Title: Method for measuring flow in nuclear magnetic resonance experiment
Inventor: PATORITSUKU RURUU
IPC: G01P13/00
Filed: 1988-05-12
Abstract: PURPOSE: To enhance a dynamic range effective for displaying a moving part through only one data sampling by selectively exciting at least one section of the body, inverting the direction of the magnetic moment of the part of the body located in the section, and processing its resonance signal. CONSTITUTION: Excitation involves first excitation 18 in which the direction of the magnetic moment of particles located in the region of the body to be examined is tipped 90' for the purpose of spin-echo excitation. This excitation further involves second inversion excitation 19 called spin echo. The directions and phases of the precessions of the magnetic moments of the particles excited in the region which becomes problematic because of the nonuniformity of an orientation magnetic field B0 are dispersed, but this dispersion is inverted by the inversion excitation. A selective gradient pulse 20 is applied at the same time as the inversion excitation 18. After the pulse 20 a phase re-coding pulse 21 continues. At the moment when the inversion pulse 19 is applied, a gradient pulse 22 along Z-axis is applied. Signal measurements are made using a gradient pulse 23.  The gradient pulse 23 is given a gradient in the direction of an axis for selecting a section.

A bias driving detecting member 28 is arranged at a shaft end of the third roller 5 so that when the sensitive belt 6 is driven bias and brought into contact with the bias driving detecting member 28, one of the shaft ends of the third roller 5 is displaced using rotation torque of the bias driving detecting member 28 to solve initial bias driving. Tension arms are extended between both shaft ends of the second roller 4 and the third roller 5, and an elliptic hole 18a extending toward the displacement direction of the shaft end is formed on one of the tension arms 18. Also, these tension arms 18 are provided with a bias driving detection belt 30 for converting the rotation torque to shaft-end displacement and a backtension spring 25 for applying an energizing force to the shaft end in the direction opposite to the displacement direction to make them a unit so as to improve assembling workability.

IPC: H04B7/26
Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To prevent transmission of information from being not received because of a radio wave dead zone with a simple and inexpensive configuration. SOLUTION: An electric field strength meter 6 receives an electric field strength to discriminate whether or not data are receptible. In the case that the data reception is disable (resident in a radio wave dead zone), the meter 6 allows a time recording section and an integration counter function of a CPU 3 to be active to integrate the time for disable data reception. Then the CPU 3 drives an LED 4 and a speaker 5 to inform it that a pager possessor is resident in a radio wave dead zone by means of light and sound. When the pager possessor is resident a radio wave dead zone, the possessor operates a key entry section 8 to inform the dead zone time to a pager base station in terms of a DTMF signal under the control of the CPU 3, receives re- transmission of data so as to prevent the information from being not received.

Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To extract a region with high accuracy by changing a threshold value used in outline extraction to again extract an outline if a difference between the time series data and the smoothed data exceeds a threshold value. SOLUTION: Image data is read from an image memory 21 and input to an extract means 22 to extract the outline of the left ventricle of the heart shown on a tomographic image of the heart which image data bears. The time series data is obtained from the data showing the extracted outline of the left ventricle by an arithmetic means 23, and the time series data is input to a smoothing means 24. The time series data is smoothed by the smoothing means 24 to obtain the smoothed data, and a determining means 25 determines whether a difference between the time series data and the smoothed data of each tomographic image exceeds a second threshold value or not.  The determination result is feedbacked to the extracting means 22, and in the extracting means 22, if it is determined by the determining means 25 that the difference exceeds the second threshold, a first threshold value used in outline extraction is changed to again extract the outline.
