Abstract: An atomizer system has a first pressure accumulation tank 7 for storing high-pressure air generated by a compressor 6, to which a second pressure accumulation tank 28 is connected via an air tube 3, so that the second tank 28 is charged with the high pressure air. The tube 3 has a sealing valve 26 which is removably connected with the second tank 28. The tank 28 is connected to a regulator which may reduce the pressure of the air supplied from the second tank 28 to a predetermined low pressure level. With the second tank 28 disconnected from the first tank 6, the low-pressure air is provided to an atomizer 11 for atomization of medicine in inhalation treatment.

Abstract: A heat pump apparatus comprising: a heat pump circuit composed of an external combustion engine, a radiator through which a first medium heated by a first heat exchanger of said external combustion engine flows and a cooler through which a second medium cooled by a second heat exchanger of said external combustion engine flows; a motor for supplementing a motive power to said external combustion engine; a brake for braking said external combustion engine; a detector for detecting a heating load; and a controller for calculating a motive power necessary for said external combustion engine based on the difference between a value detected by said detector and a preset value previously set, and for controlling said motor to move when the calculated motive power is larger than a self-output of said external combustion engine.
