摘要： A control signal is generated to actuate a solenoid-operated valve at an angle phase of rotation of an engine for cutting off a fuel supply to an engine cylinder. The control signal is determined by a reference angle signal produced at a reference angle of rotation of the engine, and a rotational angle signal produced for each crank angle. Rotational angle signals are counted which are produced after each reference angle signal before the angle phase is reached with any remainder angle smaller than the crank angle. The remainder angle is converted into a time based on an average number of r.p.m. of the engine at the time the conversion is effected. The control signal is issued upon elapse of the counted rotational angle signals and the converted time. A ratio of an instantaneous number of r.p.m. of the engine in the vicinity of the angle phase to an average number of r.p.m. of the engine is issued and used for correcting the time converted from the remainder angle with the ratio.

摘要： A coating quality measuring device has a pattern plate including one reference pattern portion having a larger pattern width and a plurality of strip pattern portions having different pattern widths which are smaller than that of the reference pattern portion and are decreased in order. The pattern plate is disposed opposite the coated surface. The pattern plate is reflected on the coated surface and a reflected image is formed on an image sensor. The image sensor successively outputs signals each corresponding to the lightness of each pattern portion on a line extending in a width direction of each pattern portion of the reflected image. A computing device calculates a difference between the peak value of the signal level of the output signal corresponding to each strip pattern portion in the reflected image and the signal level of the output signal corresponding to the ground portion, divides the calculated difference by the signal level of the output signal corresponding to the reference pattern portion and detects the pattern width of the strip pattern portion wherein the division value becomes not larger than a predetermined value, thereby to obtain the coating quality of the coated surface.

摘要： A system for controlling the air-fuel ratio in an internal combustion engine provided with a fuel injector. The system has an O.sub.2 sensor for issuing signals on two levels, one corresponding to a high air-fuel ratio, the other to a low air-fuel ratio, and a feedback control device responsive to the signal from the sensor. The feedback control calculates a correction factor for maintaining the air-fuel ratio to a desired value during steady operation and for indicating the deviation in the ratio from the desired value during transient conditions. This deviation is employed to generate a transient correction value which is selected to minimize the deviation during transient conditions.

摘要： In a method for controlling an internal combustion engine, a control signal is calculated according to a signal output from a rotational angle sensor in accordance with intervals of a predetermined crank angle .theta..sub.o within a range from a reference position to a position which does not exceed a retard angle .theta. and the deviation from the retard angle .theta. does not exceed the crank angle .theta..sub.o. An angle deviation .theta..sub.s obtained as a remainder of a dividing operation is converted into a corresponding time period in accordance with a current average rotational speed of the engine. The time is counted in accordance with clock signals having a predetermined period. An internal combustion engine control signal is produced in accordance with this time counting operation. At least two instantaneous rotational speed data obtained for each angular signal from a rotational angle sensor are stored. The angle deviation .theta..sub.s is corrected in accordance with an instantaneous rotational speed at the timing at which an internal combustion engine control signal is produced in accordance with the stored data.

摘要： A gas flow measuring apparatus for measuring intake air flow for an automobile engine having an electrical heater resistive member, and first and second temperature dependent resistive members. The first resistive member is located so as to be well influenced by heat from the heater resistive member, while the second resistive member is located so as to be little influenced by the same. The measuring apparatus measures a gas flow rate by using an output signal from a voltage dividing circuit as a series circuit of the first and second resistive members. In the gas flow measuring apparatus, a heater film resistive member is deposited on a first support member by an evaporation depositing or printing process, and is further covered with electric insulating material such as glass. The first resistive member is formed on the heat resistive member, with the insulating material interposing therebetween, whereby the close proximity of the heater resistive member to the first resistive member is realized, and the second resistive member is formed on a second support member.

摘要： Voltages at the diagonal points of a bridge circuit are amplified in an AC differential manner and half-wave rectified, which bridge circuit is formed of reference resistors and temperature dependent resistors located in front and rear of an electric heater in a duct through which air to be measured flows. The half-wave rectified voltage is sampled and held in synchronism with a control pulse signal from an oscillation circuit so that the sampling and holding operation is performed substantially at the center of the period during which the half-wave rectified voltage is produced. The held voltage and a constant reference voltage are amplified in a DC differential manner and then applied to a power amplifier circuit which controls a supply voltage to the electric heater. The voltage to be applied to the bridge circuit is an intermittent voltage which is produced by a chopper circuit.
