Patent number: 6131595Abstract: 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.Type: GrantFiled: March 1, 1999Date of Patent: October 17, 2000Inventor: William H.

Patent number: 5486772Abstract: 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.Type: GrantFiled: June 30, 1994Date of Patent: January 23, 1996Assignee: Siliconix IncorporationInventors: Fwu-Iuan Hshieh, Calvin K.

Patent number: 4248994Abstract: 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.Type: GrantFiled: June 14, 1979Date of Patent: February 3, 1981Assignee: Fabridyne, Inc.Inventor: William H.
