摘要： An emergency report device comprises: a power supply control unit that switches an electric power source from a main battery to an auxiliary battery when a supply voltage of the main battery is smaller than a predetermined threshold value; and an auxiliary battery operational check unit that performs an operational check of the auxiliary battery if the operational check of the auxiliary battery is being performed at a time when the vehicle drive mechanism starts, and if the operational check of the auxiliary battery is being performed for a first time during a period between an end of a previous day and a present time. The operational checking of the auxiliary battery is based on a current input into the auxiliary battery operational check unit from the auxiliary battery.

摘要： An onboard wireless communication system includes a power supply circuit, a wireless communication circuit, a control circuit, and a current integration circuit. The current integration circuit calculates an integration value of current fed from a battery after the battery starts discharging. The current integration circuit temporarily stops the calculation until transmission of a burglar alarm signal is completed when a burglar detection signal is outputted from a burglar detection ECU while the integration value is still smaller than a reference value. As a result, power supply from the power supply circuit to the wireless communication circuit is maintained. The power supply is stopped when the integration value is equal to or larger than the reference value while the burglar detection signal is still not outputted from the burglar detection ECU.

摘要： The present invention provides a construction that can obtain tracking error signals suitably from any of the optical disks having differing track pitch by reducing the main spot size in an optical recording disk apparatus which reads and retrieve information on an optical recording disk. In the optical recording apparatus, diffraction element 8 for 3-beam generation increases the rim intensity of zero-order beam by decreasing the intensity of the zero-order beam in inner diffraction region 81 to decrease the size of the main spot. Additionally, between optical recording disks of the DVD system and the CD system which retrieve and record information on the optical recording disk apparatus, the optical system is configured such that the sub-spot is centered at the location shifted from the center of the main spot in the tracking direction at a distance of 0.25 times the track pitch.
