Abstract: To provide a motion training apparatus capable of appropriately continuing motion training. A controller of a motion training apparatus detects a position of an operation unit moving in an XY plane and controls an X-axis direction drive motor and a Y-axis direction drive motor in accordance with a first speed vector based on a magnitude of a resultant force F0 of a force Fx in an X-axis direction and a force Fy in a Y-axis direction detected by a force sensor when the position of the operation unit is within a predetermined target area TR, and controls the X-axis direction drive motor and the Y-axis direction drive motor so that the operation unit moves in accordance with the first speed vector and a second speed vector acting to return the operation unit.

Abstract: A sound source separation system includes: a controller that: acquires pieces of sound collection data with microphones that collect sounds output from first and second sound sources. The first sound source is at a first position at which effective distances from the microphones are equal and the second sound source is at a different position. The controller further acquires, based on the sound collection data, frequency spectra in two dimensions of a circumferential direction of a circle and a time direction. The first position is a center of the circle and each of the effective distances is a radius of the circle. The controller further separates, from the frequency spectra, a first sound source spectrum and a second sound source spectrum.

Abstract: A membrane-electrode assembly including a catalyst layer that includes a catalyst-supporting carrier in which a catalyst is supported on a carrier made of an inorganic oxide, and a highly hydrophobic substance having a higher degree of hydrophobicity than the inorganic oxide, the catalyst layer being formed on at least one surface of a polymer electrolyte membrane. It is preferable that, in the membrane-electrode assembly, the degree of hydrophobicity of the highly hydrophobic substance is from 0.5 vol % to 45 vol % at 25° C., the degree of hydrophobicity being defined as a concentration of methanol (vol %) when a light transmittance of a dispersion obtained by dispersing the highly hydrophobic substance in a mixed solution of water and methanol reaches 80%.
