Patent number: 7037160Abstract: A color cathode-ray tube (CRT) having an evacuated envelope with an electron gun therein for generating at least one electron beam is provided. The envelope further includes a faceplate panel having a luminescent screen with phosphor elements on an interior surface thereof. A focus mask, having a plurality of spaced-apart first conductive strands, is located adjacent to an effective picture area of the screen. The spacing between the first conductive strands defines a plurality of apertures substantially parallel to the phosphor elements on the screen. Each of the first conductive strands has a substantially continuous insulating material layer formed on a screen facing side thereof. A plurality of second conductive wires are oriented substantially perpendicular to the plurality of first conductive strands and are bonded thereto by the insulating material layer. The insulating material layer comprises a low porosity lead-zinc-borosilicate glass.Type: GrantFiled: June 22, 2004Date of Patent: May 2, 2006Assignee: Thomson LicensingInventors: Attiganal Narayanaswamy Sreeram, Leszek Hozer

Patent number: 6653741Abstract: A thermal interface material for use in electronic packaging, the thermal interface material comprises a solder with relatively high heat flow characteristics and a CTE modifying component to reduce or prevent damage due to thermal cycling. The thermal interface material comprises an active solder that contains indium and an intrinsic oxygen getter selected from the group consisting of alkali metals, alkaline-earth metals, refractory metals, rare earth metals and zinc and mixtures and alloys thereof. Lastly, damage due to an electronic package due to thermal cycling stress is reduced by using an insert in a lid of an electronic device package wherein the insert has a coefficient of thermal expansion that is between about that of the lid and about that of a semiconductor substrate.Type: GrantFiled: May 20, 2002Date of Patent: November 25, 2003Assignee: Fry's Metals, Inc.Inventors: Attiganal N.
