Publication number: 20230268167Abstract: A plasma chamber for a UV light source includes a plasma generation region that defines a plasma confinement region. A port is positioned adjacent to a side of the plasma generation region that allows generated light to pass out of the chamber. A high voltage region is coupled to the plasma generation region. A grounded region is coupled to the high voltage region that defines an outer surface configured to be coupled to the ground and is dimensioned for receiving a surrounding inductive core. A width of the high voltage region is greater than the width of the grounded region.Type: ApplicationFiled: February 21, 2022Publication date: August 24, 2023Applicants: Hamamatsu Photonics K.K., Energetiq Technology, IncInventors: Stephen F. Horne, Kosuke Saito, Wolfram Neff, Robert M. Grzybinski, Michael J. Roderick

Patent number: 7410509Abstract: A capacitor is described. the capacitor includes a casing; a cathode of an active material of at least an oxide of a first metal provided on a substrate, wherein the active material is characterized as being of a substantially homogeneous coating formed by sputtering a target of the first metal in a vacuum chamber; an anode spaced from the cathode coating; and an electrolyte in contact with the cathode coating and the anode. The casing contains the anode, the cathode and the electrolyte. A method and apparatus for providing the sputtered coating is also disclosed.Type: GrantFiled: January 16, 2006Date of Patent: August 12, 2008Assignee: Greatbatch Ltd.Inventors: Doug Eberhard, Barry Muffoletto, Wolfram Neff

Publication number: 20080013257Abstract: An anode for an electrolytic capacitor is described. The anode is of a valve metal in powdered form, for example tantalum powder, that has been pressed into a pellet and sintered under a vacuum at high temperatures. Preferably, a poly(alkylene)carbonate binder is used to promote cohesion with the pressed powder body. The binder adds green strength to the pressed body and helps with powder flow before pressing. The poly(alkylene)carbonate binders are superior in that they leave virtually no residual carbon behind when burnt out during the sintering process. The pressed valve metal powder structure is then anodized to a desired voltage in a formation electrolyte to form a continuous dielectric oxide film on the sintered body as well as a terminal lead/anode lead weld extending therefrom.Type: ApplicationFiled: July 17, 2007Publication date: January 17, 2008Applicant: Greatbatch Ltd.Inventors: Keith Seitz, Ashish Shah, Barry Muffoletto, Wolfram Neff, Douglas Eberhard

Publication number: 20050079620Abstract: Methods for testing the hermeticity of casings for power sources intended to power implantable medical device by sensing the presence of vapors escaping from an electrolyte contained therein are described. More broadly, the present leak detection methods are applicable to any sealed enclosure having a first part sealed to a second part with a liquid contained therein. The liquid need not occupy the entire volume of the enclosure, but must contain at least one component having a vapor pressure at 25° C. of more than about 0.1 mm Hg. This component can assist in the functioning of the device such as an electrolyte, or be added for the sole purpose of leak detection.Type: ApplicationFiled: October 11, 2004Publication date: April 14, 2005Inventors: Douglas Eberhard, Barry Muffoletto, Wolfram Neff
