C.,wherein the combined weights of components (B) and (C) is from about 1 wt. % to about 49 wt. %, and the weight ratio of (B)/(C) is from about 1/99 to about 99/1. The resin composition is particularly suitable for bonding a polypropylene resin layer and an ethylene/vinyl alcohol copolymer layer, and a polypropylene resin layer and a nylon layer.

    摘要: The steering operation of a motor vehicle with steerable front and rear road wheels is controlled by steering the rear road wheels with an actuator such as an electric motor which produces a steering force dependent on a deviation of the actual rear wheel steering angle from a target rear wheel steering angle. The rear road wheels are thus controlled with a characteristic dependent on the coefficient of friction of a road on which the motor vehicle travels and the steering speed at which the motor vehicle is steered. Typically, a steering control method comprises the steps of detecting the steering angle of the front road wheels, determining a target steering angle for the rear wheels based on the steering angle of the front road wheels, detecting the actual steering angle of the rear road wheels, calculating a steering angle deviation of the actual rear wheel steering angle from the target steering angle, determining a rear wheel steering force based on the steering angle deviation, and steering the rear road wheels to the target steering angle with the determined rear wheel steering force.

    摘要: Disclosed herein is a preparation process for polypropylene-base resin compositions, which process comprises heating at a temperature of 170.degree.-280.degree. C. a mixture containing a crystalline ethylenepropylene block copolymer having a specific composition, an ethylene-propylene copolymer rubber having a specific composition and viscosity, an inorganic filler having a specific particle size, and an organic peroxide, all in specified amounts. The thus-obtained polypropylene-base resin compositions are suitable for use in the production of large moldings such as automobile bumpers, fenders and body sidemembers because of their excellent low-temperature impact resistance, high molding fluidity, good paintability and high stiffness as well as their low preparation cost.
