The DEC exhibited "Gas Chrom-8 Computer system for gas chromatography and IBM-Model 1800 and 1130. There were also exhibited other systems, among them smaller inexpensive computers. There were also shown slides on results of work with computers done by S. Sasaki H. Abe of Japan s Tohoku University and by T.

GC-MS. JEOl DX303 apparatus (Japan Electron Optic Laboratory) was used, the carrier gas being helium. The other GC conditions were the same as those just described, and an MS analysis of electron impact (El) at 70eV was conducted. 

A new chapter in the uses of semiconductors arrived with a theoretical paper by two physicists working at IBM s research laboratory in New York State, L. Esaki (a Japanese immigrant who has since returned to Japan) and R. Tsu (Esaki and Tsu 1970). They predicted that in a fine multilayer structure of two distinct semiconductors (or of a semiconductor and an insulator) tunnelling between quantum wells becomes important and a superlattice with minibands and mini (energy) gaps is formed. Three years later, Esaki and Tsu proved their concept experimentally. Another name used for such a superlattice is confined heterostructure . This concept was to prove so fruitful in the emerging field of optoelectronics (the merging of optics with electronics) that a Nobel Prize followed in due course. The central application of these superlattices eventually turned out to be a tunable laser.
