Eiichi Goto

[1][2] In 1954 while he was still a graduate student, Goto invented the parametron, a circuit element that combined a ferrite core with a capacitor to generate electrical oscillations whose timing could be controlled.

[8] In electron beam lithography, Goto's work included the development of double deflection tubes and variable shaping techniques.

[4] In the early 1970s, Goto's work on electron beam lithography led him to become interested in the ability of symbolic algebra systems to manipulate mathematical formulae.

[2][4] Other topics in Goto's research included the search for magnetic monopoles and fractional electrical charges, computer graphics, memory devices based on cathode ray tubes, arbitrary-precision arithmetic, and the automated analysis of bubble chamber experiments.

[9] He won the Okochi memorial Technology Prize [ja] in 1988, and in 1989 he was given the Purple Ribbon Medal of Honor by the Japanese government for his work on electron beam shaping.
