“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.  
Explanation of the mark that are using it for the catalog  
Pb free.  
Complies with EU RoHS directive.  
Pb free terminal designed. Contains Pb in products exempted by RoHS directive.  
(Contains Pb in sealing glass, high melting temperature type solder or other.)  
Complies with EU RoHS directive.  
The products have been designed for high reliability applications such as Automotive.

These products are intended for general use in electronic equipment. When using them in specific applications that require extremely high  
reliability, such as the applications stated below, you must obtain permission from Epson Toyocom in advance.  
/ Space equipment (artificial satellites, rockets, etc.) / Transportation vehicles and related (automobiles, aircraft, trains, vessels, etc.)  
/ Medical instruments to sustain life / Submarine transmitters / Power stations and related / Fire work equipment and security equipment  
/ traffic control equipment / and others requiring equivalent reliability.  
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.
