摘要： PURPOSE:To reform unbalance of motion due to a delay in the cooling speed of shape memory alloy wires and to enable increase of a speed, by a method wherein a machine spring is mounted to an actuator employing a pair of shape memory alloys wires. CONSTITUTION:A slider 13 is coupled to a pair of shape memory alloy wires 1 and 2 therebetween. A machine spring 3, having a set load being an intermedi ate value between a load under the high temperature state and a load under the low temperature state of the shape memory alloy wires 1 and 2, is coupled to either of the shape memory alloy wires 1 and 2. After the one shape memory allow wire 2 is heated and the other shape memory alloy wire 1 is cooled, and when, conversely, the shape memory alloy wires are cooled and heated, a delay in the cooling speed of the shape memory alloy wire 2 being cooled is compensated through expansion of the machine spring 3.

摘要： PURPOSE:To generate driving power by making excellent responsive use of a formal change by inserting a small pipe made of shape memory alloy into a large pipe and providing a means of forcibly flowing at least either of cooling or heating liquid into a clearance between both the pieces and the inside of the small pipe. CONSTITUTION:A small cylindrical pipe 2 is inserted into a large cylindrical pipe 1, and flow paths 3a, 3b are formed between the pipes 1, 2 and in the cylindrical pipe 2 respectively. Both the pipes 1, 2 are made of shape memory alloy respectively and fixed to a base 4 and an end plate 5. When a control valve 9 of piping 10 is closed by a control device 12, and both the pipes 1, 2 are heated through lead wires 11a, the pipes 1, 2 make an effort to shrink into a form kept in memory at high temperature to generate recovering force. Since the recovering force is stronger than the bias force of a compression coil spring 7, both the pipes 1, 2 and the spring 7 shrink to lift an object to be driven. On the other hand, when the control valve 9 is opened to supply a cooling liquid between both the pipes 1, 2 and in the cylindrical pipe 2 from its supply source, the pipes 1, 2 and the spring 7 elongate to lower the object to be driven.

摘要： PURPOSE:To aim at the promotion of sharp reduction in a space for assemblage to various devices, by utilizing the expansion and contraction of a form memory alloy wire guided by a guide tube, while dispensing with the space required for three-dimensional or plane form variations in the alloy wire heretofore in use. CONSTITUTION:When a form memory alloy wire 12 is energized with a continuous rating current and heated with a switch turned on, this alloy wire 12 tries to be restored to its memory form, but since the form is restrained by a guide tube 11, it contracts as far as the whole length as leaving its form almost unchanged intact. Therefore, a bias spring 21 is stretched out, and an actuator 19 comes to a backward position (left). Next, stopping the energizing and heating by the current with the switch 23 turned off, when an on-off valve 25 is opened and compressed air is passed through the inside of the guide tube 11, the alloy wire is quickly cooled, losing its contracting force, and stretched out by tension of the bias spring 21 whereby the actuator 19 goes back to a forward position. With repetitions of the above motion, as an actuator it quickly acts, and it has flexibility so that assemblage to various devices is convenient enough and, what is more, the space also is reducible.
