Title: Ciphering method, decoding method, recording and reproducing device, decoding device, decoding unit device, recording medium, manufacture of recording medium and method of managing key
Inventor: KATO TAKEHISA
IPC: G06F21/62
Filed: 1997-05-27
Abstract: PROBLEM TO BE SOLVED: To protect a copyright from piracy in preventing illegal copies by ciphering a data with a 1st key and ciphering this 1st key with predetermined plural 2nd keys. SOLUTION: A 2nd session key Sk' is generated by a session key generating circuit 111, and is decoded by a decoding circuit 112 with a master key Mk and then ciphered by a ciphering circuit 104 with the key Mk, so that the key Sk' generated by the circuit 111 is obtained. Then, a 1st session key ciphered by the key Mk recorded on a DVD 101 is ciphered by the key Sk' and is sent to the circuit 112, where this key is decoded by the key Mk to obtain the 1st session key Mk. Then, a data ciphered by a key Sk recorded on the DVD 101 is read out, and is processed by a demodulation/ error correction circuit 118, and afterward, the received data is decoded by the circuit 112 with the key Sk to obtain a plain styled data. Thus, the decoded data does not flow in a CPU.BUS 110, and for example, even when this data is stored in a storage medium, the data cannot be reproduced to be used. Consequently, an illegal act of making unauthorized copies is prevented to protect the copyright from piracy.

Abstract: PURPOSE:To produce stably a fine metallic wire while preventing clogging of a nozzle for discharging a molten metal by providing a specifically constructed moving shutter to said nozzle in the stage of forcing the molten metal to flow down in the form of fine flow on a single or twin rolls under rotation to cool quickly and producing the fine metallic wire. CONSTITUTION:The molten metal in a nozzle body 4 is pressurized by the high pressure inert gas admitted into said body through an inlet 13 and is ejected from plural slit nozzles 2 onto a roll 1 under rotation and is cooled quickly by the roll 1, by which fine metallic wires 14 are continuously produced. Each nozzle 2 is made into a slit shape slender in the rotating direction of the roll and is attached with a refractory shutter 3 rotating around a shaft 3' in the bottom of said nozzle. The part of the slit to be shielded by the shutter 3 is made small to increase the nozzle hole in the beginning of casting so that the molten metal flows downward without clogging the nozzle port. The shutter 3 is then rotated reverse to throttle the aperture of the slit nozzle to an intended diameter so that the fine stream of the molten metal flows downward continuously. The fine metallic wire 14 is thus produced.
