    Abstract: A method for manufacturing a copper alloy of the present invention is a method for manufacturing a Cu—Ni—Sn-based copper alloy and includes: a first aging treatment step of performing an aging treatment in a temperature range of 300° C. to 500° C. using a solution treated material; an inter-aging processing step of performing cold working after the first aging treatment step; and a second aging treatment step of performing an aging treatment in a temperature range of 300° C. to 500° C. after the inter-aging processing step. In the first aging treatment step, a peak aging treatment is preferably performed. In addition, in the second aging treatment step, the aging treatment is preferably performed for a short period as compared to that of the aging treatment in the first aging treatment step. In the inter-aging processing step, cold working is preferably performed at a processing rate of more than 60% to 99%.

    Abstract: A power generation element of inverse magnetostrictive type has: a first power generation part including a first magnetostrictive rod made of magnetostrictive material, a first coil wound around the first magnetostrictive rod, and a first magnetic rod having appropriate rigidity and a shape to apply a uniform compressive force or tensile force to the first magnetostrictive rod and being placed in parallel with the first magnetostrictive rod; a frame made of magnetic material bent in a substantially U shape, whose one end and other end across the bent location constitute a fixed end and free end, respectively; and a magnet. The power generation element can suppress the loss of kinetic energy while vibrating so that vibration will last long. The power generation element can be used in an actuator.

    Abstract: A signal detection circuit includes: a VCO that generates a reference signal; a complex signal generation circuit that generates a complex signal from an input signal and the reference signal; a vector operation circuit that calculates an argument of the complex signal by performing a vector operation; and a subtracting phase comparator that compares the argument with a phase of the reference signal by calculating a difference between the argument and the phase of the reference signal, wherein the complex signal generation circuit includes: a multiplication circuit that multiplies the input signal by the reference signal; and an HPF that removes a DC component from a signal output from the multiplication circuit.
