Title: Information communication method
Inventor: ASHINO YUUKI
IPC: H04L9/26
Filed: 1997-07-17
Abstract: PROBLEM TO BE SOLVED: To satisfactorily improve the cipher intensity and to inhibit the decoding within a finite time by forming an array of plural array elements having array numbers when the cipher value is concealed and decoded, designating an array number based on a chaos function to output the corresponding array element and accordingly deciding the cipher value. SOLUTION: A concealing key is inputted to a CPU 1c. An array setter 1b forms an array which contains 256 array elements having array numbers 0 to 255, for example, in response to a fact that the signal units of the text information have the value including the minimum 0 through the maximum 255 per byte. The CPU 1c sets the value of every array element contained in the setter 1b and then outputs the initial value of the chaos function to a chaos function generator 1a. Then the CPU 1c adds the cipher valine Ja-1 that is calculated in the last time to the outputted array element H ([256 X0]) and divides them by 256 to define this remainder QMOD256 as the cipher value.

Title: Nondestructive method for measuring number of photons
Inventor: HATANAKA NORIYUKI
IPC: G01J1/02
Filed: 1996-07-22
Abstract: PROBLEM TO BE SOLVED: To nondestructively measure the number of photons in an insulating layer by shifting the frequency of Josephson plasma oscillations from the resonance frequency of bound electromagnetic waves and measuring the standard deviation of the fluctuations of a very small Josephson junction current. SOLUTION: When a bias current is supplied from a current source 8, Josephson junction constituted of aluminum superconductors 5 and 6 and an oxide aluminum insulating layer 7 forms an electromagnetic wave bound to junction. When tunneling electrons pass through the layer 7, tunneling electron pairs and the electromagnetic field interact through the vector potential of the bound electromagnetic waves. When the interaction takes place, the quantum nature of phase particles are actualized and generate Josephson plasma oscillations at the very small Josephson junction. Therefore, the standard deviation of the fluctuation of a junction current which is caused by the interaction is measured with an ammeter 9 by shifting the frequency of the plasma oscillations from the resonance frequency of the bound electromagnetic waves.  Therefore, the number of photons in the insulating layer 7 can be measured nondestructively without affecting the joining action.
