Title: Measuring method and device for insulation of cable in live line state
Inventor: NAKAYAMA TADAHARU
IPC: G01R27/18
Filed: 1989-02-22
Abstract: PURPOSE:To accurately measure the insulation resistance of a cable operating in a live line state in an appropriate measuring time without error by successively measuring a time changing factor of the charge voltage for DC signal voltage and monitoring the changing factor until it is lowered than a limit value. CONSTITUTION:A switch 18 is opened/closed and changing-over switches 7, 23 are changed-over by an OPU 27, wherein signals for the measured voltage sent every moment from a digital voltmeter 24 are received to successively measure the time changing factors of the charge voltage for the impressed DC signal voltage. The changing factors are monitored until the time when the time changing factors are lowered than the limit value which is decided in advance by the product of an electrostatic capacitance value of the cable to be measured and a maximum resistance value desirable to measure. Next, after a lapse of specified time from the time when the time changing factor is reached to the limit value, the voltage which is generated from a leak current flowing through a resistor for measurement connected between a shield for the cable to be measured and a grounding point, is measured. Therefor, the insulation resistance for the cable operating in the live line state can be automatically measured in the appropriate time without error.

Title: Equipment and method for magnetic resonance pursuit
Inventor: SUTEIIBUN PIITAA SAUZA
IPC: A61B5/055
Filed: 1994-03-15
Abstract: PURPOSE: To provide a tracking apparatus which monitors a position of a device such as a catheter in the human body to be inspected, using magnetic resonance signals. CONSTITUTION: In the device 150 in the human body to be inspected, a receiving coil 200 is set up which is sensitive to magnetic resonance signals, and the tracking apparatus detects these signals under the existence of a magnetic field gradient. By detecting the signals having a frequency proportional to a position of the coil along the applied gradient direction, the position of the device in the human body to be inspected is determined.  In order to minimize the effect of an offsetting state of the resonance on measured positions, such as an unsatisfactory adjustment of the frequency of a transmitter, a chemical shift and so, the position of the device in orthogonalized three dimensions is determined through selecting an amplitude and a polarity of the magnetic field gradient, repeating measurements several times, and calculating a linear combination of data collected corresponding the different magnetic field gradient.
