Patent EP-0130739-A2 (EP)
Inventor: URDEA MICKEY S
IPC: B01J19/00
Filed: 1984-06-20
Abstract: A reactor system and method for synthesizing or degrading polynucleotides and other linear polymers includes a tubular reactor (12) connected to a reagent manifold (14). The polynucleotide is immobilized on a loosely packed solid-phase support material in the tubular reactor (12), and reagents are sequentially introduced into the tubular reactor. After each reagent is introduced, the tubular reactor is isolated from the reagent manifold (14) and the reagent agitated by alternatively pressurizing the opposite ends of the tubular reactor. The method provides rapid and efficient synthesis of polynucleotides. By connecting two or more tubular reactors (12) to the reagent manifold (14), a plurality of polynucleotides having different sequences may be synthesized simultaneously.

Abstract: @ A recording and readout information system having atomic scale densities comprises a recording medium having a carrier (16) and means (20, 30) to form a pattern of atomic paticles (18A) on the surface of the carrier. The atomic particles have an affinity for the carrier and can adhere to the surface to form a relatively adhesive and stable bond. The pattern of atomic particles produced on the carrier are representative of recorded information, e.g. binary represented information, of ultra high density based upon the size and spacing of such particles, which is in the range, for example, of 5A (.5 nm) to 10A (1 nm). A preferred embodiment of the invention comprises a recording medium with an adsorbent carrier, and means to form a pattern of adsorbate atomic particles on the surface of the adsorbent carrier, the adsorbate atomic particles having an adsorptive affinity for the adsorbent carrier due - at least in part - to electrical attraction characteristics between the adsorbate atomic partiles and the adsorbent carrier. Readout means (30), utilizing the tunnel current effect, is employed to determine the presence or absence of the atomic particles on the surface of the carrier and produce an electrical signal representative of the pattern of recorded information on the recording medium.

Abstract: An oxygen-impervious pad structure (100) which reduces the bird's beak profiles in semi-recessed oxide isolation regions. The sidewalls of a conventional silicon oxide (12) - silicon nitride (14) pad are coated with a thick layer (20) of oxynitride. A thin layer (18) of oxynitride is grown on the substrate surface prior to deposition of the thick oxynitride layer. The thick oxynitride layer prevents lateral oxidizing specie diffusion through the oxide layer of the conventional pad, and the thin oxynitride layer prevents oxidizing specie diffusion through the pad-substrate interface into the substrate region beneath the pad.

Abstract: @ An evoked potential autorefractometry system includes a computer driving an alternating checkerboard mirror stimulus to project a stimulus pattern directly to a patient through a continuously variable focus lens controlled by the computer and maintaining a constant image size on the patient's retina. The evoked potentials produced by the patient are amplified and asynchronously filtered both in an analog and digital fashion to allow peak to peak detection of the evoked potentials to determine amplitude. The digital filter includes a 255 point running sum. The peak to peak amplitudes are asynchronously digitally filtered using a 16 point running sum to produce an amplitude measure of the evoked potentials. The lens is swept rapidly from one extreme of focus to the other extreme in relatively large steps to determine the area in which the peak amplitude occurs. The lens is then swept in smaller and smaller range sweeps using smaller and smaller steps around the peak amplitude until the peak in the amplitude is pinpointed within a desired diopter at which point the lens position is printed out on the printer as the patient's prescription.
