摘要:
An NMR probe permits measurements to be made with its inner coil without replacing the probe. The NMR probe has three coils disposed to surround a sample tube. An inner coil can resonate with the HF and LF. An intermediate coil can resonate with the HF and LF, and produces an RF magnetic field perpendicular to the RF field produced by the inner coil. An outermost coil can resonate at least at a lock frequency. The outermost coil produces an RF magnetic field which is perpendicular to the RF field produced by the intermediate coil but which is coincident in direction with the RF field produced by the inner coil.

An NMR probe is offered which enables a 1H/19F compatibility mode having a sample coil, a hollow tubular body, and two rod electrodes disposed inside the tubular body substantially in a parallel relationship to each other. The tubular body is formed by a conductive wall at ground potential. An RF input-output portion corresponding to the resonant frequency of 1H nucleus is connected with the one end of the coil via a tuning and matching device. Another RF input-output port corresponding to the resonant frequency of 19F nucleus is connected with an end of the coil via another tuning and matching device.

A diaphragm for a planar speaker and a planar speaker having a long-term stability and a high reliability and exhibiting a flat sound pressure frequency property. The diaphragm for a planar speaker includes a voice coil formed by winding a wire conductor, two adhesive layers sandwiching the voice coil therebetween, and bases bonded to the two adhesive layers on the side opposite to the voice coil. The planar speaker employs the diaphragm.
