    摘要: A broadband radio communication system and method therefore that conducts communication on a plurality of narrowband channels obtained by dividing a broadband channel into a plurality of narrowband channels. The invention provides a first radio communication terminal which sets transmission conditions of at least part of the narrowband channels and transmits a wireless packet on the narrowband channels of which the transmission conditions have been set, and a second radio communication terminal which receives the wireless packet from the first radio communication terminal, measures the line qualities of the narrowband channels and transmits measured line quality information to said first radio communication terminal. The first radio communication terminal receives the line quality information, sets new transmission conditions based on the line quality information, and transmits a wireless packet to the second radio communication terminal through the narrowband channels under the new transmission conditions.

    摘要: An asynchronous transfer mode switching system for improving switching throughput and averting complicated and difficult timing design. In operation, synchronous cell strings from external transmission lines are converted to asynchronous cell strings which are switched by a space-division switch array. The switched asynchronous cell strings are reconverted to synchronous cell strings for output onto external transmission lines. The space-division switch array comprises a plurality of unit switches in stages, each unit switch having input terminals and output terminals. The unit switches each include a timing control circuit that causes a switching operation to start upon detecting two states concurrently: a stored state of a cell to be switched, and a storage-ready state of a destination for the switched cell. The scheme allows the system to operate in an asynchronous manner.

    摘要: A superconducting device may include a superconducting weak link equipped with plural superconducting devices that are used as input-output terminals formed on the same plane and at least one current source for applying current to at least one of these superconducting electrodes. A superconducting device suitable for high integration can be realized as it enables structuring of a superconducting weak link 1 equipped with plural superconducting electrodes 101, 102, 103 and 104 that can be used as input-output terminals and changing symmetry of superconducting electrode arrangement through the form of a normal conductor 201 which is forming a superconducting weak link. In addition, when this superconducting device is used as a quasi-particle injection type device, a superconducting device with plural superconducting electrodes that can be used for a gate electrode, drain electrode or control electrode can be realized. Further, a superconducting device equipped with new functions (e.g. motion as a neuron device) which are capable of high integration can be realized by utilizing these characteristics. Furthermore, being a proximity effect type, superconducting weak link has an advantage of realizing an ultra highspeed, low electricity consuming switching device.

    摘要: A Josephson signal detector is presented which includes (1) a sensor with at least one Josephson junction (e.g., a SQUID) and (2) a comparator (e.g., an analog-to-digital converter); a measurement system using such detector; and a method of using such detector and measurement system. The detector can be, e.g., a digital SQUID. The detector can also include a readout circuit for reading out the output of the comparator. In one aspect of the invention, the sensor, or both the sensor and readout circuit, are powered by a DC current source. Through use of the DC current source, it is possible to provide, e.g., a digital SQUID, having reduced crosstalk and reduced fluctuation of ground potential, and which is kept from an increase in noise or a miss operation.
