Title: Manufacture of sealed lead-acid battery
Inventor: TOKUNAGA AKIO
IPC: H01M4/68
Filed: 1989-11-06
Abstract: PURPOSE:To make a lead-acid battery lightweight and obtain high performance by immersing an expand-machined copper lattice in a molten metal with the melting point higher than that of lead to form the first film layer, and immersing it into molten lead or lead alloy to form the second film layer. CONSTITUTION:An expand-machined copper lattice is immersed in molten metal with the melting point higher than that of lead, e.g. zinc or aluminum, to form the first film layer 4, then it is immersed in the molten lead or lead alloy to form the second film layer 5. When the copper lattice is immersed in the molten metal with the melting point higher than that of lead, a lattice frame 1 is formed into a roundish cross section shape with no edge section as a whole, thus uniform film layers 4 and 5 are formed by immersing it in molten lead. The elution of copper is prevented by simple fusion plating, a lead-acid battery is made lightweight, and its performance is improved.

Abstract: PROBLEM TO BE SOLVED: To prevent the retention of bubbles, and properly keep the tension of a belt in a hydraulic auto tensioner where the tension of a timing belt or the like is properly kept, by comprising a means for communicating an internal space in the radial direction of a coil at the other end of a coil spring, to a small gap. SOLUTION: A rod 13 of a hydraulic auto tensioner 10 is elastically brought into contact with an oscillating idler by the fluctuation of the tension of a timing belt, and the oscillating idler is oscilated on an oscillation fulcrum. In the hydraulic auto tensioner 10, a check ball 21 closes the communicating path 12d, when the tension of the timing belt is increased, so that the hydraulic fluid in a pressure chamber 15 is gradually leaked to a reserver chamber 16 through a small gap 25. On this occasion, the internal spaces in the radial direction, of a coil at both edges of a coil spring 24 are communicated to each other by four grooves 30 formed on an edge face of a stepped part between a large diameter cylindrical part 12b and a small diameter cylindrical part 12a of a plunger 12. Thereby the remaining of the bubbles in the pressure chamber 15, can be prevented.
