Abstract: As a temperature measurement apparatus using a surface acoustic wave of a piezoelectric substrate that performs temperature measurement wirelessly and without power supply, the temperature measurement apparatus accurately measures the temperature of the thermocouple tip end by analyzing the frequency characteristics of the surface acoustic wave propagating on the piezoelectric substrate and including temperature information of the piezoelectric substrate, and detecting change in propagation time of the surface acoustic wave of the piezoelectric substrate that is changed by the electromotive force of the thermocouple.

Abstract: In a vapor-phase type heating method, an object is heated by a heated gas containing vapor in a heating furnace. The heat transfer fluid falling from a front surface of the object to a lower portion of the heating furnace is collected, after the vapor comes into contact with the object and cools to liquefy and latent heat of vaporization of the vapor is applied to the object through phase change. The heated gas obtained after heating the object is discharged from an inside of the heating furnace to the circulation route. In the circulation route, the heat transfer fluid is supplied as droplets to the discharged heated gas and is vaporized after heating, and the heated gas including the vapor is supplied to the heating furnace.

Abstract: A liquid treatment device that achieves an effective treatment by forcibly contacting a swirl flow of a hydrogen peroxide-containing treated liquid with a liquid to be treated that has been processed to contain copper ions or iron ions includes a rod-like first electrode, a plate-like second electrode formed of a copper- or iron-containing metal, and a first treatment vessel that causes a liquid to swirl and generate a gas phase in a swirl flow of the liquid. A pulse voltage is applied to the generated gas phase to generate a plasma. The second electrode serves as an anode, and reaches inside of a supply section for a liquid to be treated. The liquid to be treated containing the generated copper ions or iron ions is forcibly brought into contact with hydrogen peroxide generated by the plasma. In this way, the Fenton's reaction effectively takes place, and the liquid treatment performance improves.
