Abstract: A rotation mechanism includes a bearing mechanism and a drive mechanism. Prior to loading of a sample unit, bearing gas is supplied to a bearing mechanism. In the course of inserting the sample unit, bearing gas is sprayed to a surface of the sample tube from around the sample tube to thereby center the sample unit.

Abstract: A probe head in a nuclear magnetic resonance measurement apparatus includes a rotating mechanism. In the probe head, an exhaust gas having a high temperature or a low temperature is discharged from a discharge port of the rotating mechanism. An additive gas having room temperature is introduced into the probe head through a plurality of ejection holes. The additive gas is mixed with the exhaust gas, and, as a result, an exhaust gas mixture having a temperature closer to room temperature than is the temperature of the sample is produced. A deflector regulates the direction in which the exhaust gas flows.

Abstract: A direction shifting mechanism for changing a direction of a sample tube is installed on a path of the sample tube between a sample tube supporting unit for supporting, during an NMR measurement, the sample tube used for the NMR measurement and an insertion port through which the sample tube is inserted in and extracted from the sample tube supporting unit. The direction shifting mechanism has a shape which partially includes a form of an arc, and the shape is designed to cause the sample tube to change its direction in such a manner that the sample tube is turned toward the insertion port along the arc while being maintained in contact with at least two points on an inner wall of the direction shifting mechanism.

Abstract: A sample tube carrier includes a housing space in which a sample tube can be accommodated, and a locking mechanism constituted by a valve and a spring. When introducing a sample tube, the sample tube carrier is mounted on one end of a sample tube passage member communicating with an NMR probe device and the one end comes into contact with the valve and brings the valve into an opened state, thereby introducing the sample tube into the NMR probe device through the sample tube passage member. When collecting the sample tube, gas is jetted into the sample tube passage member toward the housing space and the gas pressure acts to discharge the sample tube from the NMR probe device to the housing space through the sample tube passage member.

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.
