By A. W. HASLETT
Year by year, the makers of radio and electronic components--the raw material of radio and television sets, communications receivers, and calculating machines—sell more and more of equipment which, on the average, is smaller and more precisely made. At the same time, it is more tolerant of heat, cold, damp, and tough treatment.
Both trends were illustrated in the 14th exhibition of British radio and electronic components held recently in London. Output has increased six-fold in ten years. The number of exhibitors grows year
by year. But while 80-called conventional components are tinually improved and remain quantitatively important-u search for what is new the exhibition is a search, in the main, for the very small,
