  • Patent number: 6940860
    Abstract: In one direction of transmission, an ATM switch establishes a virtual connection from any of its input ports to any of outgoing transmission links. Multiplexers receive and multiplexes user cells from the ATM switch into outbound cells having any one of all virtual channel identifiers assigned to the multiplexers and return the outbound cells to the input ports of the ATM switch, where they are routed through the virtual connections to the outgoing transmission links. In the opposite direction, the ATM switch establishes a virtual connection from any of incoming transmission links to any of its output ports. Inbound cells from the incoming links are first routed through the virtual connections in the ATM switch to demultiplexers, where they are decomposed into user cells for application to the ATM switch. Similar to the outbound cells, the inbound cells have any of the virtual channel identifiers assigned to the demultiplexers.

  • Patent number: 6285523
    Abstract: A small-sized light-weight tape cartridge to be installed in a recording and reproducing apparatus, for stably controlling a predetermined running speed of the tape. A clock signal is calculated from the photo-detected rotation of a reel in the cartridge by reading out from a ROM a count value per second corresponding to an accumulated counting value. The rotation speeds of the winding reel and the feeding-out reel in the cartridge are controlled so that the tape speed becomes a prescribed value. As a result, there is no need for a capstan motor, and the tape, a drum, the winding reel, the feeding-out reel and a control driving system are accommodated in a small-sized tape cartridge housing that is removably installed in the recording and reproducing apparatus.

  • Patent number: 6009331
    Abstract: In assignment of radio channels to terminals for communication with a switching office, one of currently idle channels can be assigned to a calling terminal by use of a channel state memory in the office which memory stores channel numbers and terminal information currently using channels. The office further includes a terminal memory for storing the maximum number separately predetermined for each of fixed and mobile types of the terminals assignable to the channels. The calling terminal is rejected to be assigned with any idle channel when the maximum number is equal to the current number of terminals currently using channels which are same as the type of the calling terminal. In another aspect, the terminal memory further stores information that the fixed type has a priority. An idle channel is assigned to a calling one of fixed type terminals even when the maximum number for the fixed type is equal to or smaller than the current number.
