“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.
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.
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.

● In this new crystal master for Epson Toyocom, product codes and markings will remain as previously identified prior to the merger.
Due to the on-going strategy of gradual unification of part numbers, please review product codes and markings, as they will change during the
course of the coming months.
We apologize for the inconvenience, but we will eventually have a unified part numbering system for Epson Toyocom that will be user friendly.
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 la
y
er, and
g
lobal deforestation.
ISO/TS 16949 is a global standard based on QS-9001, a severe standard
corresponding to the requirements from the automobile industry.
