An autofocus system is provided that includes a focus-verification image-recapturing processor and a focus-verification image display processor. The focus-verification image-recapturing processor sets ISO sensitivity to a value lower than a predetermined value and increases an exposure value by adjusting at least one of an aperture value and an exposure time to carry out a focus-verification image-recapturing operation under focusing conditions applied in an antecedent autofocus operation when ISO sensitivity that is set in said auto focus operation exceeds the predetermined value. The focus-verification image display processor displays a focus-verification image obtained by the focus-verification image-recapturing operation when the ISO sensitivity that is set in the auto focus operation exceeds the predetermined value.

The center of a turntable 30 moves around the central axial line of an autoroation disk 20 along the circular orbit C of a smaller diameter than that of an autorotation disk 20. Thus, the turntable 30 revolves both around a center point O and on its own axis in accordance with an autorotation of the autorotation disk 20. A polishing holder 60 holds a connector of an optical fiber polished by a polishing film 41 arranged on the upper plane of the turntable 30. An optical fiber end face polishing machine provided with a memory 85 for storing a control program which allows a control device 80 to execute predetermined polishing steps, the control device 80 being for controlling an autorotation motor 16 of the turntable 30 and a revolution motor 14 thereof.

A solenoid valve driving apparatus includes switching means for ON/OFF-controlling application of a direct current voltage to a solenoid of a solenoid valve, and signal outputting means. A first period and a consecutive second period are set as a valve opening operation period of the solenoid valve. When the signal outputting means outputs the PWM signal to the switching means, a duty ratio of the output signal is set to be higher in the second period than in the first period so that a power supplied to the solenoid is larger in the second period than in the first period. As a result, a valve opening operation is performed in the solenoid valve reliably, and loud noise generation during the valve opening operation is suppressed.

There is provided a self-excited switching power supply circuit. A cycle control capacitor is charged with a flyback voltage generated in a feedback winding of a transformer during OFF operation period in which an exciting current does not flow in a primary winding of the transformer. An OFF control capacitor the charging speed of which changes ON operation period is charged with the charging voltage of the cycle control capacitor during the ON operation period in which an exciting current flows in the primary winding. The charging voltage of the cycle control capacitor is changed with a periodic cycle Tc sufficiently longer than an oscillation cycle To to make the oscillation cycle To of continuous oscillating operation variable based on the periodic cycle Tc. As a result, the frequency of a harmonic is distributed.

A signal extracting apparatus is provided based on independent component analysis with reference for a single measured signal as a signal processing technique that allows stable and quick extraction of a target signal from single measured signal even in a high-noise environment with a high noise ratio against a target signal to be extracted. The signal extracting apparatus includes: a single-signal measuring unit to measure a measured signal as a single time-series signal containing a target signal obtained by measurement by a single channel; a reference signal creating unit (2) to create a reference signal provided with timing-axis information based on the time-series signal obtained by the single-signal measuring unit; and a main processing unit (5) to perform independent component analysis with reference for a single measured signal by capturing the reference signal obtained by the reference signal creating unit (2) and providing the timing-axis information for an algorithm in a reference system to extract an independent component.
