1. Functional seating furniture, in particular for office use, comprising a frame (1), a seat (2) pivotable about a horizontal frame axis against the force of at least one spring and of adjustable inclination, and also a backrest (3) pivotable in dependence on the respective inclination of the seat, characterized in that the front part of the seat (2) is supported, in particular in the side region...

PURPOSE:To enable a battery to be formed concurrently small and thin, by forming a small hole and a projecting part in a part of film or sheet which covers a group of electrode plates and bending the projecting part to cover the small hole and partially performing thermal welding on its bent part and then injecting silicon oil into the gap, so that a safety valve can be formed. CONSTITUTION:A smal...

PURPOSE:To increase an active material per unit volume and improve conductivity, by enveloping an electrode plate, shaped in a lattice of no frame and filled with an active material, by using a bag-shaped retainer. CONSTITUTION:A positive and negative grid 5 is shaped in a lattice of no frame, with the whole surface area or the most part excluding the lugs in the grid being filled with an active m...

PURPOSE:To prolong a life of cathode plates, by performing the first energizing on a group of electrode plates, then stopping the electrification to add sulfuric acid into a battery jar and leave the group for definite hours as it is, and thereafter performing the second energizing on the group in the battery jar into which sulfuric acid has been added. CONSTITUTION:A group of electrode plates in ...

PURPOSE:To improve charging recoverability, by equipping a negative plate in which sulfuric acid is retained and a material having electric conductibility is contained. CONSTITUTION:A lead storage battery, in which electrolytic solution is not fluidized or is contained into a holding matter (a retainer), is equpped with a negative plate in which sulfuric acid is retained as electrolytic solution a...

PURPOSE:To prevent the unwinding of a roving end, by rotating a roving bobbin along the roving-winding direction with a bobbin rotating apparatus while holding the bobbin with a posture-maintaining apparatus and a pressing apparatus. CONSTITUTION:The posture of a roving bobbin 1 is maintained by a posture- maintaining apparatus 44 in the course of passing the bobbin 1 on a bobbin carriage 11. The ...
