Abstract: A water valve assembly for bathroom faucets, comprising a water passage, an accommodating cavity and a flow diverting unit, whereby the flow pathway within a faucet can be adjusted. The accommodating cavity has a first cavity portion and a second cavity portion, the second cavity portion being connected to the water passage and provided with two water holes respectively connected to two water outlets. The flow diverting unit, being capable of rotating within the accommodating cavity, has a first end rotatably sealing the first cavity portion and a second end coupled to the outer body of the faucet by a limiting member, whereby the rotation of the flow diverting unit with respect to the accommodating cavity will be limited, and whereby a blocking member of the second end of the flow diverting unit can seal either of the water holes.

Abstract: A heating structure and its temperature control method having therein a heat generating line and a controller. The heat generating line includes a PTC element and a short circuit line serially connected having an insulating fusible layer separating them. When a user sets a heating temperature, electric current is conducted to heat the PTC element, alternative string wave signals input into an AC phase shaping circuit and an AC phase delay shaping circuit are converted into square wave signals; and by measuring with a microprocessor at a given time the phase shift between the two phase shaping circuits to control the switch of a trigger circuit, the PTC element can keep on heating or reduce its temperature to therefore keep the heat generating line at a predetermined working temperature. The structure is applicable to heat generating devices such as electric ovens and heating blankets etc.

Abstract: A valve includes a housing having two opposite juts and a bore and a projection, a plate having two curved oblong holes and a stem rotatably received in the bore of the housing, and a follower secured to the stem and having an extension for engaging with the projection of the housing. A base includes two inlets and two hubs aligned with the inlets, and an outlet, and an upper peripheral wall having two notches oppositely formed in an inner peripheral portion and each formed by an outer fence member. The juts of the housing are engageable into the notches of the base, and engageable into different notches of the base when the housing is rotated for 180 degrees relative to the base.

Abstract: A valve includes a housing having a projection, a plate having a stem rotatably received in the housing, a follower having an oblong orifice for receiving the stem, and defined by two parallel and symmetric engaging flat surfaces for engaging with the engaging flat surfaces of the stem and for allowing the follower to be anchored to and rotated in concert with the stem. The follower includes an extension for engaging with the projection. An engagement of the parallel and symmetric engaging flat surfaces of the stem and of the follower allows the follower to be engaged onto the stem after the stem has been rotated relative to the base, without rotating the follower relative to the base.

Abstract: A valve includes a housing having an inlet opening and an inlet orifice for receiving cold and hot water, a barrel slidably received in the housing and movable to control the cold and the hot water to flow into the housing. A stem is secured to the barrel and shortenable and lengthenable by different water temperature, to control the flowing of the cold and the hot water into the housing. A conduit is secured to the housing and a spring is received in the conduit, to bias against the stem. The conduit includes a passage to allow the water to flow in and out of the conduit, and to allow the spring to be quickly shortened and lengthened by different water temperature.

Abstract: A water distributor includes a housing having an inlet for receiving water, and having two or more openings formed in a peripheral wall, for coupling to two or more water outlet members. A valve member is rotatably received in the housing, and includes an orifice to receive the water, and a side aperture for selectively aligning with either of the openings of the housing, and to allow the water to flow out through either of the water outlet members. The valve member includes a spring-biased plug to engage with the housing. An anchor member may be attached to the housing, to rotatably retain the valve member in the housing.

Abstract: A shower device includes a conduit having a bore to slidably receive a lower portion of a tube, and to allow the tube to be adjusted up and down relative to the conduit. A shower head is attached to the tube and moved up and down together with the tube, and a control ferrule is attached to the conduit and the tube, and includes two or more sealing rings to make water tight seals between the conduit and the control ferrule, and between the tube and the control ferrule. The tube may be secured to a supporting surface with a bracket.

Abstract: A printed monopole antenna, having a spiral copper foil formed on a substrate of a printed circuit board is disclosed. The copper foil has two parallel conductive arms in communication with each other by at least another conductive arm extending across these two parallel conductive arms. The first one of the parallel conductive arms has one end reaching a lower edge of the substrate to serve as a signal feed point. The copper foil further has an adjust arm perpendicularly extending from an elongate edge of the second one of the parallel conductive arms towards the first one of the parallel conductive arm. The formation of the adjust arm expands the bandwidth of radio frequency of the antenna. Further, by changing the length of the adjust arm, the overall bandwidth of the antenna can be adjusted as required.

Abstract: In a pressing apparatus, a holding frame has a rear wall interconnecting and cooperating with opposite lateral walls so as to confine a receiving space for receiving a semiconductor device therein, and a bottom wall disposed at a bottom side of the receiving space. A positioning device, which is used to clamp the semiconductor device against the bottom wall, includes a press block unit disposed in the receiving space such that the semiconductor device is disposed between the press block unit and the bottom wall, two coupling blocks connected to opposite end portions of the press block unit, respectively, and two positioning pieces extending through screw holes in the coupling blocks, respectively, and operable to engage the lateral walls for retaining the press block unit at a desired position on the holding frame.

Abstract: A pressing kit for substrate or lead frame of a semiconductor packaging. The kit comprises a box body and a press block, wherein the box body is a hollow metallic body having a U-shaped lead board at the two lateral sides thereof. The bottom face of the inner side of the U-shaped lead board is provided with a blocking block for the holding of a bottom board. The pressing block is an elongated block body of similar length to the inner side of the box body, and the top face is provided with four pillar holes. The circular slot on the top of the pillar hole is inserted with a screw bolt from the top thereof, and a compression spring is placed at the wider recess at the bottom section.
