Patent number: 6723450Abstract: A magnetic recording medium for data storage uses a magnetic recording layer having at least two ferromagnetic films with different remanent magnetization-thickness (Mrt) values that are coupled antiparallel across a nonferromagnetic spacer film predominantly by the dipole field (Hd) from the grains of the higher-Mrt ferromagnetic film. The material compositions and thicknesses of the ferromagnetic films and the nonferromagnetic spacer film are selected so that Hd predominates over any antiferromagnetic exchange coupling field (Haf) and is greater than the coercive field of the lower-Mrt ferromagnetic film. As a result, the magnetizations of the two ferromagnetic films are antiparallel in the two remanent magnetic states, and thus the net remanent magnetization-thickness product (Mrt) of the recording layer is the difference in the Mrt values of the two ferromagnetic films.Type: GrantFiled: March 19, 2002Date of Patent: April 20, 2004Assignee: Hitachi Global Storage Technologies Netherlands B.V.Inventors: Hoa Van Do, Mary F.

Patent number: 6541133Abstract: A layer stack for the surface coating of transparent substrates, in particular panes of glass, has at least one metal oxide composite layer produced by reactive cathodic sputtering and contains Zn oxide and Sn oxide. Relative to the total amount of metal, this metal oxide composite layer contains from 0.5 to 6.5% by weight of one or more of the elements Al, Ga, In, B, Y, La, Ge, Si, P, As, Sb, Bi, Ce, Ti, Zr, Nb and Ta. In a layer stack which has a silver layer as a functional layer, the metal oxide composite layer may be used as an upper and/or lower antireflection layer, as a diffusion barrier layer, as a sublayer of an antireflection layer and/or as an upper cover layer.Type: GrantFiled: June 22, 2000Date of Patent: April 1, 2003Assignee: Saint-Gobain VitrageInventors: Heinz Schicht, Uwe Schmidt, Wilfried Kaiser, Herbert Schindler, Rolf Pfannkuchen

Patent number: 6495263Abstract: A heat treatable coated article including an infrared (IR) reflecting layer (e.g., of or including Ag), the coated article being able to attain a &Dgr;E*ab (glass side) no greater than about 3.0, more preferably no greater than 2.5, and even more preferably no greater than 2.0, following or due to heat treatment (e.g., thermal tempering). Accordingly, low-E (i.e., low emissivity) coated articles of certain embodiments of this invention appear from the glass side thereof visually similar to the naked eye both before and after heat treatment. Coated articles herein may be used in the context of insulating glass (IG) window units, vehicle windshields, or any other suitable applications. In certain embodiments of this invention, an exemplary layer stack includes: glass/Si3N4/NiCr/Ag/NiCr/Si3N4. Other materials may instead be used without departing from the scope and/or spirit of the instant invention which is a low-E matchable product.Type: GrantFiled: February 8, 2001Date of Patent: December 17, 2002Assignee: Guardian Industries Corp.Inventor: Grzegorz Stachowiak

Patent number: 6488862Abstract: Copper can be pattern etched at acceptable rates and with selectivity over adjacent materials using an etch process which utilizes a solely physical process which we have termed “enhanced physical bombardment”. Enhanced physical bombardment requires an increase in ion density and/or an increase in ion energy of ionized species which strike the substrate surface. To assist in the removal of excited copper atoms from the surface being etched, the power to the ion generation source and/or the substrate offset bias source may be pulsed. In addition, when the bombarding ions are supplied from a remote source, the supply of these ions may be pulsed. Further, thermal phoresis may be used by maintaining a substrate temperature which is higher than the temperature of a surface in the etch chamber.Type: GrantFiled: October 27, 1999Date of Patent: December 3, 2002Assignee: Applied Materials Inc.Inventors: Yan Ye, Diana Xiaobing Ma, Gerald Yin

Patent number: 6485846Abstract: A component for a gauge comprising a bourdon tube having a first end and a second end. A socket is joined to the first end of the bourdon tube and a closure member is joined to the second end of the bourdon tube. At least one of the bourdon tube and the closure member comprises a copper nickel alloy and/or the socket comprises a nickel silver alloy. In addition, a low temperature soldering material, such as a tin-bismuth soldering material, was used to affix the socket to the bourdon tube and the closure member to the bourdon tube. Preferably, the components contain substantially no free copper. Such a component resists corrosion, especially corrosion formed when certain fluids are used with such components.Type: GrantFiled: September 29, 2000Date of Patent: November 26, 2002Assignee: Ametek, Inc.Inventors: Alexander L.

Patent number: 6472049Abstract: Reproducible texturing of magnetic recording media is enhanced by sputtering a buffer layer, such as Ni—P, on a nonmagnetic substrate, prior to sputtering a textured bump layer. A magnetic recording medium comprising a sputter textured metal layer and high coercivity is achieved by employing an underlayer, such as NiAl or FeAl, preferably a composite underlayer containing a chromium or chromium-alloy layer and a NiAl layer, on the sputter textured layer. Advantageously, the buffer layer, underlayer, textured bump layer, magnetic layer and carbon overcoat can be sputter deposited in a single apparatus.Type: GrantFiled: February 21, 2001Date of Patent: October 29, 2002Assignee: Seagate Technology LLCInventors: Xing Song, Ga-Lane Chen, Charles Leu, Qixu Chen
