Abstract: A method for coating free-standing micromechanical devices using spin-coating. A solution with high solids loading but low viscosity can penetrate the free areas of a micromachined structure. Spinning this solution off the wafer or die results in film formation over the devices without the expected damage from capillary action. If an organic polymer is used as the solid component, the structures may be re-released by a traditional ash process. This method may be used as a process in the manufacture of micromechanical devices to protect released and tested structures, and to overcome stiction-related deformation of micromechanical devices associated with wet release processes.

Abstract: A nonstaining ink (or inkless) fingerprint composition and applicator comprises two nonpermeable foil strips, made of Mylar, for example, having the same width with one strip being slightly longer than the other. A thin layer or coating of an inkless (or nonstaining) fingerprint composition is sandwiched between the superimposed foil strips leaving a small border including a small area at the end of the strips free of the composition. The inkless composition which includes a color former and may or may not include a developer is in a semisolid state and room temperature and in a liquid state at about 110° F. and above.

Abstract: A manufacture method for forming a disposable plate electrode with biological active film is used to cooperate with a biological sensor for analyzing composition and measuring concentration of a test sample according to electric effect resulted from a biochemical reaction. The plate electrode comprises at least an electrode portion for transmission of the electric effect as well as a biological active film that reacts with the test sample chemically or biochemically. The biological active film contains a carrier layer (cellulose, for example) for adsorbing and keeping the biological active substance (enzyme, for example), which, the carrier layer, can change the electrode portion from hydrophobic into hydrophilic and protect the biological active substance against impairment during relatively higher temperature drying process.

Abstract: A high quality ink jet recording medium is formed of a dimensionally stable absorbent paper base sheet and a coating that is primarily a reaction product of polyvinyl alcohol and boric acid. The reaction product has molecule bonds that are principally polyvinyl alcohol-boric acid-polyvinyl alcohol bonds which, when applied to the substrate, form a three-dimensional sieve or screen-like coating facilitating penetration to the absorbent base-sheet of ink carrier vehicle and holding out on the sieve or screen the ink pigments and colorants. The coating facilitates manufacture of a high quality recording medium of exceptionally low cost, ideally suited for high-speed multicolor ink jet printing in continuous web form. Methods of making the coating and the medium are disclosed.

Abstract: A method for creating a multiwalled container capable of safely holding a desired liquid. The container may be formed using a mold or form or may be formed on the inside of an existing shell or structure, thereby incorporating the shell or structure as part of the container. The mold or shell is prepared and coated with a first, impermeable polymer layer. An interstitial material is then applied to the first polymer layer and a second impermeable polymer layer is then applied to the permeable, interstitial material. This creates an interstitial space between the two impermeable polymer layers. The process of applying interstitial material and additional polymer layers may be repeated as many times as necessary to achieve the desired number of impermeable walls within the container.

Abstract: A method of making an electret includes condensing vapor from the atmosphere of a controlled environment onto a dielectric article and then drying the article to remove the condensate. The dielectric article may be a nonconductive polymeric material, and the condensate may include a polar liquid. The method is particularly useful for forming an electret from a porous material such as a nonwoven fibrous web. The method can enable individual fibers in the web to exhibit at least quasi-permanent electrical charge.

Abstract: A method for electrostatic spray-coating a medical device having a tubular wall, such as a stent, having an inner surface, an outer surface and openings therein. The tubular wall is grounded or electrically charged, and an electrically charged conductive core wire is located axially through the center of the stent. An electrical potential is applied to the conductive core wire to impart an electrical charge to the conductive core wire. The tubular wall is exposed to an electrically charged coating formulation, and the electrically charged coating formulation is deposited onto a portion of the tubular wall to form a coating. The electrical potentials of the conductive core wire and tubular wall can be repeatedly alternated.

Abstract: The uniformity of a wet coating on a substrate is improved by contacting the coating at a first position with the wetted surfaces of periodic pick-and-place devices, and re-contacting the coating with such wetted surfaces at positions on the substrate that are different from the first position and not periodically related to one another with respect to their distance from the first position. A coating is applied to a substrate by applying an uneven wet coating, contacting the coating at a first position with the wetted surfaces of periodic pick-and-place devices, and re-contacting the coating with such wetted surfaces at positions on the substrate that are different from the first position and not periodically related to one another with respect to their distance from the first position. These methods can provide extremely uniform coatings and extremely thin coatings, at very high rates of speed. The coatings can be applied in lanes with sharply defined edges and independently adjustable coating calipers.

Abstract: A portable, self-contained, electronic radioscopic imaging system uses a pulsed X-ray source, a remote X-ray sensor, and a self-contained, display and controller unit to produce, store, and/or display digital radioscopic images of an object under investigation in low voltage imaging environments such as medical applications including mammography and tissue imaging, and industrial radiography of low-density structures, or the like. The radiographic system uses an X-ray converter screen for converting impinging X-ray radiation to visible light, and thus each point impinged on the screen by X-ray radiation scintillates visible light emissions diverging from the screen. An image sensor, i.e., a CCD camera, is configured to sense the visible light from the screen. An aspheric objective lens operable with the CCD camera spatially senses visible light within a collection cone directed outwardly from the image sensor. An emission modification lens layer, e.g.

The thickness of the polyethylene slip coating applied to most commercial glass bottles is in the range 75-100 &mgr;m. The coating is removed by the process outlined above sufficiently to allow the application of an adherent decorative coating to the surface.

Abstract: A method of manufacturing a silica-containing article used in the manufacture of an optical fiber includes the steps of applying to the silica-containing article a protective layer, and then transporting the coated article to a second factory for further processing. The layer facilitates ease of removal of particulates that deposit on the protective layer. The layer preferably ablates during, or can be readily removed subsequent to, further processing of the silica-containing article. Any intermediate product used in the manufacture of an optical fiber, for example, a core blank, core cane segment, consolidated preform, etc. may be readily shipped between various factories because the articles are protected against break-inducing particulates by the protective layer.
