    摘要： In an electron paramagnetic resonance spectrometer, a closed cycle cryocooler is used to cool gaseous helium, which is then circulated around a sample to cool the sample by direct convection. Since the sample is not mechanically connected to the refrigerator, no vibrations are transmitted from the refrigerator to the sample and the sample can be quickly removed and replaced. The cooled helium can be passed through a Joule-Thomson expansion device before circulating the cooled helium around the sample to further cool the helium. In addition, a vacuum pump can be connected to the helium outlet after circulating the cooled helium around the sample to increase the pressure differential across the Joule-Thomson expansion device and further cool the helium. In order to raise the temperature of the cooled helium, a heater can be placed about the cooled helium line upstream from the sample.

    摘要： The present invention discloses a magnetic currency verification head comprising a magneto resistive sensor chip (41), and a magnetic bias unit (45) disposed on the side of the magneto resistive sensor chip (41) away from the detection surface (40) of the magnetic currency verification head, and separated from the magnetoresistive sensor chip (41); the magnetoresistive sensor chip (41) comprises a bridge circuit wherein the bridge arms are magnetic sensor elements; the sensitive direction (49) of the magnetic sensor elements is parallel to the detection surface (40) of the magnetic currency verification head ; and the magnetic bias unit (45) has a recessed structure; the recessed structure is configured such that the magnetic field generated by the magnetic bias unit (45) only has a small magnetic field component in the direction parallel to the detection surface (40), thereby enabling the magnetic sensor elements to operate in their linear range. As a result, the magnetic currency verification head has high sensitivity and signal-to-noise ratio.

    摘要： A magnetic resonance imaging apparatus using a transverse magnet system (29) and having a patient handling arrangement (31, 33) which allows transport of a patient into the magnet system by first moving the patient in a direction (A) at right angles to the head-to-toe axis (B) of the patient. The patient's position in the magnet system may then be adjusted by movement in the head-to-toe axis direction. The area required to accommodate the apparatus is reduced compared with apparatus wherein patient transport is effected solely in the patient's head-to-toe axis direction.
