Abstract: A  process  for  depositing  an  adherent polycrystalline  diamond  thin  film  on  a  substrate, particularly a silicon or glass material, by chemical vapor  deposition  (CVD)  at  1  to  15  torr  and  low temperatures of the substrate of between about 350 to 600°C using hydrogen and methane and optionally carbon dioxide.  The substrate has diamond particles deposited on it or is polished with diamond particles prior to CVD.   The process produces films which are clear and adherent.  The films are particularly useful on silicon wafers with integrated circuits.

Title: Method and apparatus for sampling and analysis of furnace off-gases
Inventor: EVENSON EUAN J
IPC: G01N1/24
Filed: 1997-02-05
Granted: 2001-08-07
Abstract: A furnace system includes a furnace and a furnace monitoring and control system having a gas analyzer for analyzing the composition of furnace off-gases, and a sampling tube or probe used to obtain a high temperature off-gas sample for delivery to the gas analyzer. Gas samples are drawn to the gas analyzer, via the probe, by a vacuum. The probe is formed as a generally cylindrical or polygonally shaped hollow tube, which when mounted in the system defines a generally vertically extending elongated gas passage along which sample gas is drawn, and whereby sample gas flow in the passage is in a generally vertical direction. The probe is provided with upper and lower openings which extend into the gas passage. The lower opening is provided in gaseous communication with the furnace off-gas stream and is formed so as to permit the substantially unhindered movement of particulate matter, such as dust, downwardly along the gas passage and outwardly through theopen bottom end. The upper opening is provided in gaseous communication with thegas analyzer, and a filter is removably positioned across the upper opening to prevent dust and other particulate matter entrained in the sample off-gas from moving through the upper opening and into the gas analyzer. To cool the sample gas and prolong the filter life, part of the probe is provided with a double sidewall construction so as to define a partitioned annular chamber extending about at least part of the gas passage along which cooling fluid may move.

Abstract: A travel plan preparing device used for preparing a travel plan by accessing a data base from a terminal and acquiring information about service facilities existing on the route from the starting place to the destination. An area or desired kind of service is inputted through an input device (110) and transmitted to the database (100) through a transmitter-receiver (116). When an area is inputted, the data base (100) retrieves the information about the service facilities in the designated area and transmits the information to the terminal. When a desired kind of service is inputted, the data base (100) transmits the information about the positions of the pertinent service facilities and the electronic controller (ECU)(114) of the terminal calculates the distribution of the service facilities on a map, selects the area which best satisfies the inputted condition, and displays the area on a display device (12). A GPS navigation system (112) searches the route to the selected area and prepares a travel plan.

Abstract: An AGC circuit for a digital receiver that receives a digital television signal or the like, including a pilot, and formatted in a plurality of repetitive data segments, each data segment comprising a fixed number of multilevel symbols occurring at a constant symbol rate. The multilevel symbo ls are converted to corresponding digital values and the pilot (represented by a DC offset) is removed from the digital values. Every fourth symbol is sample d and the samples are accumulated and divided to derive an average symbol valu e. The average symbol value is compared with a reference average symbol value a nd the result of the comparison is an AGC potential that controls the tuner and  IF gains. A cable/terrestrial input alters the sampling for cable signals to  compensate for high level sweep testing in cable systems.

Abstract: An active edger includes an actively positionable gangsaw or a first end saw either mounted on an arbor mounted within a stationary saw box, wherein the gangsaw or first end saw is actively positionable relative to the saw box, or mounted on an arbor in fixed translational and skewing relation relative to, and within, an actively positionable saw box. In the latter embodiment the actively positionable gangsaw is selectively actively laterally translatable and selectively actively rotatable so as to skew the gangsaw relative to the saw box. In both embodiments, the saw box receives a workpiece, longitudinally conveyed in a downstream direction, longitudinally into the gangsaw or first end saw from an upstream position. A first chipping head, mounted to a first side of the saw box adjacent and downstream of the first end saw or a first end saw in the gangsaw is, in the first embodiment, selectively actively laterally positionable so as to align with a first feed line corresponding to the first end saw in unison with active positioning of the gangsaw, relative to the workpiece. In both embodiments, the first chipping head actively corresponds, in a lateral chipping depth, to a lateral edging dimension of a sawn edging sawn from the workpiece. The sawn edging is chipped as the workpiece is conveyed from, once sawn by, the gangsaw, longitudinally past the first chipping head.

Granted: 2002-05-21
Abstract: A method and apparatus generates grid cell property information that isadapted for use by a computer simulation apparatus which simulates properties of an earth formation located near one or more wellbores. An interpretation workstation includes at least two software programs stored therein: a first program called "Petragrid" and a second simulation program which is responsive to output data produced from the first "Petragrid" program for generating a set of simulation results. The set of simulation results are displayed on a workstation display monitor of the workstation. The first Petragrid software program will: receive well log and seismic data which indicates the location of each layer of a formation near a wellbore, and then grid each layer of the formation, the grid being comprised of a plurality of cells. The first Petragrid software will then generate more accurate data associated with each cell, such as the transmissibility of well fluid through each cell. The more accurate data for each cell originating from the first Petragrid software will be transmitted to the second simulation program. The second simulation program will respond to the more accurate data for each cell of the grid from the Petragrid software by generating a set of more accurate simulation results for each cell of the grid. The second simulation program will overlay the more accurate simulation result for each cell onto each of the corresponding cells of the grid which is being generated and displayed on the workstation display by the Petragrid software. As a result, the workstation will display each layer of the earth formation where each layer is gridded with a plurality of cells, and each cell has its own particular color which corresponds in numerical value to the particular more accurate simulation result (e.g., pressure or saturation) that corresponds to that cell.
