Disclosed herein is a bearing assembly for a vehicle steering apparatus, which includes a bearing including an inner ring fastened to a rack bar, an outer ring disposed outside the inner ring with a ball interposed therebetween, and a sealing member provided between the inner ring and the outer ring, and an elastic clip including a body pressed against an outer peripheral surface of the outer ring, fastening portions bent toward sides of the outer ring from both ends of the body, and elastic portions extending from respective ends of the fastening portions and protruding laterally of the outer ring to each have a curvature.

An actuator device includes a cartwheel flexure having a central moving carriage component configured for parallel motion along an axis of the actuator device. A frame is configured to remain stationary relative to the central moving carriage component. A plurality of cross-beams flexibly support the central moving carriage from the frame, wherein the plurality of cross-beams provide flexibility for movement of the central moving carriage relative to the frame along the axis and provide rigidity in other directions.

A turning apparatus (30) includes an electric motor (41), a moving gear (53) that is movable between a first position at which rotation of an output shaft (43) of the electric motor (41) is able to be transmitted to a rotor (11), and a second position and a third position, which are different from each other and at which rotation of the output shaft (43) is unable to be transmitted to the rotor (11), a movement mechanism (60) configured to move the moving gear (53) between the first position, the second position and the third position, and a control device (61) configured to control the movement mechanism (60) based on a. retreat signal such that the moving gear (53) is moved from the first position to the second position and control the movement mechanism (60) based on an adhesion prevention signal such that the moving gear (53) reciprocates between the second position and the third position.

A barring-tool system improving safety, speed, effectiveness, and number of personnel required for maintenance, repair, and inspection of large engines, generators, and turbines, providing controlled bidirectional rotation and locking of crankshafts during maintenance, and a method for maintenance of large engines, generators, and turbines using the barring-tool system.

A projector is attached to an opening provided in an installation surface and projects an image to one side with respect to the installation surface. The projector includes: an exterior panel exposed on the one side; a projection section that projects image light from a projection port formed in the exterior panel to the one side; and a rotation adjustment mechanism and an inclination adjustment mechanism that adjust a posture of the projection section with respect to the installation surface.

Linear actuator system comprising a linear actuator and at least one box, such as a control box containing a control and possibly also a mains-based power supply or a battery box with a rechargeable battery pack. The linear actuator system further comprises a fastening means for the box, wherein the fastening means is constituted by an elongated item with a rectangular outline and a square cross-section. The box has a groove for receiving the fastening means. The fastening means and the groove are constituted with mutually interacting releasable locking connections. The fastening means can be designed as an independent item that can be fastened where the box is to be placed. The fastening means can also be used to interconnect two or more boxes by fastening the fastening means to a box. Alternatively, the fastening means can be formed as an integral part of the box. The fastening means can also be used to fasten a box to the outer tube on a linear actuator by fastening or, more expediently, by the fastening means being designed as an integral part of a tubular mounting bracket which is slid over an outer tube on the linear actuator.

A drive apparatus according to an embodiment includes a first rotation unit, a base, a lead screw unit, and a second rotation unit. The first rotation unit includes a gear rotatable in first directions by a drive power source. The base is joined to the gear and is rotatable in the first directions with the gear. The lead screw unit is provided to the base and moves a shaft back and forth in a certain direction. The second rotation unit is pivotally supported by the base, rotates in second directions different from the first directions, and supports a certain supported member rotatably in the second directions.

A centrifugal force converting apparatus and a method for converting centrifugal force to a unidirectional force. The centrifugal force converting apparatus may include a curvilinear, variable-radius continuous track along which a roller is urged to traverse during rotation of a vertical shaft; a displaceable platform connected to the track; a linear guide connected to the shaft along which a single weighted carriage connected to the roller is slidable; and a speed controller for controllably varying rotational speed of the shaft.
