    摘要: Disclosed is a method for preparing polyester resins copolymerized with glycol for modification such as 1,4-cyclohexanedimethanol, in which the content of said glycol ingredient for modification ranges from 20 to 80 mol % of the total glycol content. Dicarboxylic acid such as terephthalic acid is esterified with ethylene glycol and said glycol for modification. The esterification product is subjected to polycondensation in the presence of a titanium dioxide/silicon dioxide coprecipitate catalyst, said catalyst being in the form of 4% or less strength by weight suspension in glycol. The copolyester prepared as above shows excellent transparency and color properties in addition to being produced at high efficiency.

    摘要: A heat fixing roller in an electrophotographic recording system provides a high degree of radiating efficiency and reduces the amount of time it takes for the heat fixing roller to achieve a temperature necessary to perform a printing operation. The heat fixing roller has a heat lamp installed along a center axis within an interior portion of the heat fixing roller. A plurality of hollowed-out heat conduits extend outwardly in a radial manner from the heat lamp to provide a path through which heat generated by the heat lamp can radiate to rapidly increase the temperature of an outer surface of the heat fixing roller.
