摘要:
In a method for continuously casting an extremely low carbon steel using a continuous casting machine, by adjusting the chemical components of extremely low carbon steel within a specified range by taking into account an interface tension gradient in a concentration boundary layer on a front surface of a solidified shell, and also by optimizing intensities of the DC magnetic fields applied to the upper magnetic poles and the lower magnetic poles respectively corresponding to a slab width of a slab to be casted and a casting speed, it is possible to acquire the slab having high quality not only with the small number of defects caused by the entrainment of bubbles, non-metallic inclusion and a mold flux into the molten steel.

An apparatus and method for measuring a temperature of a high temperature liquid contained in a furnace. An optical fiber covered with a metallic tube is inserted through a passageway inside a nozzle arranged on a furnace wall of the furnace. The nozzle communicates with an interior of the furnace containing the liquid, and gas is supplied into the passageway inside the nozzle to prevent the nozzle from clogging. The metal-covered optical fiber is fed through the passageway inside the nozzle into the liquid such that spectral light radiated from the liquid enters a tip of the metal-covered optical fiber and is propagated therealong. The temperature of the liquid is determined by a radiation thermometer, coupled to the metal-covered optical fiber, based on the spectral light propagated along the metal-covered optical fiber.

In a four wheel steering system, the rear wheel turning mechanism is connected to the front wheel turning mechanism by way of a rear wheel turning angle ratio changing mechanism which is mechanically connected to both the front wheel turning mechanism and the rear wheel turning mechanism and transmits the mechanical displacement input thereinto from the front wheel turning mechanism to the rear wheel turning mechanism to drive the same by an amount the ratio of which to the amount of mechanical displacement input into the rear wheel turning angle ratio changing mechanism gives a predetermined rear wheel turning angle ratio. The rear wheel turning angle ratio changing mechanism is controlled in such a way that, when the front wheels are turned from the neutral position in a middle vehicle speed range, makes the rear wheel turning angle ratio negative for a moment immediately after initiation of turning of the front wheels and thereafter turns the same positive.

A front drive vehicle is provided with a four-wheel steering system and a traction control system. A control system for the vehicle detects whether a failure occurs in the traction control system, and causes the rear wheel turning mechanism to turn the rear wheels according to corrected rear wheel turning characteristics when it is determined that a failure occurs in the traction control system. The corrected rear wheel turning characteristics are shifted toward the reverse phase side with respect to the original rear wheel turning characteristics.

An automatic speed control system has a device for detecting an actual speed of vehicle, a device for setting a target speed of the vehicle, and a device for controlling the actual speed so that it approaches the target speed by adjusting a throttle opening. The improved system includes a down-shift device for making a down-shift operation of a transmission so as to accomplish the target speed under a predetermined condition when the vehicle runs on an uphill rod, and uphill end judge device for holding that an end of the uphill road has been reached when the throttle opening is reduced beyond a predetermined value from a maximum value after the down-shift operation. An uphill end of a short length can be properly detected so that a desirable speed control can be accomplished.
