    • A semiconductor structure that may be a discrete capacitor, a Silicon On Insulator (SOI) Integrated Circuit (IC) including circuits with discrete such capacitors and/or decoupled by such discrete capacitors and an on-chip decoupling capacitor (decap). One capacitor plate may be a well (N-well or P-well) in a silicon bulk layer or a thickened portion of a surface silicon layer. The other capacitor plate may be doped polysilicon and separated from the first capacitor plate by capacitor dielectric, e.g., CVD or thermal oxide. Contacts to each of the capacitor plates directly connect and extend from the respective plates, such that direct contact is available from both plates.
    • 可以是分立电容器的半导体结构,包括具有离散这种电容器的电路和/或由这种分立电容器去耦合的片上绝缘体(SOI)集成电路(IC)和片上去耦电容器(decap))。 一个电容器板可以是硅本体层中的阱(N阱或P阱)或表面硅层的增厚部分。 另一个电容器板可以是掺杂多晶硅并且通过电容器电介质例如CVD或热氧化物与第一电容器板分离。 与每个电容器板的接触件从相应的板直接连接和延伸,使得从两个板可以直接接触。

    • The invention is directed to a tensioner for providing linear and angular movement of a drilling or production facility relative to a conduit or riser secured to the tensioner and to the wellhead in offshore operations. The tensioner compensates for vessel motion induced by wave action and heave and maintains a variable tension to the riser string alleviating the potential for compression and thus buckling or failure of the riser string. The tensioner of the present invention preferably includes at least one top load plate that facilitates easy and quick installation and removal of the tensioner from the rig floor of the vessel or platform. The tensioner also facilitates the placement of at least one piece of equipment disposed within the area formed by the tensioning cylinders. The tensioner may also include one or more pieces of equipment, e.g., a rotary table, integrally formed with the tensioner to further increase the ease and speed of installation and removal of the tensioner from the rig floor. Methods for installing and removing tensioners from the rig floor are also disclosed.
    • 本发明涉及一种张紧器,用于相对于在海上操作中固定到张紧器和井口的导管或立管提供钻孔或生产设备的线性和角运动。 张紧器补偿由波浪作用引起的船只运动并起伏,并且将提升管柱的可变张力保持在可调节的状态,减轻了压缩的可能性,从而降低了提升管柱的翘曲或失效。 本发明的张紧器优选地包括至少一个顶部负载板,其有助于从容器或平台的钻台底部容易且快速地安装和移除张紧器。 张紧器还有助于放置设置在由张紧缸形成的区域内的至少一件设备。 张紧器还可以包括与张紧器一体形成的一个或多个设备,例如旋转台,以进一步增加张紧器从钻台上的安装和移除的容易性和速度。 还公开了用于从钻台上安装和拆卸张紧器的方法。
