Title: Doubling control system for automatic pulse phase shifter
Inventor: ETOU SHIYUUICHI
IPC: H02P9/30
Filed: 1982-09-10
Abstract: PURPOSE:To enable to perform the maintenance of an automatic pulse phase shifter by supplying the gate pulse of a manual/automatic pulse phase shifter as standby system to an automatic pulse phase shifter monitor and inhibiting the switch to the standby system when a malfunction is detected. CONSTITUTION:The output V of a generator G is inputted through a voltage transformer 1 to an automatic voltage regulator 2. The output voltage of a generator G is compared by a device 2 with an instruction value S at the control operation time, and a control signal is outputted to an automatic system controller 3 and a manual system controller 4. Normally, the automatic system is selected, and the output voltage of the generator G is controlled from an automatic system automatic pulse phase shifter 6A. When the phase shifter 6A is further operated, a suppress signal 13 is fed to the manual system automatic pulse phase shifter 6M which becomes the standby system when the phase shifter 6A is operated, thereby inhibiting the output. On the other hand, basic pulses 16a, 16b are inputted from phase shifters 6A, 6M to pulse malfunction monitor 15 in the automatic pulse phase shifter. The monitor 15 indicates the malfunction when detecting the malfunction, and feeds a signal 18 to the automatic system/manual system switch 5, thereby inhibiting the switch.

Title: Oxygen sensor for internal combustion engine
Inventor: UCHIKAWA AKIRA
IPC: G01N27/409
Filed: 1988-06-28
Abstract: PURPOSE:To obtain an O2 sensor which enables control of an air/fuel ratio to reduce nitrogen oxide in the use of an alcohol mixed fuel by providing an NH3 oxidation catalyst layer on the outermost surface of an O ion conductive electrolyte while a nitrogen oxide reducing catalytic layer is provided thereinside. CONSTITUTION:A Pt catalyst layer 4 and a protective layer 5 made of Mg spinel on an external surface of a ceramic tube 1 is provided with a reducing catalyst layer 6 and an oxide catalyst layer 7 by lamination. The reducing catalyst layer 6 has TiO2, La2O3, Al2O3 or the like as carrier and contains 0.5-5wt.% of a reducing catalyst such as Rh and Pu. The oxidizing catalytic layer 7 has Al2O3 or the like as carrier and contain 0.1-5wt.% of a Pt catalyst and 0.2wt.% of Ni catalyst. With such an arrangement, NH3 generated in large quantities at a low temperature reacts with O2 in an exhaust in the layer 7 to be kept from reaching Pt4, which prevents deviation of electromotive characteristic of an O2 sensor to the lean side, so that NO in the layer 7 and the exhaust reacts with unburned CO and HC in the layer 6. This reduces a difference in the concentration of O2 between a value inside the ceramic tube 1 contacting atmospheric air and that an exhaust side to accomplish a lean detection. When a feedback is performed based on a detection of the sensor, an air/fuel ratio can be lean detected on the rich side with the more of an N oxide.
