    摘要： A valve body is formed in two half sections which are secured together to define a water passage and to confine therebetween a thin gate valve blade for movement between a lower open position and an upper closed position. An actuator includes a flexible bellows sealed to the valve body above the passage and a top plate connected by a rod to the valve blade. The valve body and the bellows define an expandable fluid chamber connected by a bottom port or line to a drain line. The valve body is installed within a water supply line or a sewage drain line extending under a floor. In the event sewage water backs up within the drain line, air within the fluid chamber is compressed to expand the bellows upwardly for closing the valve. When the sewage water flows from the drain line, the air pressure reduces, and the bellows collapses and automatically returns the valve blade to its open position.

    摘要： Linear polymer resins composed of repeating hydrocarbon units linked together by ester or amide linkages are treated with a liquid or gaseous primary or secondary amine under thermal conditions which cause aminolysis of some of the linear linkages to produce polymer resins of reduced average molecular weight. The procedure is applicable to polyesters, such as polycarbonates and polyterephthalates, and to polyamides, such as nylon 66, nylon 6, nylon 11 and nylon 12. The process is particularly applicable to the recovery or recycling of throw-away bottles made of poly(ethylene terephthalate), hereinafter sometimes referred to as PET.

    摘要： A valve body is formed in two half sections which are secured together to define a drain line passage and to confine therebetween a thin gate valve blade for movement between a lower open position and an upper closed position. A cylindrical bellows is sealed to the valve body above the passage and is covered by circular top plate which is connected by a rod to the valve blade. The bellows defines an expandable fluid chamber connected by a bottom port to the drain line passage. The valve body is connected within a sewage drain line extending under a floor. In the event sewage water backs up within the drain line, air within the bellows is compressed to expand the bellows upwardly for closing the valve. When the sewage water drains from the drain line, the air pressure reduces, and the bellows collapses due to the weight of the top cover plate and automatically returns the valve blade downwardly to its open position.

    摘要： The present invention detects defects near the gate/trench-surface interface of trench transistors. Defects near this interface which cause long term reliability problems generally also result in charges being trapped near the interface. In accordance with one embodiment of the present invention, a negative voltage is applied to the gate of the trench transistor with its drain grounded and its source floating. A leakage current flowing between the gate and drain is measured as a function of the voltage applied to the gate. A transistor whose gate-drain leakage current exceeds a predetermined value at a specified gate voltage is deemed to be defective. In another embodiment of the present invention, the gate-drain leakage current is measured as described above and monitored over time. Charge accumulated near the gate-drain interface due to defects in the interface results in the gate-drain leakage current taking a longer period of time to fall off to its steady state value. Accordingly, if the leakage current of a particular trench transistor does not fall off to a predetermined value within a predetermined amount of time, the transistor is deemed to be defective. The minimum/maximum allowable gate-drain leakage current published in a data sheet for the trench transistor will provide consumers with additional assurance of the transistor's long term reliability.

    摘要翻译： 本发明检测沟槽晶体管的栅极/沟槽表面界面附近的缺陷。 导致长期可靠性问题的接口附近的缺陷通常也会导致接口附近收费。 根据本发明的一个实施例，负电压被施加到沟槽晶体管的栅极，其漏极接地并且其源极漂移。 根据施加到栅极的电压来测量在栅极和漏极之间流动的漏电流。 栅极漏极泄漏电流在指定的栅极电压下超过预定值的晶体管被​​认为是有缺陷的。 在本发明的另一个实施例中，如上所述测量栅 - 漏泄漏电流并随时间监测。 由于界面缺陷，在栅极 - 漏极接口附近积聚的电荷导致栅极 - 漏极泄漏电流需要更长的时间来降低到其稳定状态值。 因此，如果特定沟槽晶体管的泄漏电流在预定时间内没有下降到预定值，则认为晶体管有缺陷。 在沟槽晶体管的数据手册中公布的最小/最大允许栅 - 漏泄漏电流将为消费者提供晶体管长期可靠性的额外保证。

    摘要： Polyols containing at least one carboxamide group, --[NHC.dbd.O]--, in the polyol backbone impart to polyurethane resin-forming systems a unique combination of normal pot life and accelerated curing characteristics without sacrifice of final physical properties. Methods are given for preparation of such polyols which enable incorporation of a small, predetermined number of such carboxamide groups, not exceeding in number the hydroxyl functionality of the polyol, into each and every individual polyol molecule. The rapid-curing/property-development characteristics of derived polyurethane resin-forming systems are especially valuable in molding operations, where both mold cycle times and curing energy requirements are substantially reduced in comparison with conventional polyurethane resin-forming systems having similar final physical properties.
