Filed: 1980-06-13
Abstract: PURPOSE: To obtain the power source for a water pump by means of a simple apparatus by installing the rotary disc made of shape memorizing alloy and the shielding plates having the solar beam penetrating part and the impenetrable part arranged alternately, in the captioned apparatus utilizing the solar beam.  
     CONSTITUTION: The rotary disc 1 which consists of the blades 1A and 1B each of which has the rod-shaped shape memorizing alloy 4 at the center and has heat collecting plates 3 arranged on both sides of the center and the shielding plate 2 having the solar beam penetration part 2A and the nonpenetration part 2B arranged alternately are arranged. When the solar beam which penetrates the shielding plate 2 heats the alloy 4 of the blade 1B, a lever 6 revolves, having a fulcrum 7 as a center, because of the elongation of the alloy 4, and a ratchet 8 pushes the tooth of a ratchet wheel 5, and the disc 1 is revoled in the C direction. On the other hand, as for the blade 1A into which the solar beam does not penetrate, the alloy 4 is in contraction state, and the ratchet 8 does not exert any force to the ratchet wheel 5. Therefore, the disc 1 revolves continuously so far as the blades 1A and 1B are irradiated by the solar beam.

Title: Image pickup unit
Inventor: YAMAZAKI YASUYUKI
IPC: H04N5/235
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To obtain a unit which displays an excellent image by adding outputs of plural pixels, changing the number of pixels to be added, and changing a quantity of image pickup light which the pixel receives in a direction that negates change in signal that can be obtained by addition. SOLUTION: In a system control circuit 21, when it is judged from a video signal from an image pickup signal processing circuit 16 that a subject is dark, a CCD driving circuit 14 is controlled so that reading of a CCD 13 is driven. Since the video signal to which a pixel charge is added is outputted when the CCD 13 is driven, a video signal of a level higher by the addition amount is outputted from the CCD 13. In the system control circuit 21, the CCD driving circuit 14 is controlled and an exposure time at the CCD 13 is controlled so that it is in inverse proportion to the level of the video signal higher just by an added amount. Since the level of the video signal to be outputted from the CCD 13 is maintained constant even if the number of pixel to which a charge is added is changed, an image to be displayed on an LCD 19 does not change.
