Inventor: HARA KAZUYA
IPC: B22D17/30
Filed: 1992-06-15
Abstract: PURPOSE:To sensitize the variation of molten metal surface level to the variation of molten metal quantity and to improve the weighing accuracy by fitting a member for reducing the surface area near the weighing position of the molten aluminum quantity to cover a part of the molten metal surface.

IPC: G01R27/22
Filed: 1995-06-22
Abstract: PURPOSE: To obtain an apparatus for measuring the electric conductivity in which the accuracy of measurement can be enhanced while decreasing the number of components. CONSTITUTION: The apparatus for measuring the electric conductivity comprises an AC reference voltage generation circuit 2, an electrode 1 being applied with the AC reference voltage through contact with an object, a bias setting circuit 7 for superposing a DC voltage on an output signal from the electrode 1, and an AD converter 5 for subjecting an output signal from the bias setting circuit 7 to AD conversion. An AC signal having amplitude corresponding to an electric conductivity obtained from the electrode 1 is applied with a bias voltage and the signal is confined within a range of voltage convertible through the AD converter 5. Since it is not required to convert an output signal from the electrode into a DC signal, rectifying and smoothing circuits are not required and the circuitry is simplified because only one positive power supply is required. The accuracy of measurement can be enhanced by employing a common power supply for the AC reference voltage, bias voltage, and reference voltage.
