摘要： PROBLEM TO BE SOLVED: To enable a user to enjoy the intrinsic high performance and high sound quality of a DVD audio reproducing apparatus etc., even under such increasingly severer working environment as that within an automobile. SOLUTION: The system is so arranged as to perform reproducing or recording for digital media or tuning by a PLL system on the basis of the frequency formed based on the time pulses included in GPS radio waves. The formation of the reference frequency is performed based on the frequency converted signal obtained by subjecting the signal of the time pulses included in the GPS radio waves to frequency conversion by using a PLL circuit. A phase comparator 23, a loop filter 24, a digital-to-analog converter 25a, a voltage control oscillator 25b, etc., constituting the PLL circuit are commonly used for a car navigation system.

摘要： PROBLEM TO BE SOLVED: To make a singer so as to start to singing smoothly in a karaoke (recorded accompaniment) device for DVD(digital versatile disk). SOLUTION: The text of a karaoke music is displayed on a display by captions and the present place of the text as a place to be sung at present is shown by the fringing of charactres or the classification by coloring of a sung part and a non-sung part. A time when the fringing of the characters or the classification by coloring of the sung part and the non-sung part appears at first is previously detected as a singing starting time and when the reproducing of the karaoke music advances to a time being a prescribed time before the singing stating time, a time being the prescribed time brfore the singing starting time, is displayed on the display to be informed to the singer.

摘要： PROBLEM TO BE SOLVED: To meet various working conditions with only one unit by making the best use of the heat loss tolerance capability of the unit owns. SOLUTION: High voltage and low voltage are switched and outputted by a transformer circuit 2A, and rectified and smoothed by a rectification and smoothing circuit 10, which are then inputted into a DC stabilization power circuit 20. The DC stabilization power circuit 20 generates stabilization DC voltage whose voltage value is changeable from the input of the rectification and smoothing circuit 10 for outputting. In the power circuit 20, the upper limit of an output variable range is switched to either of two of high and low stages, interlocking with high/low switching of the output voltage of the transformer circuit 2A. On the output side of the power circuit 20, an overcurrent protective circuit 30A is provided, which prevents the load current of a reference value or higher from flowing. When the output of the transformer circuit 2A and the upper limit of the output variable range of the power circuit 20 are changed to high voltage side, the reference value of the overcurrent protective circuit 30A is interlocked to small current side, and when it is switched to low voltage side, it is interlocked large current side.

摘要： PROBLEM TO BE SOLVED: To provide a DC stabilized power supply apparatus capable of maintaining constant output voltages by connecting in series a plurality of active elements passing load currents between an input terminal and an output terminal of the apparatus to distribute occurrences of heat due to the load currents, and even though an input voltage to the apparatus becomes smaller. SOLUTION: The apparatus comprises a step-down means 1 for stepping down an input DC voltage V1 to a DC voltage V2 via an emitter/collector path or a source/drain path, a series type regulator 2 for stepping down the DC voltage V2 to a predetermined DC voltage V0 via the paths, and a comparison circuit 3 for determining whether the DC voltage V1 is not higher than a predetermined reference value Vref. When the DC voltage V1 is not higher than the reference value Vref, the voltage between an emitter and a collector or between a source and a drain is controlled to become a saturated voltage for making a voltage loss by the step-down means 1 become negligible amount.

摘要： PROBLEM TO BE SOLVED: To provide an introduction synchronization device for a karaoke device to synchronize a start of a word part in an accompaniment with a start of singing of a singer to make the singer song comfortably and to eliminate making listeners of the singer uncomfortable when the singer fails to synchronize his song with the accompaniment. SOLUTION: A disk 1 is provided with a spindle motor 2 and an optical pickup 3. A control part 5 controls the spindle motor 2 and the optical pickup 3 to provide a signal processing part 4 with a signal read out. The signal processing part 4 produces a background video signal (a), a caption video signal (b), and an accompaniment aural signal (c). A start-of-singing detecting part 12 detecting a start of singing of a singer with a microphone 9 is provided. When the start-of-singing detecting part 12 detects a start of singing after an accompaniment starts, the accompaniment is controlled to start with a point of the accompaniment corresponding to a start of word in the accompaniment already detected by a cell type detecting part 10 regardless of the current position of the accompaniment.

摘要： PROBLEM TO BE SOLVED: To improve the reproduction efficiency of KARAOKE sing-along music with a KARAOKE sing-along machine for DVDs by detecting whether a reproduction portion is a non-singing-in part or singing-in part or not from the reproduction data of the KARAOKE sing-along music and reproducing the reproduction portion of the singing-in part while suitably skipping the reproduction portion of the non-singing-in part. SOLUTION: A DVD mechanism unit 16 of the KARAOKE sing-along machine 15 is set with a DVD 10, executes the processing relating to the DVD 10, such as reproduction and stop of the DVD 10 by the control signal from a control section 17 and reads out the data from the DVD 10 at the time of reproduction. A non-singing-in part/singing-in part detecting section 21 detects the non-singing- in part by the subtitle picture data from a signal processing section 18 and sends the results of the detection to the control section 17. The control section 17 suitably executes the skipping, such as fast feeding, relating to the DVD 10 in the DVD mechanism unit 16 when the results of the detection of the non- singing-in part comes thereto from the non-singing-in part/singing-in part detecting section 21.
