Abstract: PURPOSE:To reduce the withstand current amount of a driving switching element by slightly shortening the length of a pulse applied to a stator winding of the semiconductor motor at the end, thereby providing a timing interval for switching the current to the next phase winding and thereby preventing the peak current produced at the winding. CONSTITUTION:A record counter 11 starts counting upon receipt of a voltage E1, a ring counter 12 is operated by the output pulse of the terminal (1), the output pulse of the ring counter 12 is switched to the next phase at every counting cycle, for example, from the output (a) to the output (b). If a pulse is produced at the terminal (8) or (9), it is applied through an OR gate 19 to AND gates 28, 35, and the output of the gate 35 becomes 1. A transistor 37 is conducted with the 1 output, and no voltage E2 is applied to the comparator circuit 40. Accordingly, both the outputs of the circuit 40 and the gate 20 become 0. Thus, the transistor 5 is turned OFF, and the current i1 to the winding 1 is intercepted.

Abstract: PURPOSE:To start cooking at a time set by a desired cooking output by one key operation by starting a cooking operation by a cooking mechanism and cooking by a cooking output corresponding to a set cooking time when a state having no operation signal reaches a predetermined time. CONSTITUTION:When a strong cooking output select key 7 is, for example, pressed in the case of cooking, an output is set, a display unit 3 is displayed to be strong, and as its pressed state is continued, a set cooking time is added and displayed. If a finger is separated from the key 7 when it becomes a desired set cooking time, a magnetron 2 is driven after its three seconds, and cooking is started. Then, if other cooking output select key 7 is pressed before the three seconds are elapsed, already set content is reset, it is switched to a set cooking time of new cooking output. When a subtraction key 9 is pressed, already set cooking time is subtracted, and cooking is started after the operation is finished.

Abstract: PURPOSE:To eliminate the fluctuation of the output terminal voltage at the control voltage switching time, i.e., the impulse noise by providing the switch circuit which selects only one of the output of the two input ampliying steps and applies the selected output to the output amplifier of the next step. CONSTITUTION:The difference exists in that the switch circuit consisting of transistors Tr36-39 plus constant voltage cource 27 is provided between the two output terminlas (collector terminals) of two input step emitter-earthed amplifiers 10 and 11 and the input terminal (base terminal) of output amplifier 12 in order to apply selectively only one of the output signals of amplifier 10 and 11 to the input terminal of amplifier 12. Even though the output of amplifiers 10 and 11 are switched via the above mentioned switch and with use of the control voltage of control terminal 4, the equal output DC voltage is obtained for output terminal 3 by setting resistance 23 and 24 plus 19 and 21 equal to each other and owing to the fact that the base terminals of Tr10 and 11 are biased by common voltage source 28 via resistance 15 and 16. So is for the amplifier by the control voltage at the side non-selected, thus eliminating the voltage fluctuation at the swithcing time.
