    • A pneumatic pressure responsive valve assembly includes a housing, a diaphragm piston including a diaphragm member and a piston member, the diaphragm member having an outer periphery secured to the housing and an inner periphery secured to the piston member, two pneumatic chambers defined by the diaphragm piston within the housing, one of the chambers selectively receiving both of the fluid pressures which are higher and lower than those within the other of the chambers, the diaphragm member having a curvature which expands towards either of the chambers, an expanding portion formed on either of the housing or the piston member and corresponding to the configuration of the curvature of the diaphragm member to thereby prevent the curvature of the diaphragm member from turning over, and a valve member for cooperation with movement of the piston member.
    • 气动压力响应阀组件包括壳体,包括隔膜构件和活塞构件的隔膜活塞,隔膜构件具有固定到壳体的外周边和固定到活塞构件的内周,由隔膜限定的两个气动室 活塞在壳体内,其中一个腔室选择性地接收两个流体压力,这两个流体压力高于和低于另一个腔室内的流体压力,隔膜部件具有向任一腔室扩张的曲率, 并且对应于隔膜构件的曲率的构造,从而防止隔膜构件的曲率翻转,以及用于与活塞构件的运动配合的阀构件。

    • An angular rate sensor comprises an oscillator excited for oscillation in x-direction, a movable electrode disposed in opposing relationship with a stationary electrode along z-direction, and a movable electrode support for transmitting the oscillation of the oscillator in the z-direction to the movable electrode while interrupting the transmission of the oscillation in the x-direction, and is formed by a micromachining operation. The movable electrode support includes an oscillator support beam continuing from the oscillator and extending in y-direction, an electrode support beam continuing from the oscillator support beam and extending in the x-direction, and a connector stem extending in the x-direction form the electrode support beam and connected to the movable electrode at a position which represents the center of gravity of the movable electrode. When a turning force about the y-axis is applied to the oscillator, Coriolis force is produced and causes the oscillator to undergo an elliptical motion, depicting an ellipse on an x-z plane. The electrode support beam and the oscillator support beam interrupt the x-component of the elliptical oscillation while transmitting only the z-component to the movable electrode. An electrical circuit connected to the movable electrode produces an electrical signal representing the z-component of the oscillation.
    • 角速率传感器包括被激励以在x方向上振荡的振荡器,沿z方向与固定电极相对设置的可动电极和用于将振荡器在z方向上的振荡传递到 可移动电极,同时中断x方向上的振荡传输,并通过微加工操作形成。 可移动电极支撑件包括从振荡器延伸并沿y方向延伸的振荡器支撑梁,从振荡器支撑梁延伸并沿x方向延伸的电极支撑梁,以及沿x方向延伸的连接器杆形成 电极支撑梁,并且在表示可动电极的重心的位置处连接到可动电极。 当围绕y轴的转动力被施加到振荡器时,产生科里奥利力,并使振荡器经历椭圆运动,描绘在x-z平面上的椭圆形。 电极支撑梁和振荡器支撑梁中断了椭圆振荡的x分量,同时仅将z分量传输到可动电极。 连接到可移动电极的电路产生表示振荡的z分量的电信号。
