bottom surface

12,14 places, two second sides, be formed with step between the second pilot trench 161 and the first pilot trench 160, the second pilot trench 161 is semi open model, the cell wall that the second pilot trench 161 is formed with projection at

contiguous end face

11,14 places, two second sides does not then have the cell wall restriction around this second pilot trench 161 at adjacent floor 12 places, thereby forms opening.Be formed with respectively draw-in groove 17 on the second side 14.Also be provided with wire 18 on the end face 11, wire 18 1 ends are connected with lens group 20, and the other end extends to contiguous holding tank 16 places on the first side 13.
