。Conventionally, as a method for controlling the amount of phase shift of the Faraday spiral waveform reversible phase shifter shown in Fig. 1, a conducting wire (
A method has been used in which the total amount of magnetic flux change within the ferrimagnetic material 11) is detected by 7; and this total amount of magnetic flux change is controlled.

１１から構成されておシ、以下に順を追って駆動回路の
動作説明を行なう。This drive circuit includes an exciter (91, integrator a, comparator u
The operation of the drive circuit will be explained below in order.
第１に励磁器（９１により、磁化用導ｍ １６３に電流
を流し、従来のファラデー旋波子形可逆移相器のフェリ
磁性体（１）とヨーク（５１よりなる磁気回路を飽和磁
化状態とする。First, an electric current is applied to the magnetization conductor m 163 by an exciter (91), and the magnetic circuit consisting of the ferrimagnetic material (1) and the yoke (51) of the conventional Faraday rotary waveform reversible phase shifter is brought into a saturated magnetized state. .
この場合の電流をリセット電流と呼ぶことにする。The current in this case will be called a reset current.
第２に、リセット電流を遮断し、磁気回路に飽和磁化を
残留させる。Second, the reset current is cut off and saturation magnetization remains in the magnetic circuit.
第３に、磁化用導線（６）に、リセット電流とは逆方向
に電流を流す。Thirdly, a current is passed through the magnetization conducting wire (6) in the opposite direction to the reset current.
この場合の電流をセット電流と呼ぶことにする。The current in this case will be called a set current.
この時、同時に、フェリ磁性体（１）と磁気回路を形成

導Ｈ１７１により、総磁束の時間変化に対応した誘起電
圧Ｖを検出する。At this time, at the same time, the induced voltage V corresponding to the time change of the total magnetic flux is detected by the conductor H171 that detects the total magnetic flux wound around the yoke (5) forming a magnetic circuit with the ferrimagnetic material (1). do.
この誘起電圧■は積分器０１により第１式に示すように

そこでこの残留磁化状態のフェリ磁性体（１）内を通過
した円偏波は、総磁束変化量φにほぼ比例した位相変化
を受けることになる。Therefore, the circularly polarized wave that has passed through the ferrimagnetic material (1) in this residual magnetized state undergoes a phase change that is approximately proportional to the total magnetic flux change amount φ.

の導ｆｆｓ＋７１によりフェリ磁性体（１１内の総磁束
変化量を検出し、この総磁束変化量を地軸回路により制
御し、移相量の制御を行なっている。As explained above, the conventional Faraday rotary waveform reversible phase shifter detects the amount of change in the total magnetic flux in the ferrimagnetic material (11) using the guide ffs+71, which is used to detect the total magnetic flux wound around the yoke (5). However, this total amount of magnetic flux change is controlled by the earth axis circuit, and the amount of phase shift is controlled.
ところが、上記のように駆動される移相器では温度が磁
化すると所要の移相量が得られないという欠点があった
。However, the phase shifter driven as described above has a drawback in that the required amount of phase shift cannot be obtained when the temperature becomes magnetized.
以下に、この原因について述べる。The cause of this will be described below.
第３図に、従来のファラデー旋波子形可逆移相器の温度
ＴＩ、 Ｔ２ （Ｔｔ＜Ｔ２）における総磁束変化量と
移相量との関係を示す。FIG. 3 shows the relationship between the amount of total magnetic flux change and the amount of phase shift at temperatures TI, T2 (Tt<T2) of a conventional Faraday spiral waveform reversible phase shifter.
図示のように、温゛度が低くなると、総磁束変化骨を一
定の値に保っても、移相量が少なくなる傾向がある。As shown in the figure, as the temperature decreases, the amount of phase shift tends to decrease even if the total magnetic flux change bone is kept at a constant value.
これは、７工リ磁性体＋１＋内の円偏波の伝送電力密度
が、フェリ磁性体（１）横断面内において不均一に分布
すること、および残留磁束密度のフェリ磁性体（１）横
断面内における分布が温度変化するというシつの現象に
起因する。This is because the transmission power density of circularly polarized waves in the ferrimagnetic material +1+ is unevenly distributed within the cross section of the ferrimagnetic material (1), and the residual magnetic flux density is distributed unevenly within the cross section of the ferrimagnetic material (1). This is due to the phenomenon that the distribution within the temperature changes.
以下に、この２つの現象が起こる原因について詳細に述
べるとともに、総磁束変化縫勿制側１することが、移相
量の温度変化に関係することを説明する。In the following, the causes of these two phenomena will be described in detail, and it will be explained that the total magnetic flux change on the sewing side 1 is related to the temperature change in the amount of phase shift.
まず１円偏波の伝送電力密度分布について述べる。First, we will discuss the transmission power density distribution of single circularly polarized waves.
第４図に、正方形断面のフェリ磁性体（１）横断面内に
おける円偏波の伝送電力密度分布會示す。FIG. 4 shows the transmission power density distribution of circularly polarized waves in the cross section of the ferrimagnetic material (1) having a square cross section.
、円偏波は、Ｔ田０モード波とＴＥｏ＋モード波の合成
波であるため、フェリ磁性体（１）の中心近傍に伝送電
力が集中した分布？もつ。Since the circularly polarized wave is a composite wave of the T0 mode wave and the T0+ mode wave, the transmission power is distributed near the center of the ferrimagnetic material (1). Motsu.
このことから、フェリ磁性体（１）中心近傍の磁束変化
が１円偏波の位相変化に主に寄与することがわかる。From this, it can be seen that the magnetic flux change near the center of the ferrimagnetic material (1) mainly contributes to the phase change of the circularly polarized wave.
次に、磁留磁束密度がフェリ磁性体（１）横断面内で不
均一に分布する理由と、この分布が温度変化する理由に
ついて述べる。Next, the reason why the magnetic flux density is unevenly distributed within the cross section of the ferrimagnetic material (1) and the reason why this distribution changes with temperature will be described.
まず、リセット１！流を流した後のフェリ磁性体は）横
断面内飽和残留磁束密度分布を第５図中実線で示す。First, reset 1! The saturated residual magnetic flux density distribution in the cross section of the ferrimagnetic material after flowing the current is shown by the solid line in FIG.
この状態では、残留磁束密度分布は一様である。In this state, the residual magnetic flux density distribution is uniform.
次に、前述の駆動回路により、総磁束変化量が所定の値
になるまで、リセット電流とは逆方向にセット電流を流
し、磁気回路を磁化する。Next, the aforementioned drive circuit causes a set current to flow in the opposite direction to the reset current until the total amount of change in magnetic flux reaches a predetermined value, thereby magnetizing the magnetic circuit.
この時、フェリ磁性体＋１１とヨーク蝿５）より成る磁

なる。At this time, if the DC magnetic field applied to the outer circumference side of the magnetic circuit consisting of ferrimagnetic material +11 and yoke fly 5) is Hout, and the DC magnetic field applied to the inner circumference side is Hin, then the magnetic path length on the outer circumference side is longer than that on the inner circumference side. Therefore, Hout is smaller than Bin.

束密度とセット電流遮断後の残留磁束密度の差、すなわ
ち残留磁束密度変化量は小さくなる。In this way, compared to the vicinity of the tube wall of the ferrimagnetic material that forms the magnetic circuit on the outer circumferential side (near the center of 11 is the ferrimagnetic material that forms the magnetic circuit on the inner circumferential side; Since the strength of demagnetization is weak, the difference between the residual magnetic flux density after the reset current is cut off and the residual magnetic flux density after the set current is cut off, that is, the amount of change in the residual magnetic flux density becomes small.
したがって、残留磁束密度が不均一に分布する。Therefore, the residual magnetic flux density is distributed non-uniformly.
この状態のフェリ磁性体（１１横断面内の残留磁束密度
分布の一例を第５図中破線で示す。An example of the residual magnetic flux density distribution within the cross section of the ferrimagnetic material (11) in this state is shown by the broken line in FIG.

分布が、温度により変化する様子を示している。Figure '$6 shows how the distribution of the residual magnetic flux density change in the cross section of the ferrimagnetic material 11) changes depending on the temperature when the total magnetic flux change is controlled equally.
この様に、残留磁束密度変化量の不均一な分布が、温度
変化する理由全説明する。In this manner, the reason why the non-uniform distribution of the amount of change in residual magnetic flux density causes temperature changes is fully explained.
第７図（ａ） （ｂ）に、磁気回路に用いているフェリ
磁性体材料の温度ＴＩ、Ｔ２におけるＢ−８曲線の一例

、保持力Ｈｅが大きくなる。FIGS. 7(a) and 7(b) show an example of the B-8 curve at temperatures TI and T2 of the ferrimagnetic material used in the magnetic circuit. At low temperatures, the magnetic circuit is less likely to be magnetized and the coercive force He increases.
このため、所定の量の総磁束変化を行なうには高温状態

磁性体；１）内の直流磁界を大きくする必要がある。Therefore, in order to change the total magnetic flux by a predetermined amount, it is necessary to increase the set current and the DC magnetic field in the ferrimagnetic material (1) in a low temperature state compared to a high temperature state.

Since the residual magnetic flux density change near the center of the ferrimagnetic material (1), which mainly contributes to the phase change, is smaller than that around the ferrimagnetic material (1), the conventional Faraday rotary structure is driven using a method that controls the total magnetic flux change. In the waveform reversible phase shifter, the amount of phase shift is reduced from a required value.

器。[Claims] A first permanent magnet is constructed by arranging four permanent magnets around a ferrimagnetic material whose side surfaces are coated with metal so that the north pole and the south pole face each other in a predetermined direction. a second circularly polarized wave generator and a yoke forming a magnetic circuit on the side surface of the ferrimagnetic material;
A Faraday rotary wave element type reversible phase shifter comprising a Faraday rotary wave element formed by winding a magnetizing conductor around a ferrimagnetic material. A hole is provided in a part of the yoke so as to separate the magnetic circuit into an inner periphery and an outer periphery, and a magnetic flux detection conductor is wound around the yoke through the hole so as to surround the magnetic flux in the magnetic circuit on the outer periphery. A Faraday rotary waveform reversible phase shifter.
