6.PTC検査用補償フィルタについて(II.X線撮影用補助具について)

抄録

We've manufactured an easy clairvoyant compensating filter for use in P.T.C. inspection. Its manufacturing was fairly easy, and its effect was big. Using this compensating filter, we could make P.T.C. inspection easy, and reduce the quantity of the radiant rays to fifty percent. We could freely process Kyowa-glass XA, because it was about the same nature as acrylic resin. From the view-point of the photographing subsidiary tool, the meaning of this compensating filter was great.
