Abstract: [Problem] To provide a separator for a lead acid battery capable of suppressing electrolyte stratification and improving the battery reliability (prolongation of life during idling stop operation and stability of capacity detection) of a lead acid battery. [Solution] A separator for a lead acid battery, characterized in that the separator comprises a porous backweb and a plurality of ribs extending from each of both surfaces of the backweb, the rib on a surface on a side that comes into contact with a positive electrode plate is a broken rib, has a shape with two or more bending points, and is a linear broken rib that bends in opposite directions at each of two consecutive bending points or is a curved broken rib having one or more inflection points.

Abstract: An audio decoding device includes a playback speed change device for changing, with respect to a decoded audio signal obtained by a decoding device, the playback speed thereof; an output buffer for temporarily storing a digital audio signal outputted from the playback speed change device; a read out device for reading out the digital audio signals stored in the output buffer at predetermined time intervals; a playback speed control device for controlling the playback speed change device on the basis of the number of packets stored in the jitter buffer; and decoding timing control means for controlling the timing of decoding by the decoding device on the basis of the amount of data stored in the output buffer.
