摘要： The disc drive housing encloses a spindle motor carrying a disc having a data surface. An actuator assembly includes an actuator arm carrying a head. The housing includes a first surface portion adjacent to the data surface of the disc. The housing also includes a plurality of surface portions that define a recess, which allows the actuator arm to move over the data surface of the disc. The plurality of surface portions include a sloped surface portion sloping away from the data surface and preventing wind generated by the disc rotating about an axis from separating from the sloped surface portion. Alternatively, a disc drive includes a housing that defines a recess. The housing encloses a disc mounted on a spindle motor that rotates the disc about an axis and thereby generates wind within the housing. An upstream surface portion and a downstream surface portion of the housing both face toward a data surface of the disc. A discontinuity, such as a step, between the upstream surface portion and the downstream surface portion causes a wind recirculation region within the recess. The disc drive also includes an actuator arm that carries a head, which the recess allows to move over the data surface of the disc. An actuator limiting device prevents the actuator arm from entering the wind recirculation region.

摘要： Microfluidic devices are disclosed which can be manufactured using surface-micromachining. These devices utilize an electroosmotic force or an electromagnetic field to generate a flow of a fluid in a microchannel that is lined, at least in part, with silicon nitride. Additional electrodes can be provided within or about the microchannel for separating particular constituents in the fluid during the flow based on charge state or magnetic moment. The fluid can also be pressurized in the channel. The present invention has many different applications including electrokinetic pumping, chemical and biochemical analysis (e.g. based on electrophoresis or chromatography), conducting chemical reactions on a microscopic scale, and forming hydraulic actuators.

摘要： A combustible gas sensor that uses a resistively heated, noble metal-coated, micromachined polycrystalline Si filament to calorimetrically detect the presence and concentration of combustible gases. The filaments tested to date are 2 .mu.m thick.times.10 .mu.m wide.times.100, 250, 500, or 1000 .mu.m-long polycrystalline Si; some are overcoated with a 0.25 .mu.m-thick protective CVD Si.sub.3 N.sub.4 layer. A thin catalytic Pt film was deposited by CVD from the precursor Pt(acac).sub.2 onto microfilaments resistively heated to approximately 500.degree. C.; Pt deposits only on the hot filament. Using a constant-resistance-mode feedback circuit, Pt-coated filaments operating at ca. 300.degree. C. (35 mW input power) respond linearly, in terms of the change in supply current required to maintain constant resistance (temperature), to H.sub.2 concentrations between 100 ppm and 1% in an 80/20 N.sub.2 /O.sub.2 mixture. Other catalytic materials can also be used.

摘要： The present invention is directed towards apparatuses for rotating a gimbaled platform with rotatable actuators. Gimbal springs comprised of component springs with compliant axes that intersect at a nonzero angle are coupled to the gimbaled platform. Preferably, the compliant axes of the component springs are oriented at an approximately 45 degree angle relative to the actuator rotation axes. Wraparound lever arms coupling the rotatable actuators with the gimbal springs serve to increase the leverage ratio, thereby permitting greater platform rotation for a given actuator rotation.

摘要： A tool for holding nuts or bolts while being moved to a desired position opposite a complementary bolt or nut includes a shaft made of steel spring wire having a handle at one end, the wire terminating at the other end in a loop having a diameter slightly smaller that the diameter of a nut or bolt to be held by the loop, the loop being shaped so that, when a nut or bolt is fitted into the loop, the loop will grip the nut or bolt with sufficient force to hold it as it is brought into a desired position. The diameter of the wire is less than 0.070 inches, and preferably 0.063 or 0.060 inches, so that the shaft will have sufficient flexibility to enable the tool to fit into curved as well as linear spaces, while still holding a nut or bolt securely. The end of the loop terminates in a hook or U-shape, permitting the tool to easily be formed on a kick press without the need for special tooling and greatly simplifying manufacture of the tool. Finally, the handle of the tool is formed with a central passage into which the end of the shaft is fitted and secured by an easily removable fastening element such as an Allen screw so that other similar tools may share the same handle to form a modular tool system.
