摘要： PURPOSE:To improve comfortableness in an air showering room and to further improve dust removing effect of dusts adhered to a human body and clothing. CONSTITUTION:When a person rises on a footstool 70 and a detecting sensor detects the person, a controller 74 operates an air injecting high-speed fan 52 and closes a supply air damper 60 and an exhaust damper to shut OFF a supply air duct 58 and an exhaust duct 64. Thus, clean air is injected from a jet nozzle 44 into an air showering room 22 while circulating the air of the room 22 by the fan 52, thereby removing dusts adhered to a human body and clothing. When the sensor does not detect a person, the controller 74 stops the fan 52, and opens the damper 60 and the exhaust damper. Thus, a flow of air conditioned air for cooling to pass through the room 22 at a high temperature by heat generated particularly from a motor of the fan 52 during using of the room is formed to exhaust the heat of the room 2.

摘要： PURPOSE:To provide the separator capable of exerting a peeling power on the surface of a filter plate to keep the contaminant removability and capable of remarkably reducing the load stress generated in the filter plate. CONSTITUTION:A rod-shaped baffle 26 is freely movably fixed in a clearance between filter plates 18 in the axial direction of a rotating shaft 22. Accordingly, a velocity gradient is generated to exert a shearing force on the surface of the filter plate 18, and the contaminant is released from the filter plate 18. Further, the baffle 26 is moved to a position where the pressures on both sides are equalized by a fluid resistance, and hence the load stress generated in the filter plate 18 is reduced.

摘要： PURPOSE:To provide a rotary type membrane separator capable of reducing consumption of electric power consumed by a driving motor for rotating a filter plate in the case of performing concentrating treatment. CONSTITUTION:A plurality of filter plates 34 for performing concentration are provided in the inside of a closed vessel 16 for performing concentrating treatment. The surfaces of these filter plates 34 are covered with a filter membrane 46 for passing the substance except the concentrated component. The substance except the concentrated component is passed through a hollow part 40 from the filter membrane 46 and sent to a water tank 74 from a discharge port 38. Concentrate 92 is passed through a pipe 24 from an outlet port 22 and sent to a necessary part such as a water tank 90. Further the temperature of concentrate 92 in the closed vessel 16 is detected by a resistance thermometer bulb 60. The viscosity state of the concentrate 92 is grasped by this temperature. The number of revolutions of a driving motor 54 for rotating the filter plates 34 is reduced by a rotation controlling device 62. Thereby consumption of electric power consumed by the driving motor 54 is reduced.

摘要： PURPOSE:To cool beer in a barrel container uniformly as a whole by a method wherein a piston pump extending toward a bottom of the container is arranged at a mouth piece of the barrel container, and the piston is driven by a spring made of a shape memory alloy which is deformable corresponding to the temperature of the beer in a bottom layer. CONSTITUTION:A beer barrel container 10 is housed in a cooler (not shown) and beer 30 is cooled through a barrel bottom 16. At this time, the beer 30 is low in the heat transmission, and therefore, a bottom layer of beer 30 is more cooled along the barrel bottom 16. Thus a temperature gradient occurs. In order to overcome this, when a cooling temperature of the bottom layer beer 30 reaches a prescribed value, a spring made of a shape memory alloy (not shown) is shrunk and deformed. Hence, a piston 40 of a piston pump 31 connected to the spring is lowered, so that the beer in a pipe 32 provided below the piston 40 is discharged out of an opening 36 along the barrel bottom 16. Thus, the beer 30 is circulated in convection current by this pumping and cooled uniformly as a whole.
