Title: Ultrasonic flowmeter
Inventor: UMEZAWA SOHEI
IPC: G01F1/66
Filed: 1987-07-16
Abstract: PURPOSE:To measure a flow rate without being affected by a disturbance of a flow velocity distribution, by measuring flow velocity at several points on a straight line crossing a flow to determine a flow rate based on an average flow velocity determined from the flow velocity distribution obtained. CONSTITUTION:A first vibrator 1 and seven second vibrators 2a-2g are mounted on the outer wall side of an upright tube section A provided in the course of a flow. The first vibrator 1 and the second vibrators 2a-2g are arranged at a position symmetrical to the center axis of the upright tube section A. The second vibrators 2a-2g as receiving vibrator are arranged on extensions of seven parallel lines Y1-Y7 crossing a straight line T at flow velocity measuring points a3-a-3. Thus, flow velocity is measured by a Doppler method at these several flow velocity measuring points to obtain a flow rate based on an average flow velocity determined from a velocity distribution of flow obtained from the resulting flow rate values.

IPC: F02M45/06
Filed: 1981-11-06
Abstract: PURPOSE:To aim at obviation of the occurence of knocking inherent in a Diesel engine as well as improvement in thermal efficiency, by feeding a combustion chamber with a small quantity of fuel for ignition with the aid of an ignition plunger installed in a plunger chamber and, in turn, feeding the combustion chamber with the main fuel from just in time of igniting. CONSTITUTION:Forming a plunger chamber 3 inside a pump body 2, a main plunger 6 for main fuel-injection use and an ignition plunger 7 for ignition fuel- injection use are so installed as drivable for forward and backward movements. And, discharge starting drive-timing for the ignition fuel of the ignition plunger 7 is set up so as to go ahead of the said timing of the main fuel of the main plunger 6. With this, since it means that ignition is achieved by using a spark of the ignition fuel as a flash point, the accumulation of fuel in a period of ignition delay time becomes decreased so that knocking inherent in a Diesel engine does not happen any longer. And, in as much as injection time for the main fuel is shortened, thermal efficiency is improved.

Abstract: PROBLEM TO BE SOLVED: To rapidly subject livestock dung based excretion sewage to a decomposition treatment of org. matter by utilizing the decomposition effect of soil bacterium groups and to utilize the resultant treated water as liquid manure. SOLUTION: This process decomposes the org. matter by subjecting the livestock dung based excretion sewage to an exposure treatment in single or plural tanks in the presence of the soil bacterium groups. In such a case, far IR radiation ceramics of >=80% and <100% in emissivity at ordinary temp. of far IR rays having a wavelength 6 to 12 μm is immersed into the treated water to aerate the treated water while the soil bacterium groups are maintained in the intermediate state of the anaerobic environment and the aerobic environment. The culture and proliferation of the soil bacterium groups are promoted by the effect of the mineral compsn. derived from the far IR radiation ceramics, by which the org. matter is decomposed.  The sludge contg. the soil bacterium groups having the high decomposability of the resultant cultured and proliferated org. matter is separated from the treated water and is returned to the stage for the aeration treatment of the livestock dung based excretion sewage. The treated water which contains the mineral components extracted from the far IR radiation ceramics and the metabolites of the soil bacterium groups and is usable for a liquid manure is obtd.

Filed: 1999-06-24
Abstract: PROBLEM TO BE SOLVED: To provide a solid state image pickup device capable of automatically switching the linear transformation operation and logarithmic transformation operation of an electric signal corresponding to incident light upon a solid state image pickup element in accordance with the brightness of a subject whose image is to be picked up. SOLUTION: When the luminance of a subject detected by a detection element 4 is larger than a certain fixed value (e.g. 700 cd/m2), a switching judgment circuit 5 judges that an area sensor (solid state image pickup element) 3 is allowed to execute logarithmic transformation operation. A switching signal is sent from a switching signal generation circuit 6 on the basis of the judgment of the circuit 5 and the area sensor 3 executes the logarithmic transformation operation. When the luminance of the subject is smaller than the fixed value (e.g. 700 cd/m2), the circuit 5 judges that the sensor 3 is allowed to execute linear transformation operation. Thereby a switching signal is sent form the circuit 6 on the basis of the judgment of the circuit 5 and the sensor 3 executes the linear transformation operation.
