Abstract: A water supply apparatus is arranged inside a house body and includes a watering apparatus that performs watering to a cluster of plants from above. The watering apparatus supplies water to the plants and controls an ambient temperature of the plants due to heat transfer utilizing vaporization heat by watering. A control apparatus acquires an environment information including the ambient temperature of the plants from an environment sensor, and performs the watering by driving the water supply apparatus in a watering period determined according to the environment information, and prohibits the watering by the water supply apparatus in an idle period that is set after the watering period so as to obtain a temperature and a humidity appropriate for growth of the plants.

Abstract: There is provided a method for decomposing a cured epoxy resin, the method being capable of decomposing a cured epoxy resin containing silica efficiently. A cured epoxy resin containing silica is decomposed by being brought into contact with subcritical water including at least one alkaline compound selected from an alkaline metal salt and an alkaline metal hydroxide.

Abstract: A carbonate spring bath system creates a bath water dissolved with CO.sub.2 gas and supplies the same to a bathtub. The system includes a source of a concentrated CO.sub.2 gas, a circulation path connected to the bathtub and including a booster pump for circulating a bath water from and into the bathtub. CO.sub.2 gas and air supply lines are connected to the circulation path upstream of the pump. The CO.sub.2 gas and air supply lines includes valves which are opened and closed to provide the CO.sub.2 gas and the air at a suitable mixture ratio such that the CO.sub.2 gas and air are forced to dissolve in the pressurized bath water. Disposed downstream of the pump is an accumulator for separating undissolved gas in the bath water and storing in a gas chamber the undissolved gas emanating from the bath water. A recycle line connects the gas chamber to the circulation path upstream of the pump to return the undissolved gas to the circulation path.
