    • A downhole valve has a closure device (e.g., one or more flappers) for closing off the valve. A no-go actuation mechanism protects the flappers from damage. When the flappers are closed, the mechanism prevents a tool from passing into the valve and causing damage to the flappers. Yet, the mechanism may open the valve's flappers when the tool string is forced into the valve. When the valve has successfully opened, then the mechanism moves out of the way of the toolstring so it can pass through the valve. For the mechanically operated valves, operators use a shifting profile in the valve only in the upward direction to return the valve to the closed position. For hydraulic actuated valves, hydraulic pressure may be used or exhausted, depending on the design, to allow the flappers to go closed. Once the flappers have closed, the no-go mechanism is once again realized.
    • 井下阀具有用于关闭阀的闭合装置(例如,一个或多个挡板)。 不起动致动机构保护挡板免受损坏。 当盖板关闭时,该机构防止工具进入阀门并导致刮板损坏。 然而,当工具串被迫进入阀门时,该机构可以打开阀的挡板。 当阀门成功打开时,机构就会移动到工具串的方式,使其能够通过阀门。 对于机械操作的阀门,操作人员仅在向上的方向上使用阀门中的换档曲线,使阀门返回关闭位置。 对于液压致动阀,可以根据设计使用或排出液压,以允许挡板关闭。 一旦挡板关闭,再次实现了脱扣机构。

    • An apparatus and method for a fast recovery rectifier structure. Specifically, the structure includes a substrate of a first dopant. A first epitaxial layer lightly doped with the first dopant is coupled to the substrate. A first metallization layer is coupled to the first epitaxial layer. A plurality of trenches is recessed into the first epitaxial layer, each of which is coupled to the metallization layer. The device also includes a plurality of wells each doped with a second dopant type, wherein each well is formed beneath and adjacent to a corresponding trench. A plurality of oxide layers is formed on walls and a bottom of a corresponding trench. A plurality of channel regions doped with the first dopant is formed within the first epitaxial layer between two corresponding wells. Each of the plurality of channel regions is more highly doped with the first dopant than the first epitaxial layer.
