Abstract: A method for preparing dehydrocavidine, dehydroapocavidine and their respective composition is provided. The composition is first prepared by isolating and purifying the quaternary ammonium alkaloid components from the medicinal plant “Yan Huang Lian” (Corydalis saxicola Bunting) through the processes of solvent extraction, water-phase organic extraction, crystallization and recrystallization, and then drying to obtain said composition containing dehydrocavidine and dehydroapocavine. When necessary, the composition or their crude extracts can be separated by chromatography to obtain dehydrocavidine or dehydroapocavidine. Dehydrocavidine, dehydroapocavidine or their respective composition can be used in manufacturing medicines for treating viral hepatitis, hepatic injury, influenza, AIDS, tumors or arrhythmia.

Abstract: A pull-rotary filter switch with a fool-proof effect to avoid accidentally cut off power supply includes a rotary switch device, a transmission line and a filter. The rotary switch device has a casing, a fixing seat, a substrate, a pull-rotary button and a contact terminal. The casing has an opening and a through hole. The fixing seat has a penetrating hole, a first eccentric hole and a second eccentric hole. The substrate has a conductive point and a board hole. The contact terminal is disposed on one end of the eccentric rod and contacted to the conductive point. The transmission line is electrically connected to the transmission line, which passes through the shaft hole, the penetrating hole, the board hole, and the through hole to electrically connect to the conductive point.

Abstract: The present disclosure provides a safety bra support comprising an arc-shaped steel wire in which the special characteristic is that at least two ends of the underwire are enclosed with at least one set of thermally contractible cases made of polymeric materials. The external end of the thermally contractible case is a soft tube which protrudes outwardly beyond the end of the arc-shaped underwire, and such a soft tube is bendable and flexible, ensuring the tips of the underwire be placed at the end stitches of the sleeve. Because the above described structure is used, the present disclosure not only can effectively prevent injuries to users caused by the ends of the underwire poking through the sleeve of the bra support, but can also provide a seamless and natural fit, and the utmost comfort to wear.

Abstract: A multi-panel monitor displaying system has a multi-panel monitor supported by one integrated Liquid Crystal Display Glass Module (LGM). The multi-panel monitor contains visually un-detective gaps between panels and, therefore, can provide viewers with high quality visual effect with low productive cost. A set of LGM technologies is utilized to re-design and integrate a plurality of LGMs. After integration, image rotation is also required by the multi-monitor displaying system to ensure perfect image displays.

Abstract: The present invention provides a transmission mechanism for disk player driving systems, mainly improves the disadvantages of the currently available technology, such as complicated structure and high production cost. The present invention includes a slot for inserting recording media, the slot is flanked by a chassis, a plurality of wall troughs with downward curves at the back end are formed on each side of the chassis, a transfer base installed inside the slot with a plurality of guide bars extend and intersect the chassis, the guide bars guide the inserted recording medium onto the required position for reading.
