Publication number: 20240136180Abstract: A method for growing nanocrystalline diamond (NCD) on Ga2O3 to provide thermal management in Ga2O3-based devices. A protective SiNx interlayer is deposited on the Ga2O3 before growth of the NCD layer to protect the Ga2O3 from damage caused during growth of the NCD layer. The presence of the NCD provides thermal management and enables improved performance of the Ga2O3-based device.Type: ApplicationFiled: October 19, 2023Publication date: April 25, 2024Applicant: The Government of the United States of America, as represented by the Secretary of the NavyInventors: Marko J.

Patent number: 8146388Abstract: An apparatus for drawing a glass ribbon including a shroud surrounding the glass ribbon and an edge roll that penetrates the shroud to contact the glass ribbon. The apparatus includes regulating a pressure within the seal assembly to be equal to or less than a pressure within the shroud and prevent ingress of relatively cooler outside gas into the hot interior of the shroud. The edge roll utilizes an air bearing to minimize friction that can produce periodic fluctuation of the ribbon as the edge roll is displaces in response to variations in the ribbon thickness or equipment dimensions.Type: GrantFiled: October 29, 2009Date of Patent: April 3, 2012Assignee: Corning IncorporatedInventors: James G.

Patent number: 5703278Abstract: A conventional fluid density balance beam measurement instrument used for measuring fluid density at atmospheric pressure is converted for use to measure fluid density at super-atmospheric pressure. The conversion is made without modifying the structure of the conventional instrument. A pressure lid, placed over the open mouth of the instrument's sample cup, is held in place by a removable retaining structure that wraps around the base of the cup. A screw ring at the top of the retainer applies a retaining pressure against the lid. Pressure is applied to the cup through a check valve stem extending through the lid. An adjustable flange on the rim of the lid permits the lid to advance into the cup to change the cup volume for sizing the cup to obtain a precisely known volume for measurement. A counterweight is removably connected to the balance beam to compensate for the weight added by the lid and retaining structure.Type: GrantFiled: May 3, 1996Date of Patent: December 30, 1997Assignee: Fann Instrument CompanyInventors: Robert J. Murphy, Jr., James G. Anderson
