Title: Manufacture of lead alloy rolled sheet for lead-acid battery grid
Inventor: OMAE TAKAO
IPC: H01M4/74
Filed: 1999-07-13
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method for a rolled sheet which reduces a rupture of a bridge during manufacturing an expand grid, and has an excellent mechanical strength. SOLUTION: In a manufacturing method for a lead alloy rolled sheet, a quenching process in vapor phase is conducted after a rolling process, and the quenched state is maintained for a constant time. Preferably, the quenching process is conducted at a speed of 5 deg.C/min or more, and the temperature of the lead alloy rolled sheet is maintained at 10 deg.C or less for 1 hour or more. Quenching after rolling increases the mechanical strength of the lead alloy rolled sheet after hardened. The quenching without using water prevents the sheet surface from being oxidized. Maintaining the cooled state after quenching increases stability in machining.

IPC: G01F1/28
Filed: 1988-08-10
Abstract: PURPOSE:To simplify a circuit construction of a system by detecting a flow in a circulation system from the displacement of a float positioned in the water of the circulation system. CONSTITUTION:A flowing water detecting device 10 having a float 9 which is positioned in the water flowing in circulation to a circulation system 3 and is displaced from a free state with the movement of the circulating water and which has a specific gravity a little larger than the specific gravity of the water, is fitted to a warm water storing tank 2, in a state that it is suspended by its weight from the upper part of the tank. When the water circulates to the circulation system 3, the float 9 is pushed up to be displaced along a guide rod 12 by a jetting flow of the water from a return port, and a driving magnet 13 drives a reed switch 11. When there occurs a trouble in the circulation system 3 and the circulation of the water is interrupted, on the other hand, the float 9 sinks along the guide rod 12 and turns off the reed switch 11. Since the flowing water detecting device 10 is accommodated in the tank in this way, a circuit construction of the circulation system can be simplified.
