Title: Key generating system
Inventor: TSUJII SHIGEO
IPC: G09C1/00
Filed: 1989-01-26
Abstract: PURPOSE:To generate a crystographic key having the high confidentiality which does not require the list of public information by subjecting the 1st number determined dependently upon the identification information of the other person with whom the key is to be shareably possessed to power multiplication with the predetermined secret 2nd number, thereby generating key. CONSTITUTION:The ciphering person of data is designated as a user (i) and a decoding person as a user (j). However, there is possibility of i=j in the case of a file cipher. A terminal 103 calculates the key Kij by the equation 4 from the information written on an IC card 101 when the user (i) inserts the card into a card reader 102. Here, (Yj1, yj2,...yjn) is calculated by using the equation (yj1, yj2,...Yjn)=f(IDj) from IDj of the other user j. The user j obtains Kji equal to Kij if the similar calculation is made (the calculation is made by exchanging i with j).

A photo film cartridge is taken out from the unit main body of the film unit with a lens collected in a processing laboratory according to a print request. The photo film cartridge and the unit main body are set on a magnetic recording device to read base data and photographing data from the IC memory through a connector exposed to the outside of the unit main body, and the read data is recorded in a magnetic recording layer of a photo film.  At the time of conducting print processing, the above magnetic recording data is read out and utilized for print processing.

Title: Wiring device, heating element, fixing device, and image-forming device
Inventor: KARIBE TAKAAKI
IPC: G03G15/20
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To suppress the generation of a crack at a connection part by using a high-level silver/palladium alloy with palladium content as the main constituent of a conductor pattern on a wiring substrate and setting the main constituent of a terminal pattern that is formed while it is overlapped to the conductor pattern to a lower, same alloy with palladium content.

Abstract: PURPOSE:To improve the bending strength and the resistance to deformation bin constructing a cabinet by bending the painted steel sheet by forming abutment sections in the rear flanges which extend from both sides to make contact with the rear side of the side panels and horizontal panel and extend near to and cut off by the bends. CONSTITUTION:The rear flanges 6 have an abutment section 13 which extends from either side to contact the rear side of the side panels and horizontal panel and extends near to and cut off by the bends T1, T2. The proximities N1, N2 come close to each other by the bending of the painted steel sheet, and the height difference section 11 overlaps the rear of the fold 10. Because of this, the extensions are aligned with the edge of the fold 10 or the line 11a without contacting or overlapping the fold 10 or the height difference section 11 when the flanges are bent, and the abutment section 13 can make contact well with the respective rear sides.

Title: Magnetic recording medium
Inventor: MATSUYAMA HIDEO
IPC: G11B5/738
Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To prevent the increase of medium noise even in low density recording by disposing one or more antiferromagnetic films or ferrimagnetic films between an underlying film and a ferromagnetic film and further disposing one or more antiferromagnetic films or ferrimagnetic films between the ferromagnetic film and a protective coat. SOLUTION: An underlying film 2, an antiferromagnetic film 12, a ferromagnetic film 3, an antiferromagnetic film 13 and a protective coat 4 are laminated on a substrate 1 to obtain the objective magnetic recording medium. Since magnetic interaction occurs at the interface between each of the antiferromagnetic films 12, 13 and the ferromagnetic film 3 and increases the coercive force of the interface of the ferromagnetic film 3, the spin of the ferromagnetic substance in the direction in which a magnetic field is applied is inhibited. This means the increase of the interface anisotropy of the ferromagnetic film 3 and corresponds to the increase of coercive force. Inverse magnetic domains are not formed in bits in low density recording and medium noise is reduced.

Then a field detection signal is outputted to a timing signal generating circuit 12 and proper drive control for an LCD cell 13 is implemented for each field. Thus, a clear picture is displayed even when synchronization is disturbed without causing a delay for field detection.
