A gas charge container includes a sample holder which holds a needle-shaped material, a deutrium gas supply portion which charges a deutrium gas into the needle-shaped material held by the sample holder, and a heating portion which heats the needle-shaped material held by the sample holder. The needle-shaped material is cooled by blocking the heat generated by the heating portion after the needle-shaped material is heated by the heating portion.

An ultrasonic probe to be used for an ultrasonic diagnostic apparatus for obtaining an ultrasonic image. The ultrasonic probe comprises a catheter having a hollow tubing structure, a joint having a tubing structure and arranged to be at its one end portion connected to a tip portion of said catheter, a bearing connected to the other end portion of the joint, a rotating shaft inserted into the bearing to be rotatable and arranged so that a portion of the rotating shaft contacts with one end portion of the bearing, and a rotator connected to the rotating shaft and arranged so that one end portion of the rotator contacts with the other end portion of the bearing so that the bearing is interposed and supported between the portion of the rotating shaft and the rotator. An ultrasonic transducer is inserted into the rotator for transmitting and receiving an ultrasonic wave, a torque transmission shaft having a hollow structure is at its one end portion connected to the rotating shaft, and a guide wire is inserted into the hollow of the torque transmission shaft. A rotating force generated by a drive section is applied through the torque transmission shaft to the ultrasonic transducer whereby the ultrasonic transducer rotationally driven to perform a radial scanning operation. This arrangement allows a free movement of the guidewire within the catheter so that the catheter can easily be lead along the guidewire up to a target portion within a blood vessel.
