Abstract: A speed ratio control system for a stepless variable speed transmission of vehicles having an electronic fuel injection control system. A speed ratio control signal for controlling the speed ratio of the stepless variable speed transmission is produced from the output fuel injection control signal from the electronic fuel injection control system and a target fuel injection quantity signal from an electronic arithmetic unit which generates the target fuel injection quantity signal in response to a throttle opening indication signal. The output fuel injection control signal is compared with the target fuel injection quantity signal to generate the speed ratio control signal which controls the speed ratio of the stepless variable speed transmission until the fuel injection indicated by the fuel injection from the electronic fuel injection system becomes equal to the target fuel injection quantity.

The error signal is supplied to throttle valve control means to shift a throttle valve into a position at which actual automobile speed equals the desired automobile speed. A superposed signal, consisting of the first electric signal and a negative feedback signal substantially indicating throttle valve position, is applied to a memory capacitor which provides the second electrical signal. Rememorization of the capacitor is controlled by a set switch through a memorization control circuit. The desired automobile speed level to be memorized on the capacitor is controlled by closure duration and closure repetition of the set switch.

Abstract: An antirattle spring for a disc brake is represented as being entirely disposed outside of a clearance between one of a plurality of edges of pad assemblies and a stationary member anchoring against the one edge. Consequently, the antirattle spring is freed from any restraint as would otherwise be imposed upon a designer of a more complicated and smaller sized configuration of the spring, and is therefore more likely to retain its resiliency than are prior art antirattle springs. The antirattle spring has one end thereof bolted to the stationary member and the other end thereof engaging one of the plurality of edges with a required elastic energy stored within the middle portion of the spring.
