Patent number: 5618978Abstract: A method of producing a choline having a high purity without containing by-products by using a molecule-inclusion complex of the choline as a starting material. A choline inclusion complex without containing by-products is obtained by reacting an aqueous solution of the choline containing, as by-products, those cholines to which are added ethylene oxides with host molecules such as of 1,1'-bis-.beta.-naphthol, and is further reacted with a carbon dioxide gas in order to obtain an aqueous solution of a choline carbonate and/or a choline bicarbonate of a high purity, which is then subjected to the electrolysis using a cation-exchange membrane as a diaphragm, in order to obtain an aqueous solution of the choline of a high purity without containing by-products. The choline that is obtained is a strongly basic compound having a high purity and is very useful as a photoresist-developing solution.Type: GrantFiled: March 26, 1996Date of Patent: April 8, 1997Assignee: Japan Hydrazine Co., Ltd.Inventors: Shunji Hyoda, Youichi Hasegawa, Fumio Toda

Patent number: 5614562Abstract: Organoselenones of the formulaR.sub.1 --Se(O.sub.2)--(CH.sub.2).sub.n --Xwherein R.sub.1 is selected from the group consisting of aryl, vinyl, acetylenyl, and aralkyl, n is an integer equal to 2 to 6 and X is a leaving group selected from the group consisting of halides, sulfonates and selenones; were surprisingly found to be useful as alkylating agents which possessed a high degree of selectivity for nitrogen nucleophiles without the usual increased preference for sulfur nucleophiles. This property allows the effective use of these compounds as anti-cancer alkylating agents suitable for use in drug-resistant cell lines which display either thiol mediated drug resistance or MER(+)-mediated drug resistance. Two methods of synthesizing these compounds are also provided.Type: GrantFiled: December 16, 1992Date of Patent: March 25, 1997Assignee: The University of Sourthern CaliforniaInventors: Colin P.

Patent number: 5568022Abstract: An integrated compliance electrohydraulic servovalve system connected to a load such as a simulated living being to provide more realistic movement thereto. The system includes a pressure transducer for sensing the pressure appearing at the output of the electrohydraulic servovalve and which is applied to an actuator connected to the load. The pressure as sensed is developed into a corresponding electrical signal which is used as a feed back signal to the drive motor of the electrohydraulic servovalve. The actuator position signal is also provided and is summed with the position command input signal to provide the command signal which is also summed with the pressure signal prior to application to the drive motor. The utilization of the pressure feed back signal provides compliance to the over all system resulting in a realistic movement of the simulated living being.Type: GrantFiled: October 16, 1995Date of Patent: October 22, 1996Assignee: HR Textron Inc.Inventor: Stephen J.
