In most cases, such a stirring device has a structure in which a propeller is attached to one end of a long rod-shaped rotating shaft, the propeller and the shaft are placed in a solution, and the other end is driven by an electric motor.
電気モータを使用した撹拌装置ではスイッチを入れるだ
けで駆動可能であるが、均質によく撹拌するためには回
転方向を頻繁に変える必要がある。Stirring devices using electric motors can be driven by simply turning on the switch, but in order to stir well and homogeneously, the direction of rotation must be changed frequently.
しかしプロペラの回転方向を頻繁に変える場合には制御
機構が必要となり、また反転機構も備えなければならず
構成はそれだけ複雑となる。However, if the direction of rotation of the propeller is frequently changed, a control mechanism is required, and a reversing mechanism must also be provided, making the configuration that much more complex.
この発明はかかる課題に解決するためになされたもので

する。That is, in order to solve the above-mentioned problems, this invention has an automatic stirring device that uses a shape memory alloy having a fixed shaft with a propeller attached to one end and a current regulator connected to the other end via a lead wire, and It is characterized by consisting of a cylindrical part having a memory alloy and a shaft rotatably attached to its tip, and a cauldron for blowing air to the shape memory alloy within the cylindrical part.
〔作 用］
当初、温かい温度で伸びた状態とし、室温で図に示すよ
うに捩じられた状態としておく。[Function] Initially, it is stretched at a warm temperature, and then twisted at room temperature as shown in the figure.
電流調節器により形状記憶合金に電流を流して行（と温

より溶液は良（撹拌されることになる。A current is applied to the shape memory alloy using a current regulator, and the temperature gradually rises and the propeller begins to rotate.Next, the current regulator is switched off, and the shape memory alloy is heated by a corder. Cooling air is blown onto the shape memory alloy.This time, the shape memory alloy returns to its twisted state and begins to rotate in the opposite direction.If the shape memory alloy is repeatedly heated and cooled in this way, the propeller placed in the liquid The solution will be well (stirred) by rotating it forward and backward.
以下、この発明の具体的実施例について図面を参照して
説明する。Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.
第１図はこの発明にかかる自動撹拌装置の構成を示す図
である。この図で、１は形状記憶合金であって先端部は
回動自在な軸２に連結されている。FIG. 1 is a diagram showing the configuration of an automatic stirring device according to the present invention. In this figure, 1 is a shape memory alloy whose tip end is connected to a rotatable shaft 2.
これらの形状記憶合金１と軸２はシール１１を介して円
筒３内に配置されている。そして前記軸２にはプロペラ
４が取付けられ一体になって回転出来るようにしである
。また、前記形状記憶合金１の後端部（上端部）はリー
ド線７が接続されているが、該リード線７は電源６に接
続された電流調節器５に接続されている。即ち、前記形
状記憶合金１は該リード線７を介して温度調節されるよ
うになっている。These shape memory alloy 1 and shaft 2 are placed in a cylinder 3 via a seal 11. A propeller 4 is attached to the shaft 2 so that they can rotate together. Further, a lead wire 7 is connected to the rear end (upper end) of the shape memory alloy 1, and the lead wire 7 is connected to a current regulator 5 connected to a power source 6. That is, the temperature of the shape memory alloy 1 is controlled via the lead wire 7.
次に、８はコルダーであってエアー源（高圧エアボンベ
或いはコンプレッサー）９からのエア供給により冷却空
気（氷点下５°Ｃ〜常温）を前記円筒３内の形状記憶合
金ｌに吹きつけるようにしである。この場合冷却エアの
供給量はコルダー調節ハネｌＯにより８周節するように
しである。Next, 8 is a caulder which blows cooling air (below 5°C to normal temperature) onto the shape memory alloy l in the cylinder 3 by supplying air from an air source (high-pressure air cylinder or compressor) 9. . In this case, the amount of cooling air supplied is adjusted to 8 cycles by the Calder adjustment spring 10.
この発明にかかる自動撹拌装置の構成は以上のようであ
るが、次にその作用について説明する。The structure of the automatic stirring device according to the present invention is as described above, and its operation will be explained next.
当初、温かい温度（例えば７０°Ｃ程度）で伸びた状態
とし、室温（例えば２０°Ｃ程度）で図に示すように涙
しられた状態としておく。Initially, it is stretched at a warm temperature (for example, about 70°C), and then left at room temperature (for example, about 20°C) in a weeping state as shown in the figure.
前記電流調節器５により形状記憶合金１に電流を流して
行くと温められて徐々に温度が上昇し、プロペラ４が回
転を始める。次に、前記電流調節器５のスイッチを切り
、コルダー８により該形状記憶合金１に冷却エアを吹き
つける。すると今度は該形状記憶合金ｌは捩じられた状
態に戻るため逆方向に回転を始める。When a current is passed through the shape memory alloy 1 by the current regulator 5, the shape memory alloy 1 is heated and its temperature gradually rises, and the propeller 4 starts rotating. Next, the current regulator 5 is switched off, and the colder 8 blows cooling air onto the shape memory alloy 1. Then, the shape memory alloy 1 returns to its twisted state and begins to rotate in the opposite direction.
このように形状記憶合金ｌに対して加熱と冷却を繰り返
せば液中に入れたプロペラ４の正逆回転により溶液は良
く撹拌されることになる。If the shape memory alloy 1 is repeatedly heated and cooled in this way, the solution will be well stirred by the forward and reverse rotation of the propeller 4 placed in the liquid.
以上の実施例においては、勿論形状記憶合金を当初、温
かい温度で捩じられた状態態とし、室温で伸びた状態と
