    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 fuel cell system and a method of operating the same is provided that is capable of reducing degradation of a cathode catalyst of a fuel cell. A fuel cell system is provided that includes a fuel cell having a catalyst used for an anode, wherein a carrier of the catalyst is composed of a material with a property where electric resistance in an oxygen containing atmosphere is greater than electric resistance in a hydrogen atmosphere; and a control device configured to control the fuel cell, when supply of fuel gas is stopped during stoppage of operation of the fuel cell, to consume all or part of the fuel gas in a fuel gas chamber, followed by introducing oxygen containing gas into the fuel gas chamber.
