“QMEMS” EPSON TOYOCOM
In order to meet customer needs in a rapidly advancing digital,
broadband and ubiquitous society, we are committed to offering products
that are one step ahead of the market and a rank above the rest in quality.
To achieve our goals, we follow a “3D (three device) strategy” designed to
drive both horizontal and vertical growth. We will to grow our three device
categories of “Timing Devices”, ”Sensing Devices” and “Optical Devices”,
and expand vertical growth through a combination of products from these
categories.
A Quartz MEMS is any high added value quartz device that exploits the
characteristics of quartz crystal material but that is produced using MEMS
(micro-electro-mechanical system) processing technology.
Market needs are advancing faster than previously imagined toward
smaller, more stable crystal products, but we will stay ahead of the curve
by rolling out products that exceed market speed and quality
requirements. We want to further accelerate the 3D strategy by QMEMS.
Quartz devices 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 “Digital Convergence” solutions to problems
arising with products for consumer use, such as, core network systems
and automotive systems.
QMEMS and its logos are registered trademarks or trademarks of Seiko
Epson Corporation in Japan and other countries.
PROMOTION OF ENVIRONMENTAL MANAGEMENT SYSTEM
CONFORMING TO INTERNATIONAL STANDARDS
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.
All of our major manufacturing and non-manufacturing sites,in Japan
and overseas, completed the acquisition of ISO 14001 certification.
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
In order provide high quality and reliable products and services than
meet customer needs,
Epson Toyocom made early efforts towards obtaining ISO9000 series
certification and has acquired ISO9001 for all business establishments in
Japan and abroad. We have also acquired ISO/TS 16949 certification
that is requested strongly by major automotive manufacturers as
standard.
ISO/TS16949 is the international standard that added the sector-specific
supplemental requirements for automotive industry based on ISO9001.
