Title: Capacity restoring method for lead acid battery
Inventor: YONEZU KUNIO
IPC: H01M10/42
Filed: 1981-02-27
Abstract: PURPOSE:To restore a battery or a cell by a simple method, and enable it to be used for a long time by reversing the polarity of the terminal voltage of a lead acid battery, which has a positive grid made of a Pb-Ca-Sn system alloy, through compulsory discharge when the capacity of the said battery is reduced. CONSTITUTION:In a lead acid battery prepared by using a Pb-Ca-Sn system alloy as a positive grid, the polarity of the terminal voltage is reversed through compulsory discharge when the capacity of the battery is extrememly decreased. For instance, a number of cells are connected in series, and are subjected to short circuit and discharge by means of a resistor before they are charged. By the means mentioned above, PbO and PbSO4 generated within the positive plate during the use of the battery are reduced to Pb owing to discharge carried out after the reversion, and the electrcial and mechanical connection between the grid and the positive material is improved due to the disappearance of the barrier of the positive plate. Consequently, owing to the restorartion treatment, the capacity of a battery made of a Pb-Ca-Sn system alloy is stabilized.

Abstract: PURPOSE:To obtain a large modulation degree for read signals with even a prepit depth of lambda/8 by reading with the out-of-focus detecting means an information previously recorded on an information recording medium using an extracted light in focus in an asymmetric condition. CONSTITUTION:The other laser beam L (for the out-of-focus detection system) separated with a half-mirror 7 comes to a knife edge 15 (light extracting member) where components of light that pass through an off-axis region only are extracted. The extracted light, after passing through the second projector lens 16, comes to photodetector cells 17a and 17b of the second photodetector 17. The said knife edge 15 stops the light on either front or rear side with respect to the direction a tracking guide extends (or front or rear side with respect to the direction the light passes through a prepit P successively). Signals from photo-detector cells 17a and 17b are fed through a subtracter 18 and a low-pass filter 19 to out-of-focus detection corrector section 20. Thus out-of-focus detection in the knife edge method is performed.
