A surgical stapling and severing instrument particularly suited to endoscopic procedures incorporates a handle that produces separate closing and firing motions to actuate an end effector. In particular, the handle produces multiple firing strokes in order to reduce the required amount of force required to fire (i.e., staple and sever) the end effector. A linked transmission reduces the required handle longitudinal length, yet achieves a rigid, strong configuration when straightened for firing. A traction biased firing mechanism avoids binding in driving this straightened linked rack in cooperation with an anti-backup mechanism, with a lockout mechanism that prevents releasing the closure trigger during firing. Furthermore, an external indicator gives feedback to the surgeon as to how far firing has progressed, as well as providing a manual retraction capability.

Provided are a multi-channel semiconductor device and a method for manufacturing the semiconductor device through a simplified process. A sacrificial layer and a channel layer are alternately stacked on a semiconductor substrate. Thereafter, the sacrificial layer and the channel layer are etched to form a separated active pattern, and a device isolation layer is formed to cover sidewalls of the active pattern. Dopant ions are implanted into the entire semiconductor substrate, thereby forming a channel separation region under the active pattern. A portion of the active pattern is etched to separate the active pattern from a pair of facing sidewalls of the device separation layer, thereby forming a channel pattern having a pair of first exposed sidewalls. Source / drain semiconductor layers are formed on the first sidewalls of the channel pattern, and a part of the device isolation layer is removed to expose a pair of second sidewalls of the channel pattern contacting with the device separation layer. Thereafter, the sacrificial layer included in the channel pattern is remove, and a conductive layer for a gate electrode is formed to cover the channel layer exposed by the removing of the sacrificial layer.

A coarse jaw adjustment sleeve formed of a short section of hollow steel tubing is coaxially disposed about an outboard support member in sliding engagement therewith. The coarse adjustment sleeve has one or more perforations therethrough so that a locking pin can be passed through it and through aligned openings in the outboard support member. A fine adjustment screw member is disposed coaxially within a vertical rail support tube and may be rotated by lever arms to move the upper jaw closer to or further from the lower jaw. Adjustment of the fine positioning mechanism is performed by manipulating handles at the top of the vertical rail support tube. A workman installing the stanchion thereby does not have to stoop over to operate a clamp located down near the concrete slab.

Aspects of the invention are directed to an acoustic resonator with improved impingement cooling effectiveness. The resonator includes a plate with an inside face and an outside face. A plurality of passages extend through the plate. The resonator includes a side wall that extends from and about the plate. A plurality of cooling tubes are attached to the resonator plate such that an inner passage of each cooling tube is in fluid communication with a respective passage in the resonator plate. The resonator can be secured to a surface of a turbine engine combustor component to define a closed cavity. The ends of the cooling tubes are spaced from the surface. Thus, a coolant can enter the passages in the plate and can be directed to the surface so as to impingement cool the surface. The cooling tubes can minimize coolant loss by dispersion in the cavity.

When the safety barricade is in its second position, the net is extended from housing to span the area between first and second supports, substantially covering the opening between the supports and blocking passage through the area. Operation of the device is performed by a single user, who manually extends or retracts the net barrier using the pull bar.

A modular fence system. The system includes fence planks designed for insertion into open channels of upper and lower fence rails. The fence rails are supported in a horizontal orientation between intermittent fence posts, with the fence planks extending vertically between the rails. The planks include resilient protrusions, called plank-projections, at their upper ends. The plank-projections are designed to engage with channel-projections formed in the open channels of the upper fence rail and lower fence rail, to inhibit inadvertent removal of the planks from the upper rail. Alternatively, the plank-projections may be eliminated in favor of having the channel-projections simply grip the planks frictionally, or, vice versa, the channel-projections could be eliminated in favor of having the plank-projections press frictionally against the walls of the open channels in the upper rail or lower rail or both. Accordingly, the engagement between the upper rail and the planks takes some weight off the lower rail such that fewer support posts are needed, and that engagement can be provided with just the channel-projections, or just the plank-projections, or both.

This facilitates packing and shipping of the units and mitigates against damage to the units. The units are dimensioned and sized to be stronger, more damage resistant, more versatile and more user-friendly than conventional edger bricks or tiles. A process of making the edger units is also disclosed.

A cooled acoustic liner useful in a fluid handling duct includes a resonator chamber 52 with a neck 56, a face sheet 86, and a coolant plenum 80 residing between the face sheet and the chamber. Coolant bypasses the resonator chamber, rather than flowing through it, resulting in better acoustic admittance than in liners in which coolant flows through the resonator chamber and neck. In one embodiment, the liner also includes a graze shield 88. Openings 40, 38 penetrate both the face sheet and the shield to establish a relatively low face sheet porosity and a relatively high shield porosity. The shielded embodiment of the invention helps prevent a loss of acoustic admittance due to fluid grazing past the liner. Another embodiment that is not necessarily cooled, includes the resonator chamber, low porosity face sheet and high porosity shield, but no coolant plenum for bypassing coolant around the resonator chamber. An associated method of retrofitting an acoustic treatment into a fluid handling module includes installing openings in the module and mounting a resonator box 44 on the module so that the inlets to the resonator necks register with the installed openings.
