Title: Air straightening device for bow part
Inventor: OGAMI TAKAHIRO
IPC: B63B1/32
Filed: 1986-04-17
Abstract: PURPOSE:To reduce the resistance of a ship so as to improve its propulsive performance and fuel consumption performance, by equipping the ship with an air straightening plate, which protrudes almost horizontally from the external surface, in the upper from an anchor bell mouth of the external surface in the bow part within the maximum beam of the ship so that it straightens a flow of air to prevent an eddy current. CONSTITUTION:In the upper from an anchor bell mouth 3 of a bow part external surface 5, a ship 1 provides a fixed type air straightening plate 4 to be horizontally protruded so that it surrounds the external surface 5, and the ship 1 is equipped with said plate 4 within the maximum beam. Then the ship 1, when it is in sailing, allows air to flow along the bow part external surface 5, and the air, which is straightened by the air straightening plate 4 to flow rearward, is prevented from exfoliating in an outer shell upper end part 2. Accordingly, generation of an eddy current can be surely prevented by inhibiting a flow of the air from exfoliating in the ship outer shell upper end 2. Consequently, the ship 1, which eliminates the action of resistance force as caused by the eddy current in the past, enables propulsive performance and fuel consumption performance to be improved by reducing the resistance of the ship.

IPC: B01D21/02
Filed: 1979-07-16
Abstract: PURPOSE: To make the velocity of flow in an oblique plate apparatus uniform and make precipitation efficency higher by obliquely providing the oblique plate apparatus, as well as by providing an inflow port and an outflow port of a suspension, by positioning the same on the side where the sectional area of the flow passages of a flow aligning part is larger.  
     CONSTITUTION: The suspension consisting in mixing a coagulant into feed water under stirring is admitted from an inflow port 12 via a lower flow-aligning part 21 to an oblique plate apparatus 16, where the floc formed precipitates on the lower flow-aligning part 21 and the clean water is discharged from an upper flow-aligning part 20 into a flow passage 15 through an outflow port 14. In this case, the upper and lower flow-rectifying parts 20, 21 are so formed that the sectional areas of their respective flow channels become linearly larger, on the side nearer to the inlet 14, 12; therefore, the velocities of flow of the suspention between the respective oblique plates 17... with respect to the other are uniformalized and the sedimentation of the floc formed is accomplished uniformly in each part. With this constitution, the efficiency of precipitation is considerably improved and since the floc does not flow out to the upper flow-aligning part 20, there is no need for providing any troughs.

Filed: 1979-07-16
Abstract: PURPOSE: To make it possible to measure H 2 O 2  or enzyme peroxide rapidly with high sensitivity by using phenol having a specific substituent for a fluorescent substrate and then by making this phenol, H 2 O 2  and enzyme peroxide react on one another.  
     CONSTITUTION: A solution of a compound such as 4-hydroxyphenylpropyl alcohol expressed by the right formula, a buffer solution and a solution of H 2 O 2  are poured in a fluorescent measuring cell and then enxyme peroxide to be inspected is added and mixed to find a change in fluorescent intensity immediately. Then, the increment of fluorescent intensity per minute is measured and from the standard curve found through the same operation with regard to a known amount of enzyme peroxide, enzyme peroxide to be inspected is measured. To measure H 2 O 2 , the fluorescent intensity after reaction is measured and from the standard curve previously found, the amount of inspected H 2 O 2  is measured. Those fluorescent substances are greater in fluorescent light reaction speed and fluorescent-light intensity than conventional one and while the sensitivity increases more than 20 times, the required time is reduced to less than 1/20, so that they are suitable for enzyme immunity measurement that uses enzyme peroxide.

Title: Radiator fin and manufacture thereof
Inventor: SASAKI SHINICHI
IPC: H01L23/36
Filed: 1983-05-24
Abstract: PURPOSE:To improve partial thermal conductivity in the downstream of a refrigerant by zigzag arranging radiator fin pieces and forming both a front edge section and a rear edge section to the main current of the refrigerant to a wedge shape. CONSTITUTION:Each radiator fin piece 5 can be arranged in the flow 3a of a refrigerant hardly affected by radiator fins on the upstream side by zigzag arranging the radiator fin pieces 5. Consequently, the growth of a temperature boundary layer growing along the wall surfaces of each fin piece 5 can be reduced, and the partial thermal conductivity of the fin pieces 5 positioned at the downstream section of the refrigerant can be improved particularly. The flow 3a of the refrigerant is smoothed by forming both the front edge sections and rear edge sections of the fin pieces 5 to a wedge shape, and the generation of stagnant swirls can be reduced significantly. Accordingly, pressure loss is minimized markedly, and the refrigerant can be flowed at high speed by comparatively small power.

Thus the insulating films 14 and 15 to be the electric load charging channel of MNOS and the Si3N4 film 16 to store the electric load are formed. Consequently the electric load may be easily charged without reducing the holding time capacitating to reduce the write.erase voltage.

Filed: 1991-04-22
Abstract: PURPOSE:To equalize etching by installing a substrate in the vicinity of the resonance point of electronic cyclotron resonance point, and besides, applying FR bias of 40KHz. CONSTITUTION:The high-speed anisotropic etching of an Al metallic film or an Si substrate can be materialized uniformly with single Cl2 gas even on the level of 10<-4>Torr by applying 40KHzRF bias to the substrate installed on an electronic cyclotron resonance point 5. Furthermore, in the etching of Al alloy, it can be etched on the level of 10<-4>Torr, so it also has the effect of post corrosion being hard to occur on the sidewall of a pattern, since the adsorption of Cl2 onto the sidewall is little. Hereby, the high-speed etching on the level of 10<-4>Torr is possible, and complete anisotropic etching can be materialized even with single Cl2 gas.
