Abstract: A method of controlling start-up of a sensorless spindle motor used in a disk apparatus reduces time spent on start-up of a spindle motor with high reliability. The motor is used for rotating a disk on which information is recorded, and no sensor is provided in the motor for sensing an angular position of a rotor relative to a stator of the motor. The motor is operated at a steady rotational speed and is stopped by supplying a stop command. An aligning operation is performed immediately after the motor is stopped. The aligning operation is performed to rotate the rotor to a predetermined angular position relative to the stator of said motor. The motor is operated at a steady speed by a synchronization control when operation of the motor is started by supplying a start command.

Abstract: A method in which a surface layer material whose amount of reduction is to be measured is activated to find a distribution ratio of two or more kinds of radioactive nuclides that are produced in the space in the surface layer of the material, and the distribution ratio is used as an index for the amount of reduction of surface layer material. The amount of reduction in the surface layer material is measured in situ, nondestructively, easily and irrespectively of obstacles and the distance that exist between the detector and the material that is to be measured.
