The invention relates to a three-dimensional shock isolation device. The device comprises an upper cover plate, a horizontal shock isolation part, a vertical shock isolation part and a lateral steel plate, wherein the vertical shock isolation part comprises a transition connecting steel plate, and a core connecting part which is arranged below the transition connecting steel plate; the core connecting part is laterally obliquely provided with a plurality of channel steel damping devices by hinging; the other end of each channel steel damping device is hinged to the lateral steel plate; the plurality of channel steel damping devices under a static load state can support the core connecting part as well as keeping the core connecting part balanced; an adhering elastic laminating part is arranged below the core connecting part; a lead core column body passes through a hole in the adhering elastic laminating part; a hole is formed between the adhering elastic laminating part and the core connecting part; the lead core column body with steel threads is inserted into the hole to extrude the lateral plate to be integrated with the adhering elastic laminating part and the core connecting part; the channel steel damping devices under a dynamic load state are yielded and out of stability, and the rigidity is reduced to be zero, and the adhering elastic laminating part and the lead core column body can perform the longitudinal shock isolation.

A water supply system is obtained by improving box-type non-negative pressure water supply equipment and composed of a first water inlet pipe, a gas inlet valve, a container, a first water pump and a water pipe.A gas pressure water tank or a normal pressure water tank is adopted as the container; the first water pump comprises a second water pump.The water supply system has the advantage of being continuous in flow and pressure and solves the problem of water using cycle of stored water of a water tank in the box-type non-negative pressure water supply equipment.

The invention relates to a keyless Microsoft program control hardware system, which is different from the program control and input system on the previous computer keyboard; the keyboard part of the system is the printed work which is made of independent paper medium or other materials and is completely detached from the computer body; and the keyboard part is not needed to be connected with a power supply and the computer, recognizes the information codes printed on the special material by a pen-type optical reader-writer, is connected with the computer by a USB interface, thus completing the program control to the internal software of the computer. The system can operate various system software and control programs in the computer exactly and quickly, achieves the objects of freely controlling and operating the following programs of the computer: recording, program conversion, Internet query, E-mail delivery and the like, leads the efficiency to exceed the usage of the computer keyboard, is convenient and exact, environment-protective and sanitary, has simple operation, greatly improves the usage efficiency, is beneficial to the groups who are not familiar to the computer, and provides more convenient and simpler operation environments for the olds, the disables and the blinds.

The invention discloses a method for preparing arctiin, which comprises the following steps of: crushing burdock and extracting the crushed burdock by using water or alcoholic solution; allowing the extract to directly enter an absorption column to perform adsorption and enrichment, eluting the product with the water and the alcoholic solution in turn, and performing concentration under reduced pressure to obtain arctiin fraction; and performing countercurrent chromatographic separation on the arctiin fraction by using a two-phase system formed by aqueous solution consisting of a single organic solvent and salt to obtain salt arctiin fraction, and performing adsorption to remove the salt by using macroporous adsorption resin or ion exchange resin. The method has the advantages of simple process, continuous operation, contribution to automation and recovery and recycling of the solvent, and suitability for industrial mass production.
