摘要： PROBLEM TO BE SOLVED: To provide a biomagnetism measuring apparatus capable of easily detecting brain magnetic field with higher sensitivity than usual, more practically, easily closing the sensor surface to the head surface of a test subject by coupling two independent cryostats while keeping the enantiomeric composition, and detecting the brain magnetic field of right and left brains with high sensitivity at the same time. SOLUTION: This biomagnetism measuring apparatus has two independent cryostats which hold a SQUID fluxmeter and are mounted to be in enantiomeric composition. These two cryostats move together from right to left or up and down and rotate during the enantiomeric composition. The gantry holding cryostats is a portal type with the consideration to suppress the vibration of cryostats. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an immunological examination technique capable of efficiently examinating antigen-antibody reaction magnetically with high sensitivity using magnetic fine particles and a SQUID magnetic sensor.
SOLUTION: The immunological examination apparatus has: a disk-shaped sample holder 3 for circumferentially holding a prurality of sample containers 2, each of which houses a labelled specimen prepared by labelling a specimen with magnetic fine particles; a rotary means 4 for rotating the holder 3 around its axis; and a magnetic censor 11 for detecting the magnetic field generated from the magnetized labelled specimen in a magnetic shield. The region for holding a different sample container is inserted in the magnetic shield successively by the rotation of the holder 3 and the magnetization of the labelled specimen in the first sample container and the detection of the magnetic field generated from the labelled specimen housed in the second sample container are performed parallelly.

摘要： PROBLEM TO BE SOLVED: To provide a magnetic field measuring apparatus capable of simultaneously and stably operating a plurality of SQUID flux meters. SOLUTION: In the magnetic field measuring apparatus provided with the plurality of SQUID flux meters 12 with detection coils, an oscillation frequency to perform AC bias is decided by a single oscillator 13 in common to all CHs. Switches SW0, SW1, SW2, SW3, SW4 and SW5 are switched with signals from the oscillator as a reference, and application of AC bias signals, cancellation voltage signals and offset magnetic flux signals is selected. On the basis of a method of using a cross correlation function by using V-Φ characteristics at the time of a bias voltage on a positive side and V-Φ characteristics at the time of current bias on a negative side or a method of spectrum-analyzing the V-Φ characteristics for which the AC bias is performed, the AC bias signals are automatically adjusted.

摘要： PROBLEM TO BE SOLVED: To provide a magnetic shield device capable of shielding external magnetic fields in the axial direction of a magnetic shield tubular body and in the perpendicular direction to the axial direction. SOLUTION: The magnetic shield device comprises a cylindrical ferromagnetic body 2-1 having openings at both ends, and two superconductive closed loops stored inside respective superconductive closed loop vessels 1-1 and 1-2. The superconductive closed loops are formed of high-temperature superconductive wires. Two superconductive closed loops are semicircular, and are arranged in the x direction symmetrically with respect to the center axis of the cylindrical ferromagnetic body 2-1. The superconductive closed loop vessels 1-1 and 1-2 are arranged inside near both opening ends of the cylindrical ferromagnetic body 2-1 via a support tool 20. The superconductive closed loops are arranged vertically to the center axis of the cylindrical ferromagnetic body 2-1. Additionally, the superconductive closed loops are cooled by liquid nitrogen or a refrigerator. Thus, a light and small magnetic shield with high opening property can be realized.
