Abstract: PURPOSE:To obtain silver halide emulsion particles having low fogging, high sensitivity, improved granularity and sharpness, and excellent storage property and pressure resistance by adding a thickener to a gelatin having protective colloidal property to thicken the gelatin and using this gelatin having higher viscosity as a disperse medium when silver halide fine crystalls are formed. CONSTITUTION:A silver halide fine crystalline emulsion is prepared by mixing a silver salt soln. and halide soln. in the presence of a gelatin soln. into which a thickener is added. This silver halide fine crystalline emulsion is added to the mother liquid tank containing seed particles which act as the center core for growing and forming emulsion particles. Thus, crystals are grown from the seed particles into emulsion particles. The thickened gelatin soln. is specified to have 10-60cp (at 30 deg.C) for 0.5-5wt.% gelatin concn.

Title: Exhaust gas recycling device for internal combustion engine
Inventor: MATSUMURA TOSHIMI
IPC: F02M25/07
Filed: 1993-12-15
Abstract: PURPOSE:To reduce the amount of EGR(exhaust gas recycled) remaining in an intake system by computing a correction for the variation of a basic command for the amount of EGR, and determining the amount of EGR using a value obtained by correction of the basic command by the correction, when a load variation exceeds a predetermined amount. CONSTITUTION:When an electronic control unit 8 controls the amount of exhaust gas recycled, a basic command for the amount of EGR and a command for the amount of fuel injection are first computed from a throttle opening signal and an engine speed signal. Next, the difference between the current and previous commands for the amount of injection is calculated and compared with a predetermined value to determine whether or not acceleration is under way. A first and second correction are computed based on the basic command and the differential value of the command for the amount of injection, respectively, and a value equal to the addition of both corrections is set as a correction for the basic command. When acceleration is detected, the basic command is corrected using the set correction to provide a final command, for controlling the opening of a negative pressure control valve 7, i.e., an EGR valve 5.

Filed: 1986-12-26
Abstract: PURPOSE:To improve the degree of integration by providing each capacitor of a plurality of memory cells in the side walls of a groove formed in the substrate surface, simultaneously providing a region for isolating adjacent capacitors, and providing in the bottom of the groove a region for mutually isolating all the plural capacitors. CONSTITUTION:After forming an oxide film 102 in part of a silicon substrate 101, an oxide film 103 and a nitride film 104 are deposited, and thereafter the groove opening part is patterned and etched, forming a groove 105. Subsequently, after implanting B<+> ions into the side walls and the bottom of the groove 105, an oxide film 107 is formed. Then, after etching the side walls and the bottom of the groove 105, a nitride film 104a is deposited and etched. Hereupon, the nitride film 104a remains on the side walls, and only the nitride film on the bottom is etched, whereby an element isolation region 102a is formed. Then, after entirely peeling off the nitride films 104 and 104a and depositing a silicon glass film 108, an n<-> type impurity region 109 is formed in the surface of the side walls 105a. Then, after etching the film 108 and the oxide film 103 to form an oxide film 110, a monocrystalline silicon film is deposited on the whole surface, forming a capacitor electrode 111.

Title: Lamination separator for fuel cell with solid electrolyte
Inventor: NAKAGAWA HIROTAKA
IPC: H01M8/02
Filed: 1990-11-22
Abstract: PURPOSE:To provide a separator for lamination free from risk of breakage, etc., and excellent in electroconductivity, processing easiness, and strength by forming it from a composite material consisting of two metal materials joined together - one having a small coefficient of thermal expansion and the other having a large coefficient. CONSTITUTION:A separator for lamination as per invention is made from a composite material consisting of two metal materials - one 1 whose coefficient of thermal expansion is smaller than that of a battery 3-layer film and the other 2, which is resistant against heat, having a larger coefficient than the same and used as separator conventionally. In this manner, the coefficient of thermal expansion as the separator X is set to the middle between the two so as to provide a value near the coefficient of the battery 3-layer film. Because separator X is formed from metal material, this is free from risk of impairing the characteristics as metal separator such as electroconductivity, heat conductivity, processing easiness, and strength. Accordingly there is no fear of breakage while the fuel cell concerned is under service, and the electroconductivity is large and the processing easiness and strength are excellent.

Abstract: PURPOSE:To dispense with the substitution of air at the time of dripping, to eliminate the anxiety of nosocomial infection and to stabilize a dripping speed, in a blow-molded container made of a flexible synthetic resin, by making the shape of the body part of the container flat and bringing the side edge and bottom edge parts of said container to be acute-angle ridgeline. CONSTITUTION:In a bottle like container 1 made of a flexible synthetic resin formed by blow molding, the body part 3 of the container 1 is made flat and both side edge parts 4, 4' and bottom edge part 5 wherein the wide surface of the flattened body part 3 is set to the front are formed into an acute-angle ridgeline. Since this container 1 for an infusion solution is formed so as to have a relatively thin wall, the container has excellent transparency and impurities can be easily discovered. Further, because of a system for dripping content by the deformation of the container, the substitution of air is unnecessary at the time of dripping and, further, a dripping speed is stable and the content can be allowed to flow out perfectly.

Abstract: PURPOSE:To improve a limit air velocity of wind resistant performance by raising a speed of a fan when an air pressure switch senses a reverse air flow, and controlling the speed of the fan corresponding to the reverse air flow until the reverse flow is not sensed at a steady speed. CONSTITUTION:A fan 4 is controlled to a predetermined speed (steady speed) responsive to a burning quantity of a burner 3 at the time of steady burning of a hot water supplying apparatus 1, and an air pressure switch 5 for sensing a reverse air flow is turned ON. When the reverse flow is sensed, the speed of the fan 4 is raised. Thus, when the switch 5 is turned OFF by the reverse flow, the speed of the fan 4 is raised until the switch 5 is again turned ON, i.e., a normal air flow rate is obtained against the reverse flow, and the speed of the fan to meet the strength of the reverse flow is set. Thus, a limit air speed of wind resistant performance can be improved.
