Micromachined spinneret

Okandan, Murat; Galambos, Paul

Title: Micromachined spinneret

Abstract

A micromachined spinneret is disclosed which has one or more orifices through which a fiber-forming material can be extruded to form a fiber. Each orifice is surrounded by a concentric annular orifice which allows the fiber to be temporarily or permanently coated with a co-extrudable material. The micromachined spinneret can be formed by a combination of surface and bulk micromachining.

Physics-based signal processing algorithms for micromachined cantilever arrays

Patent Candy, James V; Clague, David S; Lee, Christopher L; ...

A method of using physics-based signal processing algorithms for micromachined cantilever arrays. The methods utilize deflection of a micromachined cantilever that represents the chemical, biological, or physical element being detected. One embodiment of the method comprises the steps of modeling the deflection of the micromachined cantilever producing a deflection model, sensing the deflection of the micromachined cantilever and producing a signal representing the deflection, and comparing the signal representing the deflection with the deflection model.

Reversible micromachining locator

Patent Salzer, Leander J [Los Almos, NM]; Foreman, Larry R [late of Los Alamos, NM]

A locator with a part support is used to hold a part onto the kinematic mount of a tooling machine so that the part can be held in or replaced in exactly the same position relative to the cutting tool for machining different surfaces of the part or for performing different machining operations on the same or different surfaces of the part. The locator has disposed therein a plurality of steel balls placed at equidistant positions around the planar surface of the locator and the kinematic mount has a plurality of magnets which alternate with grooves which accommodate the portionsmore » « less

Micromachine friction test apparatus

Patent deBoer, Maarten P [Albuquerque, NM]; Redmond, James M [Albuquerque, NM]; Michalske, Terry A [Cedar Crest, NM]

A microelectromechanical (MEM) friction test apparatus is disclosed for determining static or dynamic friction in MEM devices. The friction test apparatus, formed by surface micromachining, is based on a friction pad supported at one end of a cantilevered beam, with the friction pad overlying a contact pad formed on the substrate. A first electrostatic actuator can be used to bring a lower surface of the friction pad into contact with an upper surface of the contact pad with a controlled and adjustable force of contact. A second electrostatic actuator can then be used to bend the cantilevered beam, thereby shorteningmore » « less

Micromachined cutting blade formed from {211}-oriented silicon

Patent Fleming, James G [Albuquerque, NM]; Fleming, legal representative, Carol (Burbank, CA); Sniegowski, Jeffry J [Tijeras, NM]; ...

A cutting blade is disclosed fabricated of micromachined silicon. The cutting blade utilizes a monocrystalline silicon substrate having a {211} crystalline orientation to form one or more cutting edges that are defined by the intersection of {211} crystalline planes of silicon with {111} crystalline planes of silicon. This results in a cutting blade which has a shallow cutting-edge angle .theta. of 19.5.degree.. The micromachined cutting blade can be formed using an anisotropic wet etching process which substantially terminates etching upon reaching the {111} crystalline planes of silicon. This allows multiple blades to be batch fabricated on a common substrate andmore » « less
