    摘要： Arithmetic operation is started by substituting an initial value x(0) for a logistic mapping x(t+1)=4x(t){1x(t)} which is a symmetrical nonlinear mapping. The resultant value is again input into the logistic mapping x(t+1)=4x(t){(1−x(t)}, based on an feedback x(t)=x(t+1). This operation is repeated to obtain time series x(t)−t. Isomorphic transform and quantization corresponding to the time series x(t)−t is obtained based on y(t)=[{2/&pgr;·arc sin {square root over (0)}x(t))}·2n] while a quantizing resolution n=1 is substituted for y(t)=[{2/&pgr;·arc sin {square root over (0)}x(t)}·2n]. A time series y(t)−t is determined from the obtained isomorphic transform and quantization. A spread spectrum signal having, as a period thereof, binary code sequence y(t) arbitrarily sampled from the time series y(t)−t is generated.

    摘要： A seal structure for connection sections, which facilitates installation and removal of a seal member from the connection sections. The seal member is placed in the connection sections between a first part and a second part. A first groove-ridge section is formed at the connection section of the first part, and a second groove-ridge section is formed at the connection section of the second part. The seal member has, on one face, a first fitting section fitting to the first groove-ridge section, and also has, on the other face, a second fitting section fitting to the second groove-ridge section. Press-fitting interferences in the wall-thickness direction are provided at the first and second fitting sections. The seal member has an extended section protruding radially outward from an annular body section where the first and second fitting sections are provided. The extended section protrudes to a position outside the connection sections of the first and second parts.

    摘要： A flow control valve is provided in a manner to be capable of locking a position of a differential screw easily without displacing a position adjusted valve element body. The valve element body is brought into or out of contact with a valve seat provided between a first port and a second port, and is connected to an operation member. The operation member is movably inserted into a cover and urged to a direction toward the valve seat by an urging member. A position of the operation member is adjusted by a differential screw, and accordingly a position of the valve seat is adjusted. A rotation member for exerting a rotation force on the differential screw is slidably mounted in the cover along a moving direction of the operation member without rotating. A locking portion is provided in the rotation member to engage with the cover without rotating when the operation member is slid along its moving direction.
