Abstract: An as-fired alumina substrate for a hybrid micro-circuit formed of GaAs dies operating at gigahertz frequencies has a large number of about .013" diameter via holes drilled on the surface thereof by use of a laser.  A metal filling in each via hole is formed with about 85% sintered tungsten and 15% copper reflowed into the pores thereof to provide a composition that has a thermal coefficient of expansion that substantially matches that of the GaAs dies and the alumina substrate and also provides for hermetically sealing the via holes. The alumina substrate is further provided with a ground plane by which it is mounted on a metal block serving as a heat sink.  The high frequency GaAs dies mounted on the via holes use the metal fillings therein to carry their internally generated heat to the heat sink and to provide low inductance ground paths for the microcircuit.         A process for placing the metal filling in the via holes makes use of a stencil having the same large number of via holes thereon as the alumina substrate for first squeegeeing a tungsten paste with a predetermined amount of binder into the via holes of the substrate.  After the tungsten is sintered, the stencil is then used to squeegee a copper paste on the top of the sintered tungsten in the via holes.  The copper in the paste is then reflowed into the pores of the sintered tungsten.

Granted: 1995-05-30
Abstract: When there are variations in the short-circuit power of a system, the operating conditions can change, particularly in a controller of a compensating device.  To automatically adapt the controller and to avoid or suppress oscillations or voltage variations in the system, a method is provided according to a first solution, where the circuit state of a compensating element is modified for testing purposes.  The reaction of the system is detected in a device and, then a parameter which determines the damping of the controller is modified by means of a computing device.  According to a second solution, an oscillation of the controller is established by detecting a signal which is dependent on the system voltage and by comparing specific variations.  To suppress the oscillations, the hysteresis of the controller is damped by means of the computing device.

Title: Statistically based continuous autocalibration method and apparatus
Inventor: HILTON HOWARD E
IPC: G12B13/00
Filed: 1990-11-14
Granted: 2000-11-07
Abstract: Errors in a sampled data process are discerned statistically throughout the process, permitting their efficient removal. An exemplary application is a subranging analog-to-digital converter (ADC) (10), in which errors associated with component digital-to-analog (DAC) current sources (28, 30, 32) are discerned and corrected automatically during the circuit's normal operation. This is achieved by continually introducing a random signal into the process, statistically examining the DAC  output signal to discern error terms, and correlating the occurrences of these errors with the values of the random signal applied to the DACs so as to identify the current sources to which the error terms are due. The resulting ADC output signal is compensated to remove the random signal and is further compensated to remove the DAC error terms discerned by this statistical analysis, The effect of any errors that may remain due to imperfect quantification of the DAC error terms is minimized due to their randomization, permitting the removal of these error terms by averaging techniques.

Title: Single horizontal wellbore process/apparatus for the in-situ extraction of viscous oil by gravity action using steam plus solvent vapor
Inventor: SANCHEZ JAMES MICHAEL
IPC: E21B43/24
Filed: 1992-01-07
Granted: 2002-05-21
Abstract: A conduction heating, gravity assisted, single well, process for removing viscous hydrocarbonaceous fluids from a reservoir penetrated by a horizontal wellbore. Steam and a gas soluble in hydrocarbon-aceous fluids are circulated into the wellbore at or below the reservoir pressure through an upper perforated conduit of the horizontal wellbore.      Circulation is continued so as to allow steam to heat the reservoir by conductance while gas enters the hydrocarbonaceous fluids. Thus, heated hydrocarbon-aceous fluids having a reduced viscosity flow from the reservoir around the horizontal wellbore where the fluids are produced to the surface by a lower conduit within the horizontal wellbore. The lower conduit is open along its length so as to be in fluid communi-cation with the reservoir for the length of the horizontal wellbore.

Filed: 1992-04-06
Granted: 1994-05-17
Abstract: A bag closing machine has a pair of endless belts mounted in a housing and having adjacent runs extending along a passage in the housing.  The belts are driven to cause bags to be conveyed successively between the runs along the passage.  A heating station adjacent the passage is operable to heat sealing areas of the bags to activate heat sealable material in a bag closing manner.  The heating station has at least one pair of nozzles, one nozzle of each pair being on one side of the passage and the other nozzle of each pair being on the opposite side of the passage, the nozzles being directed towards the sealing area of a bag passing the heating station.  Hot air is supplied to the nozzles to cause hot air to be emitted from the nozzles and impinge on the sealing area of a bag to activate the heat sealable material in a bag closing manner.  When no bag is passing the heating station, hot air from the nozzles is removed to a location remote from the drive belts.  The belts and associated parts may be mounted in respective separable portions of the machine to facilitate maintenance.
