  • Patent number: 6287889
    Abstract: An improved gas phase synthesized diamond, CBN, BCN, or CN thin film having a modified region in which strain, defects, color and the like are reduced and/or eliminated. The thin film can be formed on a substrate or be a free-standing thin film from which the substrate has been removed. The thin film can be stably and reproducibly modified to have an oriented polycrystal structure or a single crystal structure. The thin film is modified by being subjected to and heated by microwave irradiation in a controlled atmosphere. The thin film has a modified region in which a line width of the diamond spectrum evaluated by Raman spectroscopy of 0.1 microns or greater is substantially constant along a film thickness direction of the thin film, and the line width of the modified region is 85% or less of a maximum line width of the residual portion of the film thickness.

  • Patent number: 6284111
    Abstract: A sputtering target is provided which provides early stabilization of the film-deposition rate of the sputtering target from its initial stage of use. The sputtering target surface subjected to erosion is formed with a surface-deformed layer. The surface-deformed layer is reduced by precision machining and removed by etching. The extent of etching is controlled so that the surface roughness (Ra) is in a range between 0.1% and 10% of the mean crystal grain diameter of the material constituting the target. The surface roughness (Ra) is defined as the mean roughness on the center line of the surface.

  • Patent number: 6284013
    Abstract: There is provided a high-purity ruthenium sputtering target with a low impurity content, in particular producing extremely few particles, which is suitable for applications such as the formation of semiconductor thin films. The high-purity ruthenium sputtering target is manufactured by feeding crude ruthenium powder into a sodium hydroxide solution; blowing an ozone-containing gas while or after blowing chlorine gas into the solution to form ruthenium tetroxide; absorbing the ruthenium tetroxide in a hydrochloric acid solution or a mixed solution of hydrochloric acid and ammonium chloride, and evaporating the solution to dryness; sintering the resultant ruthenium salt in a hydrogen atmosphere to form high-purity ruthenium powder; and hot-pressing the ruthenium powder into a sputtering target.

  • Patent number: 6277024
    Abstract: An adjustable-pitch sectional roof ridge vent formed as a one-piece, plastic, injection-molded body having an elongate top wall and a pair of opposed outer sidewalls depending outwardly and downwardly from peripheral longitudinal edges of the top wall. Each of the outer sidewalls has a lowermost edge, a plurality of ventilation openings, and an upturned flange projecting from the lowermost edge. The vent has a pair of opposed, integrally-formed end walls which depend from opposite ends of the top wall and which are each formed by a plurality of separate, spaced apart wall segments extending across the end of the top wall in substantially end-to-end single file alignment. Each pair of adjacent wall segments are spaced apart to form an open gap therebetween to enable ready flexing of the vent, and selected ones of the wall segments have an undulating configuration such that they interconnect to the top wall via a sinusoidal shaped juncture.

  • Patent number: 6278381
    Abstract: A fault protective device (48) for limiting the maximum current and voltage applicable to electronic components and wiring (26, 30) located in the fuel tank (10) of an aircraft. Particularly, a fuel gauging system circuit (18) extends from a generator (20) located outside the tank to at least one probe (14) located in the tank and from the probe to instrumentation (24) outside the tank. The device is electrically coupled to the circuit at the tank wall (28) and includes a voltage clamp (50) and series inductor-capacitor resonant circuit (46), so that the resonant circuit provides a low series impedance when applied with a signal at the operating frequency of the input signal applied by the generator but provides a high series impedance when experiencing a signal of a different frequency indicative of a system fault.

  • Patent number: 6274354
    Abstract: Methods for efficient production of recombinant AAV are described. In one aspect, three vectors are introduced into a host cell. A first vector directs expression of cre recombinase, a second vector contains a promoter, a spacer sequence flanked by loxP sites and rep/cap, and a third vector contains a minigene containing a transgene and regulatory sequences flanked by AAV ITRs. In another aspect, the host cell stably or inducibly expresses cre recombinase and two vectors carrying the other elements of the system are introduced into the host cell.

  • Patent number: 6273282
    Abstract: An ergonomically friendly container having hot-fill capabilities is disclosed. The container has a dome with grip surfaces that undergo controlled deformation for accommodating a portion of the volumetric shrinkage due to hot filling, capping and cooling. Preferably, a major portion of each grip surface is circumscribed by a brow rib which prevents unwanted dome distortion while permitting an amount of controlled vacuum absorption. In addition, the container body is provided with vacuum flex panels of at least two different sizes which enable the grip surfaces to be located close to the center of gravity of a filled container to provide balanced pouring of the contents from the container.
