(Equivalent to 1 minute of monthly deviation) 3D STRATEGY EPSON TOYOCOM In order to meet customer needs in a rapidly advancing digital, Quartz devices have become crucial in the network environment broadband and ubiquitous society, we are committed to offering where products are increasingly intended for broadband, products that are one step ahead of the market and a rank above ubiquitous applications and where various types of terminals can the rest in quality. To achieve our goals, we follow a 3D (three transfer information almost immediately via LAN and WAN on a device) strategy designed to drive both horizontal and vertical global scale. Epson Toyocom Corporation addresses every single growth. We will to grow our three device categories of Timing aspect within a network environment. The new corporation offers Devices, Sensing Devices and Optical Devices, and expand Digital Convergence solutions to problems arising with products vertical growth through a combination of products from these for consumer use, such as, core network systems and automotive categories. 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. In the future, new group companies will be expected to acquire the certification around the third year of operations. 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 Epson Toyocom quickly began working to acquire company-wide ISO 9000 series certification, and has acquired ISO 9001 or ISO 9002 certification for all targeted products manufactured in Japanese and overseas plants. Epson Toyocom has acquired QS-9000 certification, which is of a higher level. Also, TS 16949 certification, which is also of a higher level, has been acquired. QS-9000 is an enhanced standard for quality ISO/TS 16949 is a global standard based on assurance systems formulated by leading QS-9000, a severe standard corresponding to U.S.automobile manufacturers based on the requirements from the automobile industry. the international ISO 9000 series.
