せ、液体６を攪拌させるものであった。2. Description of the Related Art Conventional liquid stirring involves heating the liquid in a container 1 using a high frequency coil 6 to generate natural convection, as shown in FIG. In addition, when stirring actively,
As shown in FIG. 9, a plate-like object 7 or a rod-like object 8
The object was brought into contact with liquid 6, and the object was rotated by an external motor to agitate the liquid 6.

Also, it takes time to place the stirring object in a predetermined position so as not to have a chemical or thermal effect on the liquid.
更に、液体の回転は攪拌物体の面積あるいは形状に大き

最後に、攪拌物体に液体が付着してしまい、液体の成分
や組成を変化させる可能性がある。Furthermore, the rotation of the liquid is greatly affected by the area or shape of the stirring object, and the entire liquid cannot be stirred in a similar manner. In particular, in the case of multi-element LPE (liquid phase epitaxy), the composition of the crystal varies depending on the degree of mixing of the liquid phases, so if stirring is insufficient, the reproducibility of growth will be poor. Also, if the stirring object has reactivity with the liquid, the composition of the liquid may change.Finally, the liquid may adhere to the stirring object, changing the composition or composition of the liquid. There is.
この発明は、従来のものがもつ上記のような問題点を解

構成としている。Means for Solving the Problems In order to achieve the above object, the present invention is as follows. ,
It is structured as follows.

場合であっても液体に比較して慣性の大きなものを意味
し、児かけの上で、磁界を感じない容器のことである。That is, for example, the multiphase winding according to the present invention is installed around the liquid container at a position spatially shifted by an appropriate phase.The liquid container here is a non-electrically conductive and non-magnetic container, or Alternatively, even if it has either of the above, it means a container that has a large inertia compared to a liquid, and does not feel a magnetic field when placed on a child support.
この多相巻線に多相電流を加えると周知の通シ回伝磁界
が発生する。そして、電気伝導性あるいは磁性を有して
いる液体は前記の回転磁界を減じ液体自身が回転し始め
る。When a multiphase current is applied to this multiphase winding, a well-known circulating magnetic field is generated. Then, the electrically conductive or magnetic liquid subtracts the rotating magnetic field, and the liquid itself begins to rotate.
また、液体が非電気伝導性かつ非磁性を有している場合

。Furthermore, when the liquid is non-electrically conductive and non-magnetic, particles or liquid that do not interact with the liquid and have electrical conductivity or magnetism are mixed into the liquid. Then, the particles or liquid feel the rotating magnetic field, and the particles or liquid begin to rotate by themselves. Then, due to the physical interaction between the particles or liquid and the non-electrically conductive and non-magnetic liquid, the non-electrically conductive and non-magnetic liquid also begins to rotate.

による液体の回転のむらが解消できる。Effect By using the rotating magnetic field produced by the multiphase winding as described above, there is no need for a stirring object υ, and the above-mentioned problems caused by the interaction between the stirring object and the liquid are eliminated. Since it can be stirred quickly, there is no need to worry about misalignment of the crystal structure. In addition, when the multiphase current is stopped, the rotating magnetic field disappears, and since there is no contact between the windings and the liquid container or liquid, there is no need to clean, store, or move the windings, which saves time and effort during stirring work. In addition, if the area of the winding loop is made larger than that of the liquid container, an approximately -like rotating magnetic field will be applied to the entire liquid, which will eliminate the uneven rotation of the liquid due to the area of the stirring object described in 2. .

In this embodiment, as shown in FIGS. 1 and 2, the symmetry axis of the three-phase windings is placed inside the rectangular three-phase windings 2, 3.4, which are distributed spatially shifted by 2π/3. The liquid container is installed so that the axis of symmetry of the cylindrical liquid container 1 coincides with the symmetry axis of the cylindrical liquid container 1. The loop area of the three-phase winding is larger than the cross-sectional area of the liquid container, and the winding is arranged so as to cover the liquid container 1. Here, the three-phase winding is The windings are electrically insulated from each other. At the above-mentioned upper and lower intersections, the three-phase winding is pinned so that it has a degree of freedom in rotation around the intersection when the liquid container is taken in and out. 1st

The electrically conductive or magnetic substance senses this rotating magnetic field and begins to rotate at the aforementioned frequency. However, this rotation can be reversed by switching the currents in two of the three phases using a switch. By applying the above principles, it is possible to stir liquids such as solutions for liquid phase growth of compound semiconductors such as OGa and As without contact and with good controllability. Growth solution is G
It contains elements such as a and As, and since these respond to a rotating magnetic field, it is possible to stir the solution.
