Title: Direct current breaker
Inventor: YOKOKURA KUNIO
IPC: H01H33/59
Filed: 1991-09-30
Abstract: PURPOSE:To break direct currents in both positive and negative directions with one current source circuit by connecting a series circuit of a diode and thyristor connected in reverse parallel and a capacitor in parallel with a vacuum breaker, and connecting a DC auxiliary power source to the capacitor. CONSTITUTION:The discharge current of a capacitor 7 is formed to an oscillating current reversed alternately in positive and negative directions in a vacuum breaker 1.

Title: Oxygen sensor, heater control apparatus for oxygen sensor and oxygen concentration-detecting apparatus
Inventor: IIO MOTOAKI
IPC: G01N27/41
Filed: 1999-09-07
Abstract: PROBLEM TO BE SOLVED: To correctly detect a temperature of a solid electrolyte and correctly hold the solid electrolyte to a preliminarily set temperature by setting a temperature sensor for directly detecting the temperature of the solid electrolyte to be in direct touch with the solid electrolyte. SOLUTION: When a temperature of a solid electrolyte 11 rises or drops, a temperature of a hot junction S of a thermocouple 16 also rises or drops and becomes equal to the temperature of the solid electrolyte 11. In consequence of this, an electromotive force corresponding to the temperature of the solid electrolyte 11 is generated between both ends (a) and (b) of the thermocouple 16. A heater control apparatus 30 directly detects the temperature of the solid electrolyte 11 by the thermocouple 16 and controls heating of a heater 15 to make the temperature of the solid electrolyte 11 a constant predetermined temperature. The temperature of the solid electrolyte can be correctly kept to be the preliminarily set predetermined temperature.  Therefore, in order to detect a current generated with oxygen ions conducted in the solid electrolyte 11 used as carriers by a current-detecting part 20, a conductivity of the solid electrolyte 11 can be made constant at all times.
