摘要： A pressure transducer is disclosed comprising a pressure sensor portion having gage resistors in bridge formed on a thin diaphragm of a semiconductor substrate, and a power supply connected to the pressure sensor portion for driving the pressure sensor. The power supply includes a first current source for supplying a temperature-dependent current equivalent to the sum of a current almost proportional to the absolute temperature and a current independent of temperature, and a second current source for sinking the current almost proportional to the temperature characteristic of the gage resistors from the current of the first current source. A temperature compensation circuit is additionally provided to drive the bridge circuit by the difference between the temperature-dependent current and the current proportional to the temperature characteristic in a constant-current driving mode, and by a voltage proportional to the current difference when the output of the bridge circuit is connected to an amplifier whose gain is dependent on temperature.

摘要： A method and an apparatus for controlling the ignition timing for an internal combustion engine wherein whether the engine rotation is in acceleration or deceleration is detected and the magnitude of the acceleration or deceleration is detected. Each time an acceleration is detected, the ignition timing is shifted by a determined value in the same direction as that of the immediately preceding shifting, while each time a deceleration is detected, the ignition timing is shifted by a determined value in the direction reverse to that of the immediately preceding shifting, thus causing the ignition timing to approach to a situation where the engine is capable of producing its maximum torque under a given fuel supply.

摘要： The output of an oxygen concentration detector monitoring the conditions of exhaust gases from an internal-combustion engine is not a linear function of the concentration but varies widely. When feeding this output back to control the air-fuel ratio of the mixture being fed to the engine, the feed back system having the small time constant (small delay time in operation) becomes unstable due to the nonlinear output of the oxygen concentration detector. In order to stabilize the operation of the system the output of the oxygen concentration detector is input to compensating circuit which outputs the voltage being proportioned to the oxygen concentration of the exhaust gas and the output is used as the feedback signal.
