Patent CA-2039062-C (CA)
Title: Network planning tool
Inventor: BLAKE BRUCE M
IPC: H04Q3/00
Filed: 1991-03-26
Granted: 1996-01-16
Abstract: A computer is provided with a network planning facility, which displays in map form a network comprising a plurality of nodes each serving a plurality of subtending nodes, and in which the network is characterized by data stored in the computer. The operation of the planning facility is initiated in response to a user entering an appropriate command.  Specifically, responsive to the command, the computer displays a plurality of symbols representing respective ones of the nodes, in which each such symbol is arranged so that it is indicative of the number of traffic terminations at it's associated node. The user may then select, in a conventional manner, one of the displayed symbols and then invoke either an automatic mode or a manual mode. In the automatic mode, the computer itself develops a plan for rehoming to another network node individual ones of the subtending nodes associated with the selected node, in which the rehomed subtending nodes are selected based on their having a predetermined traffic relationship with the other node. In the manual mode, it is the user, rather than the computer, which develops the rehoming plan.

Title: Lng cryogenic power generation system using molten carbonate fuel cells
Inventor: NAKAZAWA KENZO
IPC: H01M8/06
Filed: 1991-05-23
Granted: 1994-05-24
Abstract: ABSTRACT OF THE DISCLOSURE     An LNG cryogenic   power generation system using a molten carbonate fuel cell is equipped with   a COz separator.          The CO2 separator takes advantages of cryogenic LNG in a manner such that CO2 among gases discharged from an anode chamber of the fuel cell is liquefied with cryogenic LNG and separated from the anode exhaust gas.    Cell reactions take place at a cathode chamber and the anode chamber of the fuel cell to cause power generation  as the oxidizing gas which contains CO2 is fed to the cathode chamber and the fuel gas is fed to the anode chamber.          LNG is reformed by a reformer of the fuel cell and the reformed gas is fed to the anode chamber.   During the cell reaction, CO2 of the oxidizing gas fed to the cathode chamber is transferred as carbonate ion to the anode chamber and CO2 is enriched or concen-trated before expelled from the anode chamber.    This anode gas is introduced to the CO2 separator.   In the CO2 separator,  CO2 among the anode gas is liquefied by cryogenic LNG and separated from the anode gas.   As a result, the power generation and the CO2 recovery are carried out at the same time, and an amount of CO2 discharged to atmosphere is remarkably reduced.

Title: Video recorder with distortion corrector circuit
Inventor: REIME GERD
IPC: H04N5/931
Filed: 1991-10-08
Granted: 2000-08-08
Abstract: A distortion corrector circuit (11) arranged in the signal path (1) of the frequency-modulated brightness signal of a video recorder between the video tape (2) and the frequency demodulator (3) acts as a band-pass filter whenever the brightness signals fall below a certain threshold level (U16) and switches to act as an amplitude-controlled transmission time retarder whenever the brightness signals exceed the said threshold level. The phase errors produced during recording and transmission are substantially compensated in the latter mode, while in the former state oscillation sequences with atrophied oscillations have their amplitude resuscitated by the resonance effect. The threshold level (U16) is set by means of a disturbed signal recognition circuit (21) that detects the number and rate of the oscillations that do not exceed a certain recognition threshold of the disturbed signal recognition circuit that lies close to the switching point line of the frequency demodulator. In this way the distortion corrector circuit is adapted to the different reproduction qualities of different video tapes in such a manner as to obtain image reproduction with the least possible disturbance and the greatest possible definition.

Inventor: HATANAKA KATSUNORI
IPC: G01Q30/04
Filed: 1992-04-21
Granted: 1999-01-26
Abstract: In order to effect the reading-out of a signal from a recording medium at a high speed and without the collision of a probe electrode, the control of the spacing between the probe electrode and the signal recording layer of the recording medium is effected by sampling a tunnel current detected by the probe electrode at the timing of a reproduction clock, and reproduction is effected with this sampled value as a reference.       Also, in order to effect information recording with good reproducibility and at high density, the control variable of a servo control circuit for controlling the spacing between the probe electrode and the recording layer is changed over during the periods before and after a writing pulse is applied to the probe electrode.       Also, in order to effect re-recording reliably, the prior recorded state at the re-writing position is detected, and from the result of this detection, an optimal servo control variable, the waveform of a pulse voltage applied, etc. are set.

Abstract: The present invention involves assay methods and devices for performing binding assays, wherein the detectable label is a magnetically responsive material. Direct and indirect, competitive and sandwich assay formats are used to partition the magneti-cally attractable label between a solid phase and a fluid phase in proportion to the presence or amount of analyte in the test sam-ple. The magnetic responsiveness of the magnetically attractable label in one or both phases results in the exertion of a force upon the label. By determining the extent of the force or influence of the force exerted upon the label, the amount of the analyze in the test sample is determined.
