Abstract
946,777. Digital electric calculating apparatus. NIPPON ELECTRIC CO. Ltd. Aug. 22,1960 [Aug. 20, 1959], No. 28995/60. Heading G4A. In an output operation a register normally used for other purposes is put into a loop circuit through which the output word is passed, transmission to output equipment being effected simultaneously and the end of the word being indicated without the insertion of an additional signal. A word to be transmitted is stored in memory MEM, an input/output register I/O R is cleared and a counter M/Q count normally used for storing a multiplier or quotient is put into the loop. Excess-3 code is used but 0000 indicates S or the end of a word. Initially therefore the register I/O R stores S. As each digit is sent from I/O R to M/Q count it is also sent to input/output equipment I/O M. Therefore when the signal S completes a circuit it indicates the end of a word.
