Abstract: Disclosed are a continuous rolling device and method with interfacial temperature-force controllability for a seamless metal cladding pipe. The device comprises a multi-roller skew rolling mill set, an interfacial temperature-force controlled rolling mill set and a sizing and finishing mill set sequentially distributed along a rolling axis; and the interfacial temperature-force controlled rolling mill set comprises an interface temperature control module and an interface pressure control module sequentially distributed along the rolling axis, the interface pressure control module comprises two racks and a plurality of controlled rolling rollers circumferentially and evenly distributed along the rolling axis, two ends of the controlled rolling roller are respectively mounted on the two racks through corresponding screwdown apparatuses, and the interface pressure control module realizes passive driving through a spiral pushing force or a traction force.

Abstract: A small integrated free space circulator, comprising a first polarizing beam splitter (1), a half-wave plate (2), a Faraday rotating plate (3), a beam splitter (4), a quarter-wave plate (5), and a pair of reflective plates (6, 7), wherein the first polarizing beam splitter (1), the half-wave plate (2), the Faraday rotating plate (3), and the beam splitter (4) are sequentially arranged, the quarter-wave plate (5) and the reflective plate (6) are sequentially attached to a side surface of the first polarizing beam splitter (1) adjacent to the half-wave plate (2), and the reflective plate (7) is arranged on a side surface of the beam splitter (4, 8) adjacent to or opposite to the Faraday rotating plate (3); when the reflective plate (7) is arranged on the side surface of the beam splitter (8) opposite to the Faraday rotating plate (3), the reflective plate (7) partially covers the side surface of the beam splitter (8) opposite to the Faraday rotating plate (3).

Abstract: A vertical cavity surface emitting laser (VCSEL)-based free space active optical transceiver component includes; a transmitter and a receiver. The transmitter includes first VCSELs, at least one first photodiode, a first focusing lens array or optical system (14), and a first printed circuit board. The receiver includes second photodiodes, at least one second VCSEL, a second focusing lens array or optical system, and a second printed circuit board. The transmission and reception of a short/medium-distance free space (wireless) high-speed optical communication signal can be implemented, and a single-channel transceiving rate may reach 10 Gbps or higher. The component may be used for implementing a free space high-speed signal transmission function in a short/medium-range high-definition multimedia interface (HDMI) device.

Abstract: A women's urinal device that allows women to urinate while standing upright to conserve water and space required by conventional toilets or commodes. The women's urinal device is adapted to be held against a woman's vaginal area to receive urine excreted from a woman, the urine then is adapted to be excreted therethrough the interior of the generally conical-shaped funnel and therethrough an aperture formed on the bottom of the generally conical-shaped funnel, where the urine is adapted to be directed into a urinal. The women's urinal device is adapted to be dispensed from a funnel dispenser that is attached to the bathroom partition adjacent to the urinal to conveniently access the women's urinal device.
