Title: Converting circuit for input signal level
Inventor: YOSHIZAWA HIROSHI
IPC: H03K5/02
Filed: 1984-11-16
Abstract: PURPOSE:To drive an inverter circuit with a data signal of a low amplitude by combining two MISFETs and a capacitor. CONSTITUTION:Both FET 9 and 10 are turned on while a clock pulse of forward phase applied to a terminal 3 is kept at a high level. Then a capacitor 11 is charged with a data signal of a low amplitude of 0-1V. Then said clock pulse is changed to a low level and FET 9 and 10 are turned off. Thus the voltage level rises up at the drain side of the FET 10, and the electric charge charged to the capacitor 11 has no place to shunt. Therefore the data signal of 0-1V is changed to 1-2V for the input voltage of an inverter consisting of FET 12 and 13. As a result, an inverter consisting of FET 12 and 13 is driven. In such a way, an inverter circuit can be driven with a data signalof a low ampli tude.

Title: Magnetic resonance diagnostic apparatus
Inventor: KUROKAWA MASAAKI
IPC: A61B5/055
Filed: 1989-09-21
Abstract: PURPOSE:To obtain sensitivity distribution characteristics suitable for diagnosis by installing shield plates for shielding other parts than a specified part of subject's body so as to concentrate an excitation RF magnetic field formed by an RF signal to that specified part and also to increase a sensitivity of reception by using that shield plate. CONSTITUTION:RF flux 4 is increased only in the vicinity of edges of shield plates 6, because eddy currents due to the RF flux 4 flow to the edges of the shield plates 6. Transmission and reception sensitivities of an RF coil 1 are proportional to 1/sq. rt. r, wherein (r) is an equivalent series resistance of the RF coil 1. (r) is represented as a sum of current loss in the RF coil proper, eddy current loss in load, etc., but (r) in an NMR diagnosis is almost represented as the loss originated by the load when a high quality RF coil is used. (r) is made smaller by placing the shield plates 6, because the eddy current loss originated by the shield plate becomes smaller as compared with the loss originated by the human body, and the sensitivities of RF coil 1 are, therefore, increased. S/N ratio in the reception is improved and the transmission output is allowed to be reduced as the transmission and reception sensitivities can be thus increased.
