    摘要： A liquid level detector includes: a detecting element having one surface and the other surface opposite to the one surface, the one surface being opposed to a liquid, while being parallel to a height direction of liquid level; a Peltier element provided on the other surface side of the detecting element; and a control unit performing a detection processing for a liquid level of the liquid. The Peltier element forms a heat flow passing through the detecting element from the other surface to the one surface, toward the liquid or a gas. The control unit calculates a liquid level on the basis of an output value of an electrical signal outputted according to the heat flow passing through the detecting element, and a relationship between an output value of the detecting element and a liquid level.

    摘要： A support device comprises a piston rod and a fixed member arranged so that a target object is placed therebetween, and an elastic member is provided to the target object side of the fixed member. A monitoring device includes a heat flux sensor and a detection part. When the target object is supported between the piston rod and the fixed member due to force applied by the piston rod, the heat flux sensor outputs a signal corresponding to the heat flux flowing between the elastic member, which is compressed by the load applied from the piston rod, and the fixed member. Based on the signal output by the heat flux sensor, the detection part detects the support state of the target object supported by the support device, or the size of the target object.

    摘要： A method of manufacturing a thermoelectric converter includes filling each of a plurality of through-holes in each of a plurality of resin films with fillers containing a plurality of thermoelectric material particles. At this time, a part of the filler is extruded from each through-hole. In this state, the plurality of resin films are stacked together. A top-surface protection member having top-surface conductor patterns is stacked on one side of the plurality of resin films. A back-surface protection member having back-surface conductor patterns is stacked on the other side of the plurality of resin films. Thus, an integrated stacked body is formed. The integrated stacked body is then heated and pressurized. A plurality of thermoelectric material particles are thereby sintered to form the first and second thermoelectric members.

    摘要： 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.

    摘要： A wind direction meter has the following plurality of sensors and a control unit. Each sensor has a first surface and has first and second interlayer connection members made of different metals or semiconductors. Further, the wind direction meter includes a thermoelectric conversion element which generates an electrical output when a temperature difference occurs between first ends and second ends of the respective first and second interlayer connection members. The sensor generates an electric output when the surrounding air, whose temperature has been changed by a heater, is moved by the wind to produce a temperature difference between the first ends and the second ends of the first and second interlayer connection members. The control unit calculates the direction of the wind on the basis of the difference in output. Thus, the wind direction of a weak wind can be detected with the wind direction meter.

    摘要： 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.
