    摘要: A polyester film having a coefficient of dynamic friction between the film and a metal at 80.degree. C. of not more than 0.45, a polyester film composed of a polyester comprising an ethylene terephthalate unit in a proportion of 70% or more by mole, the polyester film comprising a cyclic ethylene terephthalate trimer in a proportion of 0.7% or less by weight, laminated metal sheets and metal containers manufactured from said laminated metal sheet. According to the present invention, the polyester film shows superior sliding property and superior scratch resistance during can production, as well as the elution of oligomer from the film can be suppressed, so that when the film is used for metal containers for food, the change in taste and smell of the food contained therein and degraded appearance of the surface of the film caused by the deposition of oligomer are avoided.

    摘要: Main circuit of an electric power generating apparatus for dispersed power supply, having a permanent magnet type electric power generator driven by windmill or waterwheel and having three windings, each inducing a different value of induced voltage, AC outputs of the generator rectified by rectifiers, and DC outputs of the rectifiers summed in parallel for output. First and second reactors are respectively connected in series between first and second rectifiers and output terminals of first and second windings, the first winding inducing the lowest induced voltage among the three windings, the second winding inducing the second lowest. A capacitor is connected between a third rectifier and an output terminal of a third winding inducing the highest induced voltage. The sum of inductive impedance by internal inductance of the third winding and capacitive impedance by the capacitor is capacitive impedance within a range of rotational speed of the generator.
