摘要： A micro movable mechanism system includes a micro movable mechanism. A target position generating section generates a signal indicative a target position of the micro movable mechanism. A nonlinear control unit outputs a controller output signal indicating a control value based on a difference between the target position signal and a signal indicating a current position of the micro movable mechanism. A root correction section drives the micro movable mechanism based on a signal proportional to a square root of the control value.

摘要： A projector that can solve a problem in which a projection image is disturbed due to deviation of incident positions of projection light to a screen is provided. Projection section 11 includes LD light emission section 111 and scanning section 112 that scans light emitted by LD light emission section 111 and projects the scanned light to the rear plane side of the screen. Control section 12 controls an amount of light emission of the light and a scanning angle of scanning section 112 based on an image signal so as to cause projection section 11 to project an image corresponding to the image signal to the screen. Control section 12 corrects an orientation of projection light corresponding to each pixel of the image projected from projection section 11 based on a refractive index of the light transmission member and a scanning angle of scanning section 112 so as to correct an incident position of the projection light on the screen.

The micro tracking actuator further has a magnet arrangement held to another of the carriage and the supporting spring to face the coil means in a predetermined direction. The magnet arrangement traverses the magnetic flux to have a particular size which varies in accordance with a predetermined relation in response to a relative movement between the coils and the magnet arrangement. The carriage is movably mounted to a magnetic disk device to which the head positioning mechanism applied. The supporting spring is attached to the carriage and rotatable around a predetermined axis extending in the predetermined direction.
