摘要： An outlet airflow direction control unit mainly includes a frame and a fan mounted in the frame. The frame has an inlet and an outlet via which an amount of fluid flows into and out of the frame, and is internally provided at predetermined positions with a plurality of radially projected fluid control elements. When the fan is rotated to cause an amount of fluid to flow through the outlet of the frame, the fluid control elements provided in the frame are adapted to control a flow direction of the fluid flown out of the outlet.

摘要： A housing part, which can be firmly joined to another housing part for the formation of a housing of a radial flow compressor, in particular a turbocharger. At least one open or closed channel portion is provided in each housing part so that when the housing parts are joined a channel system is formed which runs between the two housing parts. A free-flowing and hardening compaction material, such as an adhesive or a thermoplastic polymer, is inserted into the channel system for the formation of a firm bond between the two housing parts.

摘要： A steam turbine 1 constructed in accordance with the present invention comprises a high-pressure module 2 and a low-pressure module 3, a speed-reducing gearbox 4, and an alternator, and wherein the high-pressure module 2 has a single stage of blades 20. This single stage of blades 20 performs the same function as a multi-stage high-pressure module, but with a blade design that is different from the blade design of multi-stage steam turbines. For example, the pressure ratio between the inlet and the outlet of the high-pressure module 2 may be in the range 3 to 20.

摘要： The rotor is positioned above a work-piece and has a number of curved downwardly extending blades. A nozzle directs cooling liquid onto the leading surface of successive blades as the rotor rotates The blades re-direct the cooling liquid against a bit or drill used to cut the work-piece. The blades also direct the liquid into the pocket cut by the bit or drill in the work-piece in order to drive out any debris which collects in the pocket.

摘要： A direct drive, high velocity, high power centrifugal air blower. The blower employs a high-speed electric motor (>15,000 rpm) having an output drive shaft that is directly coupled to an impeller rotatably housed within a volute. The assembly enables the impeller to rotate at speeds up to 100,000 rpm without the need for either step-up gears or belts and pulleys interposed between the motor output drive shaft and the impeller. The elimination of an indirect coupling assembly between the motor ouput shaft and the impeller provides a high power, high velocity blower/vacuum with greater reliability than indirectly coupled assemblies.
摘要翻译：直接驱动，高速，高功率离心风机。鼓风机采用具有直接联接到可旋转地容纳在蜗壳内的叶轮的输出驱动轴的高速电动机（> 15,000rpm）。该组件使得叶轮可以以高达100,000rpm的转速旋转，而不需要将升降齿轮或皮带和滑轮置于电动机输出驱动轴和叶轮之间。在电机输出轴和叶轮之间消除间接耦合组件可提供比间接耦合组件更高可靠性的高功率，高速风机/真空。

摘要： A centrifugal air blower unit includes a centrifugal multi-blade fan, a scroll casing, and an introduction duct. The fan has a rotation axis and a plurality of blades. The scroll casing provides a first air passage. The introduction duct provides a second air passage. The fan sucks the air from the rotation axis and blows the air toward the outer circumference of the fan. The first and second air passages flow the air blown from the fan. The inner wall of the introduction duct includes a movable portion. The inner wall of the introduction duct is smoothly jointed between the first and second air passages even when the movable portion is displaced in accordance with the airflow amount of the air blown from the scroll casing.

摘要： According to the invention, the stator is made by radially assembling together at least two stator sectors (21, 22) about a rotor (18). Each stator sector (21, 22) comprises a peripheral shell sector (24, 25) provided with internal annular grooves (24a-24j) in which stator vane sectors (26a-26j) are engaged individually. This facilitates assembly and provision of subassemblies constituting the turbomolecular pump.
