Electron beam type computer output on microfilm printer

摘要: An electron beam type computer output on microfilm printer employing an writing apparatus having evacuated housing closed by a Lenard window fabricated from differentially etched bulk supporting member through which the is directed for permitting egress out of into higher pressure ambient atmosphere surrounding with minimum scattering while maintaining integrity space within housing. The thin portion consists material different than and not susceptible to etchant employed form in bulky may be formed chemical reaction class materials consisting SiSiO2; Al-Al2O3; Ta-TaO; Ti-TiO; Si-SiC; Si-SiN; Al2O3 Si; like. SiO2, Al2O3, TaO, TiO, etc layer preferably first desired thickness surface elongated then being does react layer. further includes sensitive recording medium transport means immediately adjacent apparatus. Printer control circuit are coupled controlling operation thereof. A character generator supplied buffer memory unit controlled controls deflection blanking Use allows EBeam COM easily interfaced any system as standard plug compatible peripheral equipment.
