    摘要: A reaction force actuator 3 for giving reaction force to a steering wheel 2 disengaged from a steering mechanism 1 is provided. A steering control unit 4 is provided to control so that the reaction force decided in accordance with the detected results of the running speed by a vehicle speed sensor 6 and the detected results of a road surface condition by a current sensor 7a, an open air temperature sensor 7b, a wiper switch 7c and a supersonic wave sensor 7d. Also, the steering motor 5 for applying the steering force to the steering mechanism 1 is operated smaller at higher speed and larger at slower speed at running by the operation of the steering control unit 4 in accordance with the detected results of the running speed by the vehicle speed sensor 6. Therefore, the same steering feelings as those of the coupling type steering system are obtained to realize a steering system enabling the reliable steering operation to effect under the various different running conditions. Also, the bother of the steering operation at the slow speed or at the stop time is dissolved by simple construction.

    摘要: The present invention yields a coating film excellent in adhesion, water resistance, solvent resistance and durability. A compound having a carboxyl group and a long-chain alkylthio group or a salt thereof is used as an emulsifier and emulsion polymerization is carried out using a polymerizable monomer or monomers having, within their molecule, a group reactive with a carboxyl group as raw materials for emulsion polymerization, whereby the resin produced by emulsion polymerization and the emulsifier react with each other efficiently on the occasion of film formation and form a crosslinked structure. When a compound having a polymerizable unsaturated group in addition to the carboxyl group and long-chain alkylthio group or a salt thereof is used as the emulsifier, not only the above-mentioned crosslinked structure is formed but also the polymerizable unsaturated group in the emulsifier will react with the unsaturated group in the polymerizable monomer or monomers in the manner of grafting. As a result, the compatibility between the emulsifier and the emulsion-polymerized resin is improved.
