Publication number: 20110018182Abstract: An apparatus comprises a housing, a core located in the housing, a coil unit associated with the core and located in the housing, and a backing plate made of a high-permeability material. The apparatus may be used for generating high clamping forces between materials that are interposed between the core and the backing plate such that manufacturing operations can be carried out. The core has a cross section with an elongate shape. The coil unit is configured to generate magnetic fields and has the elongate shape.Type: ApplicationFiled: May 4, 2010Publication date: January 27, 2011Applicant: THE BOEING COMPANYInventors: Arthur C. Day, Samuel Roderick Dobbs, Branko Sarh, John Walter Hall, Kyle Paul Larson

Patent number: 7862050Abstract: A process and apparatus for centering accurately and speedy a workpiece on a magnet chuck mounted on a work spindle. A pair of action pads spaced away from one another comes into engagement with the workpiece attracted to the work spindle, thereby performing the centering operation. The action pads are mounted on a support plate that can freely turn on a fulcrum. As the fulcrum makes head towards a rotational center of the magnet chuck, the action pads comes into abutment in a rocking manner against the workpiece that is held at off-center relation in the chuck, thereby compensating the off-center relation to keep a center of the workpiece in alignment with the rotational center of the chuck.Type: GrantFiled: March 12, 2007Date of Patent: January 4, 2011Assignee: Nippon Thompson Co., Ltd.Inventor: Naoki Koshino
