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%.

There can be provided a method for manufacturing a diamond substrate which can sufficiently suppress dislocation defects, a high-quality diamond substrate, and a freestanding diamond substrate.
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:
An activity amount calculation system (100) includes a plurality of detection units (D1, D2) and an activity amount calculation device (10). The plurality of detection units (D1, D2) detect a resident and output detection signals when the resident passes through doorways of a plurality of rooms. The calculation device (10) includes a calculation unit (11) and a summation unit (12). Upon detection of the resident by the detection units (D1, D2), the calculation unit (11) calculates an activity amount of the resident based on relationships between detection units and reference activity amounts. The summation unit (12) repeatedly calculates a total activity amount of the resident in a predetermined period by summing activity amounts calculated by the calculation unit (11).
Abstract:
This dynamic damper is provided with a movable part that can be moved by external input, and an excitation coil for generating a magnetic field of an intensity corresponding to a supplied electric current. The movable part is configured to include: first and second magnetic cores in which magnetic paths, which are pathways for the magnetic field generated by the excitation coil, are configured as annular closed magnetic paths; and a magnetic viscous elastomer of which the viscous properties change in accordance with the size of the magnetic field generated by the excitation coil. The magnetic viscous elastomer is arranged so as link at least one location in the first and second magnetic cores and constitutes a closed magnetic path.
