摘要： PURPOSE:To heat effectively only the shape memory part by coating a good electrical conductor layer on the surface of the part of a shape memory alloy where heating is not required except the shape memory part. CONSTITUTION:Both side parts 1a, 1a of a shape memory alloy 1 consisting of a Ti-Ni alloy except the part 1b to be memorized with a shape are coated with good electrical conductors 2, 2 by plating, vapor deposition, etc. Materials 3, 4 susceptible to heat are attached via the conductors 2, 2 to the alloy 1. Conductors 5, 6 are connected to the conductors 2, 2 and electricity is conducted thereto in the stage of heating the part 1b memorizing the shape to deform said part to the memorized shape. Heat is not generated in the part 1a where heating is not required as the current passes through the conductor 2. The current flows to the part 1 to be deformed to the memorized shape by heating and the heat is generated by resistance heat to deform said part to the memorized shape at a prescribed high temp. The current flows uniformly over the entire part through the conductor 2 to the deformed part 1.

摘要： PURPOSE:To constitute the machinery provided with plasticity and a number of degree of freedom as seen with living things by connecting the parts between alloy supporting bodies by >=3 pieces of shape memory alloy and springs and selectively heating the shape memory alloy pieces. CONSTITUTION:At least three alloy supporting bodies Ai are arranged, and the ports between the contiguous alloy supporting bodies Ai are connected by at least three shape memory alloy Bia, Bib, and Bic and springs Ci. Therefore, when the shape memory alloy Bia, Bib, and Bic are selectively heated, each alloy supporting body Ai shifts properly, and said kinetic body is provided with plasticity and a number of degree of freedom as seen in living things, and the curved movement like a snake and the arthromere extending and contracting motion like an earthworm are permitted.
