Abstract: PROBLEM TO BE SOLVED: To accurately control output voltages before and after stopping the drive of inductive loads in motors, or the like in power supplies including a first output line for output of a first voltage to the inductive loads and a second output line for output of a second voltage lower than the first voltage.SOLUTION: When a voltage of the first output line 33 increases and exceeds a voltage of a reference voltage 42, a light emitting diode 16 lights up, and a photocoupler 18 performs feedback control in a direction where a control circuit 15 steps down a secondary-side voltage of a transformer 20.

Abstract: <P>PROBLEM TO BE SOLVED: To eliminate disadvantages when a management table is curtailed.  <P>SOLUTION: In response to a notice that an HDD 38 is mounted, a CPU 28 reads a meta-information table TBL1 and a pointer information table TBL2 recorded on the HDD 38, which can be attached and detached freely, into a DRAM 30. At this time, meta-information described in the meta-information table TBL1 represents the attributes of content recorded in the HDD 38. A pointer described in the pointer information table TBL2 comprises a pointer value pointing to the meta-information described in the meta-information table and a pointer identification number. The CPU 28 extracts from the pointer information table TBL2 a pointer different from a fixed relation in the corresponding relation between the pointer value and the pointer identification number, and corrects the pointer value of the extracted pointer so as to establish the fixed relation. The CPU 28 corrects the layout of the meta-information described in the meta-information table in association with the correction of the pointer value. A load onto the video recording process of the content is reduced.  <P>COPYRIGHT: (C)2011,JPO&INPIT
