を提供することを目的としている。It is an object of the present invention to provide a measuring device which can continuously measure discharge energy such as electrostatic charging or induction, electromagnetic waves, and electrical induction only by a measuring device having a circuit mainly including a coherer and a decoherer.
（課題を解決するための手段） 上記目的を達成するために、本発明の放電エネルギー
測定装置は図に示すごとく、電気抵抗値109Ω以下の材
料で被測定物に適した形状の集電部１よりシールドワイ
ヤー２を通りコヒーラ３を介してアース４に接続する。(Means for Solving the Problems) In order to achieve the above object, the discharge energy measuring apparatus of the present invention is, as shown in the figure, a collector having a shape suitable for an object to be measured with a material having an electric resistance value of 10 9 Ω or less. It connects from the part 1 through the shield wire 2 and the earth 4 through the coherer 3.
一方シールドワイヤー２とコヒーラ３との接続点より
チョークコイル５を通し直流電源７及びデコヒーラ６を
介しアース４に接続する。On the other hand, from the connection point between the shield wire 2 and the coherer 3, the choke coil 5 is passed through and the DC power source 7 and the decoherer 6 are connected to the earth 4.
デコヒーラのコイル８に二次コイル９を巻き、この起
電力を整流器10を通しコンデンサー11とこれに並列に直
流計器（レコーダーも含む）12を結線する。A secondary coil 9 is wound around the coil 8 of the decoherer, and this electromotive force is passed through a rectifier 10 and a capacitor 11 and a DC meter (including a recorder) 12 are connected in parallel with the capacitor 11.
（作用） 被測定物体13の放電エネルギーが集電部１に誘導し、
このエネルギーがシールドワイヤー２を通りコヒーラ３
に感ずるとこのエネルギーがコヒーラ３の作動する大き
さになったときコヒーラ３は急に低抵抗値となる。コヒ
ーラに作動するエネルギーはパルス電流である。(Operation) The discharge energy of the measured object 13 is induced in the current collector 1,
This energy passes through the shield wire 2 and the coherer 3
When feeling this, the coherer 3 suddenly becomes a low resistance value when this energy reaches a level at which the coherer 3 operates. The energy that drives the coherer is a pulsed current.
このパルス電流に対しチョークコイル５は高抵抗値に
なり、このパルス電流は通過しにくい。放電エネルギー
でコヒーラ３が低抵抗値に急変し、直流電源７の電流は
チョークコイル５、コヒーラ３、デコヒーラ６のコイル
８を流れるのでデコヒーラ６が作動しコヒーラ３に衝撃
を与えるので、コヒーラ３は元の高抵抗値に復帰する
と、直流電流の流れが停止しデコヒーラ６のコイル８の
電流も停止する。The choke coil 5 has a high resistance value with respect to this pulse current, and it is difficult for this pulse current to pass through. The discharge energy causes the coherer 3 to suddenly change to a low resistance value, and the current of the DC power supply 7 flows through the choke coil 5, the coherer 3, and the coil 8 of the decoherer 6, so that the decoherer 6 operates and gives an impact to the coherer 3. When the original high resistance value is restored, the flow of the DC current stops and the current of the coil 8 of the decoherer 6 also stops.
この操作によりデコヒーラ６の二次コイル９に交流起
電力が発生し、これを整流器10により直流化しこれがコ
ンデンサー11に充電される。By this operation, an AC electromotive force is generated in the secondary coil 9 of the decoherer 6, and this is converted into a direct current by the rectifier 10 and this is charged in the capacitor 11.
復帰するとすぐコヒーラ３に集電部１より作動するエ
ネルギー−が印加するので、コヒーラ３が再度低抵抗値
に急変し、前期同様デコヒーラ６が作動しデコヒーラ６
の二次コイル９に交流起電力が発生し整流器10により直
流化しこれがコンデンサー11に充電され、これが集積さ
れてこの充電電圧がだんだんと高くなる。Immediately after returning, the energy to operate from the current collector 1 is applied to the coherer 3, so that the coherer 3 suddenly changes to a low resistance value again, and the decoherer 6 operates and the decoherer 6 operates as in the previous period.
AC electromotive force is generated in the secondary coil 9 and is converted into a direct current by the rectifier 10, which is charged in the capacitor 11, which is integrated and the charging voltage is gradually increased.
上記の繰り返す時間は放電エネルギーが高ければ高い
ほど短くなる。繰り返す時間が短いほどコンデンサー11
に充電される電圧が高くなり、これにつれて直流計器12

The fluctuation of the
故に放電エネルギーの大小に直流計器の振れが比例す
るため、直流計器12の振れの目盛りにより放電エネルギ
ーの大小の変化が連続的に測定することができる。Therefore, since the fluctuation of the DC meter is proportional to the magnitude of the discharge energy, the fluctuation of the discharge energy can be continuously measured by the fluctuation scale of the DC meter 12.
（実施例） 集電部１として電気抵抗値105Ω位のベークライト板 300×500mm。(Example) As a current collector 1, a bakelite plate having an electric resistance value of about 10 5 Ω is 300 × 500 mm.

電エネルギーだけが測定することができる。(Effect of the Invention) As described above, the present invention is provided with the current collector 1 and the coherer 3.
Since the shield wire 2 is connected between and, there is no induction of the outer periphery of the shield wire 2 and only the discharge energy collected by the current collector can be measured.
コヒーラ３の電流感度（内部抵抗が低抵抗値に急変す
る感度）は22Vで1pA以下であるため集電部１の電気抵抗
値は109Ω以下で目的を達成する。The current sensitivity of the coherer 3 (sensitivity at which the internal resistance suddenly changes to a low resistance) is 1 pA or less at 22 V, so the electrical resistance of the current collector 1 is 10 9 Ω or less to achieve the purpose.
直流計器12としてレコーダーを使用すると放電エネル
ギーの変化を常時記録することができる。When a recorder is used as the DC meter 12, it is possible to constantly record the change in discharge energy.

が比例していることが明白となった。In order to check the change of discharge energy and the fluctuation of DC meter, the capacitor was charged with DC voltage, the discharge energy at this time was calculated with J = 1 / 2CV 2 , and when this was discharged between the current collector and ground, It became clear that this discharge energy is proportional to the swing of the DC meter.
