Abstract: A magnetic field intruding into an electron lens area from outside an X-ray image tube is detected by a magnetic field sensor. A magnetic field for offsetting the magnetic field is generated by a coil arranged in an input surface area of the X-ray image tube, so that the distortion is corrected by removing the effects of the magnetic field. The magnetic field sensor is arranged in an area surrounded by a magnetic shield of the X-ray image tube and constituting an outer peripheral area on the electron lens area side distant from the input surface area of the X-ray image tube. The magnetic field sensor is such that the effects of the magnetic field generated by the coil are reduced and the magnetic field intruding into the electron lens area is accurately detected.

Abstract: An input speech signal is compressed and encoded by a speech encoding unit 3 and sent to an RF transmission processing unit 4 where it is channel-encoded, modulated and transmission-processed so as to be transmitted over an antenna 11. A signal received over the antenna 11 is reception-processed, demodulated and channel-decoded so as to be expanded and decoded a speech decoding unit 6. A recording/playback control unit 8 controls writing of a signal from the speech encoding unit 3 to a semiconductor memory 7 or readout of a signal from the semiconductor memory 7 to the speech encoding unit 3. This enables the semiconductor memory 7 to be efficiently utilized in single/dual communication without increasing the circuit construction.
