Title: Production of composite pipe
Inventor: TAKEUCHI HIROKIMI
IPC: B23K35/362
Filed: 1985-11-02
Abstract: PURPOSE:To stably produce a wire for welding having a flux made of a compsn. uniform in the longitudinal direction in the stage of producing a flux-cored wire for welding by pelletizing part or the whole of a flux raw material to a specific shape and size, packing the pellets into a metallic strip formed to a channel shape and butt-welding both transverse ends of the metallic strip. CONSTITUTION:Both ends of the belt-like metallic sheet such as steel sheet are bent upward to the channel shape in the stage of producing the flux-cored wire for welding. Part or the whole of the plural powdery fluxes are wet kneaded with an ag. soln. of org. and inorg. binders such as sodium alginate, CMS and sodium silicate and are pelletized to the shape satisfying the following formula: 1<=l/d<=4, lmax<=D/4 (where l is the major diameter of the particles, d is the minor diameter, max is the max. major diameter, D is the inside diameter of the tubular body). The particles are then dried to remove moisture and are packed into the channel shape part of the metallic strip. Both ends of the channel shape are butt-welded to form the tubular body; thereafter, said body is drawn and the composite pipe as the welding wire having the uniform compsn. of the flux in the longitudinal direction is produced.

Title: Measuring method for non-embryo type cytochrome p450
Inventor: KUBOTA TAKAHIRO
IPC: G01N33/53
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To enable measurement of non-embryo type cytochrome P450 without sampling liver cells by performing immunity measuring using the antigen body reaction of the anti-nonembryo type cytochrome P450 antibody with non-embryo type cytochrome P450, and measuring the non-embryo type cytochrome P450 in the serum. SOLUTION: Immunity measuring is performed using the antigen-antibody reaction of the anti-nonembryo type cytochrome P450 antibody with non-embryo type cytochrome P450, and the non-embryo type cytochrome P450 contained in the serum is measured. The P450 to be measured is not restricted particularly, but the P450 belonging to the 3A family of human type is favorable. To measure P450 of 3A family, it is preferable of using an antibody whose mating antigen is P450 of 3A family. Because the antibody corresponding to 3A family makes intersecting reaction with various sorts of P450 belonging to 3A family, it is possible to measure P450 belonging to 3A family using antibody prepared with either P450 belonging to 3A family used as immunity source.

Title: Optical receiving circuit
Inventor: TAMURA TAKAFUMI
IPC: H04B10/69
Filed: 1987-09-29
Abstract: PURPOSE:To enlarge the dynamic range of an optical receiving circuit by lowering the input impedance of a pre-amplifier to amplify the output of a photo- detecting element when the incoming intensity of an optical signal is strong. CONSTITUTION:An output signal to correspond to the incoming intensity of the optical signal is inputted to an equalizing amplifying part 4. An AGC control voltage from an AGC circuit 5 has a characteristic to be increased with accompanying the increasing of the output voltage of the equalizing amplifying part 4 and the operating condition of transistors 8 and 9 is controlled. When the incoming intensity of the optical signal is weak, since a base potential is low, the transistors 8 and 9 go to a shutdown condition. Reversely, when the incoming intensity is strong, the transistors 8 and 9 go to an active condition and since a collector current is respectively flown, the input impedance of a pre- amplifying circuit 2 is lowered. As the result, since the saturation of the pre- amplifying circuit 2 is avoided, the dynamic range can be enlarged.
