摘要： An optical recording/reproducing apparatus is intended for a recording medium having at least two information recording layers. The apparatus has at least two lenses, a first lens and a second lens, for condensing a light beam to irradiate an information recording layer. The at least two lenses are designed such that a light beam condensed by these lenses upon an information recording layer closest to these lenses has a minimum spherical aberration.

摘要： A drive control apparatus and method drives an AC motor by applying a rectangular wave voltage thereto. The apparatus estimates the torque of a rotor of the AC motor, and detects a torque deviation which is the difference between the estimated torque and a required torque of the motor. A controller controls a state of the rectangular wave voltage applied to the AC motor, through torque feedback control based on the torque deviation, so that the torque approaches the torque command value. The controller detects a current rotation speed of the motor, and switches, in a predetermined order, a plurality of predetermined rectangular wave voltage states corresponding to different phase values of the rectangular wave voltage. The switching timing of the rectangular wave voltage states is set to a timing that deviates from a reference timing determined based on the current rotation speed, by a length of time corresponding to the torque deviation.

摘要： In an optical pickup device, an objective lens unit includes a first lens, a second lens for converging a light beam which passed through the first lens on an information recording layer of a recording medium, and a second-lens-driving-use actuator for adjusting the distance between the first and second lenses. The second lens has a reflecting section for reflecting an outer part of the light beam which passed through the first lens and reached the second lens. Moreover, the optical pickup device includes a condenser lens, a cylindrical lens and a light receiving element for detecting a reflected light beam reflected by the reflecting section, and a control device for detecting the distance between the first and second lenses according to the result of detection and for controlling the second-lens-driving-use actuator according to the result of detection. With this structure, the occurrence of spherical aberration due to an error in the thickness of a cover glass of the recording medium and variations in the thickness of the objective lens is limited.

摘要： The object of the present invention is to carry out control and enable an engine to output a desired power, thereby preventing unexpected charge or discharge of storage battery means. A power output apparatus of the present invention sets energy Pe to be output from an engine, in order to cancel a deviation .DELTA.Pb of a charge-discharge electric power Pb of a battery from its target value Pb* , and controls operation of the engine to output the energy Pe. The energy Pe output from the engine is subjected to torque conversion by means of a clutch motor and an assist motor and output to a drive shaft as a required power. In case that the converted energy is not equal to the required power, the battery is charged with the surplus electric power or is discharged to supplement the shortage of electric power. Namely regulation of the energy Pe results in controlling the charge-discharge electric power Pb of the battery. When the target value Pb* is set equal to zero, the power output apparatus enables a desired power to be output to the drive shaft without causing unexpected charge or discharge of the battery.
