Filed: 1982-05-14
Abstract: PURPOSE:To improve the frequency characteristics of an audio signal by attaching audio heads to a rotary cylinder together with video heads for recording and reproduction. CONSTITUTION:A video signal is recorded and reproduced on and from a magnetic tape 3 by the video heads 2a and 2b attached to the rotary cylinder 1.

The audio heads 5a and 5b attached to the rotary cylinder 1 are at right angles to the video heads 2a and 2b and at different height positions and their azimuths are different by tens of degrees in the opposite directions, so a magnetic pattern slanting to tracks 6 at 45 deg. is recorded on the magnetic tape 3. Further, an audio carrier is set to a low level to make deterioration of a previously recorded video signal inconspicuous. Further, the audio heads differ in height from the video heads, so a video signal recording part free of the influence of the audio carrier is obtained.

Abstract: PURPOSE: To enable perfect protection to be performed by so operating the device that abnormal signal is outputted by detecting the approach of an abnormally thick protion to the rolling mill and the bite of the abnormal thick portions is prevented based on this signal.  
     CONSTITUTION: A plate thickness detector 8 detects the thickness of the incoming rolling material and outputs the signal Δh proportional to the deviation between the target value and the actual plate thickness.

A shear 9 is operated based on this signal and a rolling mill 5 and uncoiler 2 stop. At the same time, the signal for opening the roll gap at the maximum speed is emitted to a screw-down device 7, by which the breakdown of the rolling mill is perfectly prevented.
