Abstract: PURPOSE:To improve a discharge characteristic under the control of the activation condition of a battery such as high-current discharging or low-temperature discharging by sufficiently activating a secondary battery in a short time through storing the secondary battery for a fixed period at high temperature after the secondary battery is charged. CONSTITUTION:A secondary battery is charged, and then is stored for 7-240 hours (in particular, the degree of 15-72 hours is preferable) at 40-80 deg.C (in particular, 40-70 deg.C are preferable). A nickel-cadmium battery and a nickel-zinc battery, etc., are cited as an applicable secondary battery, and they are suitable, in particular, to activate a nickel-hydrogen battery. Various hydrogen storage alloys can be used as the negative electrode active material, and, in particular, when TiNi alloy containing AB2 Fe is used, this is suitable as negative electrode active material. At that time, a positive electrode, e.g. manufactured by a paste formula by using Ni (OH)2 is used as positive electrode active material, and the hydroxide aqueous solution of alkaline metal such as potassium hydroxide is used as an electrolyte.

Patent JP-H0289417-A (JP)
Title: Test circuit
Inventor: SAGARA MASANAKA
IPC: H03K17/00
Filed: 1988-09-27
Abstract: PURPOSE:To facilitate the detection of a defective dummy transistor(TR) by providing the dummy TR receiving an its inverting signal of a MOS output TR in addition to the MOS output TR to eliminate a switching noise of an IC and connecting a TR for test after the gate of the dummy TR. CONSTITUTION:N-channel MOS TRs 1-n are turned on to store electric charge in capacitors C1-Cn. With a light made incident in, e.g., a photodiode DIm during that time, then the electric charge in the capacitor Cm is being decreased. Moreover, when the TRs 1-n are turned on one by one each as bits, the TR corresponding to the m-th bit receiving the light causes a current to flow from a power supply VDD to the capacitor Cm because the charge in the capacitor Cm is decreased thereby allowing to discriminate whether or not the incidence of light arises. However, when the TRm is turned on, a large noise level is caused to malfunction the circuit. Thus, it is possible to detect a defective TR by abutting a test terminal on the gates of dummy TRs 1', n'.
