Title: Fuel supply device for circulating type carburetor
Inventor: MINOURA MIKIO
IPC: F02M17/06
Filed: 1995-12-29
Abstract: PROBLEM TO BE SOLVED: To prevent engine starting failure caused by such a state that fuel in a fuel tank leaks out from a supply pump and flows out into the fuel chamber of a carburetor when fuel tank inner pressure is increased during an engine stopping period, and also a part of fuel flows out into an intake pass through a main nozzle during the engine stopping period. SOLUTION: Fuel supplied by a supply pump 15 is made to overflow a fuel chamber 6 so as to form a constant oil level, and the overflowed fuel is returned to a fuel tank 29 by a discharging pump 47. A diaphragm type automatic cock 31 opened by the discharge pressure of the supply pump 15 when an engine is operated, is arranged between the supply pump 15 and the fuel chamber of a carburetor so that fuel tank inner pressure is made to act upon the rear surface of a diaphragm 32. When the cock 31 is closed, a valve member side pressure receiving area is diminished more than a diaphragm rear surface side by the part of the area of a valve member, and the diaphragm 32 is energized on a closing side by pressure difference, therefore, fuel can be prevented certainly from being led to flow out into the fuel chamber 6.

Title: Image pickup device
Inventor: IWANAGA MASAKUNI
IPC: H04N5/335
Filed: 1996-12-17
Abstract: PROBLEM TO BE SOLVED: To provide an image with high resolution even when a solid-state image pickup element with a small pixel number is in use. SOLUTION: A control means controls drive of 1st and 2nd electromagnetic actuators 32, 62 to tilt a 1st parallel plate 31 at an interval of four times of exposure thereby deviating the image of an object in four directions and to tilt a 2nd parallel plate 61 at an interval of one exposure thereby deviating the image of the object in four directions, and image data obtained by four times of the exposure are synthesized into synthesis image data of one pattern. Since pixels are interpolated by the 1st parallel plate 31, even when a solid-state image pickup element 29 with a small pixel number is in use, an image with high resolution is obtained and since the 2nd parallel plate 61 acts as a low pass filter, deterioration in the image quality due to moire or the false color signal produced by a high frequency over the Nyquist frequency is prevented and excellent image are obtained.
