Abstract: In a multiple computer system in which a plurality of computer stations are connected for mutual data transfer via a common data bus, at least one computer station is provided with a fail safe facility which prevents disruption of the entire system due to malfunction of the computer station. The computer is preprogrammed to perform an input/output circuit diagnosis routine after power-up and before control program execution which causes the input/output circuit to output a coded pulse train signal. An abnormality detection circuit receives the coded pulse signal, converts it to a parallel-bit word, and compares the derived word to a stored, predetermined word. If the words match, the detection circuit causes a switching circuit to connect the computer to the common data bus; otherwise, the computer remains disconnected from the rest of the multiple computer system.

Abstract: A receiver is applied to optical communication using an optical pulse signal carrying data which is cyclically updated. The optical signal is converted to a corresponding electrical pulse signal. The data is extracted from the electrical signal. The extracted data from successive cycles are compared. In response to the result of comparison between the data, a determination is made as to the number of cycles in which the extracted data is at a given value. When the determined number of cycles reaches a variable preset number, a previously used data value is replaced by the given value. The amplitudes of the electrical signal pulses are compared with a reference level. The preset number is varied in accordance with the result of comparison between the pulse amplitudes and the reference level.

Abstract: A fuel cut-off control can prolong a period of time in which the engine speed is maintained at a range suitable for performing fuel cut-off and shorten a period of time in which the engine speed is in a fuel recovery range to minimize fuel consumption during engine deceleration. In a fuel cut-off control system in a fuel injection internal combustion engine with an automatic transmission, the fuel cut-off control system is responsive to a brake switch signal and an engine speed signal having a value above a fuel recovery threshold to decrease the value of a fuel cut-off threshold to again perform the fuel cut-off even in the normal fuel recovery range. Down shifting of a transmission gear is performed to increase engine speed to a level beyond the fuel cut-off threshold to prolong the fuel cut-off period.
