A water injection foaming devolatilizing method, and an apparatus for practicing the method according to the invention are designed as follows: A molten polymer material is kneaded in a water-injection dispersion zone (11) of an extruding machine having a pair of screws (6) each of which is turned in the same direction. Water is supplied to the molten polymer material, thus the water being dispersed therein while the molten polymer material is kneaded. In a devolatilizing zone (12) downstream of the water-injection dispersion zone, the volatile components in the molten polymer material are removed by being gasified together with the water. In this water injection foaming devolatilizing method, the molten polymer material is smoothly extruded from the filling zone (10) to the water-injection dispersion zone (11), and in the latter zone (11) water injection is performed with increased pressure due to the aid of a ring (15), thereby to achieve the devolatilizing of the molten polymer material.

While resin forming material and hygroscopic wood flour or wood flour containing water, which were fed to the feed port 23 of the intermeshing type two screw type screw side feeder 20, are being conveyed toward the intermeshing type twin screw extruder 1, they are somewhat kneaded and then introduced into the intermeshing type twin screw extruder 1. Resin forming material and hygroscopic wood flour or wood flour containing water, which have been introduced into the intermeshing type twin screw extruder 1, are melted and kneaded by the heat transmitted from the heating cylinder 2 and also by the heat generated in the process of shearing conducted by the rotating screws 3a, 3b. After that, they are extruded from the die 9 in the form of strands. Moisture and gas composed of volatile components generated in the process of melting and kneading are sucked by vacuum from the rear vent 6a arranged on the upstream side of the introducing port 5 and also sucked by vacuum from the vents 6b, 6c arranged on the downstream side of the introducing port 5, so that they can be discharged outside the apparatus.

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 power supply device includes a battery and processing circuitry. The processing circuitry is configured to estimate a tendency of consumption of the battery and put the power supply device into one of a first state in which the power supply device can supply electric power to another device and a second state in which the power supply device can receive electric power from said another device, in accordance with the tendency of consumption of the battery estimated.

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.
