Title: Detection of degradation state of seal lead battery
Inventor: KUDO AKIHIKO
IPC: G01R31/36
Filed: 1989-03-10
Abstract: PURPOSE:To detect the degradation of a seal lead battery by measuring the internal impedance with <10Hz frequency. CONSTITUTION:The internal impedance of the seal lead battery is measured with <10Hz frequency, and this value is compared with the initial value. This method uses the fact that the internal impedance of the seal lead battery measured with <10Hz frequency is increased in accordance with degradation. It is considered that the impedance due to diffusion of an electrolyte is included in the internal impedance in this frequency range, and it is assumed that diffusion of the electrolyte to active materials is degraded by conversion of active materials to lead sulfates at the time of the degradation of the seal lead battery. Since the internal impedance is measured with <10Hz frequency with a charging voltage applied, the degradation state is detected without interrupting charging of the seal lead battery.

Title: Circuit diagnosis apparatus
Inventor: AKIYAMA SHIZUO
IPC: G01R31/316
Filed: 1982-04-08
Abstract: PURPOSE:To diagnose a signal processing circuit in real time basis by time compressing signals to allow the insertion of diagnosis data in a vacant time. CONSTITUTION:Signals CH1-CHn inputted through multiplexer 121-12n and an A/D converter 13 are read out of a memory 14 being time compressed. A sine wave signal S as diagnosis data is read out in the vacant time of these signals, for example, between the signals CHn and CH1 and fed to a variable filter 16 through a D/A converter 15. This signal is fed to a decision circuit 18 with a diagnosis timing signal outputted from a control circuit 17. In this decision circuit 18, the sine wave signal outputted from the variable filter 16 is converted to pulse signal and counted. As abnormality in the variable filter 16 causes a change in the amplitude of the sine wave signal, the count value differs from a reference value. This enables the diagnosis of the variable filter 16 in real time basis.

Abstract: PROBLEM TO BE SOLVED: To control magnetoresistance response to a magnetic signal by a method wherein a constrained ferromagnetic layer, having a side part circumfer ence which is not extended over the side part circumference of an insulating tunnel layer, is retained within the another spaced plane surface without overlap ping with an insulating tunnel layer. SOLUTION: Write in an MJT is attained by allowing a current to flow through the upper and lower electrode wiring layers on the memory cell application of a magnetic tunnel junction MTJ element. When a sufficiently large current is allowed to flow through the above-mentioned lines, the magnetization direction of a free ferromagnetic layer 32 is rotated in reverse parallel from parallel to the magnetization direction of a constrained ferromagnetic layer 18 by the coupled magnetic field formed in the vicinity of a free ferromagnetic layer 32. Current level is selected in such a manner that the coupling magnetic field to be formed exceeds the switching field of the free ferromagnetic layer. The magnetic field formed by a coupling write-in current is selected smaller than the magnetic field required for rotation of the magnetization direction of the constrained ferromagnetic layer.
