    摘要: A method of plating for filling via holes, in which each via hole is formed in an insulation layer covering a substrate so as to expose, at its bottom, part of a conductor layer located on the substrate. A copper film is formed on the top surface of the insulation layer covering the substrate, and the side walls and bottoms of the respective via holes. A strike plating of copper is provided on the copper film, and the substrate is immersed in an aqueous solution containing a plating promoter to thereby deposit the plating promoter on the surface of the copper strike. The plating promoter is removed from the copper strike plating located on the top surface insulation layer while leaving the plating promoter on the side walls and bottoms of the respective via holes. The substrate is subsequently electroplated with copper to fill the via holes.

    摘要: A drive torque of a vehicle drive wheel is controlled so that a slip ratio between the drive wheel and a road surface is equal to a target value. A determining function of which the sign varies when the slip ratio is equal to the target value, and a switching function comprising a time integral of the determining function, are set, and the drive torque target value is set such that it is directly proportional to the switching function. Alternatively, the drive torque target value is set based on the switching function which is set equal to the determining function and corrected based on an angular acceleration of the drive wheel.

    摘要: In an apparatus for controlling the braking force applied to the wheels of a vehicle, the braking force required for the vehicle is calculated according to a brake pedal depression amount and the weight of the vehicle. This braking force is allocated to the wheels, according to static loads acting on the wheels which vary according to the vehicle loading conditions. Alternatively, the forward/backward acceleration of the vehicle and sideway acceleration of the front and rear axles are detected, dynamic loads acting on the wheels are calculated from the static loads and these accelerations, and the braking force is allocated according to these dynamic loads. Preferably, the roll angles of the front and rear axles are respectively detected, and the detected sideways accelerations are corrected based on these angles. By way this braking force control, braking force can be optimized according to the loading conditions in commercial vehicles, such as trucks, where wheel load conditions largely vary.
