い。When the patient's clothes are to be irradiated with microwaves from the microwave treatment device, the practitioner must use the device's 11! The patient turns on the source switch 15, grasps the handle 12 of the detector 11, brings the irradiator 8 close to the flat surface of the patient's clothing, and irradiates the patient with microwaves. While irradiating, the detector 11 is rotated about 180 degrees around the irradiation axis without changing the location of the detector 11, and the movement of the needle of the ammeter 10 is observed. Detector 11 about 1
If the deflection of the needle increases or decreases while rotating 80 degrees, metal fibers are woven into the garment. On the other hand, if the needle deflection does not change, there is no metallic fiber woven into the garment.

電力のマイクロ波が発振する。発振したマイクロ波をア
イソレーター４で進行波のみを減衰器５に送電するので
発振器３に逆伝送されて発振器３を破壊することの無い
ように前記アイソレーター４が作用する。In operation of the detector 11, when the power source 2 in the cylindrical body 14 is supplied to the oscillator 6 via the conductor 1, the oscillator 6 oscillates a low-power microwave for measurement. Since the isolator 4 transmits only the traveling wave of the oscillated microwave to the attenuator 5, the isolator 4 acts to prevent it from being reversely transmitted to the oscillator 3 and destroying the oscillator 3.

れる。The microwave is adjusted to an appropriate amount of power by the attenuator 4 and reaches the directional coupler 7, and the microwave output from the directional coupler 7 and coupled to the irradiator 8 is transmitted from the irradiator 8 to the fabric of the object to be measured. Since the irradiation opening end of the zero detector 11 is circular, when the detector 11 is rotated, the entire surface of the object to be measured is uniformly irradiated with microwaves. When metal fibers are present in the cloth, a counter-backward wave is generated, and this reflected wave is received by the irradiator 8 and flows through the irradiator 8 and the directional coupler 7 in the opposite direction to the direction of the traveling wave.

って変化する。即ち円筒導波性モードの電界と平行方向

が小さくなる。When the metal fibers of a cloth are irradiated with microwaves, the intensity of the reflected waves changes as the microwave irradiation angle changes. In other words, when the metal fibers are aligned in a direction parallel to the electric field of the cylindrical waveguide mode, the reflected microwave wave becomes large.
When the metal fibers are lined up in the direction of the electric field and plane angle, the reflected microwave waves become smaller.
布巾に金属繊維が織り込まれていなけれは反射波の変化
は生じない。Unless the cloth is woven with metal fibers, there will be no change in the reflected waves.

There is.

ようになった。Metal fibers in the cloth can be detected by irradiating low-power microwaves for measurement with a hand-held detector on the flat part of the cloth, and observing the deflection of the ammeter needle while rotating the detector approximately 180 degrees. The system is designed so that it is possible to determine the presence or absence of As a result, metal fibers can be detected extremely easily, quickly and accurately without destroying the patient's clothes and without requiring the patient to take off their clothes, thereby preventing the disaster of burning clothes during microwave irradiation treatment. Microwave irradiation treatment can now be performed safely and securely while wearing clothes.
