A device for creating more natural three-dimensional image effects which may be recorded, for example, by video cameras. The device has an intermittent image pathway occluder for receiving at least two image pathways which alternately and intermittently occludes the two image pathways, a horizontal imaging-shifting component for shifting at least one of the image pathways leftward or rightward, a vertical imaging-shifting component for shifting the image pathways upward and downward, and an image pathway compositing component which forms a coincident superimposed composite three-dimensional image after the image pathways have been shifted by the horizontal and vertical imaging-shifting components, and after passing through the intermittent image pathway occluder. Also, a device for enhancing the more natural three-dimensional effect of such images which are created and which may be recorded and/or displayed.

A gear device includes a first gear, a second gear, and a third gear. The second gear is constituted of first meshing teeth that mesh with teeth in a first row of teeth of the first gear, second meshing teeth that mesh with teeth in a second row of teeth of the first gear, third meshing teeth that mesh with teeth in a third row of teeth of the third gear, and fourth meshing teeth that mesh with teeth in a fourth row of teeth of the third gear. The helix directions of the first meshing teeth and the third meshing teeth are the same direction. The helix directions of the second meshing teeth and the fourth meshing teeth are the same direction.

A two piece pulley is provided in which the pulley main housing and the outer pulley shell are molded without the bearing in place, thus eliminating an over-molding process. The pulley main housing is molded with a bear slip fit pocket. At least one of the bearing races of the bearing assembly includes an axially-protruding raised surface such as knurls or bumps. Each of the pulley main housing and the outer shell includes a bearing shield. On assembly, the bearing is slipped into the pocket on the pulley main housing and the outer shell is then ultrasonically welded to the main housing, thereby compressing the pulley material axially into the raised surface of the bearing race, locking the outer race of the bearing to the pulley in an axial direction. The raised surface on the bearing race allows the bearing assembly to grip the pulley in an axial direction.

A cycloidal gear pair reducer including an input shaft, mounted in a reducer casing such that it rotates about an axis referred to as main axis, an eccentric member carried by the input shaft and rotated by the latter, at least one cycloidal disc rotatably mounted on the eccentric member and having a cycloidal toothing, at least one ring gear provided with a receiving toothing with which the cycloidal toothing of the cycloidal disc meshes, and an output shaft; wherein the reducer comprises a suspension device arranged to return elastically the cycloidal toothing of the cycloidal disc and the receiving toothing of the ring gear towards one another such that the meshing backlash between the cycloidal disc and the ring gear is self-adjusted along at least one radial component relative to the main axis.

A slide member (26) is externally fitted to an outer peripheral surface of an outer ring (20) configuring a tip side bearing (9a) for supporting a tip portion of a worm shaft (6a) so as to be displaceable in an axial direction. A first inclined cylindrical face portion (32) which is an inclined surface disposed on an outer peripheral surface of the slide member (26), and a second inclined cylindrical face portion (30) which is an inclined surface disposed on an inner peripheral surface of a guide member (28) internally fitted and fixed to a holding hole (10a) of a housing (3a) are fitted to each other so as to be slidable in an inclined direction of the respective inclined cylindrical face portions (32, 30). An elastic ring (29) which biases a bearing holding member (26) against to one side in the axial direction is disposed. This realizes a structure which can shorten an axial dimension of a tip side portion of the worm shaft in an electric power steering device including biasing means for minimizing backlash in a meshing portion of a worm reduction gear.

An actuation mechanism for a valve comprises a first member having a generally spherical surface on a first side of a bisecting line and a generally ellipsoidal surface on a second side of the bisecting line. The first member is rotatable around a central point of the bisecting line. The valve has a second member with a truncated ellipsoidal surface on both sides of a bisecting line. The second member matingly engages the first member at the first member ellipsoidal surface. The valve also includes a longitudinal member coupled to the second member and a biasing member coupled to the longitudinal member. The first member is rotated around the central point from a first position to a second position to move the second member and the longitudinal member linearly. The biasing member returns the first member and second member to the first position upon release of the first member.

A belt drive system comprising a belt having a plurality of longitudinally spaced belt teeth, the belt further comprising a longitudinal groove extending in the endless direction of the belt through the belt teeth, a sprocket comprising a plurality of sprocket teeth on an outer circumference of the sprocket, each of the sprocket teeth extending parallel to the rotation axis, and each sprocket tooth configured to be received between adjacent belt teeth, and a first planar fin extending from at least one side of a sprocket tooth, the first planar fin configured to cooperatively engage the longitudinal groove, the first planar fin extending in a direction normal to a sprocket axis of rotation, the first planar fin having a width no greater than 20% of a sprocket groove width (W).

A gear arrangement with a divided spur toothing includes a main gear and a gear rotatable to the latter in a circumferential direction. The main gear has a hub on which the rotatable gear is arranged. A spring element is arranged between the main gear and the rotatable gear. With the spring element, the rotatable gear is pretensioned in the circumferential direction against the main gear. A first spur toothing part of the spur toothing is formed on the main gear and a second spur toothing part of the spur toothing is formed on the rotatable gear. The first spur toothing part has a first axis of rotation and the second spur toothing part has a second axis of rotation. The second axis of rotation of the second spur toothing part is offset relative to the first axis of rotation of the first spur toothing part.

A conveyor pulley design incorporates a plow design that forces tramp material away from the belt and discharges material down and away from the belt, bearings, take-up assembly, maintenance equipment and personnel. The pulley uses a modular construction that allows for optimized manufacture and inventory processes and reduces the materials cost in the pulley.

A belt drive system comprising a belt having a plurality of longitudinally spaced belt teeth, the belt further comprising a longitudinal groove extending in the endless direction of the belt through the belt teeth, a sprocket comprising a plurality of sprocket teeth on an outer circumference of the sprocket, each of the sprocket teeth extending parallel to the rotation axis, and each sprocket tooth configured to be received between adjacent belt teeth, and a first planar fin extending from at least one side of a sprocket tooth, the first planar fin configured to cooperatively engage the longitudinal groove, the first planar fin extending in a direction normal to a sprocket axis of rotation, the first planar fin having a width no greater than 20% of a sprocket groove width (W).
