Abstract: The present disclosure provides three-dimensional (3D) printing systems, apparatuses, software, and methods for the production of at least one requested 3D object. The 3D printer includes a material conveyance system, filtering system, and/or an unpacking station. The material conveyance system may transport pre-transformed material (e.g., powder) against gravity. The 3D printing described herein facilitated reducing interruptions of (e.g., providing non interrupted) (ii) material recycling, and/or (i) material dispensing through a component of the 3D printer such as a layer dispenser. The material conveyance system may operate above ambient pressure, e.g., while performing a suction operation. The present disclosure provides three-dimensional (3D) printing processes, apparatuses, software, and systems for controlling and/or treating gas and gas borne debris in an atmosphere of a 3D printer.

Abstract: An embedded or buried resistive structure may be formed by amorphizing a semiconductor material and subsequently re-crystallizing the same in a polycrystalline state, thereby providing a high degree of compatibility with conventional polycrystalline resistors, such as polysilicon resistors, while avoiding the deposition of a dedicated polycrystalline material. Hence, polycrystalline resistors may be advantageously combined with sophisticated transistor architectures based on non-silicon gate electrode materials, while also providing high performance of the resistors with respect to the parasitic capacitance.

Abstract: A cart is configured to handle replaceable plates used on the blade of a plow or grader. The cart includes a wheeled frame and a plate holder configured to support the plate lengthwise in a generally upright orientation. The plate holder is supported on the frame by a parallelogram linkage that permits adjustment of the plate holder, and thereby the plate carried by the holder, without varying the orientation of these components. An inventive plate installation method is also disclosed. The method involves placing at least one plate on the height-adjustable plate holder carried on the mobile frame. The attachment holes defined in the plate are then aligned with the attachment holes defined in the blade.

Abstract: One method of making a semiconductor device includes forming a gate electrode on a substrate and forming a spacer on a sidewall of the gate electrode. An active region is then formed in the substrate and adjacent to the spacer, but spaced apart from the gate electrode, using a first dopant material. A halo region is formed in the substrate under the spacer and adjacent to the active region using a second dopant material of a conductivity type different than the first dopant material. The halo region may be formed by implanting the second dopant region into the substrate at an angle substantially less than 90° relative to a surface of the substrate. A portion of the spacer is then removed and a lightly-doped region is formed in the substrate adjacent to the active region and the gate electrode and shallower than the halo region using a third dopant material of a same conductivity type as the first dopant material.

Abstract: One method of forming a semiconductor device includes forming a gate electrode on a substrate and then forming a spacer adjacent to a sidewall of the gate electrode. An active region is formed in the substrate adjacent to the spacer and spaced apart from the gate electrode using a first dopant material of a first conductivity type. A protecting layer is formed over the active region and adjacent to the spacer. At least a portion of the spacer is then removed to form an opening between the protecting layer and the gate electrode. In some instances, the spacer may be formed by independent deposition of two different materials (e.g., silicon nitride and silicon dioxide), one of which can be selectively removed with respect to the other. A lightly-doped region is formed in the substrate adjacent to the gate electrode using a second dopant material of the first conductivity type.

Abstract: A rotor for crop handling machines has a plurality of double-pivoted, radially-extending arms and structure on the segments of each arm to position the segments such that any radially inwardly directed impact force, such as from stones and other obstructions, causes immediate buckling of the arm about its pivot points instead of fracturing the segments or bending their mounting pins. In one embodiment, each arm is provided with a positive stop between the segments that holds them in a pre-buckled condition such that the tip of the outer segment, with respect to the direction of rotation of the rotor, trails the common plane containing the pivotal axes of the double-pivoted arm. In a second embodiment the individual segments are constructed such that their centers of gravity are laterally offset, with respect to one another, causing the desired trailing relationship of the tip of the outer segment.

Abstract: In the interval between successive press cycles, crop material is picked up from the field and loaded into the stack-forming body of the machine. However, upon initiation of a press cycle, crop material, which continues to be picked up as the machine is advanced, is diverted into an accumulating chamber and collected within the latter until termination of the press cycle. Thereupon, the accumulation is discharged for recycling through the pickup and loading mechanism to be delivered into the forming body along with previously uncycled material. Alternative embodiments involve discharging the accumulation onto the ground ahead of the loader for pickup by the latter a second time, and discharging the accumulation either directly into the front or rear of the loader at a point above the ground.
