Title: Measurement of activity of solute element in molten metal
Inventor: SASABE MINORU
IPC: G01N27/411
Filed: 1988-09-07
Abstract: PURPOSE:To detect the activity aM1 of an objective element with high accuracy by determining the oxygen electromotive force E1 and temperature T of a molten metal by use of a solid electrolyte having oxygen ion conductivity and determining the electromotive force E1 of the objective element by use of a solid electrolyte having oxygen conductivity and covered with an oxide which contains the objective element. CONSTITUTION:When an oxygen sensor comprising a solid electrolyte covered with MOx is dipped in a molten metal containing the solute element M, a local equilibrium layer is formed at the interface of the coating and the molten metal. The activity aM1 of the element M in the molten metal is a function of the activity of oxygen a01, activity of oxygen a02 in the equilibrium layer and temperature T, caused by the correlation due to decomposition of the coating layer. The a01 and a02 can be determined from the electromotive force E1 and E2, which means that aM1 becomes a function of E1, E2 and T. As the oxygen electromotive force E1 is taken in consideration on determination of the activity aM1, accuracy of the measurement is improved. Thereby, the activity of element such as Mn, Cr, etc., in a molten metal can be determined with high accuracy.

Title: Constant current/voltage circuit
Inventor: ISHIBASHI KOICHIRO
IPC: G05F1/46
Filed: 1990-08-29
Abstract: PURPOSE:To obtain a constant current/voltage circuit having the small temperature dependency by actuating a specific MOSFET in a large current active area outside a subthreshold area. CONSTITUTION:The current flowing to a MOSFET Q2 working in a so-called subthreshold area where a minute current flows increases in response to the temperature rise. On the other hand, a MOSFET Q3 whose drain-source path is connected in series to that of the MOSFET Q2 works in a large current active area outside the subthreshold area. Therefore the current flowing to the MOSFET Q3 is reduced in response to the temperature rise. Thus the temperature dependency is offset between the currents of both MOSFET Q2 and Q3. Therefore the current flowing the serial path between both Q2 and Q3 is kept almost constant regardless of the temperature change. Thus a constant current/ voltage circuit having the small temperature dependency is obtained.
