Title: Method for manufacturing superconducting thin film formed of oxide superconductor having non superconducting region in it, method for manufacturing superconducting device utilizing the superconducting thin film and superconducting thin film manufactured thereby
Inventor: TANAKA SO
IPC: H01L39/14
Filed: 1992-08-27
Abstract: For manufacturing a superconducting thin film having at least one non-superconducting region at and near its surface portion, an oxide superconductor thin film is formed on a surface of the substrate. The oxide superconductor thin film is heated in high vacuum environment so that oxygen of the oxide superconductor crystals escapes from the surface of the oxide superconductor thin film and a surface portion of the oxide superconductor thin film having a substantial thickness changes into non-superconducting layer of a compound oxide which is composed of the same constituent elements as those of the oxide superconductor but includes the oxygen amount less than that of the oxide superconductor and a thin superconducting channel is formed under the non-superconducting layer.  A portion of the non-superconducting layer, which will become the non-superconducting region is selectively masked, and heated in an oxidation atmosphere so that oxygen penetrates into the non-superconductor layer from exposed surface and the compound oxide of the exposed portion of the non-superconductor layer changes into the oxide superconductor which is electrically connected to the superconducting channel.

Title: Preparation of edta
Inventor: PARKER BRIAN A
IPC: C07C229/16
Filed: 1992-12-11
Abstract: ABSTRACT Synthesis of ethylenediaminetriacetic acid (ED3A) or its salts is disclosed. A salt of N,N'-ethylenediaminediacetic acid (ED2AH2) is condensed with formaldehyde to form a stable 5-membered ring intermediate. The addition of cyanide across this cyclic material forms ethylenediamine N,N'-diacetic acid-N'-cyanomethyl or salts thereof (mononitrile-diacid). The nitrile in aqueous solutions may be spontaneously cyclized to form 2-oxo-1,4-piperazinediacetic acid (3KP) or salts thereof, which is the desired cyclic intermediate. In the presence of excess base, salts of ED3A are formed in excellent yield and purity. Alternatively, the starting material is ED2AHaXb, where x is a base cation, e.g., an alkali or alkaline earth metal, a is 1 to 2, and b is 0 to 1 in aqueous solutions. The reaction mixture also can be acidified to ensure complete formation of carboxymethyl-2-oxopiperazine (the lactam) prior to the reaction. Formaldehyde is added, essentially resulting in the hydroxymethyl derivative. On the addition of a cyanide source, 1-cyanomethyl-4-carboxymethyl-2-ketopiperazine (mononitrile diacid) or a salt thereof is formed. Upon the addition of any suitable base or acid, this material may be hydrolyzed to 3KP. The addition of a base will open this ring structure to form the salt of ED3A.
