摘要:
A method for depositing an in situ doped epitaxial semiconductor layer comprises maintaining a pressure of greater than about 80 torr in a process chamber housing a patterned substrate. The method further comprises providing a flow of dichlorosilane to the process chamber. The method further comprises providing a flow of a dopant hydride to the process chamber. The method further comprises selectively depositing the epitaxial semiconductor layer on single crystal material on the patterned substrate at a rate of greater than about 3 nm min-1.
摘要:
One or more sheets, e.g. two glass sheets heated to their deformation temperature are shaped by positioning the sheets on a sheet supporting surface of an outline mold. The outline mold and press face of a shaping member are moved relative to one another to bias the marginal edge portions of the upper sheet against the press face to establish an enclosure around the peripheral edges of the sheets. Vacuum is applied to the peripheral edges of the sheets to pull the air from between the sheets, and from between the press face and adjacent sheet surface as positive or atmospheric pressure is applied to bottom sheet to move the sheets against the press face. Optionally a vacuum can be pulled through passageways in the press face during the shaping of the sheets and pressurized air moved through the passageways after the sheets are shaped to move the sheets away from the press face.
摘要:
An extruded blow molded bottle comprises a neck portion and a body portion. The body portion comprises a first inner layer and a second layer. The first inner layer comprises a first material selected from a group consisting of polyester, phenoxy type thermoplastics, phenoxy-polyolefin thermoplastic blends, and combinations thereof. The second layer comprises a second material selected from a group consisting of virgin PET, recycled PET, PETG, foam, polypropylene, polyester, polyolefins, phenoxy type thermoplastic, phenoxy-polyolefin thermoplastic blends, regrind scrap materials, and combinations thereof. The second material is different from the first material.
摘要:
A medicament for promoting memory consolidation, which comprises, as an active ingredient, a non-natural retinoid, preferably a retinoid having a basic skeleton comprising an aromatic ring bound with an aromatic carboxylic acid or tropolone by means of a bridging group, more preferably 4-[(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthalenyl)carbamoyl]benzoic acid or 4-[(3,5-bis-trimethylsilylphenyl)-carboxamido]benzoic acid.
摘要:
Disclosed are medical devices having lubricious coatings which are capable of producing magnetic resonance image in the presence of a suitable magnetic field. The medical devices are easy to manipulate in body channels because of reduced friction with tissue surfaces and can be readily visualized in real time, which greatly facilitates the tracking of the medical devices while present within the bodies of humans or animals. The level of magnetic susceptible agent in the coatings of medical devices can be easily controlled by the present invention to give the desired performance. Coating processes to produce these medical devices are also disclosed.
摘要:
The process chamber of a vertical furnace is provided with a closure, or door, comprising an upper and a lower door plate. The upper door plate has a gas exhaust opening proximate its center, thereby allowing for a symmetrical flow of process gases through the process chamber and into the gas exhaust opening. The upper door plate is spaced from the lower door plate to form a sealing chamber, which is purged with inert gas. Optionally, both the gas exhaust opening and the sealing chamber empty into a gas exhaust channel formed inside the upper door plate. The gas exhaust channel leads to an exhaust which exhausts gases from the furnace and separates the flow path of corrosive process gases from surfaces of the lower door plate, which may be formed of relatively easily-corroded metal.

The invention relates to an aqueous foam disinfectant comprised of a special surfactant system, which consists of non-ionic and amphoteric surfactants, and of a synergistic disinfectant constituent, which consists of an antimicrobial agent having amino groups and of at least one additional antimicrobial agent.
摘要:
An immunoadjuvant capable of efficiently exerting a potent adjuvant activity while avoiding conditions undesirable for a living body which contains: (a) a soluble protein (excluding a soluble protein contained in tuberculin); (b) a precipitate due to coacervation of a mucopolysaccharide; and (c) a soluble protein contained in tuberculin which is coprecipitated with the above precipitate.
摘要:
Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von Kohlebürsten, umfassend die Schritte: (a) Herstellung einer pulverförmigen Zusammensetzung, die ein Kohlenstoffpulver und ein pulverförmiges thermoplastisches Bindemittel enthält, (b) Verarbeitung der pulverförmigen Zusammensetzung aus (a) bei einer Temperatur oberhalb der Schmelztemperatur des thermoplastischen Bindemittels, um eine Mischung zu erhalten, die das Kohlenstoffpulver und das aufgeschmolzene thermoplastische Bindemittel enthält, (c) gegebenenfalls Aufmahlen und Absieben der Mischung aus Schritt (b), (d) Pressen der Mischung aus Schritt (b) oder Schritt (c), falls durchgeführt, in eine gewünschte Form und (e) Thermische Behandlung bei einer Temperatur oberhalb des Schmelzpunkts des thermoplastischen Bindemittels, aber unterhalb dessen Zersetzungstemperatur. Die Erfindung betrifft auch nach diesem Verfahren hergestellte Kohlebürsten.
