A medicine supply apparatus which comprises, in a case accommodating section 8, a plurality of tablet cases 3 for accommodating medicine and charges or supplies medicine into a bag 72, which medicine has been discharged from each tablet case 3 based on a prescription. A compiler reallocates spilled variables from stack memory to other available registers. Moreover, to provide long life despite a small battery, the microprocessor is run in a standby mode in which the microprocessor draws little power unless it actually samples the state of the sensor switch during select intervals. The electrode pads are connected to electrode pads on a mount frame by solder wiring layers arranged on an insulating film covering the side wall of the multi-layer structure. The friction rim surfaces are in mutual contact with each other and thereby enabled to transmit a friction-based torque between each other. The invention applies to a device for fueling a rocket engine that includes at least two pumps, each driven by the device of the invention, and means for controlling the internal combustion engines for driving the pumps, adapted for independently varying the operating parameters of these engines so as to independently adjust the rotation speeds of the pumps.
