Patent number: 12156322Abstract: A method and apparatus for generating light includes a chamber having a high voltage region, a low voltage region, and a plasma generation region that defines a plasma confinement region. A magnetic core is positioned around the chamber and is configured to generate a plasma in the plasma confinement region. A switched power supply includes a DC power supply and a switched resonant charging circuit that together generate a plurality of voltage pulses at the output causing a plurality of current pulses to be applied to the power delivery section around the magnetic core so that at least one plasma loop is established around the magnetic core that confines plasma in the plasma confinement region, thereby forming a magnetically confined Z-pinch plasma. Light generated by the Z-pinch plasma propagates out of a port in the light source.Type: GrantFiled: December 8, 2022Date of Patent: November 26, 2024Assignees: Hamamatsu Photonics K.K., Energetiq Technology, Inc.Inventors: Frederick Marvin Niell, III, Donald K. Smith, Matthew M. Besen, Stephen F. Horne, David B. Reisman, Daniel J. Arcaro, Michael J. Roderick

Patent number: 11391420Abstract: A light string of ornamental piece is provided wherein each ornamental piece includes electrical wiring that provides electrical power to a light element for each ornamental piece. The ornamental piece includes a shroud that is made up of mated shroud halves that are constructed and arranged to receive the electrical wiring and capture the light element therebetween. The shroud halves are each formed with a decorative base and integral neck having a top surface through which the electrical wiring extends. The light element is supported so as to be disposed within the base of the shroud so as to illuminate the base of the shroud.Type: GrantFiled: November 12, 2020Date of Patent: July 19, 2022Assignee: Fourstar Group Inc.Inventors: Huang Cheng Chung, Xu Xiang Yang

Patent number: 9651595Abstract: The invention refers to a chamber for measurements of electrical properties of reactive powder or liquid samples, allowing the measurement of various electrical parameters to be carried out. The present invention provides the chamber in two variants of embodiment: the multiple use chamber and the single use chamber. The construction of the chamber provides the possibility of carrying out the measurements with the sample placed directly between parallel active surfaces of the electrodes placed coaxially and sliding in a precise manner in to a thin-walled cylinder made of insulating material providing electric insulation. Elements remaining in contact with the sample are made of chemically inert materials. Additionally, a module containing a pair of the electrodes and the cylinder made of insulating material is detachable from the rest of device elements, that enables its loading and hermetic closure in a glovebox filled with inert gas.Type: GrantFiled: October 22, 2012Date of Patent: May 16, 2017Assignee: UNIWERSYTET WARSZAWSKIInventors: Karol Jan Fijalkowski, Rafal Jurczakowski

Patent number: 7884546Abstract: An electrodeless discharge lamp apparatus is provided which is increased in heat dissipation, making it possible to adapt to an increase in output of the apparatus. The electrodeless discharge lamp apparatus comprises a bulb containing a discharge gas and a coupler accommodated in a cavity formed in the bulb for generating a high frequency electromagnetic field. The coupler has: an induction coil; a core inserted into the coil; a heat conductor for conducting heat generated from the coil and the core; and a bobbin made of resin which accommodates the core and the heat conductor therein, and which has the coil wound therearound. The bobbin is designed to be separated in a radial direction of the coil, so that it is possible to separately mold the respective parts of the bobbin.Type: GrantFiled: September 28, 2005Date of Patent: February 8, 2011Assignees: Panasonic Electric Works Co., Ltd., Ikeda Electric Co., Ltd.Inventors: Hiroshi Ogasawara, Hiroshi Miyasaki, Hidenori Kakehashi, Keisuke Harada, Yoshinobu Shibata

Patent number: 7307375Abstract: An apparatus for producing light includes a chamber that has a plasma discharge region and that contains an ionizable medium. The apparatus also includes a magnetic core that surrounds a portion of the plasma discharge region. The apparatus also includes a pulse power system for providing at least one pulse of energy to the magnetic core for delivering power to a plasma formed in the plasma discharge region. The plasma has a localized high intensity zone.Type: GrantFiled: July 9, 2004Date of Patent: December 11, 2007Assignee: Energetiq Technology Inc.Inventors: Donald K. Smith, Stephen F. Horne, Matthew M. Besen, Paul A. Blackborow
