Abstract: A current controller for generating a control signal which controls supply current flowing from a power source to a load includes an interface circuit which sets a threshold based on an instruction from an outside of the current controller, a threshold setting circuit which stores and outputs the threshold, a sensing circuit which determines a current or a temperature of a sensing element, and outputs a signal indicating that the supply current should be interrupted as the control signal if a determined current or a determined temperature exceeds the threshold, and a sensing control circuit which generates a clock signal including pulses with a predetermined period. The sensing circuit determines the current or the temperature of the sensing element during an active period of the clock signal.

Abstract: A safety indwelling syringe has a hollow needle to be inserted into the body of a patient, a fixed sheath fixing the hollow needle and covering the needle partly, and a protective sheath slidably fitted to the fixed sheath. The hollow needle is exposed when used. After use, the protective sheath is pulled out toward the tip of the hollow needle so as to cover the needle entirely.
