Patent number: 9984797Abstract: A high voltage impedance device with surface leakage proof configuration is applied in a divider. Aforementioned divider is assembled by a high impedance element, an inner case body and an outer case body. The high impedance element is sealed in the inner case body and a closed interlayer between the inner case body and the outer case body is filled with noble gas as an insulating layer. While the high impedance element is applied in high voltage, the closed interlayer can prevent the current-leakage from forming impedance paralleled with the high impedance element.

Patent number: 7341802Abstract: A feedthrough is insulated and hermetically sealed by brazing a ceramic disk to a case cover and by brazing the top surface of the ceramic disk to the bottom surface of a feedthrough pinhead. Using this technique instead of forming a compression seal, the surface area for bonding is increased, increasing bond strength. The ceramic disk electrically insulates the feedthrough pin from the cover, and provides a large surface area for mechanically sealing the cell with the braze. Considering the small size of many cells, this increased surface area is important for getting a good seal and increasing bond strength. This design also creates a longer fluid path, providing greater hermeticity. Furthermore, a greater range of component material combinations is available because CTE compatibility limitations of the feedthrough pin, cover, and insulator are minimized. This feedthrough is applicable to broad array of applications and numerous material combinations.Type: GrantFiled: March 25, 2004Date of Patent: March 11, 2008Assignee: Quallion LLCInventors: Naoki Ota, Hiroshi Nakahara, David L.

Patent number: 7145076Abstract: A feedthrough terminal pin assembly includes an outer ferrule hermetically sealed through a braze joint to an insulator seated within the ferrule is described. The insulator is also hermetically brazed to at least one terminal pin. The terminal pin is provided with a braze retention structure such as an annular groove that prevents braze material from filleting past the groove. Similarly, either the ferrule or the insulator is provided with a retention structure such as an annular groove that prevents braze material spill out from the insulator/ferrule interface. In that manner, the braze retention structures keep braze material from accumulating in unwanted areas where it could adversely affect hermeticity as well as proper attachment of an EMI filter to the feedthrough assembly.Type: GrantFiled: February 7, 2006Date of Patent: December 5, 2006Assignee: Greatbatch, Inc.Inventors: Scott Knappen, Robert Naugler, Haytham Hussein, Thomas Shipman, Richard Brendel, Christine Frysz

Patent number: 7107676Abstract: Manufacturing equipment and manufacturing process steps that improve upon prior art processes for the manufacturing of filament tube and arc tube light sources, their components and subassemblies, and lamps employing said light sources. A double ended, tipless filament tube or arc tube light source incorporates a drawn-down tubular body, and one piece foliated leads with spurs for process handling and for spudding into a filament with stretched-out legs. Bugled ends on the body provide a novel cutoff means, facilitate a flush-fill finishing process, and enhance mounting and support of the light sources in lamps. The foliated leads are made from a continuous length of wire in a process including foil hammering and two-bath AC electrochemical etching. Cost-reduced light source and lamp production enables affordable household consumer lamps, even when containing two series-connected halogen filament tubes.Type: GrantFiled: November 5, 2003Date of Patent: September 19, 2006Inventor: Elmer G. Fridrich

Patent number: 6958446Abstract: A solder joint or seal attaching components having dissimilar coefficients of thermal expansion is made thin (e.g., less than 20 ?m and preferably about 5 ?m) and of a solder such as an indium-based solder that has a tendency to creep. The solder is toroidal or otherwise shaped to avoid tensile stress in the solder. Axial shearing stress in the solder causes reversible creep without causing failure of the joint or seal. In one embodiment, a toroidal solder seal has a diameter, a footprint, and a thickness in approximate proportions of 5000:200:1.Type: GrantFiled: April 17, 2002Date of Patent: October 25, 2005Assignee: Agilent Technologies, Inc.Inventors: Giles Humpston, Yoshikatsu Ichimura, Nancy M.
