"standard": computers, office equipment, communications equipment, test and measurement equipment, audio and visual equipment, home electronic appliances, machine tools, personal electronic equipment and industrial robots "special": transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster systems, anti-crime systems, safety equipment and medical equipment (not specifically designed for life support) "specific": aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems and medical equipment for life support, etc. the quality grade of nec semiconductor products is "standard" unless otherwise expressly specified in nec's data sheets or data books, etc. if customers wish to use nec semiconductor products in applications not intended by nec, they must contact an nec sales representative in advance to determine nec's willingness to support a given application. (note) (1) "nec" as used in this statement means nec corporation, nec compound semiconductor devices, ltd. and also includes its majority-owned subsidiaries. (2) "nec semiconductor products" means any semiconductor product developed or manufactured by or for nec (as defined above).
