Title: Key distribution device
Inventor: OKAMOTO EIJI
IPC: H04L9/06
Filed: 1984-07-24
Abstract: PURPOSE:To distribute simply a different key every time by detecting a key request signal from a station executing ciphering communication, converting a digital pattern corresponding to a station address depending on a random number and transmitting the converted pattern to the station. CONSTITUTION:When an interface 204 gives a key request data from a station executing ciphering communication to a microprocessor 201, it generates a random number R and gives it to a power remainder circuit 203 and gives a digital pattern corresponding to an address of a key request station stored in the memory 202 and an opposite station of ciphering communication to the circuit 203. The circuit 203 converts the digital pattern depending on the random number R and gives the pattern to the microprocessor 201. The microprocessor 201 forms two public key distribution data from the data from the circuit 203 and transmits them to a communication network from the interface 204.

Abstract: PURPOSE:To easily obtain the title single crystal ceramic at a relatively low temp. while facilitating the control of the solid phase growth by opposing a single crystal to a polycrystal, fixing both crystals with an adhesive layer added with an abnormal particle growth accelerating element, and heating the material. CONSTITUTION:The flat surface of a polycrystal ceramic is opposed to the surface of a single crystal ceramic having almost the same composition as that of the polycrystal ceramic. Both surfaces are fixed with an adhesive layer contg. an abnormal particle growth accelerating element. The material is then heated, hence the adhesive layer beings to diffuse, and the material is treated at a bonding temp. where the flat surface of the polycrystal ceramic and that of the single crystal ceramic are brought into contact with each other. Then the material is heated at a temp. lower than the temp. at which abnormal particles of the polycrystal ceramic begins to grow, higher than the bonding temp., and close to the diffusion and solid phase growth equilibrium conditions, and the solid phase is grown to obtain the desired single crystal ceramic. The behavior of the abnormal particle growth of the polycrystal is remarkably changed by the presence of impurities. Although the particle growth is suppressed by the presence of a trace amt. of some impurities, the abnormal particle growth is accelerated by the presence of >=200ppm impurities.
