The aim of the invention is to provide an underwater thawing and freezing device using complex wave motions, being a freezing and thawing device used from restaurant to family, capable of processing much fresh food by one device. The underwater thawing and freezing device includes: a thawing and freezing tank for containing therein ethyl alcohol water as a thawing and freezing liquid; a plurality of wave motion piezoelectric vibration elements for generating wave motions in the thawing and freezing tank; a temperature control unit for controlling a temperature of the ethyl alcohol water at a predetermined temperature, the temperature control unit having a temperature sensor for detecting the temperature of the ethyl alcohol water; and a control unit for controlling the wave motion piezoelectric vibration elements. The plurality of wave motion piezoelectric vibration elements generate wave motions at a plurality of different frequencies. The wave motions travel at an angle of an about 10 degrees inclined from a vertical line from a surface of the thawing and freezing tank, on which the respective wave motion piezoelectric vibration elements are provided.

Provided is a method for shutting down an indirect internal reforming SOFC, in which a hydrocarbon-based fuel is reliably reformed, and the oxidative degradation of the anode can be prevented by a reformed gas. A method for shutting down an indirect internal reforming SOFC including a reformer; an SOFC; a combustion region for combusting the anode off-gas of the SOFC; and an enclosure for housing the reformer, the SOFC, and the combustion region, wherein the method includes causing the flow rate of a fuel supplied to the reformer to become FE from FS; and stopping the supply of the fuel to the reformer when an anode temperature becomes lower than the oxidative degradation temperature, where FE represents a flow rate of the fuel supplied to the reformer in a state in which the anode temperature is steady and lower than the oxidative degradation temperature, in which in the reformer the fuel is reformed and a reformed gas with a composition suitable to be supplied to an anode is produced, and in which an amount of the reformed gas produced is equal to or more than the requisite minimum flow rate for preventing the oxidative degradation of the anode when the anode temperature is a temperature equal to or higher than the oxidative degradation temperature, and FS represents a flow rate of the fuel supplied to the reformer at the start of the shutdown method. Also provided is an indirect internal reforming SOFC appropriate for this method.

A condensate demineralization method for a condensate treatment of a nuclear power generation plant, including: passing condensate at a linear flow rate ranging from 20 m / h to 200 m / h through a condensate demineralization apparatus (6) comprising an ion exchange resin layer filled therein wherein the ion exchange resin layer includes a mixed bed of a strongly acidic cation resin and a strongly basic anion resin and a metal doped resin in a volume ratio ranging from 2% to 50% relative to the mixed bed.

The present invention provides: a production method that is for a glyceryl ether-containing composition and that comprises a deodorization step for bringing a glyceryl ether-containing product selected from monohexyl glyceryl ether-containing products, monocyclohexyl glyceryl ether-containing products, and mixtures thereof into contact with water vapor in an environment having a reduced pressure of 0.10-10 kPa for 60-600 minutes, and an addition step for adding 0.05-0.30 parts by mass of an antioxidant containing d-alpha-tocopherol to 100 parts by mass of the glyceryl ether-containing product; and a glyceryl ether-containing composition having specific amounts of a specific glyceryl ether and an antioxidant containing d-alpha-tocopherol.

The present invention provides a refrigerator which realizes increase of food storing space and cost reduction, and can prevent oxidation deterioration of nutrition components in the food stored in a decompression storing chamber. The refrigerator is provided with an anti-oxidation component release box (80) with antioxidant at the inner part at the storing chamber formed in the refrigerator. Theanti-oxidation component release box (80) is configured to the inner part of the decompression storing chamber (24) which is closed and depressurized to a pressure state lower than the atmosphere in food storing. The antioxidant which releases the anti-oxidation component for a large amount in the pressure state lower than the atmosphere state is used.

The provision of an oxygen-absorbing multilayer body that has the following: an oxygen-absorption layer that contains an oxygen-absorbing composition; and a thermoplastic-resin layer that contains a thermoplastic resin (b). The oxygen-absorbing composition contains at least one tetralin-containing compound that can be represented by general formula (1), a transition-metal catalyst, and a thermoplastic resin (a).
