摘要： According to one embodiment, a frequency control apparatus includes an eccentric component storage module, a frequency correction amount calculating module, and an oscillator control module. The eccentric component storage module stores in advance an eccentric component calculated by a discrete Fourier transform of the number of clock signals measured for each servo frame. The frequency correction amount calculating module calculates the number of clock signals corresponding to the servo frame based on the eccentric component stored in the eccentric component storage module and calculates a frequency correction amount corresponding to the servo frame based on the number of clock signals. The oscillator control module controls the operation of a frequency oscillator such that a frequency for oscillating a clock signal in the frequency oscillator is adjusted according to the frequency correction amount calculated by the frequency correction amount calculating module.

摘要： The present invention provides an information storage apparatus that generates a tracking error signal based on a detection signal, and performs various control operations based on the tracking error signal. When the operation mode is a seek operation mode, the information storage apparatus generates a tracking error signal by holding the peak value of the detection signal. When the operation mode is a tracking operation mode, the information storage apparatus generates a tracking error signal directly from the detection signal. With this information storage apparatus, stable control operations can be performed, regardless of changes of conditions.

摘要： Metal side plates having projections are attached to fins at the ends of heat exchanger units, to thereby carry out heat exchange between cooling air flowing through spaces between the heat exchanger units, and the side plates. In comparison with a conventional radiator having no side plate, a heat exchanging area (heat radiating area) for the cooling air flowing through the spaces can be increased and, thus, a heat exchangeability (heat radiation capacity) can be enhanced in the present invention.

摘要： An ignition control apparatus for an internal combustion engine for preventing ignition control upon occurrence of rotation reversal of the engine includes a rotation sensor (3) disposed in opposition to projections (11, 12) of a rotor (1), and an ignition timing control circuit (4) for fetching a rotation sensor signal (R) as a reference angular position signal to output a driving signal (P) to the ignition circuit (6). A retarded ignition control means (46) of the control circuit (4) measures a period of a specific interval of the sensor signal (R) while generating a driving signal (P) in dependence on the specific interval period. An arithmetic means (46) of the retarded ignition control means (46) sets an expectation period for accepting a succeeding sensor signal on the basis of the specific interval period to validate only the signal inputted during the expectation period.

摘要： An offset measuring unit receives a servo error signal E1 in which a change in an offset caused by a change in an amount of reflection light directly appears and which does not pass through a filter, and measures an offset amount in the servo error signal which is caused by a change in the amount of reflection light. A correction amount calculating unit calculates a correction amount to cancel out the offset amount and outputs the correction amount to an offset correcting circuit for an offset generating period so as to perform correction.

摘要： An eccentricity amplitude of a medium in an eccentricity measuring unit and an eccentricity phase for a start position of one rotation are measured. A region from the start position to end position of one rotation of the medium which was measured is divided into a plurality of regions every predetermined rotational angle, addresses are sequentially allocated to those regions, a sine value of a rotational angle which is increased every predetermined rotational angle has been stored in each address in an eccentricity memory. A read control unit forms an address (a) in an eccentricity memory corresponding to a rotating position of the medium where a light beam is irradiated at present while using the start position of one rotation of the medium as a reference and reads out a corresponding sine value sin&thgr;a from the eccentricity memory by the designation of the address (a). An eccentricity correcting unit obtains an eccentricity amount (L) on the basis of the sine value read out from the eccentricity memory and the measurement values measured by the eccentricity measuring unit, thereby controlling a VCM positioner so as to set off the eccentricity amount (L).
