摘要： A first temperature dependent resistor, an electric heater and a second temperature dependent resistor are arranged in this order within and from the downstream to the upstream of a pipe in which flows a gas whose flow rate is to be measured. A bridge circuit is formed by the first and second temperature dependent resistors along with first and second reference resistors. In response to the output of the bridge circuit, a measuring circuit regulates the supply of power to the electric heater and generates a signal indicative of the flow rate of the gas. Each of the first and second reference resistors is in the form of a film resistor formed on an insulating base. The insulating base having the film resistors formed thereon is placed for example in the flow of the gas to be measured. Each of the first and second temperature dependent resistors and the electric heater includes a resistance wire of a platinum alloy containing platinum and a predetermined proportion of another metal such as nickel, rhodium, iridium, palladium or ruthenium.

摘要： A first temperature dependent resistor and a second temperature dependent resistor are disposed within a single gas passage defined by a branch pipe extending into a conduit for a gas whose flow rate is to be measured. An electric heater is located between these temperature dependent resistors and is heated for the purpose of measurement of the flow rate of the gas. A first reference resistor and a second reference resistor constitute a bridge circuit together with the first and second temperature dependent resistors, and the difference between the potentials at the terminals of the bridge circuit is amplified by a first differential amplifier circuit. The difference between the output voltage of the first differential amplifier circuit and a predetermined reference voltage is then amplified by a second differential amplifier circuit. The output of the second differential amplifier circuit is amplified by a power amplifier, and the output of the power amplifier is used to control the current or voltage supplied to the electric heater.

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： An electronically controlled ignition system for internal combustion engines. Reference position detecting means generates reference signals and angular position detecting means generates angular signals indicative of the angular positions of an engine at every predetermined angle of its rotation. Computing means responsive to engine operating condition parameters computers a proper ignition coil energization starting timing data and a proper ignition coil de-energizing timing data. An ignition coil control circuit comprising latch circuits, comparator circuits and counting means converts the ignition coil energization starting timing data and the ignition coil de-energization timing data into pulses having a corresponding pulse width with respect to the rotational angle of the engine to supply an ignition coil energization starting timing signal and an ignition coil de-energizing timing signal to said ignition coil. The computations of the energization starting timing and de-energization timing are initiated in response to the reference signal and the energization starting timing signal, respectively, so that the energization starting timing data is computed by using the de-energization timing data computed in the preceding computation cycle and that the ignition coil control circuit is simplified in circuit construction.
