摘要： A method for measuring the flow rate of fluid such as liquified petroleum gas fuel for an automobile fuel. A signal of the fluid flow rate and a signal of the fluid temperature are produced by using the signals from an electric heater and a first, second, and third temperature-dependent resistors in a signal processing circuit. The produced signals are supplied to a computer circuit to carry out modification, linearization, and multiplication by a conversion constant for linearization which is corrected regarding temperature characteristic. The result of calculation in the computer circuit is displayed on a display device.

The selected voltage is integrated with respect to time by an integrating circuit. When the output from the integrating circuit has reached an upper limit voltage or a lower limit voltage, the above-mentioned binary switching signal which is an output signal of this signal converting apparatus is inverted by a comparator/inverter circuit.

摘要： In a fuel supply control apparatus for an internal-combustion engine, liquid fuel is vaporized and is supplied to a fuel gas passage leading to an intake air passage. The flow rate of the vaporized fuel flowing through the fuel gas passage is detected, and the flow rate of the fuel is calculated in accordance with the load of the engine. As a result, feedback control of the fuel to be supplied to the engine is carried out so that the detected flow rate of the vaporized fuel is close to the calculated flow rate of the fuel.

摘要： Two closed circuits respectively are each comprised of a primary coil of a transformer for plug ignition, a transistor, a diode, a resistor and a common power source. When one of the transistors is conductive during the ignition period, the current in the related closed circuit increases. When the increased current appearing across the associated resistor exceeds a reference value, the associated comparator renders the conducting transistor nonconductive while it renders the other nonconductive transistor conductive, whereby the transistors continues a push-pull operation at given periods. Each diode is inserted either between the associated primary coil and the associated transistor or between the associated primary coil and the common power source.
