There is also provided a disc reproducing apparatus for reproducing digital data by an optical unit in which playback data are obtained by reproducing record data recorded on a disc-shaped recording medium in such a manner that a cluster-linking sector longer than an interleaving length is provided in a linking section of each cluster composed of a predetermined number of sectors, the resulting data is interleaved and recorded on the disc-shaped recording medium, and the playback data are deinterleaved and freed or the cluster-linking sectors so as to be stored transiently in a storage unit.

In this manner, data may be read out continuously from the storage unit at a predetermined rate without interrupting the reproducing operation at the cluster-linking sector of the data recorded on the medium.

摘要： A power-supply control device includes a power-supply-state transition control section, body-capable-of-movement detection sections, and an instruction section. The power-supply-state transition control section shifts a state of an operation target section from one state to another state among power-supply states and a non-power-supply state. The body-capable-of-movement detection sections detect a body capable of movement in a region. The instruction section provides, on the basis of results of detection of the body capable of movement by the body-capable-of-movement detection sections, at least an instruction for shifting between one of the power-supply states and the non-power-supply state, among instructions for shifting the state of the operation target section from one state to another state with the power-supply-state transition control section.

摘要： Unwanted electromagnetic waves are eliminated in a frequency output circuit comprising an open-collector output terminal whereby radio noise can be reduced. A frequency output circuit 10 comprises an open-collector transistor Q4 with an open-collector output terminal connected to a pull-up resistor Rf connected to an external power supply Vex. A current limiting circuit 16 limits a current through the output terminal such that a high potential and a low potential of the output waveform of a frequency signal outputted by an output circuit 12 are smoothly switched. The current limiting circuit 16 is formed by a differential pair circuit of transistors Q1 and Q2 each with a resistor provided in the emitter thereof, and a current mirror circuit comprising an open-collector transistor, for example.
