    • A voltage-controlled oscillator (VCO) comprising an odd number of delay stage circuits. Each delay stage circuit operates between supply voltages VDD and VSS (VDD>VSS) and comprises (1) an input node, (2) an output node, (3) an inverting circuit, and (4) an electric discharge path coupling the output node to VSS. The electric discharge path includes a switch circuit and a resistance adjusting circuit electrically coupled in series between the output node and VSS. In response to an input signal rising at the input node, the inverting circuit decreases an output signal at the output node, and the electric discharge path opens to help pull the output signal down faster. In response to an input signal falling at the input node, the inverting circuit increases the output signal at the output node, and the electric discharge path closes to minimize its own effect.
    • 包括奇数个延迟级电路的压控振荡器(VCO)。 每个延迟级电路在电源电压VDD和VSS(VDD> VSS)之间工作,并且包括(1)输入节点,(2)输出节点,(3)反相电路,以及(4)将输出 节点到VSS。 放电路径包括在输出节点和VSS之间串联电耦合的开关电路和电阻调节电路。 响应于在输入节点处上升的输入信号,反相电路减小输出节点处的输出信号,并且放电路径打开以帮助较快地拉出输出信号。 响应于在输入节点处的输入信号,反相电路增加输出节点处的输出信号,并且放电路径关闭以最小化其自身的效果。

    • A fluid coupling capable of indicating proper tightening includes a fitting body having a flared end with a back side. The fitting body also includes an indicator spaced a predetermined distance away from the back side. A threaded nut is positioned around the fitting body adjacent the flared end and includes a back end and a shoulder portion spaced away a predetermined distance therefrom. The shoulder portion is concentrically aligned with the back side of the flared end. The fluid fitting also includes a belleville washer(s) positioned around the fitting body adjacent the back side of the flared end, which is (are) compressed upon threading and torquing of the nut onto the threaded end of a male fitting. When a predetermined amount of torque has been applied to the nut, the indicator is visible adjacent the back end of the nut.
    • 能够指示适当紧固的流体联轴器包括具有背侧的扩口端的配合体。 装配体还包括与背面隔开预定距离的指示器。 螺纹螺母围绕配件主体定位在靠近喇叭口端部处,并且包括后端和与之隔开预定距离的肩部。 肩部与喇叭口端的后侧同心对准。 流体配件还包括围绕配件主体定位的靠近喇叭形端部的后侧的贝氏垫圈,该螺纹垫圈在将螺母螺纹拧紧并扭转到阳配件的螺纹端上时被压缩。 当预定量的扭矩已经施加到螺母时,指示器在螺母的后端附近是可见的。
