In the thermal process air flow meter according to the invention first, second and third electrode terminals are arranged on the same surface at one end of a substrate. A first exothermic resistor is connected between the first and second terminals, and a second exothermic resistor is connected between the second and third terminals, with the first exothermic resistor on a front surface of a substrate and the second exothermic resistor on the opposite (back) surface. The substrate may also carry the semiconductor elements of an electronic circuit used to analyze electric signals from the terminals. In a preferred embodiment of the invention, the substrate is mounted at an incline relative to the direction of unobstructed air flow in the air passage.

The air meter forming part of the air intake passage of the engine is equipped with an electronic circuit for measuring the rate of intake air and a memory for storing data pertaining to actual air flow rate versus output characteristics of the air meter or correction data for calculation of air flow rate. The engine control unit digitally calculates actual air flow rate to be used for determination of the amount of fuel to be supplied from a signal output from the air meter with reference to the air flow rate versus output characteristics of the air meter or air flow correction data fetched from the memory provided on the air meter body.

The present invention relates to a method and an apparatus for controlling a car equipped with an automatic transmission having a lockup clutch. According to the control method of the present invention, when the lockup clutch is in the lockup state, a variation of a generated torque is detected. When the range of the torque variation detected exceeds a predetermined value, an engine torque is reduced by controlling the engine, and the automatic transmission is controlled to compensate for a reduction of the driving torque due to a reduction of the engine torque. Thus, the speed change ratio is changed to the low gear side. The control unit of the present invention includes a unit for controlling an output torque of an engine according to a command value, a unit for changing the transmission ratio of the automatic transmission, a unit for detecting a variation of the engine torque, a unit for deciding a target driving torque, a unit for reducing a torque command value when the range of a detected variation of the torque has exceeded a predetermined value when the lockup clutch was in the lockup state, and a unit for deciding a transmission ratio at which the reduction of the driving torque due to the reduction of the engine torque is compensated for.

This invention proposes methods of effectively forming a metal-backed layer and an anode using a metal film transferring sheet in which micro-holes are formed. that is, the metal film transferring sheet is structured by forming a metal film on a mold-releasable, highly characteristic sheet. Then, the metal film having micro-holes of the metal film transferring sheet is transferred onto a phosphor screen. Or, on the metal film of the above-mentioned metal film transferring sheet, is formed a phosphor screen and the metal film, the phosphor screen, etc. are all transferred onto a face plate form an anode of a cathode-ray tube. Then the methods proposed by this invention are applied for making phosphor products of, for example, a cathode-ray tube or a plasma display. According to these methods, there is no need to use a large-scaled manufacturing facility and high quality, low cost products can be obtainable.

Disclosed is an air flow metering apparatus for an internal combustion engine of the type in which heating current supply to a hot-wire air flow meter for detection of engine suction air flow rate is made intermittent in synchronism with the rotation of the engine so as to directly generate a flow rate detection signal in the form of a pulse width signal. The apparatus comprises a computing circuit for generating a correction data by using variables including the rotation period of the engine and the opening rate of a suction air flow control elements, whereby an air flow data obtained from the pulse width signal is corrected on the basis of the correction data.

An air flow meter comprises an air velocity measuring resistor and a temperature compensating resistor and is installed in a bypass passage provided at an intake passage running through an air horn. The air velocity measuring resistor and the temperature compensating resistor are supported by lead wires whose portions exposed in the bypass passage have the same length. A cover forming the bypass passage is made of heat insulating synthetic resin material to prevent heats from being transmitted to the resistors.
