    • A vacuum interrupter comprises a vacuum vessel, at least a pair of electrical conductor rods extending from interior to exterior of the vacuum vessel, and at least a pair of separable composite electrodes respectively connected to the tip of the electrical conductor rods. Each of the composite electrodes has a main electrode, a parallel magnetic field generator for generating a parallel magnetic field which acts on an arc created when one main electrode is separated from the other, and a magnetic field suppressor of high electrical conductivity embedded in a central portion of the main electrode for partly cancelling the parallel magnetic field. In the vacuum interrupter, when the parallel magnetic field permeates through the magnetic field suppressor, eddy current flow is caused therein. A magnetic field due to the eddy current has a polarity opposite to that of the parallel magentic field and partly cancels the parallel magnetic field. Intensity of the parallel magnetic field then becomes smaller at the central portion than that at the other peripheral portion, and the arc tends to shift from the magnetic field suppressor to the outer peripheral portion, thereby preventing fusion damage of the magnetic field suppressor.
    • 真空断路器包括真空容器,至少一对从真空容器的内部延伸到外部的电导体棒,以及分别连接到电导体棒的尖端的至少一对可分离的复合电极。 每个复合电极具有主电极,平行磁场发生器,用于产生平行磁场,其作用于当一个主电极彼此分离时产生的电弧,以及嵌入中心的高导电性的磁场抑制器 用于部分地消除平行磁场的主电极部分。 在真空断路器中,当并联磁场渗透通过磁场抑制器时,在其中引起涡流。 由于涡流引起的磁场具有与平行磁场相反的极性,并且部分地抵消了平行磁场。 平行磁场的强度在中心部分的强度比其他周边部分的强度变小,电弧趋于从磁场抑制器向外周部分移动,从而防止磁场抑制器的熔断。

    • A liquid crystal display device includes a pair of substrates; a liquid crystal sealed between the substrates; plural pixel regions each having a first pixel electrode formed on one of the pair of substrates and a second pixel electrode separated from the first pixel electrode; a TFT having a source electrode which is electrically connected to the first pixel electrode; a control capacitance portion which has a control capacitance electrode electrically connected to the source electrode and opposed to at least part of the second pixel electrode via an insulating film, and which thereby establishes capacitive coupling between the source electrode and the second pixel electrode; linear projections formed on the other substrate; and apertures formed in the first and second pixel electrodes so as to occupy parts of overlap regions of the linear projections and the first and second pixel electrodes as viewed perpendicularly to the substrate surfaces, for controlling the positions of singular points of alignment vectors of the liquid crystal.
