    • A self-latching solenoid valve assembly including a valve body having a pressurized air supply inlet port for communicating with a source of pressurized air and at least one cylinder port. A valve member is supported in the valve body so as to be movable between predetermined positions to selectively direct pressurized air from the inlet port to at least one cylinder port. A biasing member is employed to move the valve member in one direction and a solenoid assembly is used to move the valve member in an opposite direction. The solenoid assembly includes a housing with a solenoid coil supported therein and a fixed ferromagnetic pole piece having a passage extending therethrough with a pushpin movably supported in the passage. A ferromagnetic latch is also supported by the housing and spaced from the pole piece. A permanent magnet is disposed between the latch and the pole piece. The magnet is movable toward the pole piece under the influence of an electromagnetic flux generated by a pulse of current generated through the coil in one direction thereby driving the permanent magnet against the pushpin to move the valve member to one predetermined position. In addition, the permanent magnet is also movable away from the pole piece and toward the latch under the influence of an electromagnetic flux generated by a pulse of current flowing through the coil in an opposite direction. When this occurs, the biasing member moves the valve member to another predetermined position. A control circuit for changing the direction of the current through the coil is also disclosed.
    • 一种自锁式电磁阀组件,包括具有用于与加压空气源和至少一个气缸端口连通的加压空气供应入口的阀体。 阀构件被支撑在阀体中,以便能够在预定位置之间移动,以将加压空气从入口选择性地引导到至少一个气缸端口。 使用偏置构件沿一个方向移动阀构件,并且使用螺线管组件沿相反方向移动阀构件。 螺线管组件包括具有支撑在其中的螺线管线圈的壳体和固定的铁磁极片,其具有通过其延伸穿过的通道,其中可动地支撑在通道中的图钉。 铁磁闩锁也由壳体支撑并且与极片间隔开。 永磁体设置在闩锁和极片之间。 磁体可以在由一个方向上通过线圈产生的电流脉冲产生的电磁通量的影响下移动,从而将永磁体驱动到图钉上,以将阀构件移动到一个预定位置。 此外,永磁体也可以在由相反方向流过线圈的电流脉冲产生的电磁通量的影响下移动离开极片并朝向闩锁移动。 当这种情况发生时,偏置构件将阀构件移动到另一预定位置。 还公开了一种改变电流通过线圈的方向的控制电路。

    • Optical article having a substrate with first and second surfaces and with a conductive antireflection coating disposed on the first surface. The conductive antireflection coating is comprised of at least one layer of a low index material carried by said first surface and a thin transparent conducting layer of a material having a high index of refraction carried by the layer of material having a low index of refraction. The conducting layer provides an exposed surface to which the direct electrical contact can be made. The conducting layer has an optical thickness ranging from 1.0 to 30.0 nanometers. The layer of material having a low index of refraction has its design thickness reduced to compensate for the thickness of the conducting layer whereby the conducting layer does not seriously degrade the optical performance of the coating over that which could be obtained without the use of the conducting layer.

    • A circuit for controlling a valve assembly in applications where electrical isolation of the two control signal supply lines is required to prevent damage of control circuits caused by a reverse polarity feedback signal or other transient signal. The circuit includes a solenoid having a coil. The coil has a first end and a second end. The circuit also includes a first switching circuit electrically connected to the first and second ends of the coil to allow current to pass therethrough in a first direction to move a permanent magnet against a pushpin a first axial direction. The circuit further includes a second switching circuit electrically connected to the first and second ends of the coil to allow a current to pass therethrough in a second direction to move the permanent magnet away from the pushpin in a second axial direction. Further, when either switching circuit is allowing current to flow through the coil, it electrically isolates one negative control source from the other. The use of a pair of switching circuits electrically connected to the coil results in a relatively low voltage drop across the circuit.
    • 在需要两个控制信号电源线的电隔离以防止由反极性反馈信号或其它瞬态信号引起的控制电路损坏的应用中,用于控制阀组件的电路。 该电路包括具有线圈的螺线管。 线圈具有第一端和第二端。 电路还包括电连接到线圈的第一和第二端的第一开关电路,以允许电流沿第一方向通过,以使第一轴向方向上的永久磁体移动到图钉上。 电路还包括电连接到线圈的第一和第二端的第二开关电路,以允许电流沿第二方向通过,以使永磁体在第二轴向方向上从图钉移开。 此外,当任一开关电路允许电流流过线圈时,它将一个负控制源与另一个负控制源电隔离。 电连接到线圈的一对开关电路的使用导致跨越电路的相对低的压降。
