    摘要： The present invention relates to a polyolefin that has high environmental stress cracking resistance (ESCR), a high impact property, and an excellent die swell property, and a method of preparing the same. According to the method of preparing polyolefin of the present invention, a supported hybrid metallocene catalyst and an alpha olefin comonomer having 4 or more carbon atoms are used to obtain polyolefin having the bimodal or multimodal molecular weight distribution curves during the single reactor polymerization. The polyolefin has excellent processability, a melt flow rate ratio (MFRR) that is useful to processing, excellent shapability, impact strength, tensile strength, in particular, environmental stress cracking resistance (ESCR) and full notch creep test (FNCT), thus being used to manufacture the blow molded product.

    摘要： A multi-focusing laser beam recorder and a multi-focusing method includes first and second light sources for generating a Kr laser beam for recording light and an He--Ne laser beam for focusing. A fixed optical system modulates the Kr laser beam for recording light and divides the beam into a main beam and a sub beam on each of different paths. An optical divider divides the main beam or the sub beam incident through a shutter of the fixed optical system and the He--Ne laser beam incident from the second light source. A focus servo focuses either the main beam or the sub beam from the optical divider and the He--Ne laser beam on a predetermined area of the glass substrate. First, second and third position sensor controllers control the focus servo to focus the He--Ne laser beam on the glass substrate in response to the pit width of the glass substrate by sensing the laser beam for focusing reflected upon the glass substrate. In such a multi-focusing laser beam recorder, it is possible to reduce required time and price related to process steps and to enable using the position sensors to cut any pit.
