The invention provides a load detecting system comprising a core () of magnetostrictive material, a coil () disposed in the vicinity of the core, and a load detecting circuit () connected to the coil () for detecting the magnitude of a load acting on the core (). The load detecting circuit () comprises an exciting circuit () for passing an a.c. detecting current through the coil (), a pulse current generating circuit () for passing through the coil a detection preparing current having a current value greater than the maximum value of the detecting current, a change-over circuit () for effecting a change-over between the exciting circuit () and the pulse current generating circuit () to pass the detecting current through the coil after passing the detection preparing current therethrough, and a microcomputer () for deriving the magnitude of the load acting on the magnetostrictive element based on an impedance variation produced in the coil during the period of passage of the detecting current through the coil.

Load detecting system and automatic washing machine equipped with the system

A water treating device includes a water container for containing water; an electrolyzing chamber for sterilizing water; a water treatment line which couples the electrolyzing chamber with the water container; a sensor for measuring residual chlorine concentration; and a device for controlling the amount of the water to be electrochemically decomposed in the electrolyzing chamber on the basis of the residual chlorine concentration measured by the sensor to keep the residual chlorine concentration of the water to be fed back into the water container within a predetermined range. A bypass line is provided which is branched from the water treatment line upstream of the electrolyzing chamber for sampling the water, introducing the sampled water into the sensor for the measurement of the residual chlorine concentration thereof, and discharging the sampled water into the electrolyzing chamber after the measurement.
