Abstract: A safe driving behavior notification system includes: an obstacle detector to detect position of each obstacle existing around a subject vehicle; a first specifier to specify driving behavior to be carried out by a driver based on the detected position of each obstacle and information relating to the subject vehicle; a second specifier to specify driving behavior predicted to be carried out by the driver from the detected position of each obstacle and information on a travel state of the subject vehicle using a driving behavior model for the driver created based on past driving behavior of the driver; and a notificator to determine whether notification to the driver is necessary based on a degree of a difference between the driving behaviors specified by the first and second specifiers, and to notify the driver of information indicating action to be carried out when determining the notification is necessary.

Abstract: A method of water cooling a hot-rolled steel plate is disclosed. In this method, while a hot-rolled steel plate is being advanced lengthwise, a plurality of nozzles spray cooling water to the steel plate, and thus the plate is cooled to a predetermined temperature at a predetermined cooling rate. Before, while and after the plurality of nozzles carry out water-cooling, temperatures are consistently measured at predetermined temperature measurement points in cross-sectional areas of temperature measurement positions which are arranged lengthwise at predetermined locations of the steel plate. Each time such measurement is performed, degree of deformation of the plate is calculated on the basis of temperature differences between the temperature measurement points. When the calculated degree of deformation is not within an allowable range, corrections are made on the distribution of the water supplied by the plurality of nozzles.
