摘要:
An optical disk drive of the present invention has a controller, which obtains saturation levels of a first reflected laser beam obtained by a laser beam with a playback light intensity and a second reflected laser beam obtained by a laser beam with a recording light intensity, in a signal processing circuit, based on the results of detecting the first and second reflected laser beams by a detector, computes the intensity of a recording laser beam output from a light source based on the saturation levels of the reflected laser beams specified by a signal processing means, and instructs a laser driving circuit to drive a laser driving signal capable of achieving the intensities of playback and recording laser beams based on the computation results.

摘要:
A base member is laid in a space portion, which is defined by an instrument panel, in a vehicle width direction over a generally entire width of the vehicle, and a plurality of ducts is integrally formed with the base member. Furthermore, a meter placing portion, on which a meter is placed, and an air bag placing portion, on which an air bas is placed, are formed on the base member, and a harness placing portion 26, on which a flat harness is placed, is also formed on the base member in the vehicle width direction. Accordingly, the base member with which the plurality of ducts is integrally formed is a separate body from the instrument panel. Even in the case where the size of the instrument panel is changed, the base member is not required to correspond to the instrument panel and, therefore, the ducts can be commonly used. Moreover, since the base member is formed with ducts each having a closed structure, in section, it has a predetermined physical strength. Since this base member is laid in the vehicle width direction over a generally entire width of the vehicle, that portion of the vehicle body where the instrument panel is arranged is increased in physical strength owing to the provision of this base member for the sake of a possible side crush or collision of the vehicle.
