    • A porous aromatic imide polymer membrane usable as a gas or liquid separator or concentrator is prepared by a process comprising the steps of:(1) dissolving 3 to 30% by weight of an aromatic imide polymer which comprises at least 80 molar % of a recurring unit selected from those of the formulae (I) and (II): ##STR1## wherein R represents a divalent aromatic or heterocyclic radical in 70 to 97% by weight of a solvent consisting essentially of a homogeneous mixture of:(A) 100 parts by weight of a base solvent which consists essentially of at least one polar organic compound and is capable of dissolving therein said aromatic imide polymer in a concentration of 5% by weight or more therein and of evaporating at a temperature of from 50.degree. to 400.degree. C., and(B) 5 to 150 parts by weight of an additional liquid which consists essentially of at least one polar organic compound, is incapable of dissolving therein 3% by weight or more of said aromatic imide polymer and is capable of evaporating at a smaller evaporating rate than that of said base solvent at the above-mentioned evaporating temperature so as to provide a dope solution:(2) forming a thin layer of the dope solution; and(3) heating the thin layer of the dope solution at a temperature of from 50.degree. to 400.degree. C., whereby said mixed solvent is gradually evaporated from the thin layer of the dope solution.

    • The torque limiter includes a flywheel, a clutch plate, a spline hub, a clutch disc assembly and a transmission torque limiting part. The flywheel includes a friction coupling surface. The clutch plate includes plural axial through holes. Plural friction members are respectively attached to the through holes. The spline hub can be engaged with a transmission-side shaft. The clutch disc assembly circumferentially elastically couples the clutch plate and the spline hub. The transmission torque limiting part limits torque to be transmitted from the flywheel to the transmission-side shaft while the friction members are interposed and held between the transmission torque limiting part and the friction coupling surface of the flywheel.
    • 扭矩限制器包括飞轮,离合器片,花键轮毂,离合器盘组件和变速器扭矩限制部件。 飞轮包括摩擦联接表面。 离合器片包括多个轴向通孔。 多个摩擦构件分别连接到通孔。 花键轮毂可以与传动侧轴接合。 离合器盘组件周向地弹性地联接离合器片和花键轮毂。 传动扭矩限制部分限制了将摩擦部件夹持在传动扭矩限制部和飞轮的摩擦联接面之间从飞轮传递到传动侧轴的扭矩。
