摘要： A peristaltic piezoelectrically actuated fluid pump including two or more pairs of piezoelectric deformable members that are self-actuated, a flexible hose member, a pump chamber, inlet and outlet ports for communicating the pump chamber with the exterior of the flexible hose member, valves for opening and closing the ports, and a power supply is provided. The diaphragm members may include a prestressed piezoelectric element which is durable, inexpensive and lightweight as compared with diaphragm members of prior diaphragm pumps of comparable discharge capacity, and is actuated via electrical signals from an outside power source. Each pair of piezoelectric diaphragm members is actuated out of phase with the other(s) so as to allow fluid to be pumped through the flexible hose member peristaltically.

摘要： A method for manufacturing pre-stressed piezoelectric actuators using a pre-curved piece of ceramic is provided. An adhesive, preferably a polyimide, is disposed between a metal pre-stress metal layer and a pre-curved PZT ceramic. The entire composite structure is heated to a temperature above the melting point of the adhesive material and then subsequently cooled to allow the adhesive layer to set. As a result of the difference in thermal contraction rates of the materials, the pre-curved PZT ceramic is compressively stressed. This pre-stressing provides a piezoelectric actuator which is durable, and produces a higher displacement than a conventional piezoelectric actuator.

摘要： An automatically resetting mechanical valve used to control unwanted discharge of liquids less dense than water, principally oil, which may be present in waste water flows. The valve is closed by sinking both a primary float and a secondary float, each less dense than water but more dense than the liquid whose discharge is to be stopped. The sinking primary float effectively closes an orifice in an outlet conduit upon the sinking primary float's becoming sufficiently immersed in the less dense liquid. Upon the reintroduction of water, the secondary float acts upon a lever of high mechanical advantage, which pries the primary float upward, which, in turn, allows hydraulic pressure inside and outside the conduit to equalize, thereby allowing the primary float to unseat and the valve to automatically re-open.

摘要： Automatically resetting mechanical valve is used to control unwanted discharge of liquids less dense than water, principally oil, which may be present in waste water flows. The valve is closed by the sinking of a primary flow which closes a primary orifice, and the floating of a secondary float which closes a smaller secondary orifice. The primary float is less dense than water but more dense than oil. The secondary float is less dense than both oil and water. When the primary float becomes sufficiently immersed in oil, the primary float sinks and effectively closes the primary orifice in an outlet conduit. In the event of evaporation or removal of liquid from the valve, the (smaller) secondary orifice automatically opens, thereby allowing hydrostatic pressure inside and outside of the outlet conduit to equalize. Upon reintroduction of water to the device, the primary float unseats and the valve automatically re-opens. Additionally ingress of liquid causes the secondary float to float, thus closing the secondary orifice.
摘要翻译：自动复位机械阀门用于控制不同于水的液体不必要的排放，主要是可能存在于废水流中的油。阀被封闭初级孔的初级流的下沉以及关闭较小次级孔的次级浮子浮起而封闭。主要浮游物比水密度低，但比油更致密。二次浮子比油和水都不那么密集。当主浮子充分浸入油中时，主浮子沉入并有效地封闭出口导管中的主孔。在从阀门蒸发或去除液体的情况下，（较小的）次级孔口自动打开，从而允许出口导管内部和外部的流体静压力均衡。一旦将水重新引入设备，主浮球就会自动重新打开。另外进入液体会使二次浮子浮起，从而关闭二次孔。

摘要： An elastomeric sealing device to prevent ingress of surface fluids into holes, principally drains which are characterized by non-watertight covers or grilles with either regular or irregular topographic boundaries. The device comprises a three-part construction, including a top film, a core elastomer having minimal shear strength, and a bottom film. When in use, the device conforms to contour of adjacent hole covering device and fills existing crevices and voids, thereby providing an efficient seal. When removed from hole, device recovers neutral shape thereby being suitable for re-use on same or different hole.

摘要： Protection of the thin gate oxide of MOS field effect transistors from irreversible puncture due to undesired high voltages and currents generated by electrostatic discharge through handling or otherwise, is provided by a circuit structure at each input pad of an integrated circuit chip. One such feature includes the use of a barrier layer of polysilicon material to make an electrical contact between source and drain diffusions of a protective transistor and their respective aluminum conductors, in order to increase the amount of current that can be handled at such contacts without the aluminum conductor fusing though a diffusion into the substrate. Another such feature is to provide an initial, and perhaps only, protective transistor that has a very narrow channel between source and drain diffusions to allow a reversible breakdown to reduce the voltage across it to within, or nearly within, the maximum voltage that the protected thin gate oxide transistor can handle without being damaged. Further, current concentrations in the protective transistor are minimized by the use of elongated diffusions and associated solid elongated conductors having rounded corners.

摘要： A small, lightweight, efficient, quiet electric shaver is provided in which one or more piezoelectric drivers are mechanically coupled to a cutting blade. The cutting action of the blade is generated by the piezoelectric drivers which, when electrically energized, oscillate at a predetermined frequency. The piezoelectric driver is electrically energized by a regenerative drive circuit. Hair shafts, which protrude from the surface to be shaved through a perforated foil member, are sheared at their base by the oscillating action of the blade.

摘要： A method and apparatus for manufacturing prestressed piezoelectric actuators which maximizes output, and increases the precision and efficiency with which the multi-layer actuators are made. Individual layers of the piezoelectric actuators are automatically stacked and registered with respect to each other within press members prior to bonding the layers to each other with a thermoplastic adhesive. Compressive force is applied while heat is conductively transferred from a heating element to the actuator in order to raise the temperature of each of the layers above the melting point of the thermoplastic. The temperature of the heating element is then decreased until the temperature of the actuator layers drops to below the melting point of the thermoplastic adhesive, thereby bonding the layers. Compressive force is then released, and the actuators are removed, further cooled and polarized. The temperature of the actuator may be sensed, and the pressure and the heat applied to the actuator varied in accordance with the sensed temperature.
