Abstract

PURPOSE: To increase the effective temperature range for the bubble device by controlling the current to be flowed to the bubble generator within the upper and lower limit to the chip temperature via the output of the temperature detector which detects the chip temperature.
CONSTITUTION: In the magnetic bubble device incorporating new creation type bubble generator 2, the serial circuit of resistance 6 and posistor 5 to actuate the temperature detector which detects the temperature of chip 1 is provided along with switching element 7 which controls the current to be supplied to generator 2 from power source 3 via the detection output of the temperature detector. In another example of the device, temperature detector 15 is provided separately to be inserted to resistance 9 and 10 which are connected in series to generator 2 plus switching element 12 which is turned on and off by the output of detector 15. Thus, the effective temperature range can be increased for the bubble device.
