Abstract: An air clean apparatus including an air intake intended to be located at a lower position in a corner of a room and an air outlet intended to be located at an upper position in the corner of the room, and at least a filter and a blower both inside the air clean apparatus, characterized in that, when the air clean appratus is installed in a room, a given quantity of circulating blowing air, the given quantity is decided according to the height from the floor underneath the air intake and the underside-open area determined on the basis of particles of the maximum size to be eliminated at the air intake.

Abstract: The object is to provide an Air clean appratus that cleans up floating dusts in air in a room and is configured in a shape that can be placed in dead space in a room and will not be an obstacle when it is placed in a room. [Means for Achieving the Object] An Air clean appratus comprising an air intake 13 intended to be located at a lower position in a corner of a room and an air outlet 14 intended to be located at an upper position in the corner of the room, and at least a filter 15 and a blower 18 both inside the Air clean appratus, characterized in that, when the Air clean appratus is installed in a room, a given quantity of circulating blowing air, the said quantity is decided according to the height from the floor underneath the air intake and the underside-open area determined on the basis of particles of the maximum size to be eliminated at the air intake.

Abstract: A mobile hospital system can be moved by tractors, helicopters, railway locomotives and/or sea vessels and provide comprehensive diagnoses and medical treatments to casualties and patients. A plurality of container wagons functionally operate as part of a hospital and are moved appropriately to set up a comprehensive hospital system by connecting the plurality of container wagons on site, some of the container wagons being supplied with water, power and fuel oil from a water supply wagon, a power generation wagon and an oil supply wagon, respectively. With such an arrangement, a comprehensive hospital system can be set up by connecting the plurality of container wagons on site in a region hit by a natural disaster or a harsh military dispute so that it can provide relevant medical services to a large number of patients including causalities.

Abstract: By making a mounting frame for a filter disposed at the front of the ceiling in a clean room of a sintered metallic material, the mounting frame obtains a structure with a strength capable of supporting the filter and with an air filtering resistance comparable to that of the filter, thereby preventing standing air in the lower part of the mounting frame and solving the problem of lowered purity of air.

Abstract: A unit for a clean room system of substantially inverted L-shaped cross section having a hollow ceiling, and a hollow wall communicating at the upper end thereof with the ceiling and at the lower end thereof with the floor in the room.= An air purifying filter is disposed at the front of the ceiling, and a cold water supplying conduit for an air conditioner control unit is located at the rear of the ceiling. A clean room system has a plurality of the units. Thus, the clean room can be simply and rapidly constructed without the necessity of a large space at the back side of a ceiling or under a floor to accommodate air conditioning ducts, thereby lowering the height of a building as compared to a conventional one, even if a 2-story or 3-story clean room is constructed. Further, the layout, such as a volume and shape in the room can be freely modified and uniform temperature and moisture can be maintained in the clean room.

Abstract: An air conditioner in which a drain pan disposed under a heat exchanger can completely collect and exhaust liquid such as condensed liquid or hot liquid and air intaken from an air intake port is passed through a ventilation passage, thereby completely air conditioning in the corners and the vicinity of a floor surface, the heat exchanger for preferably exchanging heat in a large capacity can be installed in a conditioner body and the size of the conditioner can be still constructed in small size. Thus, the air conditioner can completely condition the corners and the position near a floor surface in the room.
