Title: Method for analog-digital conversion
Inventor: KANAI TETSUO
IPC: H03M1/38
Filed: 1982-06-15
Abstract: PURPOSE:To reduce errors at a low input analog signal level, by comparing reference potential corresponding to a binary number obtained by successively shifting ''0'' of a binary number consisting of the maximum digit bit of ''0'' of other bits of ''1'' with an analog signal sequentially. CONSTITUTION:In case of AD conversion of 3 bits, an output consisting of maximum digit bit of ''0'' and other bits of ''1'' is generated from an analog input. In this case, a reference potential generating part 4 selects a dividing resistor for binary ''011'' and reference potential 5 determined by the dividing resistor is compared with an analog input 2. If the analog input 2 is smaller than the reference potential 5, a dividing resistor for binary ''001'' is selected and the reference potential 5 is compared with the analog input 2 similarly. If the analog input 2 is smaller than the reference potential 5, a dividing resistor for binary ''000'' is selected moreover and the voltage are compared. Control for sequential comparison is the same as ordinary technique as shown in the figure.

Abstract: PURPOSE:To prevent leakage, expansion, breakage, and deterioration of battery capacity during conservation of a battery by using perfluoroalkyl-polyoxiethylene sulfate as anticorrosive of zinc alloy for a gel negative electrode. CONSTITUTION:It is constituted by a metal case 2, positive electrode combining agent 3, a separator 4, a negative electrode collector ring 5, a polyethylene-resin sealer 6, a negative electrode bottom plate 7, a positive electrode cap 8, thermal- contraction vinyl chloride 9, and enclosing can 10. In this case, perfluoroalkyl- polyoxiethylene sulfate is used as anticorrosive of zinc alloy for a gel negative electrode 1. A stable anticorrosive coat is therefore formed on a non-hardened and extremely-low-hardened zinc surface. This is because both perfluoroalkyl group of being hydrophobic in the anticorrosive and polyoxyethylene group of being hydrophilic are chemically stable and polyoxyethylene has salfate at the end to allow higher solubility in alkaline electrolyte. The occurrence of hydrogen gas is restrained in zinc corrosion, accordingly. It is thus possible to prevent leakage, expansion, breakage, and deterioration of battery capacity during conservation of a battery.
