Abstract
Recently, the rectangular hysteresis magnetic material has been adopted as the computer memory, but the principle of this device is based on the characteristics of binary counter corresponding to two saturated flux levels.
As a unique application of the memory core, the analog memory element and decimal counter have been developed by using the rectangular hysteresis magnetic material. This material has been already applied to the reliable and compact decimal counter. The authors constructed for the input decoding stage of digital computer a magnetic memory device having A-D convertible function which constantly generates pulses from zero to nine to the input analog voltage. In this device the digitalized information is alternatively memorized by two magnetic cores. S-N ratio is improved by exchanging the information between two cores and the information is stored as the decimal signal.
