A container was prepared which had a pipe connected to a high-pressure W1 elementary gas blowing device as shown in Factor 2, and a silicone rubber base having a concavity angle with a radius of curvature of 180 cm. However, '4a' was designed so that the stand and container could be separated and installed. After that, the previously obtained multi-cell was placed on the stand from which the container had been removed.

切溝に清ってマルチセルが切断された。At this time, the multicells were arranged so that the grooves formed in the multicells faced the lower axis. Next, after a container was loaded onto this table, nitrogen gas was introduced into the container from a still-pressure bulk waste ejection device. As a result, the multicell was cut by cutting into the groove formed in the horizontal direction. Next, after returning the pressure inside the container to atmospheric pressure and removing one container from the stand, we rotated the multicell by an angle of 90 degrees **-, and then repeated the above procedure and that of my colleague. The multicell was cut by cutting grooves formed in the perpendicular direction.
