The invention relates to a axial pre-compress method of integrated ball hinged rubber flexible element and relative product, which comprises a metallic sheath, a flexible rubber element, a metallic inner sheath and a core axle. It is characterize in that: metallic sheath, flexible rubber element and the metallic inner sheath are independent two-section integrated structures, which are connected along the axle on the core axle; the flexible rubber pre-compress stress is realized by adjusting the axial position between the metallic sheath and the metallic inner sheath. And said stress can be formed by the axial separated two sections axially compress the metallic inner sheath and adjust the axial position of metallic inner sheath on the core pin.

The invention is concerned with an antenna arrangement adapted to a mobile terminal and division of frequency bands between different antennas. The antenna arrangement enables the terminal to operate worldwide in networks applying different frequency bands and technologies, as a so-called multi-band terminal. In the antenna arrangement the frequency bands of the antennas are arranged for each antenna in a way that the bands fill an optimal frequency area, thus accomplishing smaller total volume for the antennas and a good performance.

The invention provides a writing instrument, which avoids drop when ball pen nips on cloth. Concretely, head (2) of the ball pen is located in the front part (3a) of axis (3), penpoint (9) extends from the head (2), and length of nip (4) on back of the axis (3) is approximately same to the length from back end (3b) of the axis (3) to the front part (3a) of the axis (3).

The invention relates to the exsolution, centrifugation and drying integrated technology in the industrial production of poly propylene carbonate, which belongs to the technical field of the synthesis of the industrial production of the poly propylene carbonate and the post treatment of the product. The technology comprises: injecting the poly propylene carbonate slurry continuously into a sealedelevated tank by a slurry pump; entering a centrifuge after leaving the elevated tank; putting the slurry continuously into the centrifuge to be centrifugalized to ensure that the moisture content (weight) of the wet material is less than 50 percent; putting the wet material coming out of the centrifuge into a horizontal drier to be dried for 1-6 hours and putting mother liquor into a mother liquor tank; putting the solids with less than 1 percent of moisture content (weight) coming out of the horizontal drier continually into a vertical drier to be dried for 1-4 hours to ensure the moisture content (weight) is less than 0.2 percent after drying; obtaining the ultimate solid which is the finished product of the poly propylene carbonate; and condensing and recovering the fugitive constituents to be led into the mother liquor tank. The technology of the invention has the advantages of complete sealed entire process, complete liquid constituent recovery, continuous technological process,smooth and integrated design, simple equipment and low production and labor cost, which is particularly suitable for industrial production.
