WATER REPELLENTLY TREATED OIL/WATER SEPARATING FILTER AND ITS PRODUCTION 撥水処理をした油水分離フィルターとその製造方法 - 特許庁
Highly efficient heat storage is achieved by directly dropping hot water in a heat storage structure 23 whose inside is water-repellently finished, the dropped hot water can be circulated in a heat collector as it is by making the heat storage structure absorb a heat amount instantly from the hot water, and the hot water is not needed to serve as the heat storage body. 内部を撥水処理した蓄熱構造体23内の温水を直接滴下することで高効率な蓄熱を実現、蓄熱構造体が温水から即時に熱量を吸収することで、滴下した温水をそのまま集熱器に循環でき、温水を蓄熱体とする必要が無い。 - 特許庁
