摘要:
A loudspeaker enclosure of the acoustic suspension type has a hollow interior of a generally spherical shape, and the enclosure is formed of polyurethane foamed plastic in which the volume (V) of the enclosure interior is determined according to the following empirical formula:V=[MD].sup.3where M is the distance between the limits of mechanical excursion of a given loudspeaker mounted in an aperture in the enclosure as the diaphragm of the speaker is moved under a constant mechanical force, and D is the diameter of the loudspeaker.

The invention is a gap accessary device for elevated roller rails disposed on a platform floor. The device includes a housing, fingers, tangs, roller support structures, rollers, a first curved truncated inclined plane, and a second curved truncated inclined plane. The device allows cargo to enter a platform without catching on the platform threshold and requires less effort to load cargo onto a platform with elevated roller rails.

Methods of forming a strained channel device utilizing dislocations disposed in source/drain structures are described. Those methods and structures may include forming a thin silicon germanium material in a source/drain opening of a device comprising silicon, wherein multiple dislocations are formed in the silicon germanium material. A source/drain material may be formed on the thin silicon germanium material, wherein the dislocations induce a tensile strain in a channel region of the device.

Embodiments of the present invention are directed to a devices and methods for forming a desired miture of two or more fluids in a conduit. The devices and methods feature control means having error monitoring means and in response to an error event the control means organizes the packet-group of command signals to form at least one first error packet group. The error event occurs during the period of time in which the at least one error packet-group is received by a selectable value. The at least one error packet-group comprising an order or timing of first command signals and second commands signals to minimize deviation from the desired mixture in the flow of mixture-packets forming the desired mixture of two or more fluids in a conduit during the error event.

Embodiments of the invention provide apparatuses and methods for atomic layer deposition (ALD), such as plasma-enhanced ALD (PE-ALD). In some embodiments, a PE-ALD chamber is provided which includes a chamber lid assembly coupled with a chamber body having a substrate support therein. In one embodiment, the chamber lid assembly has an inlet manifold assembly containing an annular channel encompassing a centralized channel, wherein the centralized channel extends through the inlet manifold assembly, and the inlet manifold assembly further contains injection holes extending from the annular channel, through a sidewall of the centralized channel, and to the centralized channel. The chamber lid assembly further contains a showerhead assembly disposed below the inlet manifold assembly, a water box disposed between the inlet manifold assembly and the showerhead assembly, and a remote plasma system (RPS) disposed above and coupled with the inlet manifold assembly, and in fluid communication with the centralized channel.

An exercise device comprises a base having a generally planar top. The base is supported at a first height above a support surface by downwardly extending supports, or may be raised to a second height by one or more extendable feet. The exercise device may include an exercise tower rotatably mounted to the base and movable between a stored position under the base and a raised position in which it extends above the base. The base and tower may define one more exercise accessory attachment points or mounts and such accessories may be stored in a storage area associated with the tower.

Provided herein is relatively thick ionomeric sheeting that can be taken up into a roll and supplied in continuous form. Also provided herein are methods of manufacturing rolls of relatively thick, continuous ionomeric sheeting. Further provided herein are methods of producing glass laminates, wherein the relatively thick ionomeric sheeting is not conditioned to reduce curvature prior to stacking the pre-press assembly. These continuous rolls eliminate costly cutting and stacking steps in ionomeric sheeting that is intended for use as interlayers in laminated structures, for example safety glass and photovoltaic cells.
