A lamina emergent torsional (LET) joint that includes an integrated membrane to reduce, or eliminate, certain unwanted motions and/or displacements associated with the operation of the LET joint is disclosed. The membrane-integrated LET joint (i.e., M-LET) can be used as a hinge for a lamina emergent mechanism and/or as a surrogate fold for an origami application to ensure accurate and repeatable transitions from a planar (i.e., lamina) state to a non-planar (i.e., lamina-emergent) state, and vice versa.

A spring for use in conjunction with a vehicle, in particular a leaf spring (1), preferably a parabolic spring, has a single-part spring leaf (12) made of steel, in particular spring steel, having a central region (2) and two adjoining edge regions (4a, 4b), wherein the edge regions (4a, 4b) each have an end region (5a, 5b), the end regions (5a, 5b) can each be connected to a chassis in a stationary manner via a rolled eye (11), and the total length of the spring when installed on the vehicle is substantially unchangeable in all load states. In the unloaded state, the spring leaf (12) has two bending sections (13, 14), which each have a curvature with a curvature direction, wherein the curvature directions of the two bending sections (13, 14) are opposed, and the two bending sections (13, 14) merge into each other in the region of a turning point (15). The first bending section (13) is a vertical spring section and runs from the end region (5a) of the first edge region (4a) via the central region (2) to the turning point (15). The second bending section (14) is a horizontal and vertical spring section and runs from the turning point (15) to the end region (5b) of the second edge region (4b).

A damping-force generation mechanism includes: a first flow path forming portion forming a flow path in which a fluid flows; a first valve configured to control a flow of the fluid in the flow path; a back pressure chamber forming portion forming a back pressure chamber configured to apply a back pressure to the first valve; a second flow path forming portion including a plurality of connection flow paths connected to the back pressure chamber; and a second valve provided to face the second flow path forming portion and configured to control flows of the fluid in the plurality of connection flow paths.

A damping force generating mechanism includes: a flow passage formation part that forms a flow passage through which a liquid flows; a valve configured to control a flow of the liquid in the flow passage; a back pressure control valve configured to control a pressure in a back pressure chamber that provides a back pressure to the valve by inflow of the liquid; and an accommodation part that is in a tubular shape with one side opening end narrower than another side opening end, forms the back pressure chamber, and accommodates at least the valve and the back pressure control valve.

A camera lens suspension assembly includes a support member including a support metal base layer, a moving member including a moving metal base layer, bearings and smart memory alloy wires. The support member includes a bearing plate portion, static wire attach structures, and mount regions. A printed circuit on the support metal base layer includes traces extending to each static wire attach structure. The moving member includes a moving plate portion, elongated flexure arms extending from a periphery of the moving plate portion and including mount regions on ends opposite the moving plate portion, and moving wire attach structures. The bearings are between and engage the bearing plate portion of the support member and the moving plate portion of the moving member. Each of the smart memory alloy wires is attached to and extends one of the static wire attach structures and one of the moving wire attach structures.

A damping force generating mechanism includes: a flow passage formation part that forms a flow passage through which a liquid flows; and a valve that is configured to control a flow of the liquid in the flow passage. The flow passage formation part includes a first seat part that is provided radially outward of a flow passage port of the flow passage, protrudes from the flow passage port and contacts the valve, a second seat part that is provided radially outward of the first seat part, protrudes from the flow passage port and contacts the valve, and a circulation part having an orifice that allows the liquid to flow from the flow passage port toward the second seat part in a state in which the valve is in contact with the first seat part.

A compressor is provided. The compressor compressing and discharging a refrigerant sucked into a cylinder comprises the cylinder configured to form a compressed space of the refrigerant and having a cylindrical shape; a piston configured to reciprocate axially in the cylinder and having a cylindrical shape; an intake valve disposed at a front of the piston; a fixing member disposed outside the piston; a rod comprising one end disposed at the intake valve and configured to extend axially; a first elastic member connected to the fixing member and other side of the rod; a second elastic member disposed to be spaced apart from a rear of the first elastic member and connected to the fixing member and the other side of the rod; and a first spacer insert-injected with the first elastic member and the second elastic member.

A fuel supply device includes a pump unit with a fuel pump that has a rotary body rotating about a rotary shaft and a load receiving portion, configured to receive the load of the pump unit. A connecting portion is provided for connecting the pump unit to the load receiving portion such that the pump unit is suspended by the load receiving portion. The connecting portion is disposed so as to extend across a virtual plane which is perpendicular to the rotary shaft for the rotary body of the fuel pump and passes through the center of gravity of the pump unit.
