  • Patent number: 8075836
    Abstract: Steel-sheet continuous annealing equipment includes, in sequence, a pre-heating zone, a heating zone, a soaking zone, a cooling zone, a reheating zone, an overaging zone, and a final cooling zone, and further includes a rapid heating region and a rapid cooling region that are provided within a range from the reheating zone to the final cooling zone (including the reheating zone and the final cooling zone), the rapid heating region allowing rapid heating of a steel sheet at a heating rate of 15° C./s or more and the rapid cooling region allowing rapid cooling, at a cooling rate of 10° C./s or more, of the steel sheet that has been rapidly heated in the rapid heating region. Various steel-sheet products ranging from mild steel sheets to ultrahigh-tensile steel sheets can be produced by performing a heat treatment with such steel-sheet continuous annealing equipment.

  • Patent number: 7340330
    Abstract: The invention has an engine maximum torque calculating processor for calculating plural engine maximum torques showing a maximum value of engine torque, and an engine limit torque calculating processor for calculating a minimum value of the respective engine maximum torques as engine limit torque. Because the minimum value of the engine maximum torques is calculated as the engine limit torque, it is possible to reliably prevent the engine from entering an excessive rotating state. Further, because the engine limit torque is calculated on the basis of the minimum value of the engine maximum torques, the engine limit torque can be reliably calculated even when there is an individual difference in the engine, an electric generator, etc. and there are calculation errors further, for example, electric generator target torque and the electric generator maximum torque.

  • Patent number: 6968260
    Abstract: A vehicle drive control apparatus includes buffers, as a recording portion, set for each of a plurality of storage items, each of the plurality of storage items having a different sampling cycle, and a controller that samples variable quantities, that indicate a status of a vehicle that changes with a running of the vehicle, at a sampling cycle set for each of the plurality of storage items and records the variable quantities in each of the buffers as storage data.
