A method of the present invention is used to control a flying height of a head operable to read data from and write data to a disk of a recording medium housed in an enclosure. In this method, the head is positioned to a predetermined radial measurement location on the disk to obtain error information on errors in the positioning of the head. A frequency analysis is performed on the obtained error information. Disturbance information on errors caused by a wind disturbance is calculated from the frequency analysis result. Pressure information on an air pressure in the enclosure is calculated based on the calculated disturbance information. A control value for controlling a flying height of the head with respect to the disk is determined based on the calculated pressure information. The flying height of the head is controlled based on the determined control value.

A mechanism for osteosynthesis 1 is provided that is capable of finely adjusting the amount of movement of a fractured bone, quantifying the amount of the movement and can be used both in pulling the fractured bones apart from each other and pulling the fractured bones nearer toward each other. A first mechanism for osteosynthesis 1 of the present invention comprises a plate part 2 for reducing two or more fractured bones monolithically by fixing at least both ends of the plate part 2 on the fractured bones and a sliding part 25 for moving one fractured bone along a sliding elongate hole 3 formed in the plate part 2 so as to elongate from the one fractured bone toward another fractured bone, the sliding part 25 comprising a rack 31 formed on an inner surface of the sliding elongate hole so as to extend along a sliding direction and a pin inserted in the sliding elongate hole 3, the pin 4 having a head portion 41 having a pinion for engaging with the rack 31 and a base portion 45 to be inserted into the one fractured bone, wherein the sliding part 25 moves the one fractured bone slidably along the sliding elongate hole 3 by rotating the pin 4.

An optical disk apparatus includes a carriage actuator that drives the carriage with a two-phase stepping motor. The carriage is provided with an objective lens that condenses a laser beam onto an optical disk and a lens actuator that moves the objective lens. A system controller drives the two-phase stepping motor in a first conduction mode of supplying current only to A-phase exciting coil and a second conduction mode of supplying current only to B-phase exciting coil in one-phase excitation drive mode, and detects a travel distance of the carriage based on a relative displacement of the objective lens with respect to the carriage, thus to control the current conduction to the A-phase exciting coil and the B-phase exciting coil based on the detection result, such that the travel distance of the carriage in the first and the second conduction mode becomes substantially the same.

A container commonly usable for electromagnetic cooking heaters and microwave ovens. A resin container commonly usable for electromagnetic cooking heaters and microwave ovens having an aluminum thin, film on the bottom thereof for storing food therein. The aluminum thin film is 5–30 μm in thickness and 70 cm2 in area, and has no projections having a curvature radius of less than 2 cm over the entire surface thereof. The aluminum thin film covers 30–80% of the bottom area of the container.

A storage apparatus rotates an optical recording medium at two or more kinds of rotational speeds. The rotational speed is decreased when a read or write margin becomes less than or equal to a first predetermined value or, when a frequency of generation of a servo abnormality of a tracking servo and/or a focus servo is greater than or equal to a first predetermined frequency. On the other hand, the rotational speed is increased when the read or write margin becomes greater than or equal to a second predetermined value or, when the frequency of generation of the servo abnormality of the tracking servo and/or the focus servo is less than or equal to a second predetermined frequency.

A position sensor detects a position of an objective lens for irradiating light onto an optical disk. An output adjustment of the position sensor is used for correcting characteristics change due the change with the passage of time. The position of an objective lens and the output of a position sensor are measured at a reference time, the ratio at the neutral point is determined in advance, and when the device is used, the position of the objective lens and the output of the position sensor are measured. The output level at the neutral point during using the device is calculated from the measurement result and the ratio at the neutral point.
