移 “動する。Function> The movable part exhibits constant polarity, S at one end and N at the other end. If both coils are energized so that the sides facing each other are the same, for example N pole, the fixed iron core will also be magnetized in the same way, so the movable part will be either at the end that is the S pole or at the end that receives the attractive force and is the N pole. moves to one side due to the repulsive force. Also, if you change the current direction so that the opposite sides of the coil are both S poles,
The movable part moves in the opposite direction to the above due to the attraction and repulsion forces.

Since the permanent magnet will be demagnetized, in consideration of this point, it is appropriate to increase the degree of excitation of both coils on the side that attracts the movable member and to decrease the degree of excitation on the side that repels the movable member. Note that even if the permanent magnet is slightly demagnetized, it will be automatically re-magnetized the next time it is attracted.

とすることができる。<Effect of the invention> According to this invention, yes! The # part or both ends thereof are moved by the attraction and repulsion forces in the same direction due to the excitation of the coil, so the fluid moves extremely rapidly, and the fluid that flows through the predetermined fluid path is caused by the movement of the rapidly moving movable part. Since it is designed to control electromagnetic waves, it is possible to use electromagnetic waves with high responsiveness.

通電し続けなければならない問題が残る。Further, even if both coils are demagnetized, the current state is maintained, so there is an effect of energy saving and miniaturization. In this regard, in the case of a structure that allows high-speed operation against general spring drag, it is necessary to increase the current to the coil or increase the size of the coil itself, which may cause heat generation and increase in volume. The problem remains. Furthermore, in the case of a sinking structure using a permanent magnet, there remains the problem that the coil must be continuously energized in order to maintain the switched state in the soil where the above-mentioned problem exists.
