  • Publication number: 20090300665
    Abstract: The disc device includes a casing, a drive unit, a disc processor swingably supported in the casing, and a first shift cam that swings the disc processor. The first shift cam restricts the swing of the disc processor to place the disc processor to each of an escape state, a clamp state, and a standby state. The standby state is a state in which the optical disc clamped to the turntable is allowed to keep a position apart from the opposing face of the casing while the disc processor is swung from the escape state to the clamp state. Accordingly, with no need to detect the position in the standby state with an arrangement such as separately-provided sensor, the disc processor can be placed in such a swinging state that the turntable can be controlled to be slightly rotated during the double clamp operation in a simplified arrangement. While preventing clamp failures, the optical disc can be favorably processed.

  • Publication number: 20090150911
    Abstract: A disc device includes a casing, a disc processor, a drive motor, a transfer unit and a disc clamper. The transfer unit transfers an optical disc while holding the optical disc by driving the drive motor. The disc clamper switches a drive transmission of the drive unit in accordance with a holding condition of the optical disc with different diameters by the transfer unit to pivotally move the disc processor. The drive of the single drive motor effects both the transfer of the optical disc and the pivotal movement of the disc processor. A timing for transferring the optical disc and a timing for pivotally moving the disc processor can be suitably adjusted in accordance with the diameter of the optical disc.

  • Publication number: 20080008183
    Abstract: It is an object of the present invention to provide a QoS controllable communication device and communication system. A device 114 such as a first IP telephone comprising a QoS control unit 121 of the present invention transmits first transmission control data to a device 111 such as a PC performing lower priority communication. The first transmission control data includes data for changing the communication path of the lower priority communication, and the PC 111, having received the first transmission control data, performs subsequent lower priority communication through the first IP telephone or other device 114, enabling the first QoS control unit 121 to perform priority control. Because the present invention employs widely used protocols such as ARP and ICMP, the device 111 receiving the control data does not need protocols specific to the present invention.

  • Patent number: 7313234
    Abstract: An encryption information determination section in a communication device negotiates an encryption algorithm to be used for encrypted communications with an encryption information determination section in a network camera, which is a communication counterpart. At this time, the encryption algorithm to be selected is varied depending on the CPU load of the communication device. That is, if the CPU utilization rate is high, a low-load encryption algorithm is selected, and if the CPU utilization rate is low, a high-load encryption algorithm is selected. A encryption/decryption processing section performs code processing using the encryption algorithm selected by the encryption information determination section.
