摘要:
The invention is related to antibodies which specifically react with connective tissue type-human mast cells, a production method of the antibodies, hybridomas which produce the antibodies, a production method of the hybridomas and antigen proteins recognized by the antibodies. After cord blood cells were cultured in the presence of SCF and IL-6, they were further cocultured with primary culture of human skin fibroblasts, and connective tissue type-human mast cells were thus obtained. A rat was immunized using the cells, hybridomas were prepared and selected by an ordinary method, and novel monoclonal antibodies were harvested from the culture supernatant of the selected hybridomas. The monoclonal antibodies specifically reacted with connective tissue type-human mast cells.

An exhaust gas cleaning device is disposed within an exhaust pipe connected to the exhaust port of an internal combustion engine. The exhaust gas cleaning device comprises an inner pipe disposed coaxially within the exhaust pipe with an annular space defined therebetween, the inner pipe being provided with a plurality of perforations, and laminated structures disposed upon the inner and outer surfaces of the inner pipe and including a catalyst for cleaning unburned components of the exhaust gas flowing within the exhaust pipe, each of the laminated structures being formed of a material which is not deleterious to the catalyst. The laminated structure includes a catalyst carrier layer formed by, in accordance with one method, fusibly injecting a catalyst including a solution onto an intermediate layer formed upon the inner and outer surfaces of the inner pipe and drying the same so as to remove the liquid component therefrom. The laminated structure may also be formed upon the inner surface of the exhaust pipe so as to improve the exhaust gas cleaning effect.

A communication structure provided in a steering wheel. The steering wheel includes having a steering shaft; a boss fixed to it. At least one spoke fixed to the boss. A pad is installed relatively rotatably to the steering shaft at a position more proximate to the driver than the boss. A column is positioned in relation to the pad so that at least one of the spoke and a boss plate is sandwiched therebetween. At least one set of magnetic communication units composed of a receiving unit and a transmitting unit is provided on the pad and said column, at least one of which consists of a core and a coil wound thereon.

A first multi-port hybrid coupler is formed by n2.sup.n-1 (where n is an integer equal to or greater than 2) hybrid couplers alone, which are divided into n stages, each including 2.sup.n-1 hybrid couplers. A signal input to any one of N (=2.sup.n) input terminals of the first stage is distributed equally to N output terminals of the nth stage. The N output terminals of the nth stage of the first multi-port hybrid coupler are connected to N amplifiers at the input side thereof, respectively, and the N amplifiers are connected at the output side to a second multi-port hybrid coupler. The second multi-port hybrid coupler is identical in construction with the first multi-port hybrid coupler, but its input terminals and output terminals are reverse from those of the latter and the input terminals of the second multi-port hybrid coupler are connected to the N amplifiers in an order reverse from the order of arrangement of the output terminals of the first multi-port hybrid coupler.

A radio apparatus forming a radio network system calculates a calculated distance, based on a tentative self-position and tentative positions of a plurality of radio apparatuses existing in the vicinity. The radio apparatus successively and autonomously corrects the tentative self-position so that the calculated distance comes closer to the measured distance, relying more heavily on the calculated distance than the measured distance between itself and each of the plurality of radio apparatuses, and determines the position of itself. Other radio apparatuses also successively correct the tentative self-positions by the same method as the radio apparatus, and determine the positions of themselves.
