Abstract: A floating mechanism (300) and an ultrasonic diagnostic apparatus. The floating mechanism (300) and the ultrasonic diagnostic apparatus can implement the direct superposition of lifting movements and rotational movements, so that the floating mechanism (300) can move in more directions. In addition, a lifting structure and a rotation structure in the floating mechanism (300) are integrally linked in design, accordingly, the link performance is good, the response is fast, the occupied space is small, and the operation range is great.

Abstract: A floating mechanism comprises a lift arm, a translation arm and a connection frame. One end of the lift arm is rotatably connected to the connection frame which is also rotatably connected to the translation arm. The lift arm drives the translation arm to rotate and move up and down between two intersecting planes with a fulcrum at the other end of the lift arm opposite to the translation arm. The translation arm can also be translated in a translational plane intersecting the lift arm with the connection point of the translation arm and the connecting frame as an axis. The lift arm and the translation arm of the floating mechanism can together drive an operating panel to move up and down in a vertical plane and to translate front and back, and left and right in a translation plane; meanwhile, the operating panel can be driven to rotate in the translation plane along with the lift arm and the translation arm.

Abstract: A lock device is disclosed, which includes: a holder which is provided with a through hole running through the holder and a slide intersecting with the through hole; a guide bar, which is provided with an outer threaded area on at least a portion of a surface and passes through the through hole, and the outer threaded area is located where the through hole intersects with the slide; a lock component received in the slide, and the end of the lock component facing toward the guide bar is provided with a lock threaded area which can engage with the outer threaded area of the guide bar; and a drive assembly which drives a lock assembly to move toward or away from the guide bar in the slide. The guide bar is locked when threads on the lock threaded area engage with outer threads on the outer threaded area.

Abstract: Compounds useful for making HCV protease inhibitors are described. Methods of using these compounds to make HCV protease inhibitors are also provided.

Abstract: The invention provides fiber-optic detectors with rapid response times for measuring analytes in aqueous solutions, including blood. The detectors, because of their size, accuracy, and sterilizability may be used in vitro. In a preferred embodiment, pellets comprising a unique, permeable terpolymer of methyl methacrylate, butyl acrylate and methacrylamidopropyltrimethylammonium chloride; and an indicator for an analyte are used as the detecting element of a fiber-optic sensor. Response times for pH testing are better than 150 seconds at t90%. The pellets are easily made by solvent casting techniques and failure rates are low.
