A flat fold filtering face piece respirator 10 that includes a mask body 12 and a harness 14. The mask body 12 includes a filtering structure 16 that contains a cover web 48, 50 and a filtration layer 52 that contains electrically-charged microfibers.

A valve cage device is adapted for use with a subsurface pump or the like. The valve cage includes a housing and an insert. The insert includes a cradle, a plurality of angled ribs, and a base. In one embodiment, the insert may also include an extended nose region. A ball and seat may be positioned in the valve cage. During pumping operations, the cradle retains the ball when the ball is unseated, thereby allowing fluid to pass freely through channels in the insert and around the ball. This eliminates violent action of the ball, thereby obviating a need for a hard liner to be included in the valve cage. A port in the cradle allows fluid to pass therethrough when the ball has been released from the cradle. The angular configuration of the ribs provides for a more laminar flow of fluid compared with prior art valve cages, thereby providing improved passage of fluid through the valve cage. The base may include an angled hook or lip that creates a tight seal, thereby preventing fluid from washing by during pumping operations. During pumping operations, when the ball is released from the cradle, it is guided by the insert and falls straight downward onto the seat, allowing for faster seating of the ball, and in turn, reducing pump stroke loss and providing for more efficient pumping. The valve cage may be configured for a traveling valve or standing valve portion of a subsurface pump or the like.

Improved MOSFET devices are obtained by incorporating strain inducing source-drain regions whose closest facing “nose” portions underlying the gate are located at different depths from the device surface. In a preferred embodiment, the spaced-apart source-drain regions may laterally overlap. This close proximity increases the favorable impact of the strain inducing source-drain regions on the carrier mobility in an induced channel region between the source and drain. The source-drain regions are formed by epitaxially refilling asymmetric cavities etched from both sides of the gate. Cavity asymmetry is obtained by forming an initial cavity proximate only one sidewall of the gate and then etching the final spaced-apart source-drain cavities proximate both sidewalls of the gate along predetermined crystallographic directions. The finished cavities having different depths and nose regions at different heights extending toward each other under the gate, are epitaxially refilled with the strain inducing semiconductor material for the source-drain regions.
