    • A semiconductor device embodiment includes a substrate, an active gate trench in the substrate, and an asymmetric trench in the substrate. The asymmetric trench has a first trench wall and a second trench wall, the first trench wall is lined with oxide having a first thickness, and the second trench wall is lined with oxide having a second thickness that is different from the first thickness. Another semiconductor device embodiment includes a substrate, an active gate trench in the substrate; and a source polysilicon pickup trench in the substrate. The source polysilicon pickup trench includes a polysilicon electrode, and top surface of the polysilicon electrode is below a bottom of a body region. Another semiconductor device includes a substrate, an active gate trench in the substrate, the active gate trench has a first top gate electrode and a first bottom source electrode, and a gate runner trench comprising a second top gate electrode and a second bottom source electrode. The second top gate electrode is narrower than the second bottom source electrode.

    • A compact air pump and valve package includes pump and valve assemblies integral with a pressure housing defining inlet ports and a plurality of fittings for connecting air lines to an interior of the pressure housing. The linear diaphragm pump assembly has a permanent magnetic shuttle mounting two diaphragms reciprocated by an electromagnet. The valve assembly has a plurality of solenoid valves disposed within the pressure housing, each solenoid valve being operable to control flow into or out of the pressure housing through an associated one of the plurality of fittings. Thus, no tubes or hoses are required to transfer air from the pump assembly to the valves. The housing has special mounts to isolate vibration arising from movement of the shuttle.
    • 紧凑的空气泵和阀包装包括泵和阀组件,其与限定入口的压力壳体和用于将空气管线连接到压力壳体的内部的多个配件成一体。 线性隔膜泵组件具有安装由电磁体往复运动的两个隔膜的永久磁性梭。 阀组件具有设置在压力壳体内的多个电磁阀,每个电磁阀可操作以通过多个配件中的相关联的一个来控制流入或流出压力壳体的流体。 因此,不需要管或软管将空气从泵组件传送到阀。 外壳具有特殊的安装座,用于隔离由梭子移动引起的振动。
