Filed: 1982-11-10
Abstract: PURPOSE:To increase battery performance by anodically oxidizing an electrode such as nickel, titanium in an acidic bath containing a cobalt salt and heating a material obtained and using it as a positive active material of a nonaqueous electrolyte battery. CONSTITUTION:A nickel plate is anodically oxidized in a cobalt nitrate solution by using a platinum plate as a counter electrode, and a material obtained is heated at 800 deg.C and more and ground in fine powder.

Abstract: PROBLEM TO BE SOLVED: To obtain a stabilization method in which an optimum phase-shift amount can be decided safely over the whole region of an impedance measuring range by a method wherein, when a measuring system is constructed, three known impedances are connected sequentially and the phase characteristic of a feedback loop is measured. SOLUTION: For example, a first measurement-standard is connected to a measuring terminal, a switch 36 is changed over to the side of an injection power supply, and a null loop is opened. In addition, a switch 14 is changed over to the side of a ground, the transmission characteristic of the null loop is measured, and a first transmission characteristic is obtained. Then, the switch 36 and the switch 14 are returned to their original positions, and a variable phase shifter at a narrow-band high-gain amplifier is set on the basis of the phase-shift value of the transmission characteristic value in such a way that the total phase-shift amount of the null loop becomes 180 deg.. Then, an impedance is measured so as to calibrate the impedance.  In this manner, three arbitrary known impedances are connected sequentially, and the one-round phase characteristic of the null loop is measured three times. Thereby, a one- round phase characteristic with reference to an arbitrary impedance to be measured is grasped completely, and an optimum phase compensation amount is computed over the whole range of a measuring value.
