Patent number: 6824861Abstract: A composite-based rim and methods for manufacturing such a rim are provided. The rim includes multiple fiber-based, co-mingled layers, wherein the strength and/or stiffness of the layers increases from the innermost layer of the rim to the outermost layer of the rim, but where the radial stress and strain generated in the rim decreases from the innermost layer to the outermost layer. Incorporation of this rim into a high stress and strain usage environment, such as a flywheel system, allows the rim to be spun at high speeds in order to generate high levels of kinetic energy while beneficially managing the amount of strain and radial stresses generated within the rim, and, in turn, minimizing or at least controlling the formation and propagation of cracks within the rim.Type: GrantFiled: September 13, 2001Date of Patent: November 30, 2004Assignee: Beacon Power CorporationInventor: Ward R.

Patent number: 6776879Abstract: It is an object of the invention to provide a backing plate used for the sputtering apparatus and a sputtering method which can improve film deposition rate and film quality without increasing the size of the target with respect to the substrate. High sputtering power is applied to a target portion opposite to a location where a thin film is formed on a surface of a substrate, thereby a thin film having even film thickness and film quality can be formed without increasing the size of the target. Further, a cooling medium flow passage can eliminate temperature unevenness caused by different sputtering powers to be applied to a target surface. The problem caused by the temperature rise can be solved and the film deposition speed can be enhanced by increasing the sputtering power which can be applied to the target. Consequently, it is possible to improve productivity of the substrate.Type: GrantFiled: January 28, 2002Date of Patent: August 17, 2004Assignee: Sharp Kabushiki KaishaInventors: Tatsushi Yamamoto, Takamitsu Tadera

Patent number: 6750475Abstract: An oxide film is formed on an insulating substrate by means of a wet type film forming technique such as a sol-gel method, a chemical deposition method or a liquid phase deposition method. Next, the oxide film is patterned according to the shape of interconnections.

Patent number: 6729042Abstract: A method is described for enhancing mass and heat transport of fluids in a fine pore structure through an appropriate modulation of the fluid pressure. For example, in an air drying process for a porous material that contains liquid, the air pressure is modulated throughout the volume of the drying chamber. Alternatively, the fluid pressure is modulated in a process stream. As an example, this method can be used for rapid drying of any open porous substances ranging from small pored materials such as aerogels and xerogels, to larger pored substances or articles such as industrial articles, agricultural articles (e.g., densely stacked vegetables, coffee beans, hops and other grains), paper-based products, thin films, pharmaceuticals, cloth, and clothing.Type: GrantFiled: April 16, 2002Date of Patent: May 4, 2004Assignee: Aspen Systems, Inc.Inventor: Kang P.
