In some cases, the upper end of the partition wall (a) is pressed downward and curved when it hits the partition wall.As a result, a closed state is not maintained in this suppressing curved part (g), and the suction function in this area is inhibited. However, the other adjacent partition wall is specimen 03.
Since it is in contact with the back surface, even if there is an area (x mark) that is not in a closed state as shown in Fig. 7, the suction function is ensured in the closed area (○ mark) K, and the specimen 03 as a whole is fixed to the jig. There are many things that can be fixed to the main body by adsorption.
