Patent CA-2009178-C (CA)
IPC: G01T1/24
Filed: 1990-02-02
Granted: 1999-03-09
Abstract: A composite radiation detection and indicating device comprises first, third and fifth layers of a transparent conductive material, a second layer of semiconductive diamond between the first and third layers, and a fourth layer of liquid crystal material between the third and fifth layers.  The layers are sandwiched together so that a diodic structure having a radiation-dependent charge storage characteristic is defined by the first, second and third layers, and a liquid crystal display element is defined by the third, fourth and fifth layers.  The invention extends to a radiation detector including the composite  device,  together  with  an  oscillator  for applying a charge to the diodic structure, and a sensor for monitoring the decay of the stored charge.  A voltage is applied to the liquid crystal display element to cause it to change state when the charge stored by the diodic structure decays below a predetermined limit.

Title: Tunnel junction device composed of compound oxide superconductor material and method for fabricating the same
Inventor: YAZU SHUJI
IPC: H01L39/22
Filed: 1990-11-27
Granted: 1997-11-18
Abstract: A tunnel junction device includes a pair of superconduction layers formed of a compound oxide superconductor material and a non-superconduction layer formed between the pair of superconduction layers. The non-superconductive material layer is formed of a compound oxide superconductor material which is substantially the same as that of the first and second superconduction layers but which is doped with a dopant of an amount sufficient for the compound oxide superconductor material to lose the superconduction property. The first superconduction layer, the non-superconductive material layer and the second superconduction layer have a continuous crystal lattice as a whole.     The above mentioned tunnel junction structure is formed by continuously depositing the compound oxide superconductor material on a substrate without interrupt of deposition from a beginning of the deposition of the first superconduction layer until a termination of deposition of the second superconduction layers, and adding a dopant concurrently with deposition of the compound oxide superconductor material only at the time of forming the non-superconduction layer, so that the first superconduction layer, the non-superconduction layer and the second superconduction layer are continuously formed in the named order without interrupt of deposition of the compound oxide superconductor material.

Title: Signal processing apparatus and method
Inventor: GERT LYKKE MOELLER
IPC: G06N5/04
Filed: 1990-02-02
Granted: 2000-04-04
Abstract: An input signal SV has components representing aspects of a physical entity which are in a known state and other components which are unknown. The apparatus processes the signal in accordance with stored data representing rules which indicate which combinations of the components are possible. Rules are identified which involve the known components and all of the combinations consistent with the known states are identified. If all of these combnations have the same value for a particular component, the component is determined to have that value in the output signal. The rules are stored as binary representations of the possible combinations, and the components of the input and output signals may represent two allowable states, tautology (undefined state) and inconsistency (inallowable state).

Title: Method of manufacturing a circuit breaker
Inventor: REZAC WILLARD J
IPC: H01H71/02
Filed: 1990-06-27
Granted: 2000-05-09
Abstract: This invention relates to a method of manufacturing a circuit breaker. Known methods suffer from the drawbacks of difficult preassembly of the breaker mechanism because it is held together by the housing and also because it is difficult to automate the process because parts need to be assembled along three orthogonally related axes. The above problems are solved by peassembling the movable parts of the circuit breaker (10) between a pair of frame members (42, 89) supporting the unitary breaker assembly (40) without attachments. Other circuit breaker components, attached to the unitary breaker assembly, are also supported in the housing (11) without attachments. A cover (11b) is secured to the housing to complete the circuit breaker. Another version of the invention preassembles the movable parts of the circuit breaker (10') and the stationary contact mechanism (28) and trip coil (31) with the line and load terminals (12, 14) attached, between a pair of supporting frame members (105) to form an operable circuit breaker module (40). The module (40) is in turn supported in a housing (11) without attachments. The circuit breaker module (40) may be tested and adjusted prior to final assembly.

Title: Method and apparatus for producing a porosity log of a subsurface formation corrected for detector standoff
Inventor: ALLEN LINUS SCOTT
IPC: G01V5/10
Filed: 1992-03-19
Granted: 2002-11-12
Abstract: A borehole logging tool is lowered into a borehole traversing a subsurface formation and a neutron detector measures the die-away of nuclear radiation in the formation. A model of the die-away of nuclear radiation is produced using exponential terms varying as the sum of borehole, formation and thermal neutron background components. Exponentially weighted moments of both the die-away measurements and die-away model are determined and equated. The equated moments are solved for the ratio of the borehole to formation amplitude components of the measurements.      The formation decay constant is determined from at least the formation and thermal neutron background terms of the weighted measurement and model moments. The determined borehole to formation amplitude ratio is used to correct the determined formation decay constant for the effects of detector standoff from the borehole wall. A porosity log of the formation is produced which is corrected for detector standoff from the borehole wall as a function of the standoff corrected formation decay constant calibrated in borehole models of known porosities.

Title: High dynamic range modulation independent feed forward amplifier network
Inventor: TATTERSALL DEREK L JR
IPC: H03F3/20
Filed: 1993-01-27
Granted: 1996-04-30
Abstract: Briefly described the present invention is a feed forward amplifier network (200) employing a frequency swept pilot tone signal (212) in order to reduce the distortion generated by the network's power amplifier (202). Initially a composite input signal (216) comprising either wide (520) and/or narrow (510) bandwidth modulation formats is input into the network (200). In addi-tion, the frequency swept pilot tone (212), generated for example by a variable frequency oscillator (213), is injected into the input path of the power amplifier (202). Thereafter, distortion cancellation is employed to generate an amplified output signal (217) having output components (510, 520) which replicate those within the input signal (216). Thereafter, pilot tone power is detected (by 215) within the amplifier passband where the output components (510, 520) are absent, in order to ascertain the average pilot tone power remaining within the amplified output signal (217). In response to this detection, various amplifier network character-istics are adjusted (by 214, 208 and 209) in order to reduce the amount of pilot tone at the amplifier network output (217).
