Corporation does assume liability infringement patents, copyrights other intellectual property rights third parties arising from device described herein other liability arising from such device. license, either express, implied otherwise, granted under patents, copyrights other intellectual property rights Corporation others. While Corporation been making continuous effort enhance reliability semiconductor devices, possibility defects cannot eliminated entirely. minimize risks damage injury persons property arising from defect semiconductor device, customer must incorporate sufficient safety measures design, such redundancy, fire-containment, anti-failure features. devices classified into following three quality grades: "Standard", "Special", "Specific". Specific quality grade applies only devices developed based customer designated "quality assurance program" specific application. recommended applications device depend quality grade, indicated below. Customers must check quality grade each device before using particular application. Standard: Computers, office equipment, communications equipment, test measurement equipment, audio visual equipment, home electronic appliances, machine tools, personal electronic equipment industrial robots Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster systems, anti-crime systems, safety equipment medical equipment (not specifically designed life support) Specific: Aircrafts, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems medical equipment life support, etc. quality grade devices "Standard" unless otherwise specified NEC's Data Sheets Data Books. customers intend devices applications other than those specified Standard quality grade, they should contact Sales Representative advance. Anti-radioactive design implemented this product.
