(66) is a volume for pulse adjustment. (62) is a control circuit consisting of a flip-flop circuit or the like that switches every pulse. The pulses generated by the above pulse generation circuit (61) and control circuit (62) are applied to the current amplification circuits (63) and (64), and the power supply (

Adjust the current of 4) with the volume control (67) to make a difference between the currents applied to the coils (41) and (42), giving a strong current to one coil (41) to obtain a strong magnetic force, and applying a strong current to the other coil (41). A weak current is applied to the coil (42) to obtain a weak magnetic force. In addition, the above coils (41) and (42)
This means double winding on one spool.

Therefore, the strong magnetic force generated by one coil (41) strongly repels the movable plate (2) and pushes it up above the one support shaft (3), and then the magnetic force of the coil (41) disappears. When the movable plate (2) begins to fall, the falling speed is adjusted by a weak magnetic force generated from the other coil (42), and the falling speed of the movable plate (2) is stopped midway by adjusting the strength of the magnetic force. [E] You can also make it so that you can read it. The above vertical movement can be repeated for each pulse, and the period can be adjusted by the pulse generation circuit (61) and the pulse generation circuit (67).

Since the container is moved up and down by the magnetic force of an electromagnet placed on the bottom surface of the container, there is no need to insert the support shaft that supports the movable plate from above the container as in conventional models. It can be installed inside the container and can be covered with a lid above the container to easily block outside air while stirring the liquid.
It prevents the intrusion of dust and dirt, and furthermore, the container can be completely sealed, allowing stable stirring not only for short periods of time but also for long periods of time. Since it does not use a mechanical drive mechanism like the conventional one, it has the effect of providing a stirring device that does not generate noise or heat.
