End to End EPSON TOYOCOM
The development of our ubiquitous network society has caused
a diversification of applications and has increased the demand for
high-level quartz devices in terms of quality, quantity, and
function.
The Quartz Device Operations Division of SEIKO EPSON
CORPORATION (EPSON)and TOYO COMMUNICATION
EQUIPMENT CO.,LTD.(TOYOCOM) were integrated on October
1,2005 to establish a new company, EPSON TOYOCOM
CORPORATION, to meet these market and customer demands.
Each company contributes its own strength; EPSON holds a
strong presence in consumer products and TOYOCOM is strong
in industrial products. The consolidation of these two companies
in a new company that provides advanced expertise with a wide
range of products for terminals and infrastructure to our
customers.
Quartz device have become crucial in the network environment
where products are increasingly intended for broadband,
ubiquitous applications and where various types of terminals can
transfer information almost immediately via LAN and WAN on a
global scale. EPSON TOYOCOM CORPORATION addresses
every single aspect within a network environment. The new
corporation offers “end-to-end” solutions to problems arising with
products for consumer use, such as core network systems and
automotive systems.
PROMOTION OF ENVIRONMENTAL MANAGEMENT SYSTEM
CONFORMING INTERNATIONAL STANDARD
At EPSON TOYOCOM, all environmental initiatives operate under the Plan-Do-Check-Action(PDCA) cycle designed to achieve continuous
improvements. The environmental management system (EMS) operates under the ISO 14001 environmental management standard.
In May 2001, all of our major manufacturing and non-manufacturing sites, in Japan and overseas, completed the acquisition of ISO 14001 certification.
In the future, new group companies will be expected to acquire the certification around the third year of operations.
ISO 14000 is an international standard for environmental
management that was established by the International
Standards Organization in 1996 against the background
of growing concern regarding global warming, destruction
of the ozone layer, and global deforestation.
WORKING FOR HIGH QUALITY
EPSON TOYOCOM quickly began working to aquire company-wide ISO 9000 series certification, and has acquired ISO 9001 or ISO 9002 certification
with all targeted products manufactured in Japanese and overseas plants.
The Quartz Device Operations Division (Ina Japan,EPM and SZE) have acquired QS-9000 certification, which are of higher Level.
Also QS-9000 and TS 16949 certification, which is of higher level, has been acquired.
QS-9000 is an enhanced standard for quality
assurance systems formulated by leading
U.S.automobile manufacturers based on
the international ISO 9000 series.
ISO/TS 16949 is a global standard based on
QS-9000, a severe standard corresponding to
the requirements from automobile industry.
