Patent number: 5780164Abstract: A hard drive disk substrate is formed of a multi-phase ceramic-based material having at least two phases with amorphous phases being present in an amount less than about 1 volume percent based on the volume of the ceramic-based material or at least one phase being free metal. A process for producing the ceramic-based disk substrate is produced by forming a flat disk of a porous ceramic and then infiltrating the porous ceramic with a metal whereby a multi-phase ceramic-based computer hard drive disk is produced. Additionally, a step of passivating the porous ceramic by elevating it to a temperature of about 1300.degree. to about 1800.degree. C. before the infiltrating step may be performed, such that the surfaces are passivated and the reaction kinetics can be controlled during the infiltrating step. A preferred composite material is made of a multi-phase boron carbide composite material including grains having peaks with an average roughness value, Ra, of between about 1 to about 200 .ANG.Type: GrantFiled: June 29, 1995Date of Patent: July 14, 1998Assignee: The Dow Chemical CompanyInventors: Aleksander J.

Patent number: 5778545Abstract: A means for damping a low-friction azimuth resolver by use of an array of small magnets acting on a metallic pendulum attached to the resolver shaft. The magnetic field acts on the pendulum motion to induce a motional electromotive force and associated currents, which produce forces opposed to the motion, thereby acting as a non-contact damper on the resolver shaft. When the resolver shaft is at rest, no "eddy currents" are produced in the static magnetic field and no damping force exists. If the shaft moves, the attached pendulum cuts the magnetic flux lines and produces a drag force proportional to the shaft angular speed. The pendulum is typically made of diamagnetic material, such as lead or copper, thereby assuring that the induced forces arise solely from the motion. The magnetic field is produced by an array of small, but intense, samarium-cobalt magnets contained in a compact package providing for uniform damping throughout 360.degree. of resolver motion.Type: GrantFiled: May 6, 1996Date of Patent: July 14, 1998Assignee: General Electric CompanyInventors: Michael G. Smith, James Howard Terhune, Roy C. May, George A. Romano, Balasubramanian S. Kowdley

Patent number: 5781110Abstract: An RF EAS tag includes a substrate with a conductive element positioned on a face surface thereof and having electrically inductive properties. A capacitive element is positioned on the face surface and has electrically capacitive properties wherein the inductive and capacitive elements are operably coupled together to form a resonant circuit which resonates when an electrical signal of a predetermined resonant frequency is applied to the tag. The capacitive element comprises a dielectric ink substance having a high dielectric constant for producing the desired resonant circuit on a single face surface of the substrate. An alternative tag comprises a substrate with a conductive layer positioned thereon and a gap formed in the conductive layer exposing a portion of the substrate. This forms a slotline waveguide shorted at both ends. A high dielectric constant ink substance is then deposited in the slot.Type: GrantFiled: May 1, 1996Date of Patent: July 14, 1998Assignee: James River Paper Company, Inc.Inventors: Charles C.

Patent number: 5781776Abstract: A method of editing a real-time control program as it controls equipment is provided in which the editing occurs in a second area of memory and integrated into the pre-existing program by means of conditional jump instructions concatenated to that edited material. The pre-existing program is uninterrupted by the editing process except for a change of single instructions which do not affect the results of the execution but redirect the execution thread of that control program to be conditionally connected to the edited material. This single writing of single instructions, which do not affect execution results, precludes the possibility of the controller executing partially edited programs. The jump instructions are conditional on a test edit pointer to allow instantaneous implementation of the edits and a simple return to unedited instructions simply by changing the state of the flag.Type: GrantFiled: November 1, 1995Date of Patent: July 14, 1998Assignee: Allen Bradley Company, Inc.Inventors: David A.
