetic resin ball guide, a check ball a biasing spring, a ball seat, and a retaining disc, is press-fit into a hollow plunger, and disposed adjacent the protruding end of the plunger. The ball and seat of the deairing valve unit are arranged to block flow of oil out of the tensioner when the oil is under pressure, but open to allow air to flow out of the tensioner, through a vent in the protruding end of the plunger, after a negative pressure condition occurs inside the oil chamber of the tensioner.

Abstract: An exercising machine having improved control permitting either an assist or a resistance of the exercise being performed comprises a first member exercisingly movable by a part of the body against the resistance of a weight or spring and a second member operable by another part of the body with the second member advantageously comprising a pivotable lever, with a linkage selectively engageable between the second member and the weight or spring in two modes in which force applied to the second member in the same direction respectively assists and resists movement of the first member.

Abstract: At an extremity of the pointer board of a push-button tuner is fixed a member on which a pointer is mounted. At a surface of the member on which the pointer is mounted. There is disposed a lateral fitting groove having an opening at the front surface. The fitting groove is provided with indentations. The pointer has a fitting portion engaging with the fitting groove on its back surface and the fitting portion has protrusion engaging with one of the indentations.

Abstract: Dumping apparatus is illustrated wherein a novel compound linkage system is employed in which a first link is pivoted to move a receptacle and the like as to be dumped to an intermediate position and thereafter through movement of a second link the receptacle is raised to dumping position, but only after a latch mechanism to positively position the receptacle is secured through a novel lost motion coupling.

Abstract: A holding apparatus for use in combination with a working machine, where such loading apparatus has a first quadric parallel link body attached to the working machine and adapted to be oscillated within a vertical plane; a second quadric parallel link body attached to the first link body through a L-shaped member for oscillating motion therewith, and having a holder arm assembly effective to hold a workpiece; and a mechanism adapted to reciprocate said holder arm assembly of the second link body.
