Abstract
This paper is concerned with a A-D converting circuit which consists of a detecting circuit using parametron and either electric conductors or ferromagnetic material arranged along the moving axis of a specified mechanical element. This A-D converting circuit can be used to convert mechanical quantities (displacement, position, rotating angle and so on) of the mechanical element into the digital signal using jumping phenomena of the oscillating phase of the parametron.
Two parametron circuits are added to increase the flexibility for the information processing of the digital signal converted through this A-D converting circuit. One of these circuits is an eliminating circuit of the internal noise of the parametron and the other is a discriminating circuit of the moving directions of the mechanical element. The operation of these circuits is achived by setting and resetting parametronized memorial circuits through detecting circuits using parametron.
From the experiments on this converting circuit, the following necessary conditions to stabilize the converting operation are clarified: the changing cycle of the reactance component in the sensing circuit must be larger than twice the keying cycle of the parametron and the changing ratio must be at least 0.1%.
