Inventor: MIYAZAKI TAKESHI
IPC: C07K16/00
Filed: 1993-08-19
Abstract: PURPOSE:To obtain a highly active hydrophobic antibody reduced in agglutination and denaturation. CONSTITUTION:An antibody is reacted with an N-acyloxysuccinic acid imide-3- sulfonic acid alkali metal salt of the formula (R is an alkyl, an aryl; M is alkali metal) in an aqueous medium at 0-80 deg.C, preferably 4-40 deg.C, for 10min to 72hrs, preferably 1-24hrs, to obtain a hydrophobic antibody. The hydrophobic antibody can be used as an immunological diagnostic agent as such or after purified by a dialysis method, ultrafiltration method, gel filtration method, etc., because of having good hydrophobicity and high activity, thereby enabling highly accurate diagnosis. Since the antibody is liable to cause agglutination by the antigen-antibody reaction of the antibody, the accuracy of antigen detection is enhanced.

Title: Method for discriminating coke against ore on surface of material charged into blast furnace
Inventor: IIDA OSAMU
IPC: G01N22/00
Filed: 1992-07-31
Abstract: PURPOSE:To discriminate the iron ore and coke of charged material and to make it possible to detect the distribution thereof by measuring the strength of the received wave of a mu-wave, which is cast on the surface of charged material in a blast furnace and reflected, and obtaining the strength value of the received wave, which is corrected based on the distance to the charged material. CONSTITUTION:A lance 16 is horizontally moved in the direction of the radius in a furnace. Under this state, a mu-wave is emitted from an antenna 7 on the charged material in the furnace. The level change of the charged material in the direction of the radius of the changed material is measured based on the time until the wave is reflected from the surface of the charged material and returned. The raw data of the strength of the mu-wave is measured at the same time and inputted into an operator. A central coke layer 5 is formed on a coke layer 4, which is charged into the blast furnace. An ore layer 3 is formed around the layer 5. When the distribution of the change in strength of the received wave is obtained based on the raw data in the direction of the raius, the effect caused by the distance to the charged material and the effects of the coke and the iron ore of the charged material are synthesized. Therefore, the distribution of the received wave depending on only the difference between the coke and the iron ore is obtained by offsetting the effect caused by the distance from the distribution of the obtained raw data of the strength of the received wave.

IPC: H04B1/26
Filed: 1987-08-19
Abstract: PURPOSE:To improve the noise figure of a mixer by connecting an electrolytic capacitor in parallel to an input line from a port for local oscillation signal. CONSTITUTION:In an output side of a transmission line transformer 18, to an input line to a mixer part 14 from a port 6 for local oscillation signal, a non-polarized electrolytic capacitor 22 is connected in parallel. As for the electrolytic capacitor 22, its impedance becomes high against a high frequency component such as a local oscillation signal L0, and on the contrary, its impedance becomes low against a low frequency component such as 1/f noise, therefore, the input line from the port 6 for local oscillation signal becomes near a short circuit state against the noise component of a low frequency. In such a way, it is prevented that the noise component concerned goes into a mixer part 14 and brought to mixing therein.

Filed: 1987-08-19
Abstract: PURPOSE:To obtain an extremely smooth and little wavy interpolation curve by selecting clothoid curves, connecting some of these and making a tangent direction and a curvature on the connecting points continuous. CONSTITUTION:When the coordinates of two points P1 and P2, and a curvature Cv1 and a tangent direction phi1 of the P1 pint are given, one or two clothoid curves to pass these two pints can be drawn. When the position of the P2 point is reasonable, one, and when it is an unreachable position, two clothoid curves are connected as the continuity of a CV and a phi. Even at the time of more than three point, when a point spring itself is smooth, they can be connected by one clothed. Thus, for example, when an illustrated point string 1-12 is given, these points can be connected. On a figure to show the broken-line of the CV to obtain a first approximate value, one straight line is equivalent to one clothoid. The first approximate value of the CV makes the curvature of a circle passing three points including the front and the rear points into the curvature of the point. A circular interpolation is executed to one part between points 5 and 6 and a straight-line interpolation is executed to one part between points 11 and 12.
