摘要： A record medium of disc type is recorded by a constant linear velocity. The record medium is reproduced by a reproducing apparatus, which reads the information from the rotated record medium into a buffer memory by a transmission rate corresponding to the number of rotation of the record medium and outputs the read information from the buffer memory to an external apparatus by a predetermined output rate. The method of reproducing the record medium by the reproducing apparatus is provided with the steps of: setting radial ranges of a plurality of virtual zones on the record medium, each of which is in a ring shape, and the number of rotation for each of the virtual zones, on the basis of upper and lower limit values of the transmission rate, which are predetermined to be higher than the predetermined output rate, a radius of the most inner circumference of an area where the information is recorded on the record medium, and a memory capacity of the buffer memory; rotating the record medium by a constant angular velocity in each of the set virtual zones by the set number of rotation; and reading the information from the rotated record medium by the transmission rate corresponding to the set number of rotation in each of the set virtual zones.

摘要： A pick-up point dislocation detecting device for detecting dislocation of a pick-up point of pick-up means in a disc player. The pick-up point is dislocated from a recorded region of a recording disc being played back on the disc player. The dislocation detecting device compares the signal level of an electric signal obtained from the pick-up means with a reference level. The reference signal corresponds to the signal level of the electric signal when the pick-up point is located within an intervening region between two neighboring tracks on the recording disc. The dislocation detecting device produces a dislocation detection signal when the signal level of the obtained electric signal falls below the reference level.

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.
