摘要： PROBLEM TO BE SOLVED: To provide a power controller which is capable of sufficiently lengthening the duration of power supply from a power supply unit in service interruption in commercial power. SOLUTION: The power controller comprises a power failure judging means 11, a first power save mode establishing means 12, and a second power save mode establishing means 13. The power failure judging means 11 judges whether power failure detection by a power failure detecting portion has continued for a predetermined time or longer. If the power failure judging means 11 judges that power failure detection has continued for the predetermined time or longer, the first power save mode establishing means 12 establishes first power save mode. In the first power save mode, power supply to a load drive circuit is turned off, and the output voltage of a switching power supply is controlled to a first value. If the power failure judging means 11 judges that power failure detection has continued for a predetermined time or longer after the establishment of the first power save mode, the second power save mode establishing means 13 establishes second power save mode. In the second power save mode, power supply to a sensor is turned off and the output voltage of the switching power supply is controlled to a second value. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide a self-holding solenoid valve driving device hardly causing abnormalities at opening and closing a valve even if a valve element is braked due to the interpolation of an adhesive foreign matter, and the operation of a movable iron core slows down.
SOLUTION: A voltage generating circuit for generating a voltage applied to a coil of the self-holding solenoid valve generates such a voltage that a constant value of a current energized to the coil is set to an upper limit within a current range where an elastic force of a spring applied to the movable iron core becomes larger than a magnetic force applied to the movable iron core by a synthetic magnetic field comprising a magnetic field generated by the coil and the magnetic field of a permanent magnet, when the movable iron core is driven in a direction of pulling the core out of a cylinder case. Thereby, even if the valve element is braked due to the interpolation of the adhesive foreign matter such as scales, and the operation of the movable iron core slows down, the movable iron core is pressed in the pull-out direction continuously for a longer period of time than before. Thus, there is a high possibility that the movable iron core can finally reach a position having no influence by the magnetic force of the permanent magnet, thus hardly causing abnormalities at opening and closing the valve.
