An assembly for a turbine engine is provided that includes a combustor wall, which includes an aperture body between a shell and a heat shield. The aperture body at least partially forms a cavity and an aperture that extends through the combustor wall. An inlet passage extends in the combustor wall to the cavity. An outlet passage extends in the combustor wall from the cavity to the aperture.

A bearing housing may comprise a cylindrical body and a groove formed in an inner surface of the cylindrical body. The groove may be configured to interface with a bearing. A tapered surface may be formed on an outer diameter of the cylindrical body. A wear plate may be disposed over the tapered surface. An elastic material may be between the tapered surface and the wear plate. The tapered surface may be conical. A length of the tapered surface may be less than half the length of the bearing housing. The tapered surface may be tapered at an angle based on a deflection angle of the piston. A second tapered surface may be formed on the outer diameter of the cylindrical body. An elastic material may be between the second tapered surface and the wear plate.

A hydro dynamic bearing device comprising an upper half of a main bearing and a lower half of the main bearing, wherein the upper half of the main bearing is lined with a low-strength metal such as a Babbitt metal, wherein a circumferential groove is formed in the lower half of the main bearing, and wherein the low-strength metal of the upper half of the main bearing, which is formed at a region opposed to a downstream side of the circumferential groove formed in the lower half of the main bearing, is partially removed to cause a high-strength bearing base metal to be partially exposed.

A bearing component has a first structural component and a second structural component and supports a transverse leaf spring. The first structural component and the second structural component are connected with each other in a hinge-like fashion for rotation and surrounded by a sleeve. The first structural component has a hinge head which is positively held in a hinge head receptacle of the second structural component. The sleeve has a bellow section and protects the structural components of the bearing component from contamination.

A sliding plate hinge of a portable electronic device terminal includes a fixed plate and a sliding plate. A sliding-guide groove for the sliding plate is disposed at either side of the fixed plate. A frictional component supported by an elastic component is also disposed at either side of the fixed plate respectively. The frictional components at the two sides form a compression fit with the side surface of the sliding plate or with the side surface of a component fixedly connected to the sliding plate, so as to generate side pressure against the sliding plate or the component fixedly connected to the sliding plate. The design utilizes the frictional components to generate side pressure against the sliding plate or the component fixedly connected to the sliding plate and thus generate frictional damping, ensuring that the sliding plate hinge has a comfortable hand-feel even in the absence of a drive spring.

Systems and methods are described for providing magnetic biasing of a carriage in context of linear guides. In one embodiment, a robotic mechanism is configured to travel on a platform assembly within a structural context. The platform assembly transports a carriage in a Z direction, and the carriage transports the robotic mechanism in an X direction. The carriage moves in the X direction along rails (e.g., and/or other types of linear guides) in a substantially floating or unbiased manner. For example, one or more alignment features on the carriage are in communication with the rails to allow the carriage to move relatively freely within an alignment region defined by the alignment features. When the carriage reaches its desired X location, magnetic features bias the carriage into a substantially accurate, secure, and repeatable position.

A linear-reciprocating device 10 has a moving block 13 which is attached to a guide rail 12 provided to a support base 11 so as to freely reciprocate, ball rolling grooves 23a and 23b which form ball rolling paths 24a and 24b together with ball rolling grooves 21a and 21b are provided to a base end of the moving block 13, and ball circulation holes 25a and 25b which are communicated to the ball rolling paths 24a and 24b are provided to a base end. In a longitudinal-directional middle area of the moving block 13, return blocks 32a and 32b which communicate between the ball rolling paths 24a and 24b and the ball circulation holes 25a and 25b are provided. The moving block 13 moves to a position at which the moving block 13 is moved to a position at which the moving block is protruded from a distal end of the guide rail 12.
