20090235709 | Non-planar sputter targets having crystlallographic orientations promoting uniform deposition - A non-planar sputter target having differing crystallographic orientations in portions of the sputter target surface that promote more desirable deposition and density patterns of material sputtered from the target surface onto a substrate. A closed dome end of the sputter target is comprised of a first crystallographic orientation and sidewalls of the sputter target are comprised of a crystallographic orientation different from that of the dome. The sputter target is formed, preferably by hydroforming or other metal working techniques, in the absence of annealing. The hydroforming manipulations result in the different crystallographic orientations while minimizing, or ideally omitting, the application of heat. Quick and cost effective non-planar sputter targets that are easily repeatably producable are achievable as a result. | 09-24-2009 |
20100037670 | Gravity Fill System with Pressure Check Valve - A hydroform die includes a plurality of seal units to provide fluid to die cavities. The plurality of seal units each define a piston cylinder. A piston is located within the cylinder and is selectively moveable between an open and a closed position. Additionally, the piston at least partially defines a valve chamber located on a first side of the piston and a piston chamber located on a second side of the piston. A piston fluid passage is defined by the piston to fluidly connect the valve chamber and the piston chamber. | 02-18-2010 |

20130160512 | APPARATUS AND METHOD FOR STENT SHAPING - An apparatus for crimping a radially expandable stent includes a pressure vessel, shaping balloon, and mandrel. The mandrel is configured to slidingly receive a stent thereon, and to be slidingly advanced into the pressure vessel. The shaping balloon is inflated to radially compress the stent onto the form of the mandrel; such compression need not be uniform. Pressurization of the shaping balloon facilitates the expansion of the balloon to achieve compression of the stent, with depressurization of the shaping balloon causing the balloon to return to an unexpanded state. | 06-27-2013 |
