Abstract: PROBLEM TO BE SOLVED: To perform highly efficient encoding by the code book of a small size and to improve transmission efficiency in the case of orthogonally transforming acoustic signals (PCM signals) by MDCT and transmitting data by a vector quantization system. SOLUTION: An MDCT coefficient X(n) obtained in an MDCT device 1 is separated into an amplitude component a(m) and a phase component θ (m) in an amplitude/phase comparator 2, vectorized in a band division/vectorization device 3, then converted into index data IDa and IDb relating to amplitude and a phase by respective vector quantizers 7 and 8 by using the code books 5 and 6 provided for respective component data and transmitted.  Since separation into the respective components of the amplitude and the phase is performed, the transformation dimensional number of vectorization is made smaller on the side of the phase component θ (m) of the small deviation of statistic distribution than the side of the amplitude component a (m) of the large deviation, the highly efficient encoding is realized by valid bit distribution suited to the property of the acoustic signals and the data amount of the entire code book is reduced.

Filed: 1996-11-13
Abstract: PROBLEM TO BE SOLVED: To improve the drooping characteristic of the output current at operation for protection from overcurrent, and reduce short circuit currents, in a chopper regulator which has a circuit for protection from overcurrent. SOLUTION: An overcurrent detecting circuit 38 checks the continuity of an output transistor 31 by directing a flip flop 39 in case the voltage VR across a resistor 37 for overcurrent detection provided in series to an output transistor 31 is over the detection level during non-short circuit. Hereby, the output current IO is limited, and each member constituting a constant voltage power circuit 1 is protected from overcurrent caused by the ripple, etc., of load 6. On the other hand, a comparator 40 directs an oscillator 34 when it detects the short circuit of a load terminal O, based on feedback voltage VADJ, and lowers the switching frequency of the constant voltage power circuit 1. Furthermore, for an overcurrent detecting circuit 38, the detection level in detecting the overcurrent is set lower than that at non-short circuit, according to the direction of the comparator 40.

Title: Optical disk device
Inventor: OHATA HIROYUKI
IPC: G11B19/02
Filed: 1999-10-25
Abstract: PROBLEM TO BE SOLVED: To specify an address and a groove portion/inter-groove portion by reading a first address from the identification information section of a first sector and a second address from the identification information section of a second sector, and determining whether a track being scanned is a groove portion or an inter-groove portion according to the result of size comparison between the two addresses. SOLUTION: When a groove portion/inter-groove portion signal indicates a groove portion, a selection unit 5 outputs PID1, PID2, PID3+N and PID4+N, and outputs PID1+N, PID2+N, PID3 and PID4 when the groove portion/inter- groove portion signal indicates an inter-groove portion. These four values are all coincident with one another as long as the PID information of a disk is correctly read. Thus, the multiplex level of the address information of one sector is increased, and the reproducing reliability of address information is improved. A determination unit 6 determines and outputs the address value of this sector based on the four input values from the selection unit 5.
