Since the bits from 0-th to 59-th in a writing buffer correspond to the bits from 0-th to 59-th in the edition buffer, they can be copied as they are from the writing buffer to the edition buffer without requiring a bit system. Since the 60-th and 61-th bits of the edition buffer correspond to the 0-th and first bits of the writing buffer, the 4-th and 5-th bits in a byte 1 obtained by shifting the 0-th byte in the first line of the writing buffer can be dot copied to the 60-th and 61-th bits of the edition buffer.

Abstract: PURPOSE:To prevent malfunction when transmission signals are transmitted at the same time from plural terminal devices by detecting an amplitude modulation component of an output of an FM detecting circuit of an FSK demodulator to discriminate the presence of radio interference. CONSTITUTION:The FSK demodulator 10 amplifies a received return signal VB, after a limiter eliminates the amplitude modulation component and the signal is FM-detected, and a data signal VD' comprising a base band signal is demodulated by detecting the level of its detected output VF at a comparator circuit 15.

A radio interference discriminating section 18 discriminates the presence of radio interference by detecting the amplitude modulation component (frequency 2DELTAf) included in the detected output VF of the FM detecting circuit 14 of the FSK demodulator 10. The transmission of a transmission signal VT is stopped by a radio interference signal VM outputted from this ratio interference discriminating section 18.

Filed: 1990-03-30
Abstract: PURPOSE:To reduce the manufacture cost by reading a reproduction signal written in a picture memory when other magnetic head scans a same location in place of a reproduction signal from one magnetic head not used for the reproduction and matching both the signals. CONSTITUTION:A reproduction signal from one magnetic head Rb not used for reproduction due to a cause to contention of simultaneous scanning of magnetic heads, e.g. Ra, Rb of the same azimuth angle is supplemented by using a reproduction signal written in a picture memory 12 when the magnetic head Ra scans the same location in place of the reproduction of the magnetic head Rb. Moreover, the deviation of a time axis between the deputy reproduction signal and the reproduction signal form the magnetic head Rb is matched by retarding the reproduction signal from the magnetic head Rb with a time difference between write and read state. The storage capacity of the picture memory 12 required for the special reproduction is decreased to 1/3 of the capacity of the field memory by utilizing the two functions effectively.
