Title: Impedance matching device for rf coil for mri device
Inventor: KOIKE MASANOBU
IPC: A61B5/055
Filed: 1989-10-16
Abstract: PURPOSE:To improve the matching precision by varying the circuit constant of an impedance matching circuit, detecting the difference between the output signal supplied from a lever measuring means and the output signal supplied from a peak hold means, detecting the time point when the difference exceeds a threshold value, and shifting the circuit constant by a prescribed value. CONSTITUTION:When the control output (v) of a voltage control circuit 67 is gradually increased from 0V to a certain voltage, the resonance frequency of an impedance matching circuit 12 varies. Through the variation, a through signal (a) gradually increases, and also the peak hold signal (b) gradually increases through the slight deflection. When the through signal (a) reaches the max. and then reduces gradually, reversal with the peak hold signal (b) occurs in the vicinity of the max. point of the through signal (a), and the level difference between the peak hold signal (b) and the through signal (a) gradually increases afterwards. The time point when the difference exceeds a threshold value V1 is detected by a comparison circuit 65. At this time point, the variation of the control voltage (v) of the voltage control circuit 67 is suspended. Further, the voltage control circuit 67 returns the control voltage (v1) in stop by the deflection portion, and sets the voltage at (v0). Accordingly, the capacity of the variable capacity element of the matching circuit 12 is fixed.

Abstract: PROBLEM TO BE SOLVED: To prevent an illegal program from being modified based on program analysis inside equipment. SOLUTION: When power is supplied from a main power source 6, a CPU 1 transfers a program in a flash memory 2 to a volatile memory 3, erases the program in the flash memory 2 and afterwards performs the prescribed processing according to the program in the volatile memory 3.

A fixed value or more from the background is set as a fitting range F. The function fitting calculation is then carried out to calculate the peak position and peak intensity from the determined functions of the spectral lines A, B of the respective elements. Thus, the spectral lines A, B can be automatically separated to determine the intensity value close to a true value.

Abstract: PROBLEM TO BE SOLVED: To improve the refrigerating efficiency by preventing the arrival of operating fluid of high temperature flowing from the high-temperature end side of a pulse tube to the interior of a pulse tube at a low-temperature end side and a cooler. SOLUTION: A moving member 6 made of a sphere formed substantially in the same size as the sectional area of a pulse tube 5 and moving together with operating fluid is inserted into the tube 5. A stopper member 7 for limiting the moving range of the member 6 is provided at the inner wall of the tube 5.

Simultaneously, the moving range of the member 6 can be specified in the predetermined range of the high-temperature end 15 side to reduce the temperature change of the member 6, and hence the reliability of the member 6 can be improved.
