摘要： A system and method for providing an improved micro-electro-mechanical (MEMS) electrothermal actuator is disclosed. In prior art electrothermal actuators an electric current passes through a narrow arm and returns through a wide arm. The larger current density in the narrow arm heats the narrow arm so that it expands more than the wide arm. The differential expansion of the hot narrow arm and the cold wide arm deflects the end of the cold wide arm. The present invention provides an additional hot arm to provide a return path for the electric current so that the cold arm does not conduct electric current. The present invention optimizes power consumption, tip deflection and generated force. A bidirectional thermal beam actuator is also disclosed.

摘要： An in-plane thermal buckle-beam microelectrical mechanical actuator is formed on a planar substrate of semiconductor material, for example. The actuator includes first and second anchors secured to the substrate and a floating center beam positioned between the first and second anchors and movable relative to the substrate. Symmetric first and second sets of elongated thermal half-beams are secured between opposite sides of the floating center beam and the respective first and second anchors. The half-beams are formed of semiconductor material, such as polysilicon. A current source directs electrical current through the thermal half beams via the anchors to impart thermal expansion of the thermal half-beams and hence linear motion of the floating center beam generally parallel to the substrate. In one implementation, the half-beams are configured at a bias angle to give the floating beam an affinity for in-plane motion. An actuator of the present invention with such bias angles can give the actuator an overall chevron configuration.

摘要： The present invention provides heat exchanging elements for use in Stirling engines. According to the present invention, the heat exchanging elements are made from muliple platelets that are stacked and joined together. The use of platelets to make heat exchanging elements permits Stirling engines to run more effiecient because the heat transfer and combustion processes are improved. In one embodiment, multi-stage combustion can be introduced with platlets, along with the flexibility to use different types of fuels. In another embodiment, a single component constructed from platelets can provide the heat transfer requirements between the combustion gas/working gas, working gas in the regenerator and the working gas/coolant fluid of a Stirling engine. In another embodiment, the platelet heat exchanging element can recieve solar energy to heat the Stirling engine's working gas. Also, this invention provides a heat exchanging method that allows for multiple fluids to flow in opposing or same direction.

摘要： An actuator for a device such as a tappet of a valve. The actuator having a thermostatic operating element electrically heated by an electrical heating element, and including an operating piston. A proportional piston stroke regulator detects and controls the position of the operating piston. The proportional piston stroke regulator includes a piston travel detection device, that detects the actual position of the operating piston, connected to a conventional closed-loop controller which compares the measured piston position to a predetermined piston control position entered into the closed-loop controller. Based on the comparison, the closed-loop controller regulates the electrical supply to the electrical heating element.

摘要： A micrometer sized multi-directional thermal actuator capable of repeatable and rapid displacement in a substantially horizontal direction, a substantially vertical direction, and/or a combination thereof. The multi-directional thermal actuator constructed on a surface of a substrate includes three or more beams each cantilevered from one or more anchors at a first end to extend generally parallel to the surface of the substrate. A member mechanically and electrically couples the distal ends of the beams. Application of current to a circuit comprising combinations of any two or more of the beams displaces the member in one of three or more non-parallel radial directions, respectively.

摘要： The invention includes processes and products made by the processes. The processes include making forms and parts by friable mold casting or die casting using molten Nitinol poured or injected into the mold or die. After the Nitinol has cooled to a solid state, it is removed from the mold by disintegrating the friable material of the mold and is heated to an elevated temperature under high pressure to consolidate the Nitinol and remove any internal voids. The parts and forms are then heat treated to reduce brittleness and improve toughness and impact strength. The part may be hot machined to reduce it to near net size, and may be ground to reduce the part to the exact specified part size. For example, cylindrical parts can be centerless ground; balls can be ground in a conventional ball grinder; flat stock can be surface ground. For parts requiring a smooth surface finish, polishing or lapping provides the specified surface finish on the part, down to 0.5 microinch RMS or finer. The part may be heat treated to obtain the desired hardness, from RC40 to RC65. An integral surface oxide of any of several colors can be formed on the surface of the part. The oxide surface may itself be polished to an even finer surface finish. Shape memory effect may be obtained in Type 60 Nitinol parts and forms that have been hot-worked by heat treating to about 675° C.-700° C. and oven cooling slowly over 8-10 hours to ambient temperature.
摘要翻译：本发明包括由该方法制备的方法和产品。这些方法包括通过使用熔融的镍钛诺（Eloy）浇注或注入模具或模具中的脆性模铸或压铸来制造形式和零件。在镍钛诺已经冷却到固态之后，通过将模具的易碎材料分解，将其从模具中除去，并在高压下加热至高温以固化镍钛诺并除去任何内部空隙。然后对这些部件和形式进行热处理以降低脆性并提高韧性和冲击强度。该部件可以被热加工以将其减小到接近净尺寸，并且可以被研磨以将部件减小到确切的指定部件尺寸。例如，圆柱形部件可以是无心磨削的; 球可以在传统的球磨机中研磨; 平面库存可以是地面。对于需要光滑表面光洁度的部件，抛光或研磨可在部件上提供指定的表面光洁度，低至0.5微英寸RMS或更细。该部件可以被热处理以获得期望的硬度，从RC40到RC65。可以在部件的表面上形成多种颜色中的任何一种的整体表面氧化物。氧化物表面本身可以被抛光到更细的表面光洁度。形状记忆效应可以通过热处理至约675℃-700℃和烘箱在8-10小时内缓慢冷却至环境温度的60型镍钛诺部件和形式中获得。

摘要： A stirling cycle engine whose cylinder, including a mount, can be easily fabricated and securely attached. The stirling cycle engine of the invention comprises a casing having a cylindrical portion 2; a metallic cylinder 7 coaxially inserted into the cylindrical portion 2 of the casing 1; a piston 15 inserted into the cylinder 7; a drive mechanism 16 for reciprocally driving the piston 15; and a mount 28 which is attached to an outer periphery of the cylinder 7 for fixing the cylinder 7 to the casing 1 and retaining the drive mechanism 16. The mount 28 is made of a material of low heat conductance, constructed separately from the cylinder 7. The mount 28 is attached to the outer periphery of the cylinder 7. Thus, the easier working thereof is resulted, so that the working time is shortened, to thereby improve productivity, and reduce working costs. Further, The heat from the drive mechanism 16 is less likely to transfer to the cylinder 7 via the mount 28.

摘要： A heat engine is constructed from sheet metal and the like. The heat engine has an outer container and inner container which contains a displacer and a power piston. A plurality of positioning members are provided to dimensionally stabilize the inner and outer containers. By providing positioning members that extend between the inner and the outer containers, a sandwiched construction is obtained which allows the inner and outer containers to reinforce each other thus permitting the use of thin walled containers and improving the thermal efficiency of the heat engine and decreasing the weight of the heat engine.

摘要： To control a relative rotation between two elements (10, 12), such as flaps of a deployable mechanical structure, on a space vehicle, a torsion bar (16) is used made of a bistable shape memory alloy, heated over its whole length by heaters stuck on the bar and retained by hooping rings. A stop (22) restricts pivoting to the pre-set pivoting angle to be controlled. Excess pivoting of the torsion bar (16) is applied to a mechanical fuse (18), interposed between the bar and one (12) of the elements.
