IPC: H01M12/08
Filed: 1991-03-29
Abstract: PURPOSE:To perform adequate control of a battery by correcting a calculation value of a charge condition with a measured value of time during flowing of a shunt current. CONSTITUTION:Time, for which a battery is actuated, is added to time, for which the battery is used before actuated, to obtain time t1 for which a shunt current flows. Next, density of an electrolyte is measured, and concentration of a zinc ion in the electrolyte is obtained from the density to calculate a charge condition(SOC). This SOC is corrected based on the time t1 and displayed. In the next reset discriminating process, the battery is detected for whether its complete discharge is provided or not. When the complete discharge is not performed, the above-mentioned process is repeated, and when the complete discharge is performed, the time t1=0 is obtained to serve as a condition of start. In this way, a proper value of the SOC can be calculated.

Title: Slow falling and rising device for rubber dam
Inventor: INOUE NOBUO
IPC: E02B7/20
Filed: 1981-05-06
Abstract: PURPOSE:To slowly gring down a rubber dam by using a device in which an exhaust pipe is connected through a valve to a rubber dam, and plural small holes are provided in the side walls at the tip portion of the exhaust pipe in such a way that the tip of the exhaut pipe is positioned below the level of water in the rubber dam when completely rising it. CONSTITUTION:Since, when a rubber dam 12 is completely risen, the tip of an exhaust pipe is located under water, when the exhaust valve 14 is opened when bringing down the rubber dam, air in the rubber dam is mainly discharged from small holes 16 positioned on the surface of water in the early period and partly from the small holes 16 positoned under water receiving resistance arising from the potential energy of dammed water. Since the opening area of the small holes 16 from which air is discharged to the open air is sufficiently small, the falling speed of the rubber dam 12 by the discharge of air is very slow. Thus, the amount of overflow in the early period of falling can be controlled to a minimum.
