Abstract: Provided is a transferring and molding method capable of forming a molded article on which a pattern is transferred in a prescribed position by automatically correcting a shift when there is produced a molded article on which the pattern is transferred with a shift. When the pattern of a molded article has a shift, the shift dimension and the shift direction of the pattern of the molded article are detected as digital values, and positional correction is carried out by automatically moving the transfer film by the detected shift dimension toward the side opposite from the detected shift direction. Thereafter, the pattern is transferred in the prescribed position of the molded article that has undergone the transferring, and molding is carried out.

Abstract: A vibration test system for structures comprises a vibration exciter that vibrates a real model portion, a load meter that measures a load, and a computer that receives a numerical model representing a numerical model portion. The computer includes a block that calculates a displacement, which is made in a predetermined time after completion of measurement, according to a load value and an external force value. A signal production block produces a command signal using as a target value the displacement calculated by the displacement calculation block. A step control block controls the displacement calculation block and signal production block so that they will act cyclically. The displacement calculation block uses an ?OS method to time integrate a solution of a vibrational equation.
