    摘要： The invention relates to an engine electronic control unit (1) that is inserted through a through hole provided in an intake pipe and mounted in an intake air passage (3) in a direction substantially perpendicularly with respect to a plane of the intake pipe forming the intake air passage (3). This unit is then secured to the intake pipe using a fixing flange (22) provided at a connector portion (21). A fixing rail (5) is protruded inside the intake pipe and leading edges of a metal base (12) and a metal cover (13) of the unit are inserted into this rail, thereby securing in position an end opposite to a side of the connector portion (21) of the unit. This realizes an engine electronic control unit offering an outstanding heat radiation performance and vibration resistance, without having to provide special heat radiating parts or without involving an increase in an intake air resistance within the intake air passage (3). By using such an engine electronic control unit, it is possible to provide a low-cost, compact engine air intake system.

    摘要： In order to ensures a stable reduction of noise level at all times, in the steps of switching input voltage with a switching element (10), smoothing the voltage of rectangular wave obtained by switching with a reactor L and capacitor Cf and outputting it, the voltage obtained by dividing the output voltage is compared with the sawtooth wave output from a sawtooth wave generator (14) by a comparator (12). When the switching signal in response to the result of this comparison is applied to the switching element (10), the counter (16) is actuated synchronously with the vertex of the sawtooth wave to perform opening/closing operation of the switch SW1. The time constant of the time constant circuit comprising a R0 and C is adjusted according to whether a resistor R1 is present or not, and the signals of frequencies f1 and f2 coming out of the sawtooth wave generator (14) are sequentially switched to be sent to the comparator (12). The peak of the switching noise is diffused in the frequency range by sequential selection of switching frequencies, and noise level is reduced by diffusion of noise energy.

    摘要： A digital pulse processing device is capable of selecting precision. The digital pulse processing device includes a counter group for counting pulses output from a pulse output device, the counter group having a plurality of counters 110 and 111 that can be separated from and coupled with each other, a mode control circuit 129 for instructing separation and coupling of the counters 110 and 111, and a control circuit 116 for separating and coupling the counters 110 and 111 in accordance with the instruction of the mode control circuit 129. An overflow condition of the timer 119 is detected using an overflow flag. Detection of an overflow is conducted by setting the flag when an overflow condition has occurred twice or more. The flag is reset by rewriting the state of the flag by a software. An overflow condition which has occurred for the first time is detected in the conventional manner and is treated as carry or borrow. A register 128 is provided to hold the value of the timer 119 when a microcomputer reads in the counter 111. In this way, even when ΔA(i) = 0, speed detection operation can be executed using the value of the counter 111 obtained synchronously with the counting of the counter 110.
