IPC: B60W10/10
Filed: 1986-06-20
Abstract: PURPOSE:To perform disengagement of a gear smoothly by arranging a valve means for driving an actuator from a position of a smaller action force side to a neutral position thereby retaining the actuator at the neutral position after controlling the valve means. CONSTITUTION:When a gear disengagement is performed, a shift stroke position is judged by a shift stroke sensor for sensing the shift stroke position whether it is on the shift side or neutral side relative to a set value. In the case it is on the shift side, firstly only one solenoid valve V1 is actuated to drive a shift actuator 1 with a greater disengagement force. Then a 2nd solenoid valve V2 is actuated to retain a neutral position. With this arrangement, a smooth gear disengagement can be performed as the disengagement is performed with a sufficient force.

Title: Method for testing oxygen sensor element
Inventor: UCHIDA MASAAKI
IPC: G01N27/407
Filed: 1980-10-20
Abstract: PURPOSE:To obtain the maximum allowable current value, by flowing a gradually increasing current into the oxygen sensor element which controls partial oxygen pressure at a reference electrode by flowing a DC current in solid state, electrolyte, and measuring the output voltage from the sensor element at that time. CONSTITUTION:The temperature of a reference electrode conductor 4 of the oxygen sensor 1 is kept at a suitable value by connecting a heater 2 to an external power source 8. An external power source 9 whose current value gradually increases with the elapse of time at a constant rate is connected between said conductor 4 and a measuring electrode conductor 6. The output voltage of the oxygen sensor 1 gradually increases end becomes the voltage which is the sum of the emf of the oxygen sensor element 1 and the voltage obtained by multiplying said current value by the internal resistance of the solid state electrolyte 5. Therefore the output voltage of the oxygen sensor element 1 increases depending on said current value. If the partial oxygen pressure of the reference electrode exceeds the bonding power between the solid state electrolyte 5 and the reference electrode conductor 4 or the mechanical strength of the solid state electrolyte 5, separation or cracks occur and the output voltage drastically changes. The current value immediately before said change is the maximum allowable current value.
