A method for sealing through-holes in a material via material diffusion, without the deposition of a sealant material, is disclosed. The method is well suited to the fabrication and packaging of microsystems technology-based devices and systems. In some embodiments, the method comprises forming sacrificial material release through-holes through a structural layer, removing the sacrificial material via an etch that etches the sacrificial material through the release through-holes, and sealing of the release through-holes via material diffusion.

A suspension for an air-bearing slider 32 in a data recording disk file is an envelope 30 which expands when pressurized air enters the envelope interior. The envelope 30 includes a pair of flat flexible sheets 50, 52, preferably of polyimide, which are secured at their perimeters 54, and stiffeners 40, 42, 56 bonded to the sheets 50, 52 to provide stiffness between the slider 32 and the arm attached to the disk file actuator. Four parallel strips 60, 62, 63, 64 on the polyimide sheets 50, 52 function as hinges so that the envelope expands in the manner of a four-bar linkage, thus moving the slider 32 toward the disk with the slider's air-bearing surface maintained generally parallel to the data surface of the disk. Electrical conductors 80 for connecting the read/write transducer 33 supported on the slider 32 to the read/write circuitry of the disk file are formed on one of the polyimide sheets 50.

A toroidal lens has a first surface comprised of a convex curve rotated about a central axis and a second surface comprised of a concave curve rotated about the central axis. The toroidal lens receives a radiation beam and produces an annular or halo shaped radiation beam. This resulting annular beam is focussed by a focussing lens to a reduced focus spot size without sacrificing depth of focus.

(57) Abstract: Bioartificial ultrafiltration devices comprising a scaffold comprising a population of cells enclosed in a matrix and disposed adjacent a plurality of channels are provided. The population of cells provides molecules such as therapeutic molecules to a subject in need thereof and is supported by the nutrients filtered in an ultrafiltrate from the blood of the subject. The plurality of channels in the scaffold facilitate the transportation of the ultrafiltrate and exchange of molecules between the ultrafiltrate and the population of cells.
