    • A walk-behind, self-propelled lawn mower having a variable speed drive transmission responsive to operator applied forces. The drive transmission is mounted on a frame and comprises gearing operatively connected to an engine and a drive shaft for transmitting forces from the engine to the shaft. A clutching structure including a frictional coupling is coactable with an element of the gearing selectively to provide force transmission to the drive shaft. An actuator structure is controllably connected to the clutching structure and responsive to operator applied forces for controlling the speed at which the lawn mower traverses along a ground surface and to vary the speed proportionally to operator applied forces. The lawn mower also includes a handle pivotally connected to the frame and operatively connected to the actuator structure. The handle is adapted to pivot in response to the operator applied forces.
    • 具有响应于操作者施加力的变速驱动传动装置的步行式自行式割草机。 驱动传动装置安装在框架上,并且包括可操作地连接到发动机的传动装置和用于将力从发动机传递到轴的驱动轴。 包括摩擦联接器的夹紧结构选择性地与齿轮的元件共同作用以向驱动轴提供力传递。 致动器结构可控制地连接到离合器结构,并且响应于操作者施加的力来控制割草机沿着地面穿过的速度,并且与操作者施加的力成正比地改变速度。 割草机还包括枢转地连接到框架并可操作地连接到致动器结构的手柄。 手柄适于响应于操作者施加的力而枢转。

    • A bistable nematic liquid crystal display cell is electrically switched between topologically equivalent, asymmetric horizontal states. Switching is initiated by application of a symmetry breaking field such as a DC electric field of a predetermined polarity. An AC electric potential is then applied across the cell to complete the switching cycle and maintain the state. The cell includes upper and lower parallel substrates, upper and lower topographically textured tilt alignment surfaces on the corresponding substrates, and nematic liquid crystal material between the substrates. In an active region of the cell, the tilt alignment surfaces form an equal reverse tilt boundary condition. In an isolation region surrounding the active region of the cell, the tilt alignment surfaces are formed to have a parallel tilt boundary condition.
    • 双稳向列型液晶显示单元在拓扑等效的不对称水平状态之间电气切换。 通过施加诸如预定极性的DC电场的对称断裂场来开始切换。 然后将AC电势施加在电池单元上以完成开关周期并保持该状态。 电池包括上和下平行衬底,相应衬底上的上,下地形纹理的倾斜对准表面以及衬底之间的向列型液晶材料。 在电池的有源区域中,倾斜对准表面形成相等的反向倾斜边界条件。 在围绕电池的有源区域的隔离区域中,倾斜对准表面形成为具有平行的倾斜边界条件。
