摘要： PROBLEM TO BE SOLVED: To collect information on a material desired by a visitor in an exhibition without needing a troublesome operation. SOLUTION: A distribution device 3 for distributing material request information by inducing an electric field in a human body is installed at an exhibition booth, and a visitor 100 carries a collection device 2 for receiving the material request information. By the visitor 100 simply touching a communication electrode 31 of the exhibition booth (a material request panel), material request information on the material desired by the visitor 100 can be accumulated in the collection device 2. Since the material is sent later based on the material request information accumulated in the collection device 2, the visitor 100 does not need to receive the material at the respective exhibition booths, thereby reducing the burden on the visitor moving around the exhibition site. In the meanwhile, an exhibitor does not need to stock a large amount of materials at their exhibition booth, thereby enhancing space efficiency. It is also possible to reduce the staff dedicated for distributing materials or collecting questionnaires. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a high-speed and compact QoS circuit, especially a WFQ circuit for performing queue control. SOLUTION: The WFQ circuit 100 using a weighted round robin has a storage means for storing the values of quotient counters corresponding to each of a plurality of input ports and the value of a remainder counter. The WFQ circuit 100 selects the quotient counter of the minimum value in the quotient counters, transmits a transmission request from an input port corresponding to the selected quotient counter to a later-stage circuit, and updates the values of the quotient counters except the selected one to values obtained by subtracting the values of the selected quotient counter from them. A value obtained by adding the frame length of input from the input port corresponding to the selected quotient counter to the value of the remainder counter corresponding to the input port is divided by the value of a prescribed weight corresponding to the input port. The value of the selected quotient counter is updated by the quotient of a divided result. The value of the remainder counter corresponding to the input port is updated by the remainder.

摘要： PROBLEM TO BE SOLVED: To provide an optical transmission circuit which has solved the problems in the conventional art in which a delay time (time from clock input to data rewriting) in a retiming circuit varies dependent on temperature, power supply voltage and deterioration with time, causing degradation of a waveform quality of output pulses because deviation from a phase optimization point cannot be corrected automatically by the variation of the delay time owing to subsequent variation factors even if offset voltage is adjusted with the initial delay time, and which can automatically optimize a relative phase between two modulators without requiring a high speed timing extraction circuit or a phase comparator.
SOLUTION: The optical transmission circuit of the invention includes a phase modulator which modulates a phase with an output from a differential encoding circuit, and an intensity modulator which modulates a signal intensity for phase modulation light from the phase modulator with a clock signal, so that a relative phase between the phase modulator and the intensity modulator can be optimized to maximize the average intensity of the output light from the intensity modulator.
