    摘要： The present invention provides a catalyst composition for the ethylene oligomerization, which comprises 2-imino-1,10-phenanthroline coordinated iron (II), cobalt (II) or nickel (II) chloride as main catalyst and triethylaluminum as cocatalyst. The present invention also provides a process for oligomerization of ethylene is provided, wherein a catalyst composition comprising 2-imino-1,10-phenanthroline coordinated iron (II), cobalt (II) or nickel (II) chloride as main catalyst and triethylaluminum as cocatalyst is used, and the molar ratio of aluminum in the cocatalyst to central metal in the main catalyst ranges from 30 to less than 200. According to the present invention, another process for oligomerization of ethylene is also provided, wherein a catalyst composition comprising 2-imino-1,10-phenanthroline coordinated iron (II), cobalt (II) or nickel (II) chloride as main catalyst and triethylaluminum as cocatalyst is used, and the temperature of ethylene oligomerization ranges from −10 to 19° C. According to the present invention, the price of cocatalyst i.e. triethylaluminum, is low, just a fraction of that of methylaluminoxane, the amount of cocatalyst is therefore significantly reduced, with the catalytic activity is still acceptable, thus the cost of ethylene oligomerization is significantly reduced. In view of both the catalytic activity and the cost, the present invention is highly applicable in industry.

    摘要： An electric all-dimensional numerical control injection molding machine is applicable to production of injection products with high precision and complex three-dimensional shapes. The machine comprises a machine base, a main board, four sets of electric mould guiding devices, a cross-shaped chute mould assembly, and an injection device assembly. The electric mould guiding devices are mounted on a front face of the machine. A slider mould is disposed in a chute of a cross-shaped mould base, is connected to a shaft of an electric driver, and implements mould opening and closing functions by means of linear movement of the shaft of the electric driver. An injection system of the machine is used for injecting plasticized, fused, and homogenized plastic materials into a mould cavity of the mould.

    摘要： An embodiment of a method includes generating a regulated output signal from a regulated intermediate signal in response to a reference signal and the regulated output signal, and generating the regulated intermediate signal from an input signal in response to the regulated output signal and the regulated intermediate signal. By generating one regulated signal (e.g., a regulated output voltage) from another regulated signal (e.g., a regulated intermediate voltage), the magnitude of the ripple component of the one regulated signal may be reduced. Furthermore, by generating the regulated intermediate signal in response to the regulated output signal, the efficiency of the regulation may be increased.
