The first TOYOTA sewing machine was built under the strict supervision of Kiichiro Toyoda himself, the founder of TOYOTA Motor Corporation. Kiichiro Toyoda had a strong belief that home-use products must be "functional" but yet "beautiful" at the same time. The first TOYOTA sewing machine HA-1 type was so highly evaluated that it was allowed to use the same TOYOTA trademark as the TOYOTA automobiles. Since then, TOYOTA sewing machine has continued to progress under the company mottoes of "Quality Supremacy", "User Friendliness" and "Elegant Appearance" with a strong emphasis on "Environmental Awareness".
AisinGasHeatPump operates on clean burning gaseous fuel (such as natural and propane gas), and uses the new 100% non-ozone-depleting refrigerant, R410A. Combining Heat Pump to Efficient Primal Energy (Gas), Aisin Gas Heat Pump has achieved high Energy Efficiency.
Aisin Gas Engine Cogeneration System produces electricity and sanitary hot water simultaneously by using a gas engine and generator. This system is connectable directly to the main electricity supply line through an inverter, thus achieving a high operating load factor.
