To reduce energy loss to increase power transmission efficiency, as well as to suppress unusual sound resulting from whirling vibration. A driving force transmission mechanism includes a drive unit that generates a rotation force and consists of a motor, as well as an independent rotating mechanism that is disposed between the drive unit and one of a pair of left and right gear mechanisms so as to be connected to the output shaft of the drive unit and has greater kinetic energy than the rotating parts of the gear mechanisms. Flexible shafts that rotate by smaller kinetic energy than any of the kinetic energy of the drive unit, the kinetic energy of the rotating mechanism, and the friction forces and damping forces of the rotating parts of the gear mechanisms connect between the drive unit and rotating mechanism, between the rotating mechanism and one gear mechanism, and between the drive unit and the other gear mechanism.

To prevent creation of unnecessary resin when fixing a magnet with resin, a manufacturing method for manufacturing a magnet embedded core comprises: a placing step of placing the rotor core on a mounting table such that an end surface of the rotor core is in contact with the mounting table; a resin charging step of charging the resin in solid state into the magnet insertion hole; a melting step of inciting the resin in the magnet insertion hole; a magnet inserting step of inserting the magnet into the magnet insertion hole; a closure step of closing the opening of the magnet insertion hole remote from the mounting table; and a resin pressurizing step of pressurizing the molten resin that has flowed into a buffer chamber formed in the mounting table from the opening of the magnet insertion hole on a side of the mounting table following the closure step.

Apparatuses and methods of operating a linear differential (100, 600) are described herein. The linear differential (100, 600) contains a slide portion (102) with parallel right-hand and left-hand threaded rods (112, 114). Threaded onto the right-hand and left-hand threaded rods (112, 114) and attached to the slide portion (102) are right-hand and left-hand gears (116, 118). Meshed between the right-hand and left-hand gears (116, 118) and also attached to the slide portion (102) is a driven gear (200). An end effector (104) is attached to the driven gear (200) and is configured to translate along a translation axis (110) and rotate around a rotation axis (120).

A shower caddy for attachment to an associated outer enclosure panel or door of an associated shower or tub enclosure includes a body and an attachment mechanism mounted on an end portion of the body. The attachment mechanism has at least one movable mounting arm. The attachment mechanism is configured such that downward movement of the body relative to the attachment mechanism by force of gravity moves the at least one mounting arm from a rest position toward an engagement position where the at least one mounting arm is engageable with the associated outer enclosure panel or door.

A linear actuator, which is assembled from a plurality of structurally identical individual actuators, each of which has a housing and an output shaft which is arranged to be longitudinally displaceable in the housing and which penetrates the housing, wherein the housing is designed on its outer surface as a polygonal profile with polygonal sides of equal length, which define outer polygonal surfaces arranged around the output shaft, wherein at least one of the polygonal surfaces of the housing is intended to rest against one of the polygonal surfaces of one of the other housings. The output shafts are coupled to one another by a common coupling element for common adjusting movements and for a parallel connection of the actuating forces acting in the individual actuators.

An electric actuator includes an input member that is rotationally driven by the electric motor and includes a first rotation stop part on an inner periphery, an output member that includes a second rotation stop part engageable with the first rotation stop part, and a first screw part on an outer periphery, and a linear motion member that includes a second screw part engageable with the first screw part. Both the screw mechanism and the rotation-stop mechanism are formed on the outer periphery of the output member. Therefore, in the electric actuator, the radial and axial dimensions are shortened.

A linear actuator comprising a housing with a proximal end and a distal end, and defining a central cavity extending axially; a piston tube at least partially positioned axially within the central cavity; a first elongated rotatable screw positioned axially within the central cavity; a first cylindrical nut mounted about the first elongated rotatable screw and configured to move axially as the first elongated rotatable screw rotates; a second elongated rotatable screw positioned axially within the central cavity; a second cylindrical nut mounted about the second elongated rotatable screw and configured to move axially within the central cavity as the second elongated rotatable screw rotates; and a spring positioned around the second elongated rotatable screw between the second cylindrical nut and the distal end of the housing, wherein the spring is configured to bias the second cylindrical nut away from the distal end of the housing.

A magnet embedded core is manufactured in a stable manner even when using a die clamping device having a large rated clamping force by preventing an excessive pressurizing force from being applied to a laminated iron core, performing the clamping with an appropriate pressurizing force so to minimize leakage of the resin out of magnet insertion holes, and suppressing a reduction in the geometric and dimensional precision of the laminated iron core. A die clamping device for driving a moveable platen in a direction toward and away from a fixed lower platen is configured to include a toggle link mechanism. In a fully extended state of the toggle link mechanism, an upper die abuts an end surface of the laminated iron core to close openings of the magnet insertion holes and pressurize the laminated iron core in a laminating direction.

An actuator comprising first and second motors, first and second drive linkages, and a pivot mount configured to pivot about a pivot axis, the pivot mount connected to the first and second drive linkages at first and second mount connections offset first and second offset distances from the pivot axis, the motors and first and second drive linkages configured to provide first and second load paths between a drive housing and the pivot mount so that in a first operation state the pivot mount is in a force-balanced orientation about the pivot axis, and a proximity detector positioned to detect when the pivot mount rotates about the pivot axis above a threshold out of the force-balanced orientation, wherein a force imbalance on the pivot mount caused by a fault in one of the first or second drive linkages above a threshold is detected by the proximity detector.
