“QMEMS” EPSON TOYOCOM

In order to meet customer needs in a rapidly advancing digital,

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.

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.

PROMOTION OF ENVIRONMENTAL MANAGEMENT SYSTEM

CONFORMING TO INTERNATIONAL STANDARDS

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.

At Epson Toyocom, all environmental initiatives operate under

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

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.

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/TS 16949 is a global standard based on QS-9000, a severe standard

corresponding to the requirements from the automobile industry.

QS-9000 is an enhanced standard for quality assurance systems

formulated by leading U.S. automobile manufacturers based on the

international ISO 9000 series.
