    摘要: In an acceleration sensor including a vibrator subject to a sliding vibration and a weight section connected to the vibrator and supported at a position different from the position of the center of gravity of an assembly of the vibrator and weight section, for detecting an angular moment about the support point, which is produced at the weight section by application of acceleration, as sliding vibration with the vibrator, the acceleration sensor includes a rectangular substrate having a plurality of electrodes electrically connected to the vibrator, a formation pattern of the plurality of electrodes is symmetrical about an axis parallel to at least one side of the substrate, and the plurality of electrodes have substantially equal thickness. Since the formation pattern of the electrodes on the substrate is symmetrical and the respective electrodes have substantially equal thickness, the vibrator that is bonded to this substrate does not incline and the detection sensitivity does not vary.

    摘要: A technique for enhancing the execution efficiency of simulation of a hybrid system. A continuous system simulator receives a request for evaluation of an event generating conditional expression for an event to be processed by a discrete system simulator, from the discrete system simulator. The event generating conditional expression is evaluated by referring to the value of a first variable describing a continuous system. Until evaluation of the event generating conditional expression indicates true, the continuous system simulator repeats simulation of advancing the current time by a step time interval and evaluation of the event generating conditional expression. When evaluation of the event generating conditional expression indicates true, the continuous system simulator sends current time data and the value of a second variable describing the continuous system which is referred to by the discrete simulator, to the discrete simulator.
