摘要： PROBLEM TO BE SOLVED: To provide a technology for lengthening a time for backup and reducing man-hours for maintenance in an interruptible power supply device. SOLUTION: In the interruptible power supply device, a secondary battery and an electric double layer capacitor are used as energy accumulation means; circuits each connected in series with a reverse-flow prevention element such as a diode are connected to each other in parallel; and, during the discharge voltage of the electric double layer capacitor is higher than the discharge voltage of the secondary battery when the power of an AC power supply is lowered, the power of the electric double layer capacitor is fed to a load side by turning on the reverse-flow prevention element at the electric double layer capacitor side, and when the discharge voltage of the electric double layer capacitor is lowered to be lower than the discharge voltage of the secondary battery, the power of the secondary battery is fed to the load side by turning on the reverse-flow prevention element at the secondary battery side.

摘要： PROBLEM TO BE SOLVED: To prevent the generation of latching-up so as to be capable of applying power supply voltage at the same timing as ICs. SOLUTION: A P-channel MOS transistor 4 is connected to a 5-V voltage supply connection terminal 1, and the P-channel MOS transistor 4 is kept OFF until the voltage of a 3.3-V voltage supply connection terminal 2 has risen, so that no 5-V voltage is applied to the power supply terminals of CMOS IC7 and CMOS IC8. When the voltage of the 3.3-V voltage supply connection terminal 2 rises, 3.3-V voltage is applied to the power supply terminals of CMOS IC9 and CMOS IC10. At the same time, 3.3-V is applied to the base of an N- channel bipolar transistor 6, so that the N-channel bipolar transistor 6 is turned on, and 5-V voltage is applied to the power supply terminals of the CMOS IC7 and CMOS IC8. Therefore, at the same time, a power supply voltage is applied to the power supply terminals of CMOS IC7, CMOS IC8, CMOS IC9, and CMOS IC10.

摘要： PROBLEM TO BE SOLVED: To detect deterioration of each sealed lead battery of set batteries. SOLUTION: The case has detection terminals 6, 6', 7, 7' to be connected to electrode plates 4 and 5 of batteries 2 and 3 respectively. For grasping the deterioration condition of each sealed lead battery, the voltage between the positive and negative electrodes of the battery and the voltage with current of a prescribed value running between the electrodes are compared, and the deterioration of the battery is detected by the difference in voltage. Therefore, recycling and discarding of the batteries constituting the set batteries can be prevented.

摘要： PURPOSE:To eliminate a need for an impedance-matching resistor to a circuit board by a method wherein the impedance of an integrated circuit is changed for impedance matching. CONSTITUTION:One end of a resistor 8 is connected to an input line 4 through a fuse 7, and the other end is connected to a GND line 6. When the fuse 7 is not blown, the input line 4 is connected to a GND through the resistor 8 to set a terminated state. In addition, when the fuse 7 is blown, the input line 4 is cut off from the GND. In order to blow the fuse, an overvoltage higher than that in an ordinary state is applied to the input line 4, and a large current is made to flow to the fuse 7. Thereby, whether a terminating resistor is to be installed or not in the input line 4 for a logic part 3 can be decided freely by a user.
