Abstract: A cooling system employs at least one composite elastocaloric device. Each composite device has a first member with a first material and a second member with an elastocaloric material. The first material increases in size in response to an applied electric or magnetic field and returns to its prior size upon removal of the applied electric or magnetic field. The first and second members are mechanically coupled together such that the increase in size of the first material applies a stress to the elastocaloric material and the return of the first material to its prior size releases said stress, thereby causing the elastocaloric material to absorb heat.

Abstract: The magnetostrictive member contains an iron-based alloy crystal having magnetostrictive characteristics and is a plate-like body having front and back faces. In one of the front and back faces, a thickness and a surface roughness Ra of the magnetostrictive member satisfy Expression (1): log Ra≥0.48t−0.62. In Expression (1), log indicates a common logarithm, Ra the surface roughness (μm), and t the thickness of the magnetostrictive member (mm).

Abstract: A magnetic sensor includes a piezomagnetic component which includes a first piezomagnetic element and a second piezomagnetic element that are arranged opposite to each other, a magnetostrictive component which includes a first magnetostrictive element and a second magnetostrictive element arranged opposite to each other on the same side of the first piezomagnetic element and the second piezomagnetic element, respectively, and a piezoelectric component which includes a first piezoelectric element deposited underneath the first piezomagnetic element, a second piezoelectric element deposited underneath the second piezomagnetic element, a third piezoelectric element deposited underneath the first magnetostrictive element, and a fourth piezoelectric element deposited underneath the second magnetostrictive element. The first piezoelectric element and the second piezoelectric element are electrically connected to a power supply circuit, and produce first deformation, which is applied to the first piezomagnetic element and the second piezomagnetic element to produce an alternating magnetic field.

Abstract: A method for producing a magnetostrictive material producible without using a mold, a magnetostrictive material, and a method for producing an energy conversion member; the first method includes melting raw material powder for the magnetostrictive material by a laser or electron beam using a metal 3D additive manufacturing machine to perform additive manufacturing. The raw material powder is composed of an Fe—Co alloy. A method for producing an energy conversion member includes laminating and joining one of a magnetostrictive layer formed by melting raw material powder for a magnetostrictive material by a directed energy deposition method to perform additive manufacturing and a soft magnetic material layer formed by melting raw material powder for a soft magnetic material by the directed energy deposition method to perform additive manufacturing on another.
