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 variable circuit whose configuration can be easily modified to create an arbitrary Johnson counter, after creating the circuit. SOLUTION: At each input side of JK flip-flop sections 11-14, one connection selected from a twist connection with an output side of itself, a straight connection with an output side of flip-flop section on the previous stage, or an twist connection with output sides of two adjacent JK flip-flop sections on the lower stage is made, and at each input side of JK flip-flop sections 21-25, one connection selected from a twist connection with an output side of itself, a straight connection with the output side of flip-flop section on the previous stage, or an straight connection with output sides of two adjacent JK flip-flop sections on the upper stage is made.

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.
