    摘要: In a multi-axle drive vehicle having a first axle which is directly coupled to a power source, and a second axle which is coupled to the power source by way of a coupling such as a viscous coupling which is adapted to transmit torque as a mathematical function of a difference in rotational speed between its input end and output end, to the end of eliminating the problems arising from transmission of braking force between the wheels of difference axles, the vehicle is further provided with a clutch for selectively interrupting transmission of power from the power source to the second axle, a brake sensor for detecting activation of a brake system of the vehicle, and a control unit for activating the clutch when the brake sensor has detected activation of the brake system. The conditions for activating the clutch may further include that the vehicle is running at a high speed which may be detected either directly or from a shift position of the power transmission system of the vehicle.

    摘要: The present invention relates to a method for cooling a steel strip in a continuous-annealing furnace. Conventionally, the steel strip is cooled by a water medium and, thus, oxidation is inevitable. Recently developed roll cooling methods can prevent oxidation but are disadvantageous in that the steel strip (1) is nonuniformly cooled as seen in its short width direction.The present invention attains uniform cooling by means of feedback-feedforward control, in which the blowing width of the gas-jet cooler (21, 53) is controlled by detecting the sheet temperature distribution with thermometers (24, 55, 60).
