A washing machine installed with a brushless motor for driving an agitator and an inner tub includes a storage device storing a data table representative of a plurality of preselected rotational speed values and values of voltage applied to the brushless motor driven at each preselected speed with respect to every different load applied to the brushless motor, a load amount determining device, a control device determining the voltage applied to the motor based on the data table when one preselected speed is selected with an operating switch. An amount of load is determined when one preselected speed is selected. A suitable value of applied voltage is selected which value has a predetermined relation to the preselected speed selected in the condition of the determined amount of load. The amount of load is determined by collating the load amount and the number of revolution with the data table.

This invention relates to a digital sound data storing device wherein analog sound data is synthesized from digital sound data. The device includes a case and an IC card detachably attached to the case. A plurality of digitized sound data groups are stored at a built-in memory of the IC card. The digitized sound data groups are obtained by recording sentences for foreign language conversation practice through a microphone to thereby obtain analog sound signal which is converted to digital sound signal. When the IC card is attached to the case, a signal processing circuit operates to read out the digital sound data group, which is converted to the analog sound signal. The analog sound signal is supplied to an amplifying circuit and reproduced as sound.
