Efficient heating may be provided by solutions involving low resistivity layers that lead currents to the top layer without themselves developing heat to any greater extent. A conduction frame device can be provided beneath the top layer and around the perimeter thereof to provide reliable contact with a backing layer.Type: ApplicationFiled: June 8, 2012Publication date: December 18, 2014Applicant: Avalon Innovation ABInventor: Jan Jäderberg

Patent number: 8906281Abstract: In an imprint method according to one embodiment, a template on which a template pattern is formed is pushed against resist on a substrate to be transferred while the resist is cured in this state. The template is subsequently separated from the cured resist. The template is then degassed from the template pattern surface side between after the template is separated from the cured resist and till the template is pushed against resist at the next shot.Type: GrantFiled: February 22, 2012Date of Patent: December 9, 2014Assignee: Kabushiki Kaisha ToshibaInventors: Masayuki Hatano, Takumi Ota, Yohko Furutono

Patent number: 8905744Abstract: A transport container for use in a device for producing a three-dimensional object of selective solidification of a build-up material deposited in layers, in which the device has a process chamber closed during operation, where the three-dimensional object is produced in layers. The transport container has a container, in which a height-adjustable platform is arranged, on which the three-dimensional object is produced in layers. The process chamber has first and second sections in which the second section can be separated from the first section and operated in a separate state independently from the device and also can be connected to the first section to produce an operating state of the device.Type: GrantFiled: March 31, 2010Date of Patent: December 9, 2014Assignee: Sintermask GmbHInventor: Carl Fruth

Patent number: 8905748Abstract: A compact deformation-based micro-texturing apparatus and method employ flexure bearing houses for rotatably supporting opposite ends of each of a first (e.g. upper) roll and a second (e.g. lower) roll to provide a working roll gap between the rolls, wherein at least one of the rolls has one or more micro surface features to plastically deform a surface of a workpiece deformed by rolling action in the roll gap. An electrical current may be passed through the workpiece to assist micro deformation. A roll gap adjusting device is operably associated with the first and second flexure bearing houses for adjusting the roll gap dimension to the final depth of the micro surface features to be imparted to the surface of the workpiece by the rolling action.Type: GrantFiled: December 15, 2011Date of Patent: December 9, 2014Assignee: Northwestern UniversityInventors: Jian Cao, Rui Zhou, Kornel F.
