摘要： A power source device for a bubble memory unit, wherein there is supplied a first DC voltage E.sub.c which is applied to control circuitry for controlling the reading and writing of data, a second DC voltage signal E.sub.d which is applied to drive circuitry for driving a bubble memory element, and a memory signal M.sub.e which enables data to be written in or read from the bubble memory element, the signals E.sub.c, E.sub.d and M.sub.e being made to rise and fall according to a prescribed sequence as a commercial power supply is connected and disconnected. The power source device includes first and second DC power source circuits, a comparator circuit for comparing the magnitude of the first DC voltage E.sub.c with a reference level V.sub.M having a value greater than an allowable lower limit value, and a delay circuit. The second DC power source circuit is actuated following a prescribed time delay which begins when the value of signal E.sub.c surpasses the reference level V.sub.M at the time that the commercial power supply is connected, and the memory enable signal M.sub.e is produced after the second DC power source circuit has been actuated. The memory enable signal M.sub.e is made to vanish when the magnitude of signal E.sub.c drops below the reference potential V.sub.m at the time that the commercial power supply is disconnected, the second DC power source circuit being rendered non-operational following a prescribed time delay.

摘要： In a power source device for a bubble memory unit consisting of a bubble memory part and a control part, a controlling supply voltage to be applied to both the bubble memory part and the control part is produced by a power source circuit based on a pulse width modulation system. The power source circuit is provided with a circuit which can expand the signal pulse width in excess of its upper-limit value during the ordinary voltage control. When the controlling supply voltage has become lower than a predetermined value, the pulse width is expanded so that the refresh operation may be perfectly executed when the power source device for the bubble memory unit is turned off.
