Abstract: A drinking water faucet capable of discharging waste water includes a main body, a valve base, a water control unit, a connecting tube and a securing nut. A receiving space that is through and downward is formed inside the main body, and a trough room and an air hole are formed at front portion of the receiving space, upper portion of which has a water outlet tube. A water outlet hole and water inlet tube are located at upper and lower portions of the valve base respectively, and a water control space and discharging portion are formed at front portion of the valve base. The reflux of waste water can be prevented to contaminate the filtering components by using the combination of the air hole, the discharging portion, a waste water import tube and a waste water export tube, so the drinking water becomes more clean and safe to drink.

Abstract: A unidirectional ceramic control valve includes a valve shell, a shaft, a ring unit, an upper ceramic piece, a lower ceramic piece, a valve base and at least one anti-leak ring. Lower section of the valve shell has two hook holes, and two notches are formed therebelow. A receiving trough is formed at an inner portion of lower section of the shaft to provide a space for the ring unit and the upper ceramic piece. The ring unit is a ring-shaped body with low friction coefficient, and when the ring unit is disposed between the shaft and upper ceramic piece, it prevents the shaft from directly contacting the upper ceramic piece to generate wear. The upper ceramic piece has two symmetric water holes, while the lower ceramic piece has two symmetric circulating holes. A first protruding unit and a second protruding unit are correspondingly formed at the valve base.

Abstract: A stent includes a stent body of a cylindrical configuration having outer and inner surfaces, a first coated layer coating at least the outer surface, and a second coated layer coating substantially completely over the first coated layer. The first coated layer is prepared of a first composition comprising a polymer and a vascular intimal hyperplasia inhibitor (preferably argatroban) of a kind, which does not inhibit proliferation of endothelial cells, the weight compositional ratio of the polymer to the inhibitor being within the range of 8:2 to 3:7. On the other hand, the second coated layer is prepared of a polymer alone or a second composition comprising a polymer and a drug, the weight compositional ratio of the drug to 80% by weight of the polymer being less than 20% by weight.

Abstract: The present invention provides a method of cutting a workpiece efficiently with high accuracy by utilizing tension adjusters to approximate tension in a wire in a wire saw to a predetermined target tension while effectively reducing only tension in a winder-side wire. The method comprises a forward-driven cutting step of cutting a workpiece while moving a wire forward, a first switching step of reversing a driving direction of the wire, a backward-driven cutting step of cutting the workpiece while moving the wire backward, and a second switching step of reversing a driving direction of the wire and returning to the forward-driven cutting step, the steps being repeated in this order. In both switching steps, only tension in a winder-side wire is reduced by tension manipulators. A reduction in target wire tension therefor is performed after completion of deceleration of the wire in each switching step.

Abstract: The present invention provides a wire saw which cuts a workpiece using a cutting wire and is capable of adjusting wire tension with high responsiveness. The wire saw includes first and second workpiece cutting units 1A and 1B. Each of the workpiece cutting units 1A and 1B includes a pair of guide rollers 10a and 10b around which a wire W is wound to form a workpiece-cutting wire group. The wire saw further includes a tension detector 18 which detects tension in the wire W between the workpiece cutting units 1A and 1B, and a control device 50. The control device 50 changes a rotational speed of the guide rollers 10a and 10b of at least one of the workpiece cutting units based on the tension detected by the tension detector 18 so as to keep the tension within an acceptable range.
