  • Patent number: 7035226
    Abstract: Upon reception of a label request for a new flow, a path setup device searches label switched paths (LPSs) which have already been set up for comparison with a path contained in the label request. If there exists an LSP of the same path as that in the label request, the same label as that of the LSP is allocated. If no such LSP exists, a new label is allocated. An LSP is set up based on the allocated label.

  • Patent number: 6895008
    Abstract: In a label switching router placed at one end of an LSP set by using CRLDP, a bidirectional LSP setup TLV preparing portion prepares a bidirectional LSP setup TLV included in a bidirectional setup label request message transmitted in an up direction to a label switching router placed at the other end of the LSP. Based on an external bidirectional LSP setup request accepted by a bidirectional LSP setup accepting portion, a bidirectional LSP setup TLV analyzer analyzes the bidirectional LSP setup TLV in the message. When the message is received from the label switching router at the other end, a bidirectional LSP processor performs an LSP setup request in a down direction as opposed to the up direction. Based on the analyzed result by the bidirectional LSP setup TLV analyzer, and an explicit route preparing portion prepares an explicit route on which a router to be relayed in the down direction is prescribed.

  • Patent number: 5554966
    Abstract: An audio apparatus having a detachable control panel or operating-part main unit includes a microcomputer for detecting an OFF state of an ACC position of the ignition key, or the attached/detached state of the operating-part main unit. When such states are detected, normal operations of the microcomputer; namely, the operations to turn on an SWD V.sub.DD terminal and an A/D port and to set a KEY DATA terminal into a standby mode, are stopped intermittently in order to execute a low consumption process in which electric power is consumed only for holding information in memory in the microcomputer. When the microcomputer detects the OFF state of the ignition key or the OFF state of an installation detection switch and, an alarm ON state is set in the memory in the microcomputer, then an alarm sound is generated from a speaker for a predetermined time.

  • Patent number: 5515351
    Abstract: Disclosed is a CD player that ensures a setup operation and reproduction of information even when a partially recorded CD-R is set therein. The CD player sequentially performs the setup operation, starting from the first setup position located at the innermost periphery of the CD, predetermined for the setup operation, until the setup operation is complete at any of n-th (n=2, 3, . . . ) setup positions lying outwardly of the first setup position. If the setup operation is not completed even at an n-th setup position located at the outermost periphery of the CD, the CD player performs the setup operation again at at least one setup position lying inwardly of the n-th setup position. Also disclosed is a CD player that can discriminate a partially recorded, additionally recordable CD-R, and can execute the reproduction control for the PRD.

  • Patent number: 5508988
    Abstract: Method and Apparatus for playing a CD are designed to allow playback of a partially recorded disk of CD-Rs (CD-Recordable) having the DRAW (direct read after write) capability. It is determined if a target disk is a partially recorded CD-R recording medium. When a reverse command to return to a predetermined address of the recording medium to execute playback is input, the absolute time for information being reproduced is detected and it is then determined if the absolute time is within a predetermined actual pause period. When the absolute time is determined to be within the actual pause period, the reverse command is canceled. It is therefore possible to properly operate a servo system within that recording area of the recording medium where information has already been recorded, thereby allowing a return to a predetermined address associated with the reverse command. This prevents the loss of control of the servo system.

  • Patent number: 5471441
    Abstract: A CD player capable of detecting the recording end of a partially recorded CD-R (PRD) during playback. When an unrecorded area (URA) is detected, an address immediately before that of the URA is held and a setup is performed at the position of that detection. If the setup is unsuccessful, a setup is performed at a reference setup position, and when this setup operation is complete, playback starts from the held address position. When the playback from the position and detection of the URA are repeated a predetermined number of times, the held address position is discriminated as the recording end. According to a method of searching for the last piece of recorded information in the program area on a PRD, when reading failure occurs in a search, the pickup is moved back to a previous jump position to the occurrence of the reading failure.

  • Patent number: 5430698
    Abstract: A playing apparatus for a compact disc on which TOC information comprising at least first to third point data has repetitively been recorded in a lead-in area. A reading point by a pickup is moved in the lead-in area from the disc outer rim side in accordance with a TOC information reading command. When it is detected that the reading point was positioned to a recording track of third point data locating on the disc inner rim side in each of the TOC information, the reading point is jumped to the disc inner rim side by at least only two tracks. After that, the reading point is moved toward the disc outer rim side along the track, thereby reading the TOC information including the first, second, and third point data.

  • Patent number: 5394384
    Abstract: An operation mode is first selected in which tunes recorded in a digital audio disk are sequentially reproduced. Reproduction-undesired tunes are selected by operating a manipulator for stopping reproduction of a currently reproduced tune and starting the next tune during every reproduction of the reproduction-undesired tunes so that their numbers are stored in a memory. In subsequent reproductions, the number of each tune going to be reproduced is compared with the numbers of the reproduction-undesired tunes stored in the memory and the tune is skipped if its number is included in the stored numbers.

  • Patent number: 5359230
    Abstract: An on-vehicle electronic device includes a main body which is fastened to a vehicle and has a first terminal, and an operation unit which is detachably mounted in the main body and which has a second terminal electrically connected to the first terminal when the operation unit is mounted in the main body. The main body includes a reference power source applying a reference voltage to the first terminal, and a voltage detection unit for detecting a voltage applied to the first terminal. The main body further includes a mounting detection unit. The mounting detection unit determines, based on a difference between a first detection voltage detected by the voltage detection unit when the operation unit is mounted and a second detection voltage detected by the voltage detection unit when the operation unit is not mounted, whether or not the operation unit is mounted and electrically connected to the main body via the first and second terminals.

  • Patent number: 5173887
    Abstract: A method for controlling the operation of a disk player pickup control system includes the steps of reading position data representing the present position of a pickup from a disk, calculating the distance from the present position to the home position of the pickup according to the position data thus read, and moving the pickup to the home position according to the distance thus calculated. The above-described method for operating the control system is particularly advantageous in that it allows the pickup of a disk player, which does not include a mechanical limit switch, to be moved to the home position.
