    • A capacitance type acceleration sensor includes a semiconductor substrate, a weight portion supported with the substrate through a spring portion, a movable electrode integrated with the weight portion, and a fixed electrode cantilevered with the substrate. The movable electrode is displaced along with a facing surface of the movable electrode in accordance with acceleration. The facing surface of the movable electrode faces a facing surface of the fixed electrode so as to provide a capacitor. The capacitance of the capacitor changes in accordance with a displacement of the movable electrode so that an outer circuit detects the acceleration as a capacitance change. Each facing surface of the movable and fixed electrodes has a concavity and convexity portion for increasing the capacitance change.

    • A flow meter is formed with a passage for introducing and carrying air to measure and has a sensing part disposed in the passage for measuring a flow rate of the air. A contraction part is formed on an inner surface of the passage so that the contraction part faces the sensing part. The contraction part narrows the flow of the air flowing near the sensing part. A flat surface of the contraction part is formed in parallel with the surface of the sensing part and at least upstream of the sensing part. Thus, collision of particles against the sensing part and adhesion of contaminants to the sensing pert are inhibited. Meanwhile, the flow rate of the air is measured stably and accurately.
    • 流量计形成有用于引入和携带空气进行测量的通道,并且具有设置在通道中的用于测量空气流量的感测部分。 收缩部分形成在通道的内表面上,使得收缩部分面向感测部分。 收缩部分使感应部分附近的空气流动变窄。 收缩部分的平坦表面形成为与感测部分的表面平行并且至少在感测部分的上游。 因此,抑制了颗粒与传感部分的碰撞以及污染物与传感污染物的粘附。 同时,稳定且准确地测量空气的流量。

    • A detector device of the present invention detects densities of components, such as gasoline and ethanol, contained in mixture fuel even when some water is included in the mixture fuel. The detector device includes a sensor having a pair or electrodes, an electronic device for calculating the densities and a memory device for storing permittivities of pure components including water measured beforehand. Alternating current having two different frequencies f1, f2 is applied to the pair of electrodes immersed in the mixture fuel to detect the permittivities of the mixture fuel under f1 and f2. The two frequencies, f1 and f2, are so chosen that the premittivities of gasoline and ethanol show no change between f1 and f2, while the permittivitiy of water shows a substantial difference between f1 and f2. The electronic device calculates the densities of the components based on permittivities of the mixture fuel detected by the sensor and those of components stored in the memory device.
    • 本发明的检测装置即使在混合燃料中含有一些水时也能够检测混合燃料中所含的汽油,乙醇等成分的浓度。 检测器装置包括具有一对或多个电极的传感器,用于计算密度的电子设备和用于存储包括预先测量的水的纯净组分的介电常数的存储器件。 将具有两个不同频率f1,f2的交流电施加到浸在混合燃料中的一对电极,以检测f1和f2下的混合燃料的介电常数。 两个频率f1和f2如此选择,使得汽油和乙醇的离子浓度在f1和f2之间不显示变化,而水的容许度在f1和f2之间显示出显着的差异。 电子设备基于由传感器检测到的混合物燃料的容量和存储在存储器件中的部件的密度来计算部件的密度。
