摘要： An optical disk data recording and reproducing apparatus includes variable delay circuits in the recording and reproducing sections of the apparatus. The delay of the reproducing section delay circuit is adjusted when the error ratio determined for a reproduced data signal corresponding to a recorded data signal is greater than a predetermined value. When the error ratio is less than the predetermined value after adjustment of the delay circuit, the delay of the delay circuit in the recording section is adjusted to match the adjusted delay of the reproducing section delay circuit and the delay of the latter circuit is retured to its original value.

The servo circuit according to this invention comprises a first comparator for comparing RF signals from a pair wobbled pits on a optical disk and generating a difference signal indicating the level difference between the AF signals; a holding means for holding the difference signal for a predetermined period; a reference level producing circuit for setting reference levels having a predetermined width with the level of a previously sampled difference signal of the holding means as a center; a second comparator for comparing the level of a presently sampled difference signal of the first comparator with the reference level and outputting a first signal indicative of the comparative result; and a selector for selecting and outputting, as a tracking error signal, either the presently sampled difference signal and a second signal having a level within the predetermined width of the reference level in accordance with the comparative result. The presently sampled difference signal is selected when the level of the presently sampled difference signal is within the reference level and the second signal is related when the presently sampled difference signal is out of the reference level.

摘要： A recording-reproducing clock generator circuit generates a reproduced clock having a predetermined frequency from a read out signal including such pulses that the interval between two successive pulses thereof at a predetermined length is to be used as a synchronizing signal region. The circuit generates a reference clock of a predetermined frequency, generates a first sync signal detection signal when the distance between two successive pulses in the input signal measured by means of the clock pulses is equal to a predetermined reference value, separates a clock edge pulse from the input signal by using the first sync signal detection signal, and generates the reproduced clock having the predetermined frequency and synchronized with the separated clock edge pulse.

摘要： An electronic control unit is incorporated as one of a plurality of electronic controllers composing a system for controlling in-vehicle devices on a distributed and mutually-synchronized control manner in a vehicle. The plurality of electronic control units are communicably connected with each other via an in-vehicle network to communicate information including the time-dependent data among the electronic control units. Each electronic control unit comprises a control member, an elapsed-time calculation component, and a validity determination component. The control member performs the control on the basis of time-dependent data acquired in time series relating to the vehicle. The elapsed-time calculation component is configured to calculate an elapsed time elapsing from acquisition of the time-dependent data. The validity determination component is configured to use the calculated elapsed time to determine whether or not the time-dependent data is valid or not for the control in terms of freshness of the time-dependent data.

摘要： A self-position detecting unit detects a self-position. A time calculating unit calculates a time of a time zone where the self-position detected using the self-position detection unit exists. A time display unit displays the time calculated using the time calculating unit. A display control unit causes the time display unit to display time of the first time zone where the self-position exists continually in an area in a second time zone, which is adjacent to the first time zone, when determining that the self-position moves into the second time zone. The area has a predetermined width from a boundary between the first time zone and the second time zone. The display control unit further causes the time display unit to display time of the second time zone when determining that the self-position moves beyond the area.
