Abstract: A four-wheel drive vehicle has a center differential (6) which transmits the output torque of a power plant (P) to both front (13,15) and rear wheels (19,22) in such a manner as to permit the front (13,15) and rear wheels (19,22) to rotate at different speeds. A differential control system has a differential rotation limit member which acts on the center differential (6) to limit differential rotation of the front and rear wheels to a degree which is increased as the difference in rotational speed between the front and rear wheels increases. The degree of limitation on the differential rotation of the front and rear wheels is changed according to a predetermined characteristics which nullifies the degree of limitation in a range where the difference in rotational speed is relatively small and provides a gain in a range where the difference in rotational speed is relatively large. The gain is changed according to a factor which governs the running condition of the vehicle.

Abstract: An electron-wave coupled semiconductor device 10, in particular a semiconductor switching device, comprises a first layer 14 of semiconducting material having a first bandgap, and a second layer 16 of material formed on said first semiconducting layer 14 and having a second bandgap greater than the first said bandgap. First and second electron waveguides 34,36 are formed alongside but spaced apart from each other in the first semiconducting layer 14 adjacent the boundary between this layer and said second layer 16. A gate region 32 extends over said second layer 16 transverse to and over said electron waveguides 34,36. First contact means E1,E3 provides input connections to said first and second electron waveguides 34,36 on one side of said gate region 32 and further contact means E2,E4 provides separate output connections from said first and second electron waveguides 34,36 on the opposite side of the gate region 32 from said first contact means E1,E3. The dimension of the electron waveguides 34,36 under said gate region 32, both along and transverse to said electron waveguides 34,36, and also the dimension between said electron waveguides 34,36 are smaller than the elastic mean free path for electrons at the operating temperature of the device 10. A signal applied to the gate region 32 can be used to switch a signal applied to said input contact means E1,E3 selectively to a selected one of the output connections E2,E4.

Abstract: The invention relates to a brake lining wear warning apparatus and a method for making it. The object is to specify a simple method for making a multistage brake lining wear warning apparatus which is distinguished by such small production tolerances that the warning points lie in acceptable tolerance bands. In principle, a two-stage method is proposed as the solution, in which an insertion part (44) is made first, preferably by injection moulding, and is provided with an electrical conductor (17). The unit, consisting of the insertion part (44) and electrical conductor (17), is subsequently encased, preferably by extrusion-coating. In one preferred embodiment, a two-stage brake lining wear warning apparatus has two electrical conductors (17) in loops with a different extent. The conductors are each provided with an electrical resistor (42, 43) so that, in conjunction with an electrical circuit, cable connections between the brake and warning indicator are saved. <IMAGE>
