摘要： PROBLEM TO BE SOLVED: To provide a uniform field magnet proper for NMR, which has a port accessible from a direction other than a magnet axis to the field center. SOLUTION: A superconducting magnet device comprises a split type electromagnet 6 which the first superconducting coil block 4 and the second superconducting coil block 5 are arranged face to face with a gap and has an access port for making access from the gap to a measurement space in the field center. A region including a notch and defect made in the magnet-composing elements such as a coil former for placing the access port is constituted axisymmetrically by using a material with relative transmissivity of 1.000 to 1.002. By using the material with relative transmissivity of 1.000 to 1.002, an error magnetic field is reduced and a uniform field magnet can be provided. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a magnet differential pressure/pressure transmitter for an NMR analyzer capable of applying thereto a solenoid type detection coil in order to improve NMR measurement sensitivity.
SOLUTION: This magnet for the analyzer has a constitution wherein an access port from the magnet center shaft direction is provided in order to access a measuring space 3 of the magnet center, and a gap 12 is provided in a coil winding part, and an access port passing the part is installed so that a sample can be arranged vertically to the coil center shaft. The size of the access port passing the winding part is smaller compared with the access port passing the coil center shaft, and the sample is inserted from the access port, and a probe is inserted from the access port passing the center shaft, to thereby minimize the gap size.

摘要： PROBLEM TO BE SOLVED: To provide a superconducting coil system being capable of avoiding an excessive electromagnetic force by a coil quenching and a high temperature and a high voltage by an energy concentration and realizing a passive operation having a high reliability in a multilayer superconducting coil used for an MRI device, an NMR device or the like. SOLUTION: The shunt resistances of the protective circuit are used as resistance heaters, or the resistance heaters are installed in parallel with the shunt resistance, and the heaters are mounted on the adjacent coils to the coils contained in the protective circuit. The same protective circuit is constituted regarding paired coils at symmetrical positions. Accordingly, when a certain superconducting coil is quenched, a current flows through the resistance heaters combining the shunt resistances of the protective circuit, and each heater heats the adjacent superconducting coils. The protective circuit can be operated surely even when an active quenching is not detected for quenching these superconducting coils. COPYRIGHT: (C)2006,JPO&NCIPI
