IPC: H04N5/92
Filed: 1990-09-03
Abstract: PURPOSE:To prevent an error rate of a reproduced PCM signal from being deteriorated by applying AC bias recording of a QDPSK signal to a depth of a magnetic tape and recording a video signal to an upper layer of the magnetic tape. CONSTITUTION:The VTR is provided with a band pass filter 34 limiting the band of a bit string DQ from a 2/4 conversion circuit 33 and outputting a QDPSK signal SQ and an oscillation circuit 38 for an AC bias signal SB. The QDPSK signal SQ is fed to 1st rotary magnetic heads 1A, 1B together with an AC bias signal SB to apply AC bias recording to an upper layer part and a depth of a magnetic tape 4, a video signal SV is fed to 3nd rotary magnetic heads 2A, 2B to record the video signal SV to the upper layer while erasing the QDPSK signal SQ at the upper layer part. Since the signal is converted by the 2/4 conversion circuit in a pure digital way, the phase of a carrier signal of an 0-QDPSK signal is not fluctuated due to temperature. Thus, the deterioration in the error rate of the reproduced PCM signal DR is prevented.

Filed: 1988-09-19
Abstract: PURPOSE:To certainly detect the abnormality of the working of a brake by detecting the abnormality of the brake when there is no change of brake response input within a specified time after brake operation command is generated. CONSTITUTION:When an operation command is issued at time ts, inverter output current is increased with a time lag, and at time t1 when it reaches a normal value I, brake operation specifying output (release command) is obtained. When a brake responds, brake response input is obtained, but if the brake response input is not obtained from the brake operation specifying output within a normal T1, it is set to be in an abnormal state. When the operation command is broken at te, the output frequency is lowered, and when it is turned into F, the brake operation specifying output is generated at time t3. As a result, if the brake responding input is not obtained within a normal time T2, it is set to be in the abnormal state.
