Abstract: PROBLEM TO BE SOLVED: To provide a board for transmission lines whereby the value of the impedance of a transmission line can be made higher than conventional ones and can be set precisely to a desired one. SOLUTION: In the board for transmission lines, a first transmission line 1a having a nearly corrugated pattern is provided on one side of a base 5a, and a second transmission line 2a having a nearly corrugated pattern is so formed on the other side of the base 5a that it is in line symmetry with the first transmission line 1a with respect to a line and it intersects the first transmission line 1a continuously and stereoscopically.

Abstract: PROBLEM TO BE SOLVED: To provide a simulator of chemical reaction in which the amount of each substance to be changed by chemical reaction can be easily simulated even when many kinds of substances are used for simulation and simulation programs can be easily revised and to provide a method for simulating chemical reaction. SOLUTION: The amount of each substance to be changed by biochemical reaction is simulated so that each of reaction executing circuits H1-Hn decreases the count number of the substance counter B1-Bm corresponding to each substance before chemical reaction and increases the count number of the substance counter B1-Bm corresponding to each substance after chemical reaction according to each reaction rate to be adjusted by each of random number generators R1-Rn and each of enzyme counters K1-Kn.

Abstract: PROBLEM TO BE SOLVED: To provide a random number generating circuit capable of surely generating more complete random numbers in short time. SOLUTION: Cascade connected C gates 1, 2 detect a falling time point of a first rectangular wave F at a rising time point of a second rectangular wave S and afterward, cascade connected C gates 3, 4 detect a rising time point of the first rectangular wave F at the rising time point of the second rectangular wave S and afterward, when a value of the first rectangular wave F is 1 at the rising time point of the second rectangular wave S, a NAND gate 5 outputs zero and when the value of the first rectangular wave F is zero at the rising time point of the second rectangular wave S, a NAND gate 6 outputs zero.

Abstract: PROBLEM TO BE SOLVED: To provide a network management device that can realize high-speed broadcast even when a network is dynamically changed and to provide a network system employing the device. SOLUTION: The network management device 200 measures a communication speed of a communication network 100, controls a random connection rate among nodes 11 to 1n so as to increase a broadcast speed depending on the measured communication speed and the number of communication channels 21 to 2m and decides a connection state among the nodes 11 to 1n so as to attain the random connection rate.

Abstract: PROBLEM TO BE SOLVED: To provide a data transmission system that can reduce the area of a circuit board on which a transmission line is formed and enhance the data transfer speed, and to provide a data transmitter and a data receiver. SOLUTION: When a transmission request transmission section 11 transmits a transmission request to a receiver 2, a transmission request reception section 21 receives the transmission request via a data line D1, and a transfer clock generating section 24 transmits a transfer clock to a data transmission section 12 via a control line C1. In this case, the data transmission section 12 transmits transmission data in n-bits to a data reception section 22 via data lines D1 to Dn synchronously with the received transfer clock, and the data reception section 22 receives the n-bit received data sent from the data transmission section 12 synchronously with a delayed transfer clock outputted from a transfer clock delay section 23.
