A wire winding box of a replaceable connecting receptacle includes a wire winding box and a replaceable connecting receptacle. The shape of the rotor is such that the gap permeance, which is based on the gap, varies according to a sine function of the rotational angle. Springs are compressed between the top and bottom plates. 2 to 1 ppm in terms of weight based on the weight of component B; and 0. In another implementation, the population of fine fibers has a population median diameter less than 1 \u03bcm. A pinch threshold is then adjusted based on the pinch factor to define a modified pinch threshold.
