Abstract: An energy conversion device includes a first acoustic wave generator, a second acoustic wave generator, and an output unit which are provided in a pipe member. The first acoustic wave generator has a thermal energy generator configured to generate thermal energy from electric energy, and converts the thermal energy generated by the thermal energy generator into acoustic energy to generate acoustic wave in working gas by a self-excited thermo acoustic vibration. The second acoustic wave generator converts thermal energy supplied from a heat supply source into acoustic energy and generates acoustic wave in working gas by a self-excited thermo acoustic vibration. The output unit converts the acoustic energy of the acoustic waves from the first acoustic wave generator and the second acoustic wave generator into cold energy to output.

Abstract: A thermal flow-rate sensor includes: a first temperature sensor that detects the temperature at a specified location of the outer-wall surface of a pipe; a heat-transfer element that is arranged on the outer-wall surface of the pipe in a state separated from the first temperature sensor, and that exchanges heat with a measurement medium by heating or cooling the outer-wall surface of the pipe; a second temperature sensor that detects the temperature of a portion of the outer-wall surface of the pipe that is heated or cooled by the heat-transfer element; and a control unit that performs specified processing. A heat-flux sensor is arranged between the heat-transfer element and the outer-wall surface of the pipe and directly detects heat flux between the heat-transfer element and the pipe; and the control unit detects the flow rate of the measurement medium based on the temperature that is directly detected by the first temperature sensor, the temperature that is detected by the second temperature sensor, and the heat flux that is detected by the heat-flux sensor.

Abstract: In a radiant heat sensor, first and second thermoelectric members are alternately arrayed one by one in a direction along a first surface of a plate-shaped member so as to be separated from each other, and each of the first and second thermoelectric members configure a portion of the first surface. First conductor patterns extend the first surface, disposed on the first surface so as to span a single first thermoelectric member and a single second thermoelectric member that are adjacent to each other, and configure hot contact portions between the first and second thermoelectric members. Second conductor patterns extend along the first surface, disposed on the first surface so as to span a single first thermoelectric member and a single second thermoelectric member that are adjacent to each other, and configure cold contact portions between the first and second thermoelectric members.

Abstract: An actuator includes a rod, an electric motor to generate a rotational driving force on supply of electricity, an output shaft to output the rotational driving force of the electric motor to the rod, a feed screw mechanism, and a rotation prevention mechanism. The feed screw mechanism includes a female screw portion formed on one of the output shaft and the rod, and a male screw portion formed on the other to mesh with the female screw portion. The rotation prevention mechanism is configured to regulate rotation of the rod caused by the rotational driving force of the electric motor.
