PURPOSE:To recover the form easily in electrifying an arbitrary heating element, and enable the adaptation to various operational positions to be conducted by building a plurality of heating elements in a high polymer shape memory member in a shape of wire, rod, plate, cylinder or the like, and constituting them as being capable of connecting to electric sources individually by means of an external signal. CONSTITUTION:For instance, heating elements 2a, 2b are electrified which are in a position to apply deformation with respect to a shape memory member 1 molded in a shape of linear, and then the part is heated by the temperature of being glass transferring point or higher and melting point or lower. In the condition, it is added with an external stress, and the part wherein the heating elements are positioned is applied with a curve-shaped deformation, and then the electrification to the heating elements is stopped in order to cool the part up to the glass transferring point or lower and fix the form thereof. In the next place, an external signal such as light, magnetism, electricity, pressure, displacement, sound or the like is sent to a control circuit 5, and the electric source 4 and heating elements 2a and 2b are connected to each other and electrified then, and when heated to the glass transferring point or higher, they return to the original condition in recovering the memory of the linear shape. |
