The author used an electro-nozzle to make micro-holes in metals in place of a drilling machineo,
In previous report he studied the characteristics of electro-nozzle using copper. In this report he developed his view based on the results of his experiments with nickel.
These experiments using orthophosphoric acid solution showed that the difference in characteristic curves of the speed at which cell voltage is raised is rather negligible below the specific point C. Then it is found that the curve is almost always fixed in all electrolytic conditions mentioned above, the differing conditions of dissociation according to the degrees of concentration of this solution are represented by the shifting of the curves and futher, at fixed value of cell voltage, valuation of current through the cell is regarded as fluctuation about the reference value below the specific point C.
Finally a formula was derived from both to the electrolytic conditions of electro-nozzle and its formative function, by which he showed the possibility of analysis of the working power of the nozzle.
