摘要:
A non-vent type fully openable easy-opening end has a principal score around the periphery of the end, and a pair of beads which run in a tearing direction. The pair of beads is formed symmetrically at both sides of a tab securing portion of the end which is in the vicinity of the tab securing score. A pair of second beads may also be formed on the periphery of a removable portion of the end which is defined by the principal score in such a manner that they run along the principal score. The second beads are located symmetrically on both sides of the tab securing portion. A straight line l that connects the forward end of the tab securing portion and the starting end of each of the first beads or the starting end of each of the second beads is inclined with respect to the tearing direction at an angle ranging between 45 degrees and 85 degrees. A distance a between the finishing ends of the first beads and the center of the tab securing portion in the tearing direction is equivalent to or larger than the diameter of the tab securing portion and is not less than 4 mm.

In current transmitting methods, an instantaneous interruption of a transmission data may occur at the time of switching a system. A sending method of the present invention is a sending method for transmitting a data string signal to a primary system and a backup system in which: a first periodic signal which becomes a reference signal and a second periodic signal with a longer cycle period than the first periodic signal are generated; a data string signal is synchronized with the first periodic signal; and the data string signal synchronized with the first periodic signal is multiplexed by a cycle period synchronized with the second periodic signal to transmit it to the primary system and the backup system. A receiving method of the present invention is a receiving method for receiving a data string signal multiplexed by a predetermined cycle period from a primary system and a backup system in which: synchronous processing of reception signals received from a primary system and a backup system is performed; processing for aligning phases of reception signals which are received from the primary system and the backup system and on which the synchronous processing has been performed with the phase of the predetermined cycle period is performed; and switching between a reception signal which is received from the primary system and on which said phase alignment processing has been performed and a reception signal which is received from the backup system and on which phase aligning processing have been performed is performed.

After an audio signal at a given level is recorded, the recording level is changed and a video signal is recorded. The audio and video signals are reproduced. A first recording level at which the reproduced video signal becomes the maximum level, a second recording level which is smaller than the first recording level and at which the reproduced video signal level becomes the maximum value.times.0.9, a third recording level at which the reproduced audio signal level is equal to or greater than a reference value, and a fourth recording level at which the reproduced audio signal level becomes equal to or greater than the minimum value are stored in storages, respectively. The video head recording current value is controlled according to the optimum recording level found by an arithmetic section based on the stored recording levels.

Each of radio frame multiplexing circuits generates radio frame data by multiplexing multiplexed data inputted from a LAN terminating circuit, into the transmission area of a radio frame, and by assigning the transmission area of the radio frame other than the area, to which LAN-received data is assigned, as the transmission area of PDH data signal strings; inserts data assignment information into a radio over-header; and transmits the data from a radio transmitting/receiving circuit to a remote device via a transmission line. Each of radio frame demultiplexing circuits demultiplexes the multiplexed data based on the data assignment information in the radio over-header.
