    • Tubing (31) made from a mixture comprising polyimide and fluororesin particles through molding and heat curing wherein at least part of the fluororesin particles present in the neighborhood of the surface layers of the tubing (31) precipitate on the outside or inside surface of the tubing (31) through melting and flowing and form a fluororesin film over part or the whole of the surface. The tubing (31) can be produced by applying a mixed dope obtained by adding fluororesin particles to a polyimide precursor dope on the outside surface of a mold, cast-molding the coating in a predetermined thickness, heating the resulting coating to attain imidation with the maximum temperature of the imidation exceeding the melting point of the fluororesin, cooling the coating, and separating the resulting tubing from the mold. Thus, the invention provides tubing which is lowered in the coefficient of kinetic friction particularly of the outside surface and is advantageous in durability and manufacturing cost; and a process for the production thereof.
    • 通过模制和热固化由包含聚酰亚胺和氟树脂颗粒的混合物制成的管(31),其中存在于管(31)表面层附近的至少部分氟树脂颗粒在管的外表面或内表面上沉淀 (31)通过熔化和流动,并在部分或整个表面上形成氟树脂膜。 管道(31)可以通过将通过将氟树脂颗粒添加到模具的外表面上的聚酰亚胺前体涂料中而获得的混合涂料来制备,将预定厚度的涂布模塑,加热所得到的涂层以获得酰亚胺化 酰亚胺的最高温度超过氟树脂的熔点,冷却涂层,并将所得管道与模具分离。 因此,本发明提供了特别是外表面的动摩擦系数降低的管道,并且在耐久性和制造成本方面是有利的; 及其生产方法。

    • A fusing unit and a fusing apparatus using the same are provided to block current during overheating by using a blocking unit such as a bimetal having a rapid response to heat, thereby preventing a fire or the like caused by overheating. A fusing unit comprises the followings: a tubular fusing roller which has a heat generating unit and has electrode units in its both ends; a power supply unit(170) which is in contact with the electrode unit and supplies current; and a blocking unit(160) which is installed between the electrode unit and the power supply unit, and blocks current supply by separating the power supply unit from the electrode unit when a temperature of the heat generating unit rapidly increases. The power supply unit has a brush(171) contacting with the electrode unit, and has an elastic unit(173) for giving an elastic force to the brush so as to contact with the electrode unit.
    • 提供了一种定影单元和使用其的定影装置,以通过使用诸如双金属片的阻挡单元在过热期间阻挡电流,从而防止由于过热而引起的火灾等。 定影单元包括:管状定影辊,其具有发热单元并且在其两端具有电极单元; 电源单元(170),其与所述电极单元接触并提供电流; 以及安装在电极单元和电源单元之间的阻挡单元(160),并且当发热体单元的温度快速上升时,通过将电源单元与电极单元分开来阻止电流供应。 电源单元具有与电极单元接触的刷子(171),并且具有用于向电刷产生弹性力以与电极单元接触的弹性单元(173)。
