摘要： In a color television camera, a color separation optical system includes a first relay lens behind a taking lens of the camera, color separation optical elements such as prism blocks or dichroic mirrors, and a set of second relay lenses. Image pick-up tubes for three colors are provided behind the second relay lenses. The pick-up tubes are mounted in coil assemblies. Each coil assembly is provided with a rotating device for conducting a position adjustment of the tube with respect to the associated second relay lens to make perfect registration between images of the three tubes. A focus adjusting device for conducting a focus adjustment between each second relay lens and the associated image pick-up tube is provided in each second relay lens. The focus adjusting devices are operable from outside the camera for sliding the second relay lenses in the direction of their optical axes.

摘要： A color separation optical system for a color television camera of relay lens type in which a set of color separating optical elements are provided between a single first relay lens and three second relay lenses for three primary colors. The first relay lens is located substantially on the image plane of the taking lens of the television camera. A field lens is provided between the taking lens and the first relay lens. The power of the field lens is determined according to the focal length of the taking lens. The field lens is removed when the exit pupil of the taking lens is registered with the entrance pupil of the first relay lens. In this case, the first relay lens is axially moved toward the taking lens to make the front focal plane of the first relay lens registered with the image plane of the taking lens. The axial movement of the first relay lens is conducted by means of a mechanism which is operable from outside of the television camera.

摘要： A transmission repeater has a function of recovery to normal out of the deadlock state of auto-negotiation sequence between switches. The switches exchange auto-negotiation configuration codes via first and second transmission repeaters for a state transition. The first transmission repeater monitors auto-negotiation configuration codes among data transmitted from the opposed switch, and when detecting more than a predetermined number of configuration codes of auto-negotiation having been transmitted during a given period of time, determines that the auto-negotiation sequence between the switches is at a deadlock, and reports it to the second transmission repeater, which then disconnects optical signals from the sending end of the second transmission repeater to the switch for more than twice the propagation time of signals between the switches, thus resolving the deadlock between the switches.

摘要： In a trunk network, each node, when notified from another node of a change in the state of a group to which external connection ports belong, changes the states of the external connection ports to cause external devices to detect the failure of the transmission route. A port state monitor unit classifies external connection ports into groups in advance and stores the correspondence of the external connection ports and the groups. The port state monitor unit then detects changes in the states of external connection ports. When a change of the state of any external connection port is detected in the port state monitor unit, a group state management unit reports state information that includes the states of groups that correspond to the external connection port to other nodes that make up the trunk network. Upon receiving state information from any other node, the group state management unit, in accordance with the states of groups that are included in the state information, changes the states of external connection ports that belong to these groups.

摘要： Where each of switches opposed to each other detects optical-signal shutoff or optical-signal deterioration on the reception side of its port, the switch brings a link of the port down and outputs an auto-negotiation configuration code, as an LAN signal. Upon receiving the LAN signal transmitted from the switch, a repeating-transmission apparatus transmits the transmitted signal to an auto-negotiation monitor. The auto-negotiation monitor performs code analysis for the transmitted LAN signal. Where the auto-negotiation monitor detects that the transmitted LAN signal is the auto-negotiation configuration code, it notifies a monitor apparatus that “The switch detects a failure and the link is down.”, as an alarm.
