?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 ah ead 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 automoti ve 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 certif ication. 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 estab lishme nts i n japa n and abroad. we have also acquired iso/ts 16949 certification that is requested strongly by major automotive manufacturers as st andard. ? explanation of the mark that are using it for the catalog ? pb free. ? complies with eu rohs directive. *about the products without the pb-free mark. contains pb in products exempted by eu rohs directive. (contains pb in se aling glass, high me lting te mperature type solde r or othe r.) ? the products have been designed for high reliability applications such as automotive. notice this material is subject to change without notice. any part of this material may not be reproduced or duplicated in any form or any means without the written permission of epson to y o c o m . the information, applied circuitry, programming, usage, etc., written in this material is intended for reference only. epson to yocom does not assume any liability for the occurrence of infringing on any patent or copyright of a third party. this material does not autho rize the licensing for any patent or intellectual copyrights. any product described in this material may contain technology or the subject relating to strategic products under the control o f the foreign exchange and foreign trade law of japan and may require an export license from the ministry of international trade and industry or other approval from another government agency. ? ? ? ? you are requested not to use the products (and any technical information furnished, if any) for the development and/or manufact ure of weapon of mass destruction or for other military purposes. you are also requested that you would not make the products available to an y third party who may use the products for such prohibited purposes. these products are intended for general use in electronic equipment. when using them in specific applications that require extr emely 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 securit y 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 merg er. due to the on-going strategy of gradual unification of part numbers, please review product codes and markings, as they will cha nge 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. 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 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 iso/ts 16949 is a global standard based on qs-9000, a severe standard corresponding to the requirements from the automobile industry.
