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. The supporting spring holds the magnetic head to perform a seeking operation of the magnetic head in cooperation with the carriage.

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 includes a screen which has color stripes that are periodically arranged and that generate visible light corresponding to incident light. A laser light source section emits a light beam. A laser scanning section scans the light beam on a region of the color stripes arranged on the screen. A light detection section detects feedback light radiated from the screen corresponding to the light beam. A control section adjusts a light emission timing and a light emission period of the laser light source section based on a detection result of the light detection section and causes the laser light source section to emit the light beam such that light pulses enter the individual color stripes.

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.

摘要： A motor control apparatus that controls the rotational angle of a motor (111) which drives a rotating body (112) includes a synchronizing means (200) for generating and outputting an interrupt signal (700) based on an external reference signal (600) input from outside and a rotating body reference signal (500) generated by the rotating body, and a controlling means (300) for computing a command value for making the rotational angle of the motor follow a target rotational angle and outputting the command value to the motor each time the interrupt signal is inputted. The synchronizing means (200) changes the output period of the interrupt signal (700) in accordance with a time difference between the external reference signal (600) and the rotating body reference signal (500).
