<p>PURPOSE:To form a core coil corresponding to temperature change by combining a shape memory alloy deformed in a coil shape and a core. CONSTITUTION:A shape memory alloy wire 2 deformed in a coil shape at the prescribed temperature or above or lower is disposed near a core 1. When becoming the prescribed temperature, the wire 2 is deformed in a coil shape around the core 1. Thus, the core coil corresponding to the temperature change is formed.</p> |
