A mail wrapping system apparatus for preparing for mailing postal items includes receiving trays for respectively receiving postal items from companies and an extraction device for extracting from the postal items a multiplicity of same address groups of the postal items, each of the same address groups consisting of ones of the postal items having coinciding ones of destination addresses. A wrapping unit respectively individually assembles each of the same address groups into a bundle and successively wraps each of the same address groups assembled using a wrapping component with a corresponding one of the destination addresses respectively displayed on each of the wrapped same address groups to provide for mailing the wrapped same address groups. A weight sorter then sorts the wrapped same address groups into weight divisions set forth by a fee schedule of a specified delivery agency and the wrapped same address groups are sent with appropriate postage.

A sealed lead-acid battery includes a separator made from hydrophilic treated sheet made from synthetic fiber which wraps at least either one of a positive electrode and a negative electrode. A mat type separator made from fine glass fiber is disposed between the wrapped electrode and its opposite electrode. This structure is adopted in a battery which uses a paste type electrode where an expanded grid having no outer frame on both edges is used, thereby prolonging cycle life even after cycling of charge and deep discharge.

Disclosed is a non-aqueous electrolyte secondary battery having an electrode group in which a positive electrode and a negative electrode are spirally wound with a separator interposed therebetween. The positive electrode contains a positive electrode active material and a binder. The positive electrode active material contains a mixture of two different particulate substances having different average particle sizes. The two different particulate substances are lithium composite metal oxides containing nickel as an essential element. The binder includes fluorocarbon resin and rubber particles. The fluorocarbon resin contains at least a vinylidene fluoride unit. The amount of the rubber particles per 100 parts by weight of the fluorocarbon resin is 1 to 25 parts by weight.

A group of electrodes are accommodated in a prismatic cell case of a rechargeable battery. Intervening separators are provided between positive and negative electrode plates arranged alternately in parallel to long lateral walls of the cell case. The positive electrode plates each include a lead portion having a surface on which at least one lead plate is attached. Lateral edges of the positive electrode plates protrude beyond the negative electrode plates on one side, and lateral edges of the negative electrode plates protrude beyond the group of positive electrode plates on the opposite side. The protruding portions form the lead portions. Upper open ends of the cell cases are closed by an integral lid member.

An SOF measuring system that can continuously measure SOF and a soot measuring system that can continuously measure soot are connected with an exhaust gas line. The soot measuring system comprises a diluter that selectively dilutes either one of the exhaust gas and standard gas whose hydrocarbon concentration is known with diluent gas and extrudes it. A dilution ratio adjusting device can adjust a dilution ratio of the diluter. A soot detector continuously detects soot in the exhaust gas or the standard gas diluted by the diluter. The SOF measuring system can be connected with the diluter so that an exhaust gas analyzer can measure the hydrocarbon concentration in the standard gas diluted by the diluter.
