going forward, importance of "energy saving and resource saving"and"safety and security"should be established as the common wisdom. TheADS [Aqua Drive System: The New Water Hydraulics Technology], whichADS
uses"tap water"as the working fluid, is the innovation to meet thesetechnology
challenges.

forces. With its higher density structure, the ADS has advantages overthe electric drive in that it is not restricted by the standards for theprevention of water, drip or explosion. It excels in saving energy and controllability, is free from oil leakage
and not bound by the fire laws. Thus, the ADS is a superb new technology in the future society with its
extremely high environmental-friendliness and the use of water as the working fluid allowing its multiple
and effective use, against the backdrop of water shortage expected in the near future.		

Major application examples and expected fields of application
River and coastal operating devices
Prevention of environmental pollution on-site at
the worksites, such as water gates, navigation
lock, tide embankments, coastal landfill and soil
improvement, and ensuring safety in the worksite including prevention of electric leakage of thedevice.
Medical product and pharmaceuticalmanufacturing process
Manufacturing process of rehabilitation-purpose
bathing equipment and medicines.
Cosmetics production process
As powder and fluid are used as base materials,
sanitary and easy-to-clean, as well as explosionproof environment is needed. Molding processesof containers may also be involved.
Disaster prevention and rescue devices
Prevention of environmental pollution on-site at
the worksites, such as water gates, navigation
lock, tide embankments, coastal landfill and soil
improvement, and ensuring safety in the worksite including prevention of electric leakage of thedevice.
Household equipment
Operation of household equipment for theelderly/handicapped, such as household
elevators.
Precision molding process with cleanness
measures
Semiconductor press, medical devices-related
molding, and electronic device-related molding
processes.

Marine and underwater driven machinery
Undersea/underwater work machines for thework such as treatment of lake bed sediments.

Paper manufacturing process
Cleaning of rolls and dehydrating press, etc. in
the paper manufacturing process in the hightemperature/high humidity environment.
Seawater desalination and purification
process
Seawater desalination devices and water
purification processes to address anticipatedwater shortage.
Conveyance and packaging process
Addresses various beverage production factories
and bottling processes. Involves high degree ofsafety and sanitary requirements, e.g. for theconveyance and packaging of high-temperature
foods including retort food.
Food processing machinery
Must be sanitary and the whole machines should
be washable. Electric standards, such as theone related to waterproof, drip proof and electricleakage, are not applicable.
Nuclear power generation process
Work at sites with anti-radiation measures,
e.g. storage of radioactive waste and nuclear
fuel rods, reactor core inspection, anddecommissioning of reactors.
Semiconductor process
Operation of oil-free and clean-room readymachines and eqipment.
Nursing-care equipment
Safe and sanitary environment is needed. Often
operated in a wet place, e.g. rehabilitationequipment (bathtubs) and lifters in a bathroom.
Measures against electric leakage are not needed.
