Abstract: A medical capsule device includes a capsule body provided with a chamber inside and a communicating path for communicating the chamber with the outside, a movable member arranged in the chamber and movable between a liquid-pushing position at which the volume of the chamber is made smallest and a liquid-receiving position at which the volume of the chamber is made largest, a coiled operating member made of a shape memory alloy for selectively moving the movable member to the liquid-receiving or -pushing position according to temperature changes of the operating member itself, and a switching circuit and power supply source arranged in the capsule body and adjusting the temperature of the operating member to selectively move the movable member to the liquid-pushing or -receiving position.

Abstract: An air conditioning system comprises a first air duct having an inlet port and an exhaust port opening into a room, a room air circulating fan for introducing the air inside the room into the first air duct through the inlet port and discharging the air into the room through the exhaust port of the first air duct, solar heat collector for producing hot air by utilizing solar heat, a second air duct adjacent to the first air duct on the inlet port side thereof, hot air feeding fan for feeding the hot air from the solar heat collector into the second air duct, a rotary total heat exchanger for dehumidification disposed between said first and second air ducts so as to extend severally in the two ducts, a third air duct adjacent to the first air duct on the downstream side of the rotary total heat exchanger, outside air feeding fan for feeding the outside air into the third air duct, a stationary multi-diaphragm-type sensible heat exchanger for cooling disposed between the first and third air ducts so as to be lo

Abstract: A hot air type solar heat-collecting apparatus comprises a first transparent plate, a second transparent film located thereunder, and a corrugated metal plate mounted on the underside of a second transparent film to absorb the sunlight. The metal plate forms a first group of air passages on the upperside thereof and a second group of air passages on the underside thereof.
