Title: Thin magneto-optical film
Inventor: UMEMURA SHIZUO
IPC: G11B11/10
Filed: 1988-02-05
Abstract: PURPOSE:To increase the Kerr rotating angle of a thin magneto-optical film without degrading the reflectivity thereof by alternately laminating >=2 layers of thin ferromagnetic films and thin dielectric films on a substrate, thereby forming the thin magneto-optical film. CONSTITUTION:The thin magneto-optical film is formed on the substrate by alternately laminating >=2 layers of the thin ferromagnetic films with consists of an amorphous rare earth-transition metal alloy and has 30-260Angstrom , more preferably 80-160Angstrom  thickness and the thin dielectric films which consist of a nitride, sulfide or fluoride and have <=2.5 refractive index and <=0.2 attenuation coefft. on the substrate. The Kerr rotating angle can then be made larger than in the case of the signal layer; in addition, the C/N of magnetic recording can be increased without degrading the reflectivity so much. Since the rare earth metals are easily oxidizable materials, the material consisting of the nitride, sulfide or fluoride is used for the thin dielectric films. The Kerr rotating angle is thereby increased without degrading the reflectivity of the thin magneto- optical film.

Title: File security protection method
Inventor: ITO YUJI

Filed: 1993-02-16
Abstract: PURPOSE:To systematically and easily protect data on a file by adding a data class and a security level to the file attribute and prescribing the data class to which a user can access and the upper limit of the security level. CONSTITUTION:When the user starts access to a system, a user management system 16 retrieves a user management data base 19 and reads an access right list obtained by combining the data class which the user can access and the upper limit of the security level into a memory. When the user requests the allocation of the file, a file management system 11 retrieves a file management data base 10, reads the data class and the security level of the file, recognizes that the data class is included in the access right list of the user and the security level does not exceed the upper limit of the security level of the user, and denies an allocation request when they violate the rules. Thus, a relation between data on the file and the user is arranged and systematic security which is easily managed is realized.

Title: Compensation estimation encoding circuit for inter-frame motion
Inventor: OKAJIMA MASAYUKI
IPC: H01L41/22
Filed: 1985-02-15
Abstract: PURPOSE:To encode a signal without converting the transmission order of a picture signal by calculating an estimated value from the output of a frame memory circuit and that of a converting circuit which outputs the output signal of a motion vector detection circuit after it converts the transmission order. CONSTITUTION:It is assumed that the size of one block is set to m-number of pictures in the horizontal direction and n-number of lines is the vertical direction, and k-number of blocks are arrayed. Where the encoding period of the picture signal is T, the motion vector detecting circuit 8 outputs a vector signal at every block during the period of (mXn)T as shown in figure (a). The converting circuit 9 converts the transmission order of the vector signal in such a way as shown in figure (b). Namely, k-number of vector signals are outputted during the encoding processing period of one line, and the outputting is repeated n-times. The output order of the vector signal outputted in such a way corresponds to that of a picture signal inputted to an encoding circuit, and accordingly the signal can be encoded without changing the order of the input signal from the encoding circuit.
