A secondary battery includes a battery casing accommodating an electricity-generating element group, and a battery cover having through-holes and sealing an opening in the battery casing. A first face at one end of each of positive and negative electrode connecting plates, which are each formed from a single plate of metal, is connected to a non-coated section of the electricity-generating element group. A second face at the other end of each of the positive and negative electrode connecting plates is a face onto which a busbar is welded, and the second face is exposed outward from one of the through-holes. Insulating base materials are interposed between THE positive and negative electrode connecting plates and an outer circumference of each through-hole, the insulating base materials and the battery cover are connected by brazing, and the insulating base materials and the positive and negative electrode connecting plates are connected by brazing.

A secondary battery includes a battery can 1 and a battery lid that seals an opening of the battery can 1. In a space defined by the battery can 1 and the battery lid 3, a power generation element group 6 formed by winding a positive plate and a negative plate are disposed. The battery can is formed in a shallow, bottomed rectangular shape, in which a length of one side perpendicular to a bottom of the shallow bottomed rectangle is smaller than lengths of other two sides. In the opposite ends of the power generation element group 6, uncoated sections 6A and 6B where no active material mix is coated are exposed. The power generation element group 6 is disposed so that the uncoated sections 6A and 6B are positioned directly above the through holes 1B. The connection members electrically and mechanically connected to the uncoated sections 6A and 6B are included to provide electrical continuity with an outside of the battery through the through holes 1B.

An electricity storage module includes: an electric storage unit block that is constituted by arraying a plurality of prismatic electric storage units through a holding member; and a cooling channel that is formed between the electric storage unit and the holding member, through which a cooling medium for cooling the electric storage unit flows. A part of a cooling medium inlet opening of the cooling channel is covered so that a flow speed of a cooling medium after flowing into the cooling channel is higher than a flow speed of a cooling medium before flowing into the cooling channel.

A wireless impulse transmitter that is for transmitting pulse trains to a plurality of receivers, includes a pulse selector, a pulse supplier, and a transmission unit. The pulse selector is for selecting, from a plurality of orthogonal pulse shapes assigned in a two-to-one correspondence with the receivers, pulse shapes corresponding to symbols of an input data stream. Each of the two pulse shapes assigned to each receiver represents either one or zero to the corresponding receiver. The pulse supplier is for supplying pulses in pulse shapes selected by the pulse selector. The transmission unit is for transmitting the pulses supplied from the pulse supplier in pulse trains, wherein pulses with pulse shapes assigned to different receivers are transmitted simultaneously.

This invention has as its object to implement the constitution of a receiver that receives signals sent by performing multi-valued pulse modulation and performs iterative decoding. The constitution includes: (1) a bank of pulse correlators that achieves correlation with all predetermined sent pulse waveforms, (2) a pulse demapper that calculates the log likelihood ratio for each bit of the interleaved code word from said pulse correlator outputs and a priori information for each bit, (3) a deinterleaver that performs deinterleaving on the output from said pulse demapper, (4) a decoder that calculates likelihood information for the deinterleaved code word bits and information bits, respectively, (5) an interleaver that interleaves the output of the decoder in the same manner as on the sending side, and (6) a feedback circuit that provides feedback of the output of said interleaver as a priori probability to the pulse demapper.
