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.

The peeling member is disposed inside the inner tank. The switching mechanism is provided for switching between the state of rotating the peeling member in the interlocking manner with the inner tank and the state of being disconnected the peeling member from the inner tank. With the peeling member disconnected from the inner tank, one of them is rotated, the used paper diaper stored is peeled off from the inner surface of the inner tank, and then, the used paper diaper processed in the processing tank is discharged from the bottom of the processing tank to the take-out unit via the opening and closing unit.

Used paper diaper processing apparatus

Provided is a used paper diaper processing apparatus in which a water absorption function of a superabsorbent polymer that absorbs water contained in excrement is lowered and water is removed by mixing the superabsorbent polymer and a chemical containing divalent metal ions in an outer tank, and in which weight is reduced by dehydration after an amount of water contained in a used paper diaper is lowered. In the apparatus, a lower portion of the outer tank can be opened and closed, so that weight reduction processing and a series of operations including taking-out are possible. Since an operator is not required to take out the used paper diaper after processing directly from the outer tank, it is possible to reduce work and hygiene burdens on the operator.

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.

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.

Vapor-phase type heating method and vapor-phase type heating apparatus

A vapor-phase type heating method includes: collecting, in the vapor tank, the heat transfer liquid which has come into contact with a heating target object, has cooled to liquefy, and has fallen down as droplets from a front surface of the heating target object to a lower portion of a heating furnace; resupplying, to the heating furnace, heated gas to which the vapor has been supplied and which has been formed by supplying the vapor from the vapor tank to heated gas obtained from heating the heating target object discharged from the heating furnace to a circulation pathway; and heating the heating target object, at a predetermined rate of temperature rise in a state of an even distribution of the vapor of the heat transfer liquid by maintaining the vapor of the heat transfer liquid in a predetermined amount in the heating furnace by the collection and the supply.

Provided is a solvent separation method and a solvent separation apparatus in which a vaporized solvent is collected at one internal side of a solvent separation unit by attracting the vaporized solvent based on electric field, while the vaporized solvent is prevented from coming into contact with electrodes, and the collected solvent is discharged from the solvent separation unit. Different electric fields are alternately applied to a pair of first electrodes and a pair of second electrodes present at predetermined locations inside a tetragonal tubular solvent separation unit to attract a vaporized solvent toward the second electrodes. Thus, the vaporized solvent is collected in a space between the second electrodes inside the solvent separation unit, and the collected solvent is discharged from the solvent separation unit, together with a portion of the exhaust atmosphere present around the collected solvent.

Solvent separation method and solvent separation apparatus

An electrode is arranged on one wall surface of a flow path of an exhaust atmosphere in a solvent separating apparatus, an electric field is applied to vaporized solvent in the exhaust atmosphere so as to concentrate only the solvent in the exhaust atmosphere in the direction toward the electric field, and the solvent is discharged to the outside of the solvent separating apparatus together with a portion of the exhaust atmosphere in the periphery of the solvent.
