  • Patent number: 6085238
    Abstract: A virtual LAN system forms a virtual group which is based on elements having physical attribute or logical attribute and constituting a virtual LAN, sets a client address and priority of the virtual group in a virtual group registration table, and allocates unicast and broadcast traffic bands in group units.
    Type: Grant

  • Patent number: 5144295
    Abstract: An interruption processing system in time division multiplex transmission system executes at a central control unit a group access for accessing in batch respective groups of a plurality of terminal units in response to at least part of superior bits of a specific address for one of the terminal units which requests an interruption, causes inferior bits of the address returned from the terminal unit requesting the interruption to the central unit, and allows the central control unit to specify the interruption requesting terminal unit on the basis of the superior and inferior bits of the address. Extremely rapid specification of the interruption requesting terminal unit is thereby made achievable, and the operational response time of the transmission system can be shortened to a remarkable extent.

  • Patent number: 4112407
    Abstract: A fire sensing device for actuating associated fire alarm system having a heat receiving plate member of improved heat receiving efficiency for rapidly transmitting any abnormal heat received from environmental atmosphere to a heat-responsive switching means thermally connected to the plate member to actuate the alarm system promptly and reliably is provided. In order to enlarge surface area, the heat receiving plate member has many fins comprising elongated bridging parts defined by adjacent ones of many parallel slits made in the plate member and twisted about elongated axis preferably by an angle of 40.degree. to 60.degree. with respect to the plane of the plate member so as to be raised at both longitudinal edges from the member on its both sides, whereby abnormally heated air passing along a surface or surfaces of the plate member is caused to flow along the fins through or into the slits to rapidly and efficiently transmit its heat to the plate member.
