Title: Fraudprofing medium and forgery judging method
Inventor: OKI YURI
IPC: G03G21/04
Filed: 1993-04-06
Abstract: PURPOSE:To make illegal reproduction impossible by blackening reproduced image by a constitution wherein the illuminating light of a reproducing device is reflected to different direction or its reflected light is shielded so as to not to reach the light receiving part of the reproducing device by means of flakes in the fraudproofing layer of fraudproofing medium. CONSTITUTION:The fraudproofing medium is constituted by laminating fraudproofing layer 3 and information recording layer 4 on the top surface of base material 2 in the order named. Further, the fraudproofing layer 3 is prepared by dispersing a large number of magnetic flakes 3b under the condition being oriented to the predetermined direction in the interior of transparent or translucent basic layer 3a. In addition, the information recording layer 4 is made of transparent or translucent material and records the predetermined information. Hereupon, if the fraudproofing medium 1 is reproduced with a reproducing device, the illuminating light incident from the same direction as the orienting direction of the flakes 3b passes through the fraudproofing layer 3 and falls upon the base material 2 and finally reflected by the base material 2. Furthermore, the light path of the reflected light is shielded by the flakes 3b, resulting in reaching no reflected light to the light receiving part of the reproducing device. Accordingly, image is reproduced under blackened state.

Refrigerants N 2 , CF 4  and CFCl 3  are supplied in order of a lower boiling point in the closed circuits of which each is completed by connecting the chamber, turbine and heat-exchanger. After an air heated in the heat-exchanger I is further heated by being compressed inside the compressor P, the air is led down via each low temperature turbine to boil a refrigerant inside each chamber. The produced refrigerant steam drives the turbines (a)W(c) to work. Thereafter the compressed air does its work within an expansion turbine (d) and some of it is liquefied and stored in a separator(D).
