An actuator is provided. The actuator includes a housing and a ram linearly movable relative to the housing. The ram is selectively mechanically coupled to a drive screw of the actuator such that in one configuration, the ram is decoupled from the drive screw to allow it to linearly move independently from rotation of the drive screw.

The present invention provides a rack assist type electric power steering apparatus. The power steering apparatus includes: a ball nut coupled to a rack bar via balls to be rotated, and configured to cause the rack bar to slide; a bearing mounted on an outer peripheral surface of the ball nut so as to support rotation of the ball nut; and a support member coupled to at least one of a space between one side of an outer race of the bearing and a housing and a space between the other side of the outer race of the bearing and the housing so as to support the bearing.

A vehicle includes a prime mover in communication with an input shaft of a transmission, an output shaft of the transmission in communication with a final drive and drive wheels, a park actuator system internal to a housing of the transmission and a park control system mounted to an external surface of the housing of the transmission with a pivot shaft extending through the housing that connects to the park actuator system to selectively place the park actuator system in one of a park configuration and an out of park configuration.

A water environment robotic system and method has a buoyancy configuration which can be selectively altered. The system includes an underwater robotic vehicle and a buoyancy module that is configured to be selectively buoyantly engaged and buoyantly disengaged with the underwater robotic vehicle. A tether is connected to the buoyancy module and a motor is operatively connected to the tether and is configured to extend and retract the tether and buoyancy module. The tether can be extended and retracted to extend and retract the buoyancy module. Extending and retracting the buoyancy module can buoyantly engage or buoyantly disengage the buoyancy module with the underwater robotic vehicle according to the arrangement of the system. By engaging and disengaging the buoyancy module, the buoyancy of the underwater robot can be selectively altered.

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.

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.
