IPC: H01M4/62
Filed: 1995-12-12
Abstract: PROBLEM TO BE SOLVED: To restrain the degradation of electrode performance caused by improper paste viscosity, restrain reduction in battery capacity caused by decomposition of a thickener at overcharge time, and restrain an excessive increase in battery internal pressure at charging. SOLUTION: Theoretical capacity of a negative electrode is formed so as to become equal to the total of prescribed charging reserve and discharging reserve to theoretical capacity of a positive electrode, and the charging reserve is set not less than a discharging reserve increasing quantity caused by decomposition of a thickener in both electrodes by oxygen gas at over charging. Here, the discharging reserve increasing quantity is regulated by (an electron generating quantity Ah x the total quantity mol of the thickener).  By being constituted in this way, oxygen generated in a positive electrode at overcharging reacts with the thickener, and decomposes the thickener, and even if the discharging reserve increases, theoretical capacity of the negative electrode does not become less than the total of theoretical capacity of a positive electrode and the discharging reserve, and an increase in battery internal pressure by a too small quantity of the charging reserve can be prevented.

Abstract: PURPOSE:To improve correction accuracy of driving current by providing a current generating unit for generating at least two levels of current and a light quantity measuring unit, and measuring each quantity of light emission by driving a plurality of LEDs alternately with at least two levels of current. CONSTITUTION:Quantity P0, P1 of light produced from an LED for driving current I0, I1 are measured and the characteristic in a section, where the driving current takes a value between 0 and I0, is approximated by a dot line 2 while the characteristic in a section, where the driving current takes a value between I0 and I1, is approximated by a dot line 3. Quantity of light to be produced from the LED is then calculated according to the approximate characteristic of a line graph comprising the dot lines 2, 3. When the driving current is in a section between 0 and I0, required quantity of light P is set according to a formula (P0/I0)/I, whereas when the driving current is in a section higher than I1, driving current I for the required quantity of light P is set according to a formula P0+{(P1-P0)-(I1-I0)}(I-I0).
