Abstract: A two-transistor PMOS memory cell includes a PMOS floating gate transistor sharing a drain/source P+ diffusion region with a PMOS select gate transistor. The shared drain/source diffusion region acts as a drain for the floating gate transistor and as a source to the select gate transistor. The shared drain/source P+ diffusion region is formed in an N? well. Underlying the drain/source P+ diffusion region is a N implant having the same lateral extent of the drain/source P+ diffusion region to provide a lower programming voltage for the floating gate transistor and improved punch-through resistance for the select gate transistor.

Abstract: A high-brightness flat lamp structure comprises a reflecting plate, a plurality of UV light sources, a macromolecular polymer layer and a fluorescent powder layer. The UV light sources and the macromolecular polymer layer are sandwiched between the reflecting plate and the fluorescent powder layer. The functions of diffusing and guiding light of the macromolecular polymer layer are exploited to let UV lights emitted by the UV light sources and reflected by the reflecting plate excite the fluorescent powder layer to radiate high-brightness visible lights. Besides, macromolecular polymer and fluorescent powder can be mixed up to form a mixed layer of macromolecular polymer and fluorescent powder to let UV lights emitted by the UV light sources and reflected by the reflecting plate directly excite fluorescent powder to radiate high-brightness visible lights.

Abstract: The alternative-step appliance rotary engine is a rotary piston internal combustion engine. The alternative-step appliance rotary engine has twin or double twin pistons that rotate in a circular cross-section cylinder. The unique characteristic of this alternative-step appliance rotary piston engine is that it has a stop-piston that, when locked, cannot rotate until it is unlocked. Another rotary piston or a pair of rotary piston performs the four processes of the internal combustion engine: air absorption, compression, expansion, and exhaustion.

Abstract: The present invention discloses a hanging connector, comprising a connector body, and two grooves surrounding said connector and having a cylindrical supporting section at the center of said two grooves. Two fixed hanging points are defined between the connector and the fixed object and the hanging object, and such fixed hanging point varies according to the corresponding position or error situation of the hole position to compensate the error of distance between the holes of the fixed object and the hanging object. Even in the case of having an error in the hole position, the hanging object can still be successfully fixed onto the fixed object and maintain a relative secured position.

Abstract: The present invention discloses a foldable computer desk, comprising a rear frame and two side frames, and a rear edge of a frame and said rear frame are coupled by a movable axle, and said two side frames are folded to the front of said rear frame and unfolded to the left and right sides in front of said rear frame; a plurality of desk boards, each at both sides of its rear edge being pivotally coupled to said rear frame with two movable axles, and each desk board being lifted and leaning against the front of said rear frame and unfolded horizontally between said two side frames; and a plurality of desk board supporting members; when the desk boards being unfolded horizontally to support the open end of said desk board; by means of the foregoing structure, the computer desk being capable of folding for storage and unfolding for use.

Abstract: In a method for manufacturing a high-brightness planar lamp, a reflecting plate is first provided, and several UV light sources are placed on the reflecting plate. Next, liquid macromolecular polymer is uniformly coated on the reflecting plate and the UV light sources, and fluorescent powder is then uniformly coated on the macromolecular polymer. In another method for manufacturing a high brightness planar lamp, a reflecting plate is first provided, and several UV light sources are placed on the reflecting plate. Next, fluorescent powder and liquid macromolecular polymer are mixed up and uniformly coated on the reflecting plate and the UV light sources. A solidification procedure is then performed. The solidification ways of the mixture of fluorescent powder and macromolecular polymer includes solidification by heating and solidification by illumination of UV light.

Abstract: A combination computer desk is constructed to include two main desks arranged at right angles, and an auxiliary sector desk connected between the main desks by connectors. Each main desk has pedestals, a top frame connected between the pedestals, the top frame having two opposite sides respectively fitted into a respective horizontal mounting groove in each pedestals and fixedly secured thereto with screws, and a main table top mounted in the top frame.

Abstract: The present invention is an electropolishing/grinding means for an inner surface of a long tube, which comprises at least one long tube, one electrode, at least two partitions, one fixed magnet mechanism, one driving apparatus and an axial driven mechanism; wherein, cooperation of the partitions, the fixed magnet mechanism and the driving apparatus is to form a magnetic levitation effect, which means using magnetic repulsiveness and magnetic attraction to keep away from the partitions and inner surface and avoid the eccentric situation; further, one of the two partitions has plural springs, plural protruding objects and plural abrasives to cooperate each other for firmly the abrasives touching onto the inner surface.
