    • A pressure-changing device of a leak check system for a fuel vapor treatment system has a pressure chamber formed in a peripheral space of a communicating path connecting a pump with an electromagnetic valve, the pressure chamber being deviated from flow delivered by the pump. The electromagnetic valve is opened to connect the communicating path with a canister. Then, a purge valve is closed and the pump is turned on to change pressure in a fuel vapor path. A pressure sensor attached on a side wall of the pressure chamber detects pressure in the communicating path to determine pressure in the fuel vapor path. The leak check system judges existence of leak in the fuel vapor treatment system from pressure in the fuel vapor path.

    • A noise suppressor for reducing propagation of a floor impact noise generated in an upper story to a lower story in a multi-storied building is disclosed. A reference sensor set at a position between a floor of the upper story and a ceiling of the lower story detects a floor impact noise generated in the upper story and converts the noise to an electric signal. This signal is computed and processed by a control unit and transmitted to a speaker located at a position lower than the reference sensor. The speaker emitts a sound wave interfering the floor impact noise to eliminate the noise. The noise not having been suppressed is detected by an error sensor and processed together with the noise detected by the reference sensor by the control unit, thus a sound wave to be emitted from the speaker is corrected appropriately.
    • 公开了一种用于减少在多层建筑物中的上层故障产生的地板撞击噪声向下层故障的传播的噪声抑制器。 设置在上层楼层和下层楼层天花板之间的位置的参考传感器检测上层楼层产生的楼层撞击噪声,并将噪声转换成电信号。 该信号由控制单元计算和处理,并被发送到位于低于参考传感器的位置的扬声器。 扬声器发出声波干扰地板撞击噪声,以消除噪音。 没有被抑制的噪声由误差传感器检测,并且由控制单元与基准传感器检测到的噪声一起处理,因此从扬声器发射的声波被适当地校正。
