摘要： A sensing device, such as an angular speed detecting device, includes a vibrator for improving detection precision. The vibrator is displaceably supported on a substrate and is vibrated in the direction of an X-axis by driving electrodes. Detecting electrodes detect vibrations of the vibrator in the direction of a Y-axis caused by a Coriolis' force resulting from the angular speed occurring about a Z-axis. Each of the driving and detecting electrodes includes a movable electrode that is connected to the vibrator and that is displaced together therewith on the substrate and a fixed electrode fixed onto the substrate in such a manner as to face the movable electrode. By equalizing conductors connected to fixed electrodes of the driving electrodes and conductors connected to fixed electrodes of the detecting electrodes in length, width, and thickness, respectively, one electrical characteristic is set for those of the wiring portions which function in the same manner.

摘要： The present invention controls ignition timing appropriately while an increment correction of the fuel injection amount is implemented. A control device of the invention determines a retard angle based on a difference between a prior increment factor, which is determined prior to an actual increment of the fuel injection amount in response to loading of the engine and an OTP fuel increment correction factor for determining the actual increment of the fuel injection amount. The engine load may be determined by intake air quality and rotating speed. When the increment correction is delayed for a fixed time period, the structure of the invention effectively prevents the ignition timing from being retarded excessively due to frequent knocking at the beginning of the delay time. This accordingly prevents the ignition timing from being maintained in the retarding condition to undesirably lower the power of the engine when the delay time has elapsed and an actual increment of the fuel injection amount has been executed. In the ignition timing control of the invention, an increase in retard angle immediately affects the ignition timing control while a decrease in retard angle slowly affects the ignition timing control. This allows the ignition timing to be controlled appropriately without undesirable delay.
摘要翻译：本发明在实施燃料喷射量的增量校正的同时适当地控制点火正时。本发明的控制装置基于在响应于发动机负载的燃料喷射量的实际增量之前确定的先前增加因子与用于确定发动机的OTP燃料增量校正因子之间的差异来确定延迟角燃料喷射量的实际增量。发动机负载可以通过进气质量和转速确定。当增量校正被延迟固定时间段时，本发明的结构有效地防止了点火正时因延迟时间开始时的频繁敲击而过度延迟。因此，当延迟时间已经过去并且执行了燃料喷射量的实际增量时，这样可以防止点火正时维持在延迟状态，从而不期望地降低发动机的功率。在本发明的点火正时控制中，延迟角的增加立即影响点火正时控制，而延迟角的减小缓慢地影响点火正时控制。这允许适当地控制点火正时而没有不期望的延迟。
