A fixed electrode is opposed to the transformable electrode in order to determine a second room between both electrodes, and the transformable electrode moves to the first or second direction according to control of relative voltage difference between the both electrodes. The liquid is discharged into a dielectric material source through an opening in the fixed electrode due to the volume change. A ratio between a cross-sectional area of the opening and circumference of the fixed electrode is larger than 0.25 μm, and preferably about 5 μm.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To suppress the fluctuation of an output terminal voltage of a boosting circuit and to suppress the breakage of the boosting circuit caused by an abnormality of a microcomputer.  <P>SOLUTION: When a power supply voltage of a DC power supply VB (nominal voltage 12V) is lowered to a value lower than a prescribed boosting starting voltage value (9V) when an IG power supply is turned on, the microcomputer 13a outputs a PWM signal, whereby the boosting circuit 10 outputs a voltage obtained by boosting the power supply voltage of the DC power supply VB to an output terminal 21, and when the output terminal voltage value exceeds a Zener voltage value (10V) of a Zener diode Z2 , the boosting circuit stops boosting. When the IG power supply is turned off, the boosting circuit 10 does not perform boosting since an output of the PWM signal is stopped. Furthermore, when the IG power supply is turned off, the Zener diode Z2 is not energized even if the voltage of the DC power supply VB is not lower than 10V since a transistor T2 is turned off. Also in the case that the boosting circuit continues boosting exceeding 10V due to the occurrence of some kind of an abnormality, the boosting circuit stops boosting when the boosting is continued exceeding the Zener voltage value (15V) of the Zener diode Z1.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
