Abstract

1,064,763. Semi-conductor time delay circuits. COMPAGNIE DES COMPTEURS. Jan. 7, 1965 [Jan. 17, 1964], No. 721/65. Heading H3T. In a time delay circuit of the type in which a unijunction transistor is triggered after a delay imposed by a resistance/capacitance circuit, the initial voltage across the capacitance is clamped by a diode so as to provide uniform time periods.
