摘要： A gas sensor control device is disclosed as including a sensor cell having a negative terminal, to which a current-voltage converter is connected, and a differential amplifier is connected to the current-voltage converter to provide a current measured result applied to a microcomputer. The current-voltage converter has an opposite-to-sensor terminal to which another differential amplifier is connected. A sensor-side terminal of the current-voltage converter and another differential amplifier is electrically connected to each other via an electric pathway having a sensor-current flow disabling pathway in which a switch circuit is provided. Closing the switch circuit allows a potential difference between both terminals of the current-voltage converter is zeroed. With the switch circuit closed, the microcomputer calculates an element current correcting value, while detecting an electromotive force of the sensor cell based on which a failure is determined.

摘要： A gas concentration measuring apparatus for use in air-fuel ratio control of automotive engines is designed to determine the concentration of oxygen within a wide and a narrow range using a sensor current flowing through a sensor element. The apparatus includes an amplifier circuit equipped with an operational amplifier and a plurality of amplifying resistors and a switch. The switch is responsive to a request signal to switch a relation in electrical connection between an operational amplifier and the amplifying resistors to distribute the amplifying resistors into an input resistor and a feedback resistor for the operational amplifier to change an amplification factor of the amplifier circuit. This results in a change in resolution of measurement of the concentration of oxygen, thereby ensuring enhanced accuracy in determining the concentration of oxygen in a selected one of the narrow and wide ranges.

摘要： An apparatus for driving a discharge lamp includes a piezoelectric transformer connected to the discharge lamp. A drive device operates for feeding controllable power to the discharge lamp via the piezoelectric transformer to controllably drive the discharge lamp. A lighting control device operates for controlling the drive device to light the discharge lamp. In addition, the lighting control device operates for controlling the drive device to feed a first current to the discharge lamp during a build-up time interval before the discharge lamp changes to a stably lighting state. After the build-up time interval, the drive device is controlled to feed a second current to the discharge lamp. The first current is greater than the second current.
