    摘要: A direct current relay includes a plurality of contact pairs, and a plurality of magnets (5). Each of the plurality of contact pairs is configured having contacts (21, 22, 31) with contact regions (21a, 22a, 31a) disposed to allow opening and closure with respect to each other. The plurality of contact pairs are disposed such that the plurality of magnets (5) are disposed on one straight line, and the contact pairs are located between the magnets (5) on a line identical to the straight line. Each of the plurality of magnets (5) is provided to distort an arc generated between contacts (21, 22, 23, 31) on an occasion of relay cut off in a direction crossing the straight line. Even if a backward current flows, arcs will not interfere with each other, allowing extinguishing in a short time. Accordingly, a direct current relay can be obtained, capable of cutting off a high direct current voltage in a short time even on an occasion of backward current while minimizing the number of magnets and allowing down-sizing with a simple structure.

    摘要: A melt-processable fluorine-containing polymer is melt kneaded with a kneader which has a residence time of at least 10 minutes, a usable volume ratio (usable space in a container/space in a container) of larger than 0.3, and a power factor K of less than 8000, the power factor K being represented by the formula: K=Pv/&mgr;/n2 in which Pv is a power requirement per unit volume (W/m3), &mgr; is a melt viscosity (Pa.s), and n is a rotation speed (rps), to effectively remove terminal groups and bonds in the backbones, which are unstable during melt kneading, from the melt-processable fluorine-containing polymer, and obtain a colorless fluorine-containing polymer.

    摘要: Coagulated particles having a low water content are separated and recovered from an emulsified dispersion of fluorine-containing polymer particles. A solid-liquid separation method comprising: a step for adding a coagulant in an emulsified dispersion of fluorine-containing polymer particles to coagulate the fluorine-containing polymer particles with stirring and obtain a slurry of coagulated particles, a step for filtrating the slurry, and a step for pressing the obtained cake. It is preferable to continuously carry out the filtration step and pressing step with a filter press or a belt press. Also a washing step may be provided after the filtration step.
