Abstract: The electromagnetic vibration suppression device includes a plurality of electromagnet pairs arranged in the width direction of a steel plate and which suppresses vibration of the steel plate running between electromagnets in each electromagnet pair using a control unit. The pseudo displacement calculation means calculates a pseudo displacement amount for the steel plate on the basis of the switching between ON and OFF of a sensor attached to the electromagnet pairs. The pseudo edge position calculation means calculates a pseudo edge position for the steel plate on the basis of the pseudo displacement amount. The current amount control means individually controls the amount of current that flows to the electromagnets on the basis of the pseudo edge position.

Abstract: An electromagnetic vibration suppression device 1 includes a plurality of electromagnet pairs 2 (2A, 2B) disposed in the width direction of a steel sheet Sa. Each electromagnet pair is oppositely disposed in the thickness direction of the steel sheet Sa traveling in a predetermined direction. A control section 4 is adapted to control current to be applied to each electromagnet 2A, 2B to suppress the vibration of the steel sheet Sa traveling between electromagnets 2A and 2B.

Abstract: An electromagnetic strip stabilizer includes: a pair of electromagnets, opposed to each other, that generate magnetic forces to act on a steel strip passing between the electromagnets after a surface coating process being applied to the steel strip; a pair of sensors, each sensor provided for each of the electromagnets, that detect a distance between a corresponding one of the electromagnets and the steel strip; and a control section configured to control a current supplied to each of the electromagnets and control a vibration of the steel strip at least based on the distance between the steel strip and each of the electromagnets detected by each of the sensors. The control section determines control gains used to control the current supplied to each of the electromagnets at least based on a thickness and a width of the steel strip.

Abstract: An information providing center calculates an estimated traveling time to elapse before a vehicle arrives at a destination by using traveling information transmitted from an on-vehicle system and determines contents information to be provided to the on-vehicle system in conformance to the calculated traveling time. The information providing center prepares a program list containing the contents information that has been selected, information indicating the order in which the contents information is to be played and media information indicating how the contents information is to be obtained and transmits the program list to the on-vehicle system. The on-vehicle system obtains and plays the contents information as indicated in the transmitted program list.
