Abstract: An angle adjustment mechanism has a block, a projecting piece, and a connection mechanism. The projecting piece is fixed to a stator. The connection mechanism has elongated holes provided in the block and a shaft member provided in the projecting piece. The shaft member is inserted in the elongated holes. During a tilt angle adjustment process, the shaft member is caused to move in a sliding motion in the elongated holes. During a cooling process, the shaft member is also caused to move in a sliding motion in the elongated holes.

Abstract: A sample pipe is provided in a sample temperature control pipe. A detection coil is provided in a low-temperature airtight chamber and configured to irradiate a sample with a high-frequency magnetic field. A room-temperature shield is provided on an outer circumferential surface of the sample temperature control pipe or on an inner circumferential surface thereof, and is configured to block irradiation of the high-frequency magnetic field from the detection coil from reaching a region other than an observation object. A low-temperature shield is provided in an airtight chamber and between the detection coil and the room-temperature shield and is configured to block irradiation of the high-frequency magnetic field from the detection coil from reaching the room-temperature shield.

Abstract: A pair of detection coils, one coil provided on each side of a sample container across the width of the sample container. The detection coil is made of a superconductor and has an electric circuit pattern capable of detecting a magnetic resonance signal from a sample. The detection coil includes a lateral component intersectional to a static magnetic field H0 and having a part disposed at a position spaced away from a detection region, as compared to the remaining part.

Abstract: A device for attaching and detaching a cryogenic probe to and from a nuclear magnetic resonance (NMR) spectrometer. The device permits the probe to be loaded in the spectrometer in a shortened time and achieves high measurement throughput. The device has loading platforms (11-1, 11-2) on which cryogenic probes (P1, P2) are loaded. Each loading platform has a horizontal drive mechanism, a vertical drive mechanism, and a spacing mechanism. The device further includes probe cooling devices (14-1, 14-2) for circulating a refrigerant to and from the cryogenic probes (P1, P2) via transfer tubes (12-1, 12-2) made of a flexible material, thus cooling the probes (P1, P2). A temperature-controlled gas feeder (18) supplies a temperature variable gas for temperature adjustment to the probes (P1, P2). A vacuum pumping system (15) evacuates the interiors of the probes (P1, P2) via vacuum pipes (17-1, 17-2) made of a flexible material.
