Abstract: <P>PROBLEM TO BE SOLVED: To generate random numbers having higher safety for a random number generator which is used for ciphering algorithm or the like.  <P>SOLUTION: A random number generator 10 is provided with a pseudo-random number generating section 12 which is used to output a plurality of different pseudo-random number sequences, a physical random number generator 14 which generates physical random numbers and a switching section 16 which is used to switch the pseudo-random number sequence of random numbers outputted by the section 12 based on the physical random numbers generated by the generator 14 and the generator 12 sets the output of the section 12 as output random numbers. Since the plurality of different pseudo-random number sequences are switched by the physical random numbers and outputted, predictability of the random numbers is reduced compared with a conventional random number generator which utilizes only pseudo-random numbers. Since the physical random numbers are not directly used as output random numbers , adverse effect on the predictability of output random numbers is relatively made small compared with a conventional device even if some kind of operation is applied to the physical random number generating means from the outside.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To provide a valve mechanism which can surely close a fluid even with a simple structure and can arbitrarily change a flow rate of the fluid passing through the mechanism depending on the pressure applied thereto.  <P>SOLUTION: When pressure is applied to the fluid in a fluid reservoir 142 by pressurizing the reservoir 142 of a container body 140 in the valve mechanism 10, a flow path of the fluid is formed since the maximum outer diameter of a valve 21 becomes smaller than the inner diameter of an opening due to flexibility of the valve 21 of a valve member 20 to cause the valve 21 to separate from the inner peripheral surface of a supporting member 30 when the pressurized fluid is made to flow in from distributing paths 31. On the other hand, if the pressurizing force to the fluid reservoir 142 is canceled, the inner peripheral surface of the supporting member 30 again comes into contact with the valve 21 of the valve member 20. Thus the air can be prevented from entering the reservoir 142 through the opening 32.  <P>COPYRIGHT: (C)2004,JPO
