Publication number: 20110033755Abstract: It has long been recognized that replacing the Li intercalated graphitic anode with a lithium foil can dramatically improve energy density due to the dramatically higher capacity of metallic lithium. However, lithium foil is not electrochemically stable in the presence of typical lithium ion battery electrolytes and thus a simple replacement of graphitic anodes with lithium foils is not possible. It was found that diblock or triblock polymers that provide both ionic conduction and structural support can be used as a stable passivating layer on a lithium foil. This passivation scheme results in improved manufacture processing for batteries that use Li electrodes and in improved safety for lithium batteries during use.Type: ApplicationFiled: April 21, 2009Publication date: February 10, 2011Applicant: Seeo, IncInventors: Hany Basam Eitouni, Mohit Singh, Nitash Pervez Balsara, William Hudson, Ilan R.

Patent number: 6926924Abstract: A metal-composite hose having a wall including an innermost metal layer and a resin layer surrounding it, in which the metal layer has at each end portion of the hose an inner surface covered with a resin layer, an elastic rubber layer, or both. A process for manufacturing a metal-composite hose includes: forming a metal layer; covering the metal layer with an elastic rubber layer, if required; and after masking a specific portion of the metal layer, forming a thermoplastic resin layer thereon by powder or spray coating. The hose is preferably a corrugated one. It has high fluid impermeability, flexibility and strength, as well as high metal-rust resistance and sealing property at both ends.Type: GrantFiled: April 17, 2002Date of Patent: August 9, 2005Assignee: Tokai Rubber Industries, Ltd.Inventors: Kazutaka Katayama, Motoshige Hibino, Atsuo Miyajima, Hiroaki Ito

Patent number: 6896935Abstract: A method of forming a coating on an inner periphery of a tube with a cylindrical barrel, a mouth on one axial end of the barrel, and a shoulder located between the barrel and the mouth. The method involves holding the tube, and subsequently jetting powder into the tube from a spray gun, through a bottom side opening on the other axial end of said barrel. A first passage guides to the spray gun a first air stream together with the powder. A second passage feeds to the spray gun a second air stream with the powder. A third passage suction collects surplus powder through the tube mouth. A fourth passage suction collects surplus powder through the bottom side opening of the tube. At least one of the passages is subject to a feedback control such that flow rate and/or internal pressure therein are maintained at target levels.Type: GrantFiled: February 5, 2003Date of Patent: May 24, 2005Assignee: Taisei Kako Co., Ltd.Inventors: Taizo Kimura, Naoki Fujisawa

Patent number: 6811805Abstract: The invention provide a method for applying a coating to an ophthalmic lens or a mold for making the ophthalmic lens or a medical device other than ophthalmic lens. The method comprises spraying at least one layer of a coating liquid onto an ophthalmic lens using a spraying process selected from the group consisting of an air-assisted atomization and dispensing process, an ultrasonic-assisted atomization and dispensing process, a piezoelectric assisted atomization and dispensing process, an electro-mechanical jet printing process, a piezo-electric jet printing process, a piezo-electric with hydrostatic pressure jet printing process, and a thermal jet printing process. The coating can comprise a property/functionality pattern or a color image or combination of both.Type: GrantFiled: May 22, 2002Date of Patent: November 2, 2004Assignee: Novatis AGInventors: Allen Gilliard, Lynn Cook Winterton, Rafael Victor Andino, John Lally

Patent number: 6790472Abstract: A method of filming a luminescent screen is disclosed which improves the light output of CRTs that contain printed phosphor lines. The method incorporates both the application and film formulation requirements and optionally includes in-line diagnostic techniques. The novel film formulation contains a lacquer and solvents, wherein one of the solvents is a non-solvent for the lacquer. The optional diagnostic technique include surface gloss measurements to characterize and monitor the process and provide predictive capability of CRT performance with respect to light output.Type: GrantFiled: October 25, 2001Date of Patent: September 14, 2004Assignee: Thomson Licensing S. A.Inventors: Victoria Ann Rebar, Bhanumurthy Venkatrama Subrahmanya Gunturi

Patent number: 6720079Abstract: The invention concerns a polyester bearing tertiary carboxyl groups, characterised in that it consists of: (a) 8.1 to 35 moles of an aliphatic or cycloaliphatic of a polyol; (b) 9.1 to 36 moles of an aliphatic, cycloaliphatic or aromatic polycarboxylic acid; (c) 1.6 to 2.8 moles of an aliphatic, cycloaliphatic or aromatic compound comprising a tertiary carboxyl group and either a primary or secondary carboxyl group, or a primary or secondary hydroxyl group. Said polyester is prepared in several steps, the first steps consisting in the preparation of a polyester by condensation between (a) an aliphatic or cycloaliphatic polyol, and (b) an aliphatic, cycloaliphatic or aromatic polycarboxylic acid, the final step consisting in condensing said polyester with (c) an aliphatic, cycloaliphatic or aromatic compound comprising a tertiary carboxyl group and either a primary or secondary carboxyl group, or a primary or secondary hydroxyl group.Type: GrantFiled: August 27, 2002Date of Patent: April 13, 2004Assignee: UCB, S.A.Inventors: Luc Moens, Kris Buysens, Daniel Maetens

Patent number: 6713134Abstract: There is provided an apparatus for spin-coating a semiconductor substrate, including (a) a rotary table rotatable in opposite directions, (b) a nozzle dropping coating material onto a semiconductor substrate lying on the rotary table, (c) an electrode having a ring-shaped cross-section and disposed around the rotary table, and (d) a power source applying a voltage to the electrode, the voltage having an electric polarity opposite to an electric polarity of the coating material. Coating material dropped onto the semiconductor substrate is attracted to an electric field generated by the electrode around the semiconductor substrate. Hence, the coating material is not concentrated around a center of the semiconductor substrate, but is facilitated to uniformly spread over the semiconductor substrate, ensuring formation of a coating layer having a uniform thickness.Type: GrantFiled: May 14, 2001Date of Patent: March 30, 2004Assignee: NEC Electronics CorporationInventor: Shuichi Furuoya
