The present invention provides a charged particle beam irradiating apparatus capable of simply preventing unevenness or reduction in a peripheral portion of the dose distribution of a charged particle beam. A charged particle beam irradiating apparatus includes scanning electromagnets that scan a charged particle beam and a control device that controls the operations of the scanning electromagnets. In the charged particle beam irradiating apparatus, the control unit changes a scanning speed when the charged particle beam is irradiated along an irradiation line such that a peripheral portion of the dose distribution of the charged particle beam is corrected.

A control device for controlling mold oscillation in a continuous casting machine comprises a horizontal position detector, an open-close control device and hydraulic cylinders. The horizontal position detector is attached to a piston rod of the hydraulic cylinder for detecting an actual position of long-side copper plates of a mold. The open-close control device further comprises a reference position compensation circuit where a predetermined offset value is received. The reference position compensation circuit produces a compensation signal with which a target position of the long-side copper plates is modified. The open-close control device controls the hydraulic cylinders according to the compensation signal such that a deviation between the actual horizontal position and the target horizontal position of the long-side copper plates becomes equal to the offset value.
