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 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.
