    • For an exhaust analyzer, the factors causing turbulence and mixing of the sample gas are removed from the sample gas-introducing pipe in order to introduce the sample gas into the analyzer cell under laminar conditions. Further, the indicated changes resulting from the fluctuations of sample gas pressure within the analysis cell of such a construction are compensated. As a result, the sample gas can be quantitatively analyzed with a high rate of response under the condition that the influences caused by the fluctuations of the sample gas pressure are reduced.The sample gas is introduced into the cell-type gas analyzer from the sample gas source through a gas-introducing pipe under laminar conditions. A pressure sensor detects the changes in pressure within the cell of the gas analyzer, and in response to the pressure sensed by the pressure sensor a compensating means compensates for the erroneous indication of gas characteristics generated by the analysis cell as a result of the fluctuations of sample gas pressure therein.
    • 对于排气分析器,从样品气体导入管中除去引起湍流和样品气体混合的因素,以便在层流条件下将样品气体引入分析器单元。 此外,由这种结构的分析单元内的样品气体压力的波动引起的指示的变化被补偿。 结果,在由于样品气体压力的波动引起的影响减小的条件下,能够以高响应率对样品气体进行定量分析。 样品气体在层流条件下通过气体导入管从样品气体源引入电池型气体分析仪。 压力传感器检测气体分析器的电池内的压力变化,并且响应于压力传感器感测到的压力,补偿装置补偿由于分析电池产生的气体特性的错误指示,这是由于波动 样气压力。

    • Wheel cylinders supplied with oil pressure from a master cylinder are respectively provided in brake mechanism provided in wheels of a vehicle. The wheel cylinder has a brake piston provided to form a first fluid chamber to supply oil pressure from the master cylinder, and a brake piston driven by the oil pressure of the first fluid chamber. The wheel cylinder has a piston mechanism formed by laminating thin plate shaped piezoelectric elements, and the piston mechanism is controlled to be expanded or contracted by controlling the voltage applied to the piezoelectric elements to vary the volume of the first fluid chamber. Cut-off valves are provided in passages for supplying the oil pressure from the master cylinder to the wheel cylinders, a check valve for allowing only the work oil to flow from the master cylinder to the wheel cylinder in parallel with the cut-off valve to control to expand the piston in the state the oil pressure is generated from the master cylinder and the cut-off valve is closed to control to further strengthen the oil pressure in the first fluid chamber.
    • 提供有来自主缸的油压的轮缸分别设置在设置在车辆的车轮中的制动机构中。 轮缸具有制动活塞,该制动活塞设置成形成第一流体室,以从主缸提供油压,以及由第一流体室的油压驱动的制动活塞。 轮缸具有通过层叠薄板状压电元件而形成的活塞机构,并且通过控制施加到压电元件的电压来改变第一流体室的体积来控制活塞机构的膨胀或收缩。 截止阀设置在用于将主缸的油压供给到轮缸的通道中,止回阀仅允许工作油从截止阀平行地从主缸流到轮缸, 控制在从主缸产生油压的状态下膨胀活塞,并且截止阀被关闭以控制以进一步增强第一流体室中的油压。
