    摘要: The invention provides novel processes for preparing efficiently compounds of general formula (1) (wherein R1 and R2 are each independently hydrogen, optionally substituted C1-C10 alkyl, C3-C14 hydrocarbyl bearing alicyclic skeleton, or the like) and initermediates thereof. Compounds of general formula (I) can be prepared by subjecting compounds of general formula (II) and/or salts thereof to cyclization hydrolysis in an aqueous basic solution. Further, compounds of general formula (II) can be prepared from industrially easily available diaminomaleonitrile in a high yield.

    摘要: A rectification device rectifies an input voltage from an AC power source. First and second switching devices are arranged between a pair of output terminals of the rectification device and alternately turned on/off. A series circuit of a first capacitor and an inductor is arranged between the two terminals of one of the first and second switching devices so as to perform a smoothing operation with respect to the frequency of an output from the rectification device. A second capacitor serves to form a resonance circuit in cooperation with the inductor in accordance with the ON/OFF operations of the first and second switching devices. The capacitance of the second capacitor is smaller than that of the first capacitor.

    摘要: According to one embodiment of a DC power supply feeding system, the system includes a DC voltage power supply that outputs a specified voltage by using a commercial AC power supply, a varying voltage power supply that generates power by using natural energy and outputs a varying voltage, and a reverse flow preventing elements that connects the DC voltage power supply and the varying voltage power supply in parallel while output sides are made to have same polarity, and supplies powers obtained from the DC voltage power supply and the varying voltage power supply to a load. When an amount of power generation of the varying voltage power supply is small, the power is intermittently supplied to the load.
