The present invention provides a compound having melanocortin receptor agonist activity or antagonist activity, which is a novel biaryl compound represented by the formula (I): 

Biaryl compound and use thereof

In a backup systemora controllercontrols operation of a multi-source audio apparatus MMSA. An operation status holderholds operation status information Dbk of the multi-source audio apparatus MMSA. A non-volatile memorystores the operation status information Dbk. A capacitoras a power storage means stores part Pt of operating power. An operating power detector(Sps) detects whether or not the operating power is being supplied. An operation status information write deviceselectively writes the operation status information Dbk into the non-volatile memorydepending on whether or not the operating power is being supplied.

Backup system for multi-source audio apparatus

In an optical disk high-speed replaying/recording apparatus, a first read data quality determining section determines a quality of read second units of digital data. Upon determination that the quality of the second units of digital data is low, a first re-reading section re-reads the first units of digital data tracks, sectors, or data blocks in the second units at a third replay speed obtained by subtracting a first predetermined speed from a second replay speed. With this, the optical disk can be replayed at a speed higher than the normal replay speed, and reproduced data can be recorded on a writable optical disk except defective data caused by reproduction defects.

High speed recording and reproducing for optical disk device of different format

A DVD audio signal reproducer reproduces a DVD to generate a DVD reproduced audio signal. A reproduced signal determiner determines whether the DVD reproduced audio signal is a 5.1-channel digital surround audio signal or a 2-channel digital audio signal, and generates a determination signal. If the determination signal indicates that the DVD reproduced audio signal is a 5.1-channel digital surround audio signal, a digital surround effector converts the DVD reproduced audio signal to a 2-channel digital surround audio signal.

Multi-source surround audio apparatus

In a multi-session disc including both audio session and data session, the data session is correctly recognized and accessed. The reproducing apparatus is a reproducing apparatus of a multi-session disc mixing a session of first type recording first data and a session of second type recording second data different from the first data, comprising an optical pickup for accessing the session of first type and the session of second type, a judging unit for judging a type of the session accessed by the optical pickup, and a limiting unit for limiting the session of first type to a reproducible session when the session of second type judged by the judging unit is present at an access position after the session of first type.

Reproduction apparatus

A reproducing apparatus capable of reproducing the data to be reproduced correctly by judging the lead-in region of first session on a multi-session disc. The reproducing apparatus reproduces a multi-session disc composed of a plurality of sessions, each comprising a lead-in region recording index information including the information of reproduction start time measured from the disc innermost peripheral position, program region recording program tracks storing contents to be reproduced, and lead-out region, corresponding to the start position of each program track stored in the multi-session disc. This reproducing apparatus comprises an optical pickup for reading out the index information of specified session, and a session judging unit for judging if the lead-in region of the specified session is the lead-in region of the first session of the multi-session disc or not, on the basis of the information of the reproduction time included in the index information being read out by the optical pickup.

Reproducing apparatus

Cyclic pentapeptides are disclosed having the following formula (I)-Cyclo(-A -A -A -A -A -)-wherein A , A , A , A and A are amino acid residues. The pentapeptide has amino acid residues in positions 1-2-3 to form a &ggr;-turn, and amino acid residues in positions 3-4-5-1 to form a &bgr;-turn in combination with the &ggr;-turn. D-&agr;-amino acid residues are selected for A , A , and A and L-&agr;-amino acid residues are selected for A and A . Compounds having &ggr;-turns and &bgr;-turns can be synthesized, regardless of the kinds of amino acid residues, and it is possible to synthesize compounds in which desired amino acid residues are introduced into sites of &bgr;-turn and &ggr;-turn based on their importance from the viewpoint of biological activity. The present invention is therefore available for design of compounds having biological activity.

Cyclic pentapeptides are disclosed having the following formula (I) --Cyclo(-A.sub.1 -A.sub.2 -A.sub.3 -A.sub.4 -A.sub.5 -)-- wherein A.sub.1, A.sub.2, A.sub.3, A.sub.4 and A.sub.5, are amino acid residues. The pentapeptide has amino acid residues in positions 1-2-3 to form a .gamma.-turn, and amino acid residues in positions 3-4-5-1 to form a .beta.-turn in combination with the .gamma.-turn. D-.alpha.-amino acid residues are selected for A.sub.1, A.sub.3, and A.sub.5 and L-.alpha.-amino acid residues are selected for A.sub.2 and A.sub.4. Compounds having .gamma.-turns and .beta.-turns can be synthesized, regardless of the kinds of amino acid residues, and it is possible to synthesize compounds in which desired amino acid residues are introduced into sites of .beta.-turn and .gamma.-turn based on their importance from the viewpoint of biological activity. The present invention is therefore available for design of compounds having biological activity.

A recording and reproducing apparatus of the present invention has reproduction change detector for receiving information indicative of a detection of a reproduction operation from an in-reproduction detector, and a record change detector for receiving the information indicative of the detection of the reproduction operation of recording parts from in-record detector, thereby having excellent operability by simple switching operation.

Recording and reproducing apparatus with selectable I/O control

A digital signal reproducing apparatus capable of reproducing video and audio information from a compact disk without losing the beginning of the video and audio information even when reproducing disks wherein the video and audio information are recorded simultaneously from the first block of any specified selection, said apparatus includes a reproduction position detector for outputting the current reproduction position based on the subcode information. An offset reproducer offsets the disk track being reproduced to a track position before the current reproduction position after accessing the specified reproduction position, then resuming reproduction. First and second shift controllers outputs first and second shift position information obtained by adding or subtracting a constant value to the access position information when initial access is completed. A digital muting canceler cancels audio muting when the reproduction position passes the first shift position; and a video muting canceler cancels video muting when the reproduction position passes said second shift position.
