IPC: C07K19/00
Filed: 1994-01-10
Abstract: PURPOSE:To realize a high sensitivity quick measurement by covalent-bonding a compound represented by a specified formula and an immunogenic carrier through a carboxyl group thereof. CONSTITUTION:A compound shown by formula II (n is an integer of 0 to 5) is produced by causing reaction between a cyclohexanone derivative and 2- amino-1-cyclopentane-1-carbonitrile in the presence of ethyl polyphosphate and subjecting a compound thus produced to hydrolysis. A protein, polypeptide or sugar protein, is employed as the immunogenic carrier. They are covalent- bonded through a carboxyl group to produce a composite which is employed as an antigen generating antibody. An animal is dispensed by intravenous, hypodermic or intranasal injection. After dosing with small quantity of antigen, the same antigen is given at a predetermined interval and the whole blood is sampled when the value of antibody in the blood serum is maximized. The whole blood is purified by separating the blood serum and used as an antibody thus measuring the quantity of compound shown by formula I in a sample quickly with high sensitivity.

Abstract: PURPOSE:To avert soldering defects, etc., by removing the lower heater of a zone for soaking, forming an aperture for introducing outdoor air on a lower furnace wall and forming apertures for discharging in-furnace gaseous flow on an upper side furnace wall at both ends in the longitudinal direction of the zone for soaking. CONSTITUTION:The panel heater in the lower part in the zone 23 for soaking is removed. The outdoor air introduced from the aperture formed on the lower furnace wall of the zone 23 for soaking into the furnace is blown to the rear surface of a circuit board as it is and infiltrates upward from the peripheral edge of the circuit board. This outdoor air is led to the outside of the furnace from the apertures 26a, 26b of the upper furnace wall. Both ends of the circuit board heated to the temp. higher than the temp. in the central part in this process is cooled by the outdoor air infiltrating flowing upward. As a result, the fluctuation in the temp. within the plane of the circuit board is lessened and the substrate is uniformly heated over the entire part. The troubles, such as thermal damages and soldering defects of the mounted parts, are effectively averted in a heating zone 24 for regular heating.
