    摘要： A foundation pile includes a tubular wall, a top cap covering a top end of the tubular wall, a partition plate disposed transversely in the tubular wall below the top cap and dividing an inner space of the tubular wall into upper and lower spaces, two opposite fixing holes extending radially through the tubular wall and communicated with the upper space, and a plurality of pressure release holes extending radially through the tubular wall and communicated with the lower space. The partition plate prevents concrete slurry from flowing into the upper space. The pressure release holes allow the concrete to consolidate therein and to thereby increase transverse binding forces with the foundation pile. A method of installing the foundation pile is also disclosed.

    摘要： A film capacitor comprising (1) of electric conduction electrodes and (2) of semi-crystalline polymeric dielectric film(s), the thickness of which ranges from 1 micron to 80 micron, made by a melt-stretching extrusion process through a die (circular die or flat die) with a drawdown ratio of 30 or higher (the ratio of die gap to the film thickness) at die temperatures higher than the melting point of said semi-crystalline polymer(s). The semi-crystalline polymeric dielectric films made by such melt-stretching extrusion process show a significantly low shrinkage at high temperatures until they are melted. The capacitor comprising such low shrinkage film dielectrics can be used at a much higher temperature than comprising conventional biaxially oriented film dielectrics made of the same plastic materials.

    摘要： This invention relates to a process for crystallizing and solid state polymerizing polymers, in the form of amorphous pellets by coating the pellets with a coating of 50 to 250 ppm of an anti-sticking agent to the amorphous pellets. The invention also relates to such a coated pellet. The coated pellet is then heated such that its surface is at least partially crystallized or essentially crystallized. Next it is solid state polymerize to a high molecular weight. The capacity of the crystallization and solid state polymerization process can be increased by using higher temperatures when the anti-sticking agent is present as compared to a normal process using the same polymer. The preferred anti-sticking agents are chosen to give high clarity to articles made from the high molecular weight pellet. The preferred anti-slicking agent is fumed silica, but other organic and inorganic coatings may be used.
