Publication number: 20110037824Abstract: A laser exposure method for performing exposure is provided in which a supporting stage (2) supporting a plurality of objects (workpieces 5) and a laser beam illumination device (3) illuminating the objects while a focus servo control based on reflected light is being effected are moved relative to each other. The method includes a control start step of starting the focus servo control when the laser beam has reached a focus start position (FS) on an object; a control stop step of stopping the focus servo control when the laser beam has reached a focus stop position (FE) on the object; and a retaining step of retaining a position of an optical component (objective lens 35) at a predetermined position for a period until the laser beam starting from the focus stop position (FE) on the object reaches a focus start position (FS) on a subsequent object.Type: ApplicationFiled: March 23, 2009Publication date: February 17, 2011Applicant: FUJIFILM CorporationInventor: Yoshihisa Usami

Publication number: 20110024300Abstract: The present disclosure generally relates to techniques for electro-depositing nano-patterns. More specifically, systems and methods for fabricating periodic structures in complex nano-patterns are described. An electrical signal may be applied to one or more electrodes that are positioned about a surface of a substrate. The periodicity of the deposited pattern may be influenced by one or more parameters associated with an applied electrical signal, including one or more of frequency, amplitude, period, duty cycle, etc. The weight of each deposited line on the substrate may be influenced by the described parameters, and the shape of the pattern may be influenced by the number, shape, and position of electrodes.Type: ApplicationFiled: July 30, 2009Publication date: February 3, 2011Inventor: Ezekiel KRUGLICK

Publication number: 20100316686Abstract: The present invention relates generally to an antibacterial coating which is composed of silver, to medical tools and to implants comprising such a coating and to a method as well to an apparatus for the production of such a coating. The medical tools or the dental or orthopaedic implant comprises a metal or metal alloy having a treated surface wherein the treated surface is at least partially converted to an oxide film by plasma electrolytic oxidation using a colloid-dispersed system and wherein the converted surface is partially covered by islands formed by colloid-dispersed silver-particles of the colloid-dispersed system. An Ag—TiO2 coating shows excellent properties in terms of antibacterial efficacy (even against multi-resistant strains), adhesion and biocompatibility. The life-time of an implant in a human body is increased. The antibacterial coating can be used in the field of traumatology, orthopaedic, osteosynthesis and/or endoprothesis, especially where high infection risk exists.Type: ApplicationFiled: June 2, 2010Publication date: December 16, 2010Applicant: AAP BIOMATERIALS GMBHInventors: Elvira Dingeldein, Cyrille Gasqueres, Frank Witte, Amir Eliezer

Patent number: 7802357Abstract: A method of forming a plating film capable of improving magnetic properties is provided. A photoresist pattern, having a first opening with an aspect ratio greater than 1 and a second opening with an aspect ratio smaller than that of the first opening, is formed on a surface of a substrate. A seed film is formed to cover an exposed surface of the substrate in the openings and an inner wall of the photoresist pattern in the openings. On the seed film in the openings, the plating film of magnetic material is deposited such that the first opening is filled under application of a magnetic field in the direction intersecting the surface of the substrate, and the second opening is filled under application of the magnetic field in the direction along the surface of the substrate.Type: GrantFiled: July 12, 2007Date of Patent: September 28, 2010Assignee: TDK CorporationInventor: Akifumi Kamijima

Publication number: 20100089760Abstract: A method for making a gasket (32) for an internal combustion engine (20) includes forming a generally annual stopper (38) on a metallic gasket body (40) through the process of electrochemical deposition. An electrolytic cell is completed with the gasket body (40) forming a cathode. The stopper (38) is formed with a contoured compression surface (42) by selectively varying the electrical energy delivered to selected electrodes (70) over time. Electrolyte (48) rich with metallic ions is pumped at high speed through the inter-electrode gap. A PC controller (82) switches selected electrodes (70) ON at certain times, for certain durations, which cause metallic ions in the electrolyte (48) to reduce or deposit onto the gasket body (40), which are built in columns or layers into a three-dimensional formation approximating the target surface profile (106) for the compression surface (42). The subject method for building a three-dimensional formation can be applied to work parts other than cylinder head gaskets (32).Type: ApplicationFiled: December 18, 2009Publication date: April 15, 2010Inventor: Yuefeng Luo
