These savings are achieved through a sophisticated melding of three different efficiency technologies. Power saving technology provides low power consumption at low voltages. Energy Saving Space saving technology provides further reductions in product size and weight Power Saving through super-precise processing and high-density assembly technology. Space Saving Time saving technology shortens the time required for design and development Time Saving on the customer side and shortens delivery times. Our concept of Energy Saving technology conserves resources by blending the essence of these three efficiency technologies. The essence of these technologies is represented in each of the products that we provide to our customers. In the industrial sector, leading priorities include measures to counter the greenhouse effect by reducing CO2, measures to preserve the global environment, and the development of energyefficient products. Environmental problems are of global concern, and although the contribution of energyResource saving technology developed by Saving EPSON may appear insignificant, we seek to contribute to the development of energy-saving products by our customers through the utilization of our electronic devices. EPSON is committed to the conservation of energy, both for the sake of people and of the planet on which we live. SEIKO EPSON CORP.
