IPC: G05F1/56
Filed: 1995-02-20
Abstract: PURPOSE: To provide a power supply circuit whose malfunction is prevented when an AC input voltage drops below a prescribed value. CONSTITUTION: When the output voltage of a rectifier circuit 102 is at a certain voltage or higher, a Zener diode 104 is turned on, a transistor 107 is turned on at this time, and a transistor 110 is turned off. As a result, a constant voltage circuit 111 performs a normal operation. On the other hand, when the output voltage of the rectifier circuit 102 is a certain voltage or lower, the Zener diode 104 is turned off, the transistor 107 is turned off, the transistor 110 is turned on, and the constant voltage circuit 111 becomes a cutoff state. Since a microcomputer 112 is not operated at this time, a transistor 114 is turned off, an electromagnetic relay 116 for a main power supply is turned off, and a voltage is not supplied to a rectifier circuit 117 for the main power supply so as not to be operated.  Consequently, it is possible to prevent a malfunction such as chattering or the like which is generated due to a low voltage.

Title: Positive electrode active material and nonaqueous electrolyte secondary battery
Inventor: SUZUKI SATORU
IPC: H01M4/131
Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery with less deteriorated charging/discharging characteristics even when used under high temperature conditions using inexpensive manganese oxides for a positive active material. SOLUTION: This positive active material has a manganese oxide particle mainly containing a manganese oxide and an elution suppressing layer of a non-polymer film covering the manganese oxide particle for suppressing elution of a manganese. This nonaqueous electrolyte secondary battery has the positive active material in a positive electrode. A nonaqueous electrolyte (an electrolyte solution, for example) is not brought into contact with a manganese element highly active by blocking the elution suppressing layer so that the nonaqueous electrolyte is prevented from being electrolyzed by the manganese. A negative electrode is not badly affected by eluting the manganese from the positive active material.  Therefore, this nonaqueous electrolyte secondary battery can maintain large discharging capacity even if stored or charged/discharged under high temperature conditions for a long time and deterioration of charging/ discharging characteristics is reduced.
