And the container 11 is relatively shifted to the direction of the arrow mark and the thin film 23 is closely attached to the opening 11a face and further, the container is pushed up. Then the thin film 23 is cut off at the cut line 26 and closely stuck on the opening 11a to hermetically seal the opening. Thereafter, the container 11 sealed with the thin film 23 at the opening 11a is irradiated with electron beam to sterilize it in a sterilizing device.  And hence, there is no fear that bacteria penetrate from the container opening therein while the container 11 is transferred from the sterilizing chamber to a charging process of the contents.

The Half the signal transmission bit rate is select to be the cut off frequency of the high pass filters 23, 24. Thus, the beat component caused in the demodulated wave and the deterioration in the sensitivity and the error rate due to 1/f noise are reduced.

Abstract: PURPOSE:To automatically search a head of nonvideo-recorded part of a partially video-recorded magnetic tape by providing an operating key, a control signal detecting circuit, a discriminating circuit and an operation control circuit. CONSTITUTION:When the device main body is set under a fast forward mode by operating an operating key 16 to be pressed, a control signal recorded with a video signal on the partially video-recorded magnetic tape is detected by the control signal detecting circuit, and its detecting signal is sent out to a discriminating circuit 13. The presence of the control signal recorded on the magnetic tape 11 is discriminated by the discriminating circuit 13 based on this detecting signal. Then, when no control signal is detected, since this part of the magnetic tape 11 is the nonvideo-recorded part, a nonvideo-recorded part detecting signal is sent out to the operation control circuit 15. The device main body is shifted from the fast forward mode to a stop mode by the operation control circuit 15 with this nonvideo-recorded part detecting signal. By this method, the head of the nonvideo-recorded part of the partially video- recorded magnetic tape is automatically searched.
