Patent number: 8384274Abstract: An apparatus for producing electromagnetic radiation includes a flow generator configured to generate a flow of liquid along an inside surface of an envelope, first and second electrodes configured to generate an electrical arc within the envelope to produce the electromagnetic radiation, and an exhaust chamber extending outwardly beyond one of the electrodes, configured to accommodate a portion of the flow of liquid. In another aspect, the flow generator is electrically insulated. In another aspect, the electrodes are configured to generate an electrical discharge pulse to produce an irradiance flash, and the apparatus includes a removal device configured to remove particulate contamination from the liquid, the particulate contamination being released during the flash and being different than that released by the electrodes during continuous operation.Type: GrantFiled: July 13, 2010Date of Patent: February 26, 2013Assignee: Mattson Technology, Inc.Inventors: David Malcolm Camm, Chee Chin, Rick Doolan, Tony Hewett, Arne Kjorvel, Tony Komasa, Mike Krasnich, Steve McCoy, Joseph Reyers, Igor Rudic, Ludmila Shepelev, Greg Stuart, Tilman Thrum, Alex Viel

Patent number: 7578604Abstract: Disclosed is an intense pulse light device, in which plural divided light filters coated with individually different materials are rotatably and uniformly aligned around a reflection mirror in order to selectively filter lights according to wavelengths thereof, so that it is not necessary to exchange a handle body or filters, thereby improving convenience of use for the IPL device, and in which the loose contact of power lines and signal lines, leakage of cooling water, and penetration of impurities can be prevented, thereby improving reliability of IPL device. A semicircular reflection mirror aligned around a flash lamp installed in a body and a light filter section is aligned around the reflection mirror while forming a predetermined space therebetween. The light filter section is uniformly divided into two or four light filters so as to increase selectivity for the light radiated from flash lamp.Type: GrantFiled: April 2, 2004Date of Patent: August 25, 2009Inventor: Young-Su Lee

Patent number: 7545087Abstract: To devise a small light source device in which breaking of the bulb of the light source lamp can be suppressed and in which breaking of the bulb will not damage the window component, a light source lamp supported in a housing by only one of two hermetically sealed tubes at opposite ends of an arc tube, a cooling rib is mounted on a lead pin in the one of the sealed tubes that faces toward the window component and has a larger dimension in the radial direction than the maximum diameter of the opening edge of the light exit opening in the housing. The cooling rib serves to block bulb fragments and should it contact the peripheral edge area of the light exit opening with its edge that faces the window component, due to its size, neither the lead pin nor the cooling rib will contact the window component.Type: GrantFiled: July 13, 2006Date of Patent: June 9, 2009Assignee: Ushiodenki Kabushiki KaishaInventors: Katsuoki Miyasu, Takehiko Iguchi, Shunichi Morimoto

Patent number: 6621199Abstract: A method and apparatus for producing high intensity electromagnetic radiation are disclosed. The apparatus includes a high intensity arc lamp having an inner envelope cooled by a first flow of liquid along an inside surface of the inner envelope. The arc lamp includes first and second electrodes for generating a high power plasma arc within the inner envelope, the arc emitting the radiation. The apparatus further includes a cooling device for producing a second flow of liquid in contact with an outside surface of the inner envelope. In order to approximate a desired electromagnetic radiation spectrum, the apparatus may further include an energy redistributor for redistributing energy within a first radiation spectrum generated by the arc to produce a second radiation spectrum.Type: GrantFiled: January 21, 2000Date of Patent: September 16, 2003Assignees: Vortek Industries Ltd., Vortex Industries Ltd.Inventors: Dean Allister Parfeniuk, David Malcolm Camm, Johan George Fourie, Roger Housden, Arne Kjørvel, Steven McCoy, Sujay Prasad, Tilman Jochen Thrum

Patent number: 5386170Abstract: An additional capacitance in the form of a molding (12") composed of dielectric material is inserted in an inner space of an ultraviolet light excimer radiator, making it possible to enforce loss-free control of the axial and/or radial distribution of the power consumption and ultraviolet light intensity. In the irradiation of wide substrates such as sheets, papers, and the like coated with paint, lacquers or adhesives, in particular, this measure is advantageous if all the regions of the substrate are to be irradiated with approximately the same dose.Type: GrantFiled: November 13, 1992Date of Patent: January 31, 1995Assignee: Heraeus Noblelight GmbHInventor: Ulrich Kogelschatz

Patent number: 5168194Abstract: A flash light operating in the "pulse and simmer" mode has a cathode and an anode 18 mounted at opposite ends of a transparent envelope 10. The cathode, which may be water cooled, includes a mount 24 and a tip 26 joined to the mount by an undercut neck portion 28. Thus the tip 26 runs at an increased operational temperature due to the reduced thermal conductivity of the neck portion. The ratio of the diameter D of the tip 26 to its axial dimension C from the neck portion 28 may be in the range 0.3 to 0.5.Type: GrantFiled: August 28, 1991Date of Patent: December 1, 1992Assignee: Heraeus Noblelight LimitedInventors: David H. Littlechild, Bernard R. Venn

Patent number: 4477711Abstract: The invention relates to an apparatus to perform plasma welding, by providing a cooling water temperature detector at the inlet side of cooling water in the plasma welding torch, controlling the temperature at the inlet side of the cooling water running into the plasma welding torch at a set temperature of more than 4.degree. C. and less than 18.degree. C., starting a plasma arc when the temperature of the cooling water reaches a specified point after starting to pass the cooling water, and moving the base metals and the torch relatively upon lapse of a specified time allowed to form a keyhole after start of the plasma arc.Type: GrantFiled: October 29, 1981Date of Patent: October 16, 1984Assignee: Kubota Ltd.Inventors: Takao Mihara, Toshiaki Morichika, Shigenori Sone
