Embodiments of the invention include a system for integrated circuit development. When the stop instruction of the stepping motor 49 occurs based on the instruction from an external, the main CPU 31 drops the voltage value added to the stepping motor which is rotating at the constant speed to the voltage value lower than such voltage value and executes the stop process of the stepping motor 49 by 2-phase excitation. The mesh structure is designed to allow such permeable bag to expand to a predetermined size or shape under certain pressures, and further allows exudation of said bone void filler through its walls.
