Patent number: 6655002Abstract: A microactuator, or micromotor, (60) and method for making it are presented such that a symmetrical build up of material is performed on opposite sides of a substrate. This reduces mechanical stresses in the device. In its construction, respective layers of circuit portions (108, 110) are built on each side of the structure, thereby eliminating the need to stack complex patterns. Stacking one complex pattern on top of a similar pattern is difficult because the surface, which is the base for subsequent layers, is not flat. The photolithography process that forms these patterns is not very forgiving to non-flat surfaces. Avoiding the stacked layers also allows thicker conductors to be considered for each circuit. Thicker circuits increase current carrying capacity, which in one of the key variables increase the power of the micromotor.Type: GrantFiled: June 28, 2000Date of Patent: December 2, 2003Assignee: Texas Instruments IncorporatedInventors: Peter J. Maimone, Tsen-Hwang Lin, Kurt P. Wachtler

Patent number: 6620530Abstract: A spin valve structure and a method for manufacturing it are described. The spin valve uses a modified pinned layer that consists of two cobalt iron layers separated by a layer of either ruthenium, iridium, or rhodium. A key feature of the invention is that this spacer layer is significantly thinner (typically 3-4 Angstroms) than similar layers in prior art structures. Normally, when such thin spacer layers are used, annealing fields in excess of 20,000 Oersted are needed to cause the two cobalt iron layers to become antiparallel. The present invention, however, teaches that much lower annealing fields (spanning a limited range) may be used with equal effect. The result is that a very high internal pinning field is created giving devices of this type greater pinned layer stability and reduced pinning reversal. These devices also exhibits a minimum amount of open looping in their hysteresis curves.Type: GrantFiled: January 26, 2001Date of Patent: September 16, 2003Assignee: Headway Technologies, Inc.Inventors: Min Li, Cheng T.

Patent number: 6528119Abstract: The invention provides an improved paper coating composition for ink jet printing applications. The composition contains from about 2 to about 1 parts by weight polyvalent metal salt, from about 0 to about 30 parts by weight deionized water, an effective amount of cationic amine polymer and surfactant and from about 35 to about 60 parts by weight of an ink penetrant promoter selected from the group consisting of 1,2-propanediol, dipropylene glycol and mixtures of 1,2-propanediol and dipropylene glycol. Since the composition is free from ethylene glycol components, the composition is safer to use and less harmful to humans and the environment. The composition has also been found to provide improved ink drying with less bleeding or smearing of image.Type: GrantFiled: January 18, 2000Date of Patent: March 4, 2003Assignee: Lexmark International, Inc.Inventor: David Starling MacMillan

Patent number: 6524714Abstract: A heat treatable coated article including a solar management layer for reflecting infrared (IR) or the like, is provided between a substrate and an overlying dielectric layer. An underlying dielectric layer between the substrate and solar management layer is optional. In certain embodiments, the solar management layer may include NiCrNx while the dielectric layer(s) may include a nitride such as silicon nitride. By nitriding the solar management layer, it has been found that the resulting coated article is more color stable upon heat treatment (HT). For example, the coated article may have a &Dgr;E* value (transmissive and/or glass side reflective) of no greater than 5.0, more preferably no greater than 4.0, and most preferably no greater than 3.0. Coated articles herein may be used in the context of insulating glass (IG) window units, vehicle windows, or the like.Type: GrantFiled: May 3, 2001Date of Patent: February 25, 2003Assignee: Guardian Industries Corp.Inventors: George Neuman, Grzegorz Stachowiak, Hong Wang

Publication number: 20030035906Abstract: A transparent electrically conductive device which includes an indium tin oxide film is improved by providing an indium tin oxide film which contains a graded stack of individual indium tin oxide layers wherein the atomic percent of tin in the layers can be individually selected. Each indium tin oxide layer of the film contains 1-99 atomic percent tin. Each layer is made by a physical vapor deposition process or by sputter coating. Preferably the film which contains a plurality of indium tin oxide layers is applied to a transparent flexible substrate such as a polymeric sheet. Optional primer layers, hardcoat layers and topcoat layers may be included in the device.Type: ApplicationFiled: May 9, 2001Publication date: February 20, 2003Inventors: Hassan Memarian, Hitesh Patel
