てアマチャを水平往復移行する有極型電磁石装置に関す
る。Detailed Description of the Invention (Field of Application) The present invention is a polarized type in which a permanent magnet is interposed in a magnetic circuit, and the magnetomotive force of the coil is superimposed on the magnetic flux of the permanent magnet, and the magnetomotive force of the coil is attenuated to move the armature horizontally back and forth. Relating to electromagnetic devices.
（従来技術の問題点）
この種、電磁石装置として第４図及び第５図のものが先
行技術として存在する。(Problems with the Prior Art) As this type of electromagnetic device, those shown in FIGS. 4 and 5 exist as prior art.
即ち、第４図は上下片４０口及び左右側片ハ。That is, FIG. 4 shows 40 upper and lower pieces and 40 left and right side pieces.

を巻付けている。2 forms a box-shaped yoke, and a permanent magnet is placed on the inner surface of the upper and lower pieces 41, one at the top and one at the top, and the upper and lower magnetic Board Chi,
A horizontally moving armature is placed facing the upper and lower magnetic plates, and a coil is wound around this armature.

ヤーギャップを小さくするよう空隙を縮めており、その
ためコイルスをこの部分には巻けず、左右に分割して巻
付ける。ところが、曹−クホとの関係から巻付中にも限
界がある。In this structure, the air gap between the magnetic plates 1 and 2 and the armature is narrowed to reduce the air gap, so the coils cannot be wound around these parts, so they are wound on the left and right sides. However, due to the relationship between Cao and Kuho, there are limits to the wrapping process.
又、第５図については、■−クホの一方片を除去したコ
字型とし、磁性板りの一端にアマチャヌと対峙する折曲
片オを形成しているが、これとてもコイルルはこの折曲
片オによって巻巾には限界かある。Also, regarding Fig. 5, one piece of the ■-kuho is removed to form a U-shape, and one end of the magnetic board is formed with a bent piece facing the Amachanu. There is a limit to the roll width depending on the size.
なぜならば、この折曲片オをヨークホの側片二に余り近
づけると、この側片二からアマチャヌの右端に流れる磁
束がこの折曲片方に直接短絡してしまうからである。This is because if this bent piece O is brought too close to the side piece 2 of the yoke, the magnetic flux flowing from this side piece 2 to the right end of the amachanu will be directly short-circuited to this bent piece.
（目 的）

ことを目的としたものである。(Purpose) The present invention has been made in view of the above points, and an object of the present invention is to wind a coil around a yoke so that its winding width can be maximized.

In Fig. 1, 1 is a permanent magnet, 2 is a U-shaped yoke, and one side of the magnetic axis of this permanent magnet 1 is The pole is brought into contact with the one-night moon 3 having an air gap l, and the left and right pieces 5.6 form a U-shape with the other piece 4. This other piece 4 has a coil 7
Wrap around. A magnetic plate 8 is attached to the other pole of the permanent magnet 1 over its entire length. 9 is a horizontal transfer type amateur,
facing the lower surface of the magnetic plate 8, and both left and right ends 91°9b
are opposed to and separated from the left and right pieces 5.6 of the U-shaped yoke 2. X is the magnetic flux of the coil, and Y is the magnetic flux of the permanent magnet 1. In FIG. 1, the yoke 2 is not strictly U-shaped but box-shaped, but in FIG. The armature 9 is located at the top. Furthermore, in FIG. 3, an air gap 1 is formed at the corner of the yoitsuki 3 and the right side piece 6.

、左右側片５．６、アマチャ９、磁性板８にと至る。(Operation) Next, the operation of the polarized electromagnet device of the present invention will be explained.
In the figure, the magnetic flux Y of permanent magnet 1 is permanent magnet 1, - Yozuki 3.
, the left and right side pieces 5.6, the armature 9, and the magnetic plate 8.
この状態でコイル７に磁束Ｘを起磁させると、ヨーク２
の他方片４、右側片６、アマチャ９、左側片５と至る。When the magnetic flux X is generated in the coil 7 in this state, the yoke 2
The other piece 4, the right side piece 6, the armature 9, and the left side piece 5 are reached.

Even if the magnetomotive force of the coil 7 is demagnetized, the state is maintained by the magnetic flux of the permanent magnet 1.
次に、フィル７に逆向の起磁力を作用させるとその磁束
は逆向となり、アマチャ９は左方向に逆転移行する。Next, when a magnetomotive force in the opposite direction is applied to the fill 7, the magnetic flux is reversed, and the armature 9 is reversely shifted to the left.
