Patent number: 6982240Abstract: A superconducting device operable at temperatures in excess of 30° K. and a method for making the device are described. A representative device is an essentially coplanar SQUID device formed in a single layer of high Tc superconducting material, the SQUID device being operable at temperatures in excess of 60° K. High energy beams, for example ion beams, are used to convert selected portions of the high Tc superconductor to nonsuperconductive properties so that the material now has both superconductive regions and nonsuperconductive regions. In this manner a superconducting loop having superconducting weak links can be formed to comprise the SQUID device.Type: GrantFiled: May 9, 1991Date of Patent: January 3, 2006Assignee: International Business Machines CorporationInventors: Gregory John Clark, Richard Joseph Gambino, Roger Hilsen Koch, Robert Benjamin Laibowitz, Allan David Marwick, Corwin Paul Umbach

Patent number: 6774463Abstract: In a Field Effect Transistor (FET) with a semiconductor channel the use of a high Tc oxide superconductor material in the gate electrode provides both control of parasitic resistance and capacitance and a proper work function when operated at a temperature below the Tc. The 1-2-3 compound oxide superconductors with the general formula Y1Ba2Cu3O7-y where y is approximately 0.1 have the ability in use in FET's to provide convenient work functions, low resistance and capacitance, and to withstand temperatures encountered in processing as the FET is being manufactured.Type: GrantFiled: February 24, 1992Date of Patent: August 10, 2004Assignee: International Business Machines CorporationInventors: Praveen Chaudhari, Richard Joseph Gambino, Eti Ganin, Roger Hilsen Koch, Lia Krusin-Elbaum, Robert Benjamin Laibowitz, George Anthony Sai-Halasz, Yuan-Chen Sun, Matthew Robert Wordeman

Patent number: 6052610Abstract: A method, apparatus, and system for tracking an object within a volume, includes coupling a rotating magnetic dipole to the object, measuring the magnetic fields either remotely, on the surface of, or exterior to the volume, to produce measurements; and based on the measurements, determining the position and the orientation of the magnetic dipole, thereby to determine a position and orientation of the object.Type: GrantFiled: January 9, 1998Date of Patent: April 18, 2000Assignee: International Business Machines CorporationInventor: Roger Hilsen Koch

Patent number: 6005800Abstract: A nonvolatile magnetic memory array uses magnetic memory cells that are formed in two types of shapes. The cells lie at the intersections of rows and columns of electrically conductive lines, which serve as the conductive paths for the write currents used to change the magnetization states of the magnetic cells. The two types of cells have shapes that are mirror images of each other, i.e, the shape of the second type of cell is arrived at by rotating the first type of cell 180 degrees about an axis through the cell. The two types of cells are thus a pair of asymmetric cells because they are asymmetric in regard to the predominant axis of magnetization. In the preferred pattern, each of the cells has a parallelogram shape with a length and a width with the predominant axis of magnetization lying substantially along a line between the acute corners of the parallelogram.Type: GrantFiled: November 23, 1998Date of Patent: December 21, 1999Assignee: International Business Machines CorporationInventors: Roger Hilsen Koch, Roy Edwin Scheuerlein

Patent number: 5642045Abstract: An improved magnetic field gradiometer having major and minor correction circuits is disclosed. The major correction circuits cancel the main components of an applied magnetic field, such as the earth's uniform field, and the minor correction circuits correct for smaller, but still significant effects, such as assembly imperfections and unavoidable cross-talk between the elements of the gradiometer. Also disclosed is a method for processing the gradient data from the gradiometer to enable the positions of magnetic objects to be located in space.Type: GrantFiled: August 18, 1995Date of Patent: June 24, 1997Assignee: International Business Machines CorporationInventors: George Andrew Keefe, Roger Hilsen Koch
