THE CRYSTALMASTER
ENERGY SAVING EPSON
EPSON offers effective savings to its customers through
a wide range of electronic devices, such as semiconductors,
liquid crystal display (LCD) modules, and crystal devices.
These savings are achieved through a sophisticated melding
of three different efficiency technologies.
Power saving technology
provides low power con-
sumption at low voltages.
Energy Saving
Space saving technology
provides further reductions
in product size and weight
Power Saving
through super-precise pro-
cessing 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 repre-
sented in each of the products that we provide to our cus-
tomers.
In the industrial sector, leading priorities include mea-
sures to counter the greenhouse effect by reducing CO2,
measures to preserve the global environ-
ment, and the development of energy-
efficient products. Environmental
problems are of global concern, and
although the contribution of energy-
Resource
saving technology developed by
Saving
EPSON may appear insignificant,
we seek to contribute to the develop-
ment 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. QUARTZ DEVICE DIVISION acquired ISO9001 and ISO14001 certification
by B.V.Q. I. (Bureau Veritas Quality International) .
ISO9001 in October, 1992.
ISO14001 in November,1997.
