Patent number: 5612082Abstract: Metals are reacted in a first solvent, such as 2-methoxyethanol, to form an initial precursor comprising metal-oxide compounds dissolved in the first solvent. A second solvent, such as xylene, that does not react with the metal is added to the solution and the solution heated to distill away the first solvent and form a final precursor. The final precursor is spin-coated on an integrated circuit substrate then dried and annealed to form a thin film of a metal oxide. For metal oxides including bismuth, the bismuth precursor is added to a cold initial precursor and the final precursor is not heated after the bismuth precursor is added. The second solvent wets the substrate better than the first solvent and has a better viscosity for spin-coating, thus resulting in a denser thin film with fewer imperfections.Type: GrantFiled: July 26, 1994Date of Patent: March 18, 1997Assignees: Symetrix Corporation, Matsushita Electronics CorporationInventors: Masamichi Azuma, Michael C.

Patent number: 5583242Abstract: A method of inhibiting the proliferation of B cells by using inhibitors of phosphotyrosine phosphatase can be used to regulate the immune response and to treat diseases such as leukemias or lymphomas marked by malignant proliferation of B cells. The use of such inhibitors can be combined with radiation, which produces a synergistic effect. Several types of inhibitors can be used, including: (1) compounds comprising a metal coordinate-covalently bound to an organic moiety that can form a five- or six-membered ring; (2) compounds in which vanadium (IV) is coordinate-covalently bound to an organic moiety such as a hydroxamate, .alpha.-hydroxypyridinone, .alpha.-hydroxypyrone, .alpha.-amino acid, hydroxycarbonyl, or thiohydroxamate; (3) coordinate-covalent complexes of vanadyl and cysteine or a derivative thereof; (4) nonhydrolyzable phosphotyrosine phosphatase analogues; (5) phostatin; and (6) 4-(fluoromethyl)phenyl phosphate and esterified derivatives.Type: GrantFiled: May 25, 1995Date of Patent: December 10, 1996Assignee: Bristol-Myers Squibb CompanyInventor: Gary L.

Patent number: 5457218Abstract: Electrochromic coating solutions are prepared by reacting a transition metal with a mixture of hydrogen peroxide and an organic acid. The resulting transition metal-peroxy acid product is esterified by reacting with lower carbon alcohols to produce a peroxyester-transition metal derivative. This derivative in solution in lower carbon alcohols provides a working solution into which a substrate having a conductive surface is preferable dipped and removed at a rate sufficient to give a coating of a desired thickness over the conductive surface. Spray or spin coating can be used to apply the coating to the conductive surface of the substrate. The coating is then dried and is externally fired in an oven to complete the necessary reactions to yield an electrochromic oxide coating having exceptional electrochromic properties.Type: GrantFiled: September 2, 1993Date of Patent: October 10, 1995Assignee: Donnelly CorporationInventors: John P.
