    • When first and second ignition switches are turned from on to off, a first or second CPU determines whether an abnormality has occurred in an electronically controlled brake system. When the first or second CPU determines that an abnormality has occurred, the first and second CPUs immediately turn off first and second main relays, respectively. When both the first and second CPUs determine that operation is normal and an occupant detection switch is off, the first and second CPUs keep the first and second main relays on for a predetermined period of time as a self-maintaining process during normal operation. In this self-maintaining process during normal operation, the period during which the first and second main relays are kept on is changed according to the voltage of a vehicle battery.
    • 当第一和第二点火开关从接通转为断开时,第一或第二CPU确定电子制动系统中是否发生异常。 当第一或第二CPU确定发生异常时,第一和第二CPU分别立即关闭第一和第二主继​​电器。 当第一和第二CPU都确定操作正常并且乘员检测开关关闭时,第一和第二CPU在正常操作期间将第一和第二主继​​电器保持预定时间段作为自维持处理。 在正常运行时的这种自维持处理中,保持第一和第二主继​​电器的期间根据车辆电池的电压而变化。

    • One of the objects of the invention is to provide an optical disc apparatus capable of focusing on a signal surface regardless of appearance of a fake signal. The optical disc apparatus includes: an optical pickup for outputting a signal on the basis of reflection light of the optical disc, the optical pickup including an objective lens; a driving section for moving the objective lens of the optical pickup relative to an optical disc surface; and a focus controlling section for carrying out a focus detecting operation by detecting a reflection signal on a signal surface of the optical disc from the output signal of the optical pickup within a predetermined range of distance between the objective lens and the optical disc surface while the objective lens is being moved relative to the optical disc surface by means of the driving section.

    • A bottom hold circuit generates a bottom hold signal (BH signal) from an RFDC signal from an RF amplifier, and sends it to a comparator. The comparator compares a reference level and the BH signal, and generates an Rfdet signal having H level if the BH signal was found to be lower than the reference level. The Rfdet signal is a signal having H level when a laser spot falls in a data-recorded area on an optical disk, and having L level when in a non-recorded area. When it was detected that Rfdet signal had H level throughout a single turn of the disk, a servo-processing microcomputer controls an optical pickup so as to apply tracking servo. This makes it possible to precisely detect a boundary position between the data-recorded area and non-recorded area. If the optical disk is decentered, the boundary area corresponded to the amount of decentering can successfully be isolated from the data-recorded area.
    • 底部保持电路从RF放大器的RFDC信号产生底部保持信号(BH信号),并将其发送到比较器。 比较器比较参考电平和BH信号,并且如果发现BH信号低于参考电平,则产生具有H电平的Rfdet信号。 当激光光斑落在光盘上的数据记录区域中时,Rfdet信号是具有H电平的信号,并且在非记录区域中具有L电平。 当在盘的一圈中检测到Rfdet信号具有H电平时,伺服处理微计算机控制光学拾取器以便施加跟踪伺服。 这使得可以精确地检测数据记录区域和非记录区域之间的边界位置。 如果光盘偏心,则对应于偏心量的边界区域可以成功地从数据记录区域隔离。
