<p>PURPOSE:To prevent mistake in setting and make operation easier by selecting a sentence for command of suitable conditions and inform them acoustically. CONSTITUTION:A specimen 4 is placed in the gap of a magnet 3, and a continuous wave that is given from a frequency source 1 is pulse-modulated by a modulator 2 and amplified, and then directed to a specimen through a coil 5. When atomic nucleus resonance occurs, an electromotive force develops in the coil 5, and this signal is amplified and rectified by a rectifier 7, using a reference signal from the frequency source 1 and changed into an autio signal. Response signal of the atomic nucleus is obtained by a band amplifier 8, and it is digitized and stored in a CPU11 or a memory 16. In the voice generating circuit 14, a micro computer 18 issues a start instruction to a voice synthesizing LSI17, and the LSI17 reads instruction sentence specified by an address selected by voice memory ROM19 and sends it to the LSI17. The output of the LSI17 becomes voice by means of a speaker 15.</p> |
