A compliant wheel includes a compliant band and a plurality of web spokes extending transversely across and inward from the reinforced compliant band for attachment to a hub. The compliant band bends to comply with a contact surface and to envelope obstacles. The web spokes transmit load forces between the compliant band and the hub through tension in the web spokes not connected to the ground contacting portion of the wheel. The outer surface of the compliant band may be formed to include a tread, or a separate tread band may be attached.

An immersion processing system is provided for cleaning wafers with an increased efficiency of chemical use. Such a system advantageously uses less cleaning enhancement substance that may be provided as gas, vapor or liquid directly to a meniscus or wafer/liquid/gas bath interface so as to effectively modify surface tensions at the meniscus with minimized chemical usage. Such a delivery system design may be applied for single wafer processing or for processing multiple wafers together within a single liquid bath vessel. For single wafer processing, in particular, cleaning enhancement substance can be delivered along one or both major sides of the wafer, preferably at the meniscus that is formed as the wafer and liquid are relatively moved, while a processing vessel usable for such single wafer processing may itself be designed with a minimized size to accommodate a single wafer. By reducing the vessel volume, chemical usage for any processing chemicals that are to be provided within a liquid bath may also be advantageously reduced.

The invention relates to a two-degree freedom rope traction and parallel-connection mechanism which comprises a rack and a dynamic platform. The mechanism is characterized by also comprising an intermediate branched chain and two groups of rope traction branched chains, the intermediate branched chain is formed by hinging two rotational joints which are vertical mutually and is installed at the center position between the rack and the dynamic platform; the two groups of rope traction branched chains have the same structures and are installed between the rack and the dynamic platform in a crossway by taking the intermediate branched chain as a center, and each group of rope traction branched chains is driven by a motor fixed on the rack, and the motor drives a rope to drive the dynamic platform through a tension mechanism and a pulley mechanism to rotate around the intermediate branched chain, thereby realizing that the dynamic platform can rotate in two mutually vertical directions. The invention is a non-redundant drive and has simple mechanism and can be controlled easily.

A method and instrument for tensioning a flexible tie used for fastening an implant on a bony element by forming a first loop around it. In some embodiments, the instrument comprises a shaft having a distal end configured for contact with a rod, a moving part slidably engaged with the shaft, a holder connected to the moving part and configured to hold an end of the flexible tie, and a tension control member comprising a trigger that pivots relative to the moving part. In some embodiments, the method comprises coupling the end of the flexible tie to the instrument and squeezing the trigger to shorten the first loop of the flexible tie around the bony element, causing the moving part and the holder holding the end of the flexible tie to move in translation away from the distal end of the shaft, thereby exerting tension on the flexible tie.

The invention discloses a high-strength strip steel straightening, flattening and straightening process. The high-strength strip steel straightening, flattening and straightening process is characterized in that a hot rolling high-strength steel plate or strip steel sequentially passes through an inlet straightening machine, a temper mill and an outlet straightening machine, and by means of the combined working procedures of straightening, flattening and straightening, the adjustment of the plate shape, the surface quality, the mechanical performance and the residual stress of the strip steelis completed; the inlet straightening machine is used for conducting rough straightening on the strip steel, on the one hand, the plate shape of the supplied material is improved, and on the other hand, the scale on the surface of the strip steel is reduced; the temper mill is used for conducting flattening on the strip steel, the plate shape of the strip steel is improved, the mechanical performance of the strip steel is adjusted, and the surface quality of the strip steel is improved; and the outlet straightening machine is used for conducting precise straightening on the strip steel, the unquenched plate shape problems and newly-generated plate shape problems in the flattening process are solved, and the unquenched residual stress and newly-generated residual stress in the flattening process are eliminated.

Provided herein is a lightweight stroller that can be transitioned between a closed position and an open position. The stroller includes a seating portion and at least one frame supporting the seating portion and transitionable from an open position to a closed position. The frame includes at least a front support rotatably connected to rear support. The stroller also includes a cinching strap connected between the front support and the rear support. The cinching strap is configured such that, as the frame transitions from the open position to the closed position, the cinching strap pulls the rear support toward the front support or the front support toward the front support. The cinching strap may at least partially maintain the front support and the rear support in the closed position. The cinching strap may include a flexible portion formed from a string, cable, polymer sheet, braided webbing, or any combination thereof.

Plural auxiliary devices such as a water pump and a generator coupled to a serpentine belt-drive system are driven by an internal combustion engine mounted on an automobile vehicle. The generator is divided into a first generator having a pulley in which a one-way clutch is installed and a second generator having a usual solid pulley. Fluctuations in the belt tension caused by changes in instantaneous rotational speed of the internal combustion engine are suppressed or reduced by the one-way clutch installed in the pulley of the first generator. An inertia torque of a rotor of the first generator may be made higher than that of the second generator because effects of the inertia torque on the belt tension fluctuations are alleviated by the one-way clutch.

The present invention pertains to a composite girder for bridge construction. More preferably, a girder is formed in a rectangular shape that is horizontally long and opened at the top portion thereof, wherein the girder is convexly curved in the center so as to be formed in the shape of an arch. The girder has a compression section, a web and a tension section, which are integrally composed together; and is filled with concrete inside the girder so as to increase the sectional strength of the girder. Therefore, it is possible to reinforce a support that receives a great shearing stress even without the use of any rebar. Simultaneously, a stopper is formed on the inside surface of the compression section to prevent the separation of the steel materials and the concrete. Therefore, compared with the existing girders, the composite girder of the present invention may be mounted over a noticeably long span. In addition, it is possible to reduce manufacturing costs by minimizing the use of expensive steel reinforcement materials, exhibiting sufficient strength characteristics in spite of a small dead load.
