Abstract: PURPOSE:To obtain an image pickup picture with matched white balance by providing an image pickup means, a shutter means controlling the supply of light from a light source to the image pickup means so as to open/close the shutter means based on a signal in response to the blink of a blinked light source. CONSTITUTION:An output of a photometric circuit 10 is smoothed by a smoothing circuit 15 and reaches a voltage of a reference voltage Vref 2 or over and is given to a comparator 16 and its output goes to a low level. When the output signal of a filter 14 reaches a Vref 3 or over, an output of a comparator 17 descends to a low level and a flip-flop 19 is in the state of clock input. With a shutter switch SW 2 turned on, an output from a clear terminal of the flip-flop 19 goes to a low level. Then a shutter open signal at the input point of time of the initial clock signal is given from a terminal Q to a control circuit 12 and the shutter is opened. Since the shutter is opened in the white balance state based on the averaged measured value of lens incident light of a color measuring circuit 9 and the photometric circuit 10, proper image pickup is attained.

Abstract: PURPOSE:To bury an opening section flatly by executing electroless plating of a device, which is obtained by forming a first wiring layer and an inter-layer insulating film onto an IC substrate and shaping the opening section communication with the first wiring layer to the inter-layer insulating film, in a reduced pressure atmosphere. CONSTITUTION:An SiO2 or PSG insulating film 2 is formed onto an IC substrate 1, and a first wiring layer 3 is shaped onto the insulating film 2. A first wiring pattern is formed through phtolitho-etching. An inter-layer insulating film 4 is shaped onto the first wiring layer, and an opening section 5 communicated with the first wiring layer 3 is formed. Pd is vacuum-deposited onto the whole surface as a resist used for the photolitho-etching is left as it is, and Pd in an unnecessary section is removed through lift-off. Consequently, the activated layer 8 of Pd is shaped onto the first wiring film in the opening section. An Ni plating layer 9 is buried and formed so as not to shape a stepped section with the inter-layer insulating film 4 in the opening section 5 through reduced pressure electroless plating. Since the inside of a chamber is kept under the state of evacuation at that time, hydrogen bubbles generated during a plating reaction are gotten rid of rapidly. Lastly, a second wiring layer 6 is formed onto the Ni group plating layer 9 and the inter-layer insulating film 4, and the wiring layer 6 is wiring-patterned through photolitho-etching.

Abstract: PURPOSE:To vary damper effect by providing a braking chamber for accommodating one end of a shaft, the other end of which is fixed to a fixed board supported by an air spring device, a magnetic fluid accommodated in the chamber, means held thereon and a magnet for applying magnetic field to a magnetic fluid. CONSTITUTION:When a fixed board 1 is placed in a reference position, most of a magnetic fluid 4 is accommodated in the interior of holding means 5. As the fixed board 1 is supported in the reference position by a separate air spring device 10, load of the fixed board is not applied to the fluid 4. On the other hand, a magnet 6 gives magnetic force for attracting the fluid 4 to the vicinity of a magnetic pole 6a, so that braking force is applied to a shaft 2 through the holding means 5 and the disc 2 to rest in a position shown in the drawing. Further, when exciting current I applied to a coil 6b is increased, magnetic power applied to the fluid 4 changes to increase the viscosity of the fluid 4. Accordingly, in the illustrated reference position, a damper effect is slightly decreased, and when the fixed board 1 is dislocated from the reference position, a damper effect is increased to improve the vibration isolating performance of the device 10.
