PURPOSE:To suppress the breakdown of active material particles, increase life of a lead-acid battery, and increase utilization of an active material by bringing a plate before formation into contact with a metal complex forming solution, then charging it in a dilute sulfuric acid solution. CONSTITUTION:A plate before formation is brought into contact with a metal complex forming solution, then cha...

PURPOSE:To increase capacity and remove gas adsorbed on the porous surface of an active material layer by immersing a plate which finished formation in a forming solution under a reduced pressure for a specified time. CONSTITUTION:A plate which finished formation is immersed in a forming solution under a reduced pressure for a specified time. For example, after performing continuous formation for ...

PURPOSE:To prevent adsorption of generated gas on the porous surface of an active material layer which formation is not yet performed by performing formation of a battery under a reduced pressure. CONSTITUTION:A plate group of a battery assembled with plates before formation is accommodated in a container and a cover is fitted, then electrolyte is poured in it. With a hole is opened, formation of ...

PURPOSE:To suppress breakdown of active material particles, increase life of a lead-acid battery, and increase utilization of an active material by forming a lead metal complex on a plate. CONSTITUTION:A lead metal complex is formed on a plate. In order to form a lead metal complex on a plate, a complex forming solution is added to a solution containing lead ion and preferably it is kept in neutra...

PURPOSE:To improve sudden discharge performance at low temperatures by using the dilute sulfuric acid in which lignin is contained in an electrolyte. CONSTITUTION:A battery consisting of four positive electrode plates and five negative electrode plates is obtained by manufacturing a substrate by the gravity casting method using a sealed type lead acid storage battery in which the glass fine fiber ...

PURPOSE:To improve life performance by thermally shrinking a resin coat cylindrical body with acid resistance in which an assembled element is housed and pressing the assembled element. CONSTITUTION:An assembled element 6 is formed by welding a plate body with a separation body 3 consisting of a positive electrode plate 1, negative electrode 2, and fine glass fiber mat using a positive electrode s...

PURPOSE:To decrease the amount of an active material separated from the pasted positive plate so as to improve the life performance of a storage battery by causing the positive plate to have surface layers each consisting of a thin film containing polytetrafluoroethylene on its both surfaces. CONSTITUTION:After the conventional active material paste cantaining a little larger amount of water is ap...

In a method of producing a lead-acid battery plate, a lead oxide-containing paste is supplied to a carrier and the exposed surface of the paste on the carrier is contacted with a layer of fibrous material. Vibrational energy is then supplied to the fibrous layer so as to cause the paste to impregnate the fibrous layer and thereby secure the fibrous layer to the plate.

A running guide system for an automotive vehicle planned for running in a sightseeing area or the like. Special running data including right or left turn, passage through a tunnel, running in a predetermined direction and passage on a slope are stored in a cassette tape together with distance data representing the distance from a start point in the form of a plurality of check point data. By colla...

A large umbrella arrangement includes a stand (2) having a mast (10) to which an extendable and retractable support arm (4) is connected. A connecting member (12) is pivotally connected to the middle area of the support arm (4) and at its other end is pivotally connected to the upper end of the mast (10). One end (26) of the support arm (4) engages the mast (10) by means of a roll (32). This end (...
