NDK晶振品牌全新英文版公司介紹書
  Satellites take humankind’s dreams into space. Those satellites contain devices made at NDK. Devices used in satellites face extremely harsh conditions from shocks and vibrations during launch, to severe thermal uctuations, and the like. We will continue to deliver products that reliably perform even in such harsh operating environments. Indeed, we are the only Japanese crystal unit manufacturer approved for use by JAXA, the Japan Aerospace Exploration Agency.
  Autobraking systems that detect danger and auto-steering systems that prevent cars from straying out of their lanes are just two examples of new applications for our crystal devices in advanced driver assistance systems (ADASs). Our components keep you safe by always transmitting accurate frequencies even amid severe shocks,vibration, and harsh temperature uctuations.
  From controlling household appliances to tracking product inventory, from feeding pets to watering plants, the Internet of Things (IoT) offers consumers various solutions. This, too, is supported by NDK technology. Our crystal devices ensure precise synchronization and stable communication between these “things” by providing each of them with a basic frequency.
Creating a Crystal-Powered Future from Inside
  In 1964, after eight long years of trial and error in a quest to unlock the true potential of crystal, NDK successfully mass-produced synthetic crystal with a much higher purity than natural crystal. For more than half a century since then, our world-leading crystal technologies have helped electronics develop from inside the devices.
  The ongoing evolution of electronics solutions helps make the world safer, more secure, and more comfortable—and that evolution is made possible by crystal devices. At NDK, our quest is to leverage our strengths as a comprehensive maker of frequency solutions to uncover the future with crystal.
 
NDK Will Continue to Support Future Development from Inside the Devices
  ■ Crystal is “Salt for Electronics”
  At NDK, we make crystal devices for the control, selection, and detection of frequencies. Electronic devices work in frequencies as they generate electronic waves, which make crystals a vitally important component. Crystals have been called “salt for electronics”—the basic element that upholds the modern, information-based society. Without crystal, our living standards would be set back by around a hundred years.
  ■ The Founding Philosophy at Our Core
  NDK was founded in 1948 as a vehicle for contributing to the prosperity of society and world peace through our service to customers. That philosophy is founded on a belief that providing reliable, high-quality, attractive products at an appropriate price can be useful to customers and can, by extension, help society prosper. Moreover, the founder believed that enhancing communication among people through accurate information would promote international understanding as a cornerstone of lasting peace. This belief was generated by the founder, Masamichi Takeuchi, from his experiences of the war. Today, we apply this founding philosophy in every facet of our business, and hold an annual commemorative event where all employees gather to share and reafrm our devotion to this founding philosophy.
  Throughout NDK’s history, we have endeavored not only to amass skills and technologies, but also to earn customers’trust. To that end, our manufacturing practices are built on the “three Gs”—genba, genbutsu, and genjitsu—go and see, get the facts, grasp the situation, the fundamentals of manufacturing. In that way, we can establish solid reliability by upholding a level of quality that ensures our products work accurately in all environments. Moreover, we frequently visit our customers so as to anticipate their needs and propose the ideal products. In this way, manufacturing, sales, and engineering divisions are able to work as a cohesive unit to meet a diverse range of needs, and to innovate and stay abreast of society’s ever-changing demands.
  Elsewhere, we are actively involved in the creation of international standards for electronic components as a member of the International Electrotechnical Commission’s technical committee on piezoelectric devices. In that capacity, we contribute to the establishment of Japan-led global standards, the expansion of the crystal market, and a larger market share for Japanese products. Also, we were the rst Japanese company to adopt International Financial Reporting Standards (IFRS). Our involvement in international standard activities and our adoption of IFRS is an illustration of our desire to stay ahead of trends and cement our status as a trusted global partner.
■ Our Vision for NDK in the Future
  NDK expects that mobile phone base stations, the infrastructure for 5G wireless communications systems (next-generation high-speed communication standard), will go into full-scale operations from scal 2021. It means that NDK is on the verge of a huge business chance. With 5G systems taking off, applications for quartz crystal devices will surge, from 5G smartphone terminals to IoT, including for automated driving. The advent of 5G will spur demand for high-accuracy crystal device products capable of high frequency with low-phase noise features greater than what is currently available.
  NDK is working to provide the high-accuracy products which are required in the 5G era and with a capital investment into autoclaves NDK has commenced manufacture of high-quality synthetic quartz crystals vastly different from previous products. NDK is also moving away from our standard machining techniques and expanding manufacturing using photolithography processing, which incorporates semiconductormanufacturing technology.
  Through the integration of production, from high-quality synthetic quartz crystals to quartz crystal oscillator products, NDK will continue to contribute to the creation of societies that are safe, secure, and comfortable.
  Crystal devices are an indispensable part in the operation of all kinds of electronic equipment. We continually seek technical innovation to drive the evolution of mobile phones, home appliances, computers, cars and the like.
■ Developing Compact, Highly Precise Products
  As electronic equipment has become smaller and more highly functional, there has been a need for crystal devices to do the same. Generally, reducing the size of crystal devices raises the risk of deterioration in temperature and aging properties, but we seek to circumvent those risks with our advanced technologies in areas like internal temperature control, frequency control, and precise mechanism design simulation. In this way, our development focuses on products that can anticipate and meet the latest needs.For instance, in 1998 we became the rst to develop a single-chip integrated circuit for temperature-compensated crystal oscillators, which provided huge impetus to accelerate the development of smaller, more precise crystal oscillators, a key component in mobile phone evolution. Following this, one client asked us to develop an oscillator 0.1 millimeters lower than the current size within two months. In electronics, 0.1 millimeters is a considerable reduction, and this meant developing from scratch. We began with the existing elemental technologies built up by our core technical departments, and enlisted the help of those involved with production technology and prototyping. The team came up with a cohesive plan to make the integrated circuit and ceramic package slimmer and to revise the sealing method. Finally, they were able to meet the client’s demands.
  Moreover, increased data volumes and faster speeds in telecommunications have given rise to greater demand for more connective infrastructures. Here, too, the result is a need for even smaller sizes and higher precision. We endeavored to make smaller devices with stable frequency by developing a unique signal processing technology (twin technology) that focuses on the difference in oscillation frequency from using two orders, which resulted in a world-beating level of precision.
■ Technical Prowess Leads to Development of New
  Next-Generation ProductsIn recent years, we have put our hard-won technical strengths to use in the development of sensors. More than 50 years’ experience in ultrasonic probes, as well as the development of inuenza test kits, allergen tests, and people-sensors for bathroom and toilet applications, have all come in handy for our efforts to make inroads into new markets such as healthcare and food. We will continue to anticipate next-generation needs and move forward with R&D that creates the kind of products that can contribute to a safer, more secure, more comfortable society.
  High reliability earned through uncompromising quality control
■ Pure Craftsmanship
  For crystal devices, high reliability refers to the ability to deliver the specied properties even in extreme uctuations of temperature, humidity, vibration, impact, or other environmental factors. Those properties must also be sustained over the long term. Our ability to provide this level of reliability is based on the uncompromising quality control that denes our manufacturing practices.
■ The NDK Quality Control Structure
  Our quality control is based on the “three Gs” policy—go and see, get the facts, grasp the situation— which ensures quality is constantly an integral part of the production process. We also pursue a Zero Defects program, which has contributed to our ability to provide reliable products for many years. Moreover, we were one of the early adopters of global standards for quality control, environmental control,and medical management systems,such as ISO 9001, ISO/TS 16949, ISO 14001, and ISO 13485.By maintaining such a stringent quality control structure, our products have earned the trust of organizations that demand impeccable reliability, including JAXA, which uses crystal units for space exploration.
 
Leading the march toward sustainability
  ■ Environmental Policies and Initiatives
  As a global enterprise, the NDK Group’s corporate philosophy includes the stipulation that we will “strive to conserve the earth’s environment and carry out our social responsibilities,” and we are actively promoting activities to aid this effort. Under our group-wide environmental protection framework (see Fig. 1), we work proactively to build, maintain, and improve an environmental management system.
  ■ Environmentally-Considerate Product Development
  Aiming to reduce our environmental impact, we have identied detailed challenges and solutions as part of a medium-term plan. Under this, we are working to prevent global warming, reduce waste, manage chemical substances, and prevent air and water pollution. In order to satisfy society’s demands regarding environmental protection, including, among other things, reducing carbon dioxide emissions, we have introduced Green Crystal Technology™ (see Fig. 2) as part of our unique crystal device development concept. To that end, we use state-of-the-art technology as a means of promoting the development of smaller, lighter, more energy-efcient products and pursuing more comprehensive energy efciency and environmental performance over each product’s lifecycle.
  As a result, we have achieved our goal of reducing carbon dioxide emissions by six percent, and we intend to increase that number in future. We were valued as a highly eco-friendly corporation by the Development Bank of Japan and earned an eco-friendly rating.
