日本电气公司(NEC)为计算机系统开发了新一代的高速打印机,新型打印机是用压电原理工作的,与原有的打印机在性能方面相比,速度更快、噪音更小、精度更高、性能价格比更好。新型打印机的打印头,是由24个相同的、精度极高难以制作的零件组成。这些零件是用精冲技术生产的,由日本Atsugi的Feintool精冲工程公司专门研制,并与日本电气公司合作生产。日本电气公司(NEC)开发的这最新一代的NM5020高速打印机首次应用压电原理代替较通用的电磁式驱动系统。压电原理——已知晓多年——
NEC has developed a new generation of high-speed printers for computer systems. The new printers are based on the piezoelectric principle. Compared with the original printers, NEC has faster performance, lower noise and higher accuracy than the original printers. Performance and cost better. The new printer’s printhead consists of 24 identical parts that are extremely difficult to make. These parts are produced using fine blanking technology and have been specially developed by Feintool Seiko Engineering Co., Ltd. of Atsugi, Japan, in cooperation with Nippon Electric Corporation. The latest generation of NM5020 high-speed printers, developed by NEC, is the first to apply the piezoelectric principle instead of the more versatile electromagnetic drive system. Piezoelectric principle - known for many years -
