Filed: 1985-10-23
Abstract: PURPOSE:To protect a power converter from the overload regardless of a load power factor and the crest value of load currents by drooping output voltage from the power converter when input power to the power converter exceeds a specified value. CONSTITUTION:Outputs from a voltage detecting circuit 2 and a current detecting circuit 3 are inputted to an arithmetic circuit 4, and input power to a power converter 1 is arithmetically operated.

Title: Flow potential measuring method
Inventor: FUKUI TOSHIBUMI
IPC: G01N27/26
Filed: 1994-09-30
Abstract: PURPOSE: To make accurate measuring without setting any specific measuring conditions by correcting the flowing pressure to be measured for its pressure loss resulting from presence of a specimen. CONSTITUTION: A gas with a specified pressure is introduced into a flow liquid vessel 7 under the condition that a cell 4 is not filled with a sample, and a liquid 6 is allowed to flow from the vessel 7 side toward a drain liquid vessel 9 via the cell 4, and the relation between the flow pressure and the rate of flow is determined. Then, under the condition that the cell 4 is filled with the sample, the liquid 6 is alike allowed to flow followed by determination of the relation between the flow pressure and rate of flow., and at the same time, the flow potential E generated between electrodes 3, 3 is measured. The rate of flow of the liquid 6 at this time is smaller than with no sample because of pressure loss resulting from presence of the sample, and because the potential E is in the corresponding relationship, the calculated zeta potential is smaller than the actual value.  To make measurement of the potential E, therefore, comparison is made with the pressure/rate of flow relationship in the condition with no sample, and the influence of pressure loss is corrected through computation. Thereby, the real zeta potential with pressure loss corrected can be obtained, compared with an apparent zeta potential obtained by actual measurement in the condition with sample.
