The present invention provides a system and method for actively manipulating and controlling aerodynamic or hydrodynamic flow field vortices within a fluid flow over a surface using micro-jet arrays. The system and method for actively manipulating and controlling the inception point, size and trajectory of flow field vortices within the fluid flow places micro-jet arrays on surfaces bounding the fluid flow. These micro-jet arrays are then actively manipulated to control the flow behavior of the ducted fluid flow, influence the inception point and trajectory of flow field vortices within the fluid flow, and reduce flow separation within the primary fluid flow.

A flexible board includes a base layer, a wiring conductor layer that is located on the base layer, and a cover layer that is stacked over the base layer and covers the wiring conductor layer. A portion of the wiring conductor layer defines connecting portions that connect each of split electrodes of a flexible thermistor. The cover layer includes an opening that exposes the connecting portions, and receives the flexible thermistor. The split electrodes of the flexible thermistor are mounted on the connecting portions of the wiring layer. The height of the exposed surface of the flexible thermistor from the opening is substantially equal to the height of the surface of the cover layer.

A pressure exchanger system having at least two tubular chambers, in which a plurality of reversing valves reverse the flow paths of fluid flows through the at least two tubular chambers. At least one driven reversing valve alternately reverses the flow paths between a supply source, which supplies a high-energy high-pressure fluid, and the tubular chambers. In reversing the liquid flows and shutting off previously open flow paths, the driven reversing element in the reversing valve executes a discontinuous or variable movement sequence.

An electric power steering device (1) is provided which transmits output rotation of an electric motor for generating a steering assist force (16) to a steering mechanism (64) via a driving gear (22) and a driven gear (21). A housing (8) has a support hole (28) for supporting one end portion (23) of a shaft (20) co-rotatable with the driving gear (22) via a bearing (26) in such a manner as to permit the one end portion (23) to be offset toward the driven gear (21) radially of the driving gear (22). A biasing member (33) which biases the driving gear (22) toward the driven gear (21) includes an arcuate main portion (47) fitted around an outer peripheral surface (58) of an outer ring (36) of the bearing (26) and opposed to an inner peripheral surface (42) of the support hole (28). A pair of movement restriction portions (50, 51) which restrict circumferential movement of the main portion (47) are respectively provided at a pair of arc ends (48, 49) of the main portion (47). A resilient tongue (52) which biases the driving gear (22) toward the driven gear (21) via the bearing (26) is provided only on one of the movement restriction portions (50).

A multistage gear pump assembly includes first and second gear pumps that use common shafts and are axially separated by a fixed spacer within the housing. Pressurized bearings are provided at opposite axial ends of the first and second gear pumps. The second gear pump handles cruise and idle operations of the aircraft while the first gear pump stage assists in meeting higher demand modes of engine operation. Otherwise, the first gear pump is maintained at a minimal pressure to reduce energy consumption and still provide desired stability and eliminate issues associated with bearing oil whirl associated with prior known arrangements. When additional assistance is required, such as during takeoff, climb, or windmill relight, the first gear pump advantageously contributes to the increased pressure.

The invention relates to a method for introducing and removing workpieces, especially vehicle bodies, into or from a treatment area (20) by rotational movements, whereby the treatment area serves for treating surfaces of the workpieces (1). A workpiece (1) is detachably fixed at a holding frame (2) which is moved together with at least one workpiece that is situated thereon at an essentially constant speed and by a continuous translation. The workpiece (1) is rotated around a rotational axle (6) at least at the beginning and end of the treatment area (20) and simultaneously with the translation movement. The rotational axle (6) is orientated vertically in relation to the moving direction of the holding frame (2) and is lifted and lowered during rotation.

In a metallization system of a sophisticated semiconductor device, metal pillars may be provided so as to exhibit an increased efficiency in distributing any mechanical stress exerted thereon. This may be accomplished by significantly increasing the surface area of the final passivation layer that is in tight mechanical contact with the metal pillar.

A valve includes a housing, a rotational body, two seat rings, a shaft integrally linked to the rotational body, and a sealing element. The rotational body is arranged rotatably in the housing and has a through-opening. The seat rings are spaced apart in the housing, each positioned against an outer surface of the rotational body to seal against leakage. The shaft extends outwardly through a housing opening.

A flow path is defined by a housing through-opening and a rotational body through-opening, and is closed or at least partially open as determined by a rotational angle position of the rotational body about a rotational axis. The rotational body and shaft move together pivoting about a pivot axis that is orthogonal to the rotational axis. The pivot axis is determined by the shaft part's spherical outer surface.
