Abstract: In contrast, the alkaline compound included in the composition of the Document D1 is strong alkali, such as sodium hydroxide. Therefore, the oxide of an alkaline earth metal used in the amended invention is not disclosed or suggested in the D1 at all. In addition, the composition of D1 is an oxygen scavenger and it includes compound which enhance the reaction of oxygen with hydrogen, such as catalyst. Therefore, its hydrogen generating ability is lower than that of the claimed invention.

Abstract: (EN) A charger which can charge a secondary battery suitably with a simple device without particularly requiring fuel supply control, and in which overload to a fuel cell is hard to occur.

Abstract: (EN) A liquid constant-rate emitting apparatus that in the event of delivering a liquid, such as water, from a liquid accommodating container, even when the amount thereof is small, is capable of constant-rate delivery thereof. There is provided an apparatus comprising liquid accommodating container (2) for water accommodation; water lead-out pipe (11) for water emission from the liquid accommodating container (2); gas accommodating container (1) for compressed air accommodation; and introduction pipe (6) for feeding of the compressed air within the gas accommodating container (1) into the liquid accommodating container (2), so that constant-rate water emission from the water lead-out pipe (11) is attained by application of the compressed air to the liquid within the liquid accommodating container (2).
