摘要： In a sparkplug voltage detecting probe device for use in internal combustion engine, a sensor is provided to form a static capacity between the sensor and an ignition coil which Is connected to a spark plug. A sparkplug voltage divider circuit has a capacitor connected between the sensor and the ground. A release circuit has a resistor connected in parallel with the capacitor so as to provide a time constant of a RC path. A short circuit is provided to instantaneously release an electrical charge from the capacitor either immediately before establishing a spark voltage for the spark plug or immediately after initiating the spark action of the spark plug. A sparkplug voltage waveform detecting circuit detects a sparkplug voltage waveform divided by the sparkplug voltage divider circuit, e.g. to detect misfire.

摘要： A device for detecting the mix ratio of a composite liquid (6) has a transparent column (2) placed so that the bottom (22) of the column (2) is in contact with the liquid and a light emitting diode (3) disposed so that light therefrom is incident on one side of the column to pass therethrough so as to be incident on the interface (22a) between the bottom of the column and the mixing liquid. Light incident on the interface at less than the critical angle are refracted, while light is incident on the interface at more than the critical angle is totally reflected to escape from the other side of the column. A photodiode (4) is provided to receive the light beams escaping from the other side of the column and to generate an output. The effective photo-receiving area (41) of the photodiode is in the form of an inverted trapezoid to make the output from the photodiode more linearly dependent on the mix ratio.

摘要： An air/fuel ratio sensor is controlled such that the oxygen concentration of the measurement gas can be detected from a pump current substantially instantaneously after a heater turns on. In the air/fuel ratio sensor an oxygen pumping cell and an oxygen concentration measuring cell are each formed of a solid electrolytic layer interposed between a pair of porous electrodes. One of the electrodes of each cell defines a measurement gas chamber in which the diffusion of the measurement gas is controlled. After a micro current is supplied to the other electrode of the oxygen concentration measuring cell for a predetermined period of time, thereby forming an internal reference oxygen source, the supply of the micro current is stopped and at the same time a pump current in the oxygen pumping cell starts to be controlled until the interelectrode voltage of the oxygen concentration measuring cell reaches a target voltage. After the air/fuel ratio sensor is activated, the supply of the micro current is restarted.

摘要： In a sparkplug voltage probe device which detects a voltage applied to each of spark plugs installed in an internal combustion engine by way of corresponding cables so as to analyse a burning condition in the internal combustion engine on the basis of the voltage applied to each of the spark plugs, an insulator base is attached to the internal combustion engine. An upper surface of the insulator base has a plurality of grooves in which the corresponding cables are placed. An electrode plate is embedded in the insulator base along the grooves to form a static capacity between the electrode plate and the cables. Both sides of the electrode plate are longitudinally extended to be longer than a central portion of the electrode plate to substantially form a capacitance adjusting means so as to even a distribution of the static capacity therebetween.
