Title: Encryption system and decryption system
Inventor: MATSUMOTO MAKOTO
IPC: G09C1/00
Filed: 2011-03-19
Abstract: <P>PROBLEM TO BE SOLVED: To provide an encryption system and a decryption system performing high speed processing safely.  <P>SOLUTION: A function selection means, for each block unit of a document from a document storage means, selects a function sequentially by pseudo-random numbers. A function execution means, using a block of the pseudo-random number sequence as a parameter in the selected function, converts the document to encrypt it. In the decryption system, an inverse function selection means, for each block unit of the encrypted document from the encrypted document storage means, selects an inverse function by pseudo-random numbers. An inverse function execution means, using a block of the pseudo-random number sequence as a parameter in the selected inverse function, converts the encrypted document to decrypt it. Since the respective functions are basic high-speed functions, the combined overall conversion is also carried out at high speed. Since both of the combination of the functions and the number of iteration can be changed, specification reinforcement in the future is facilitated. The execution order of the functions cannot be known, and consequently high safety is ensured.  <P>COPYRIGHT: (C)2011,JPO&INPIT

Title: Resistance welding method and resistance welding jig
Inventor: IKOMA NOBUKAZU
IPC: B23K11/11
Filed: 2011-03-30
Abstract: PROBLEM TO BE SOLVED: To prolong the life of a guide pin for use in resistance welding.SOLUTION: In resistance welding, an end portion 42a of a main metal piece 42 and a flange portion 43a of an inner casing 43 are welded together at contact surfaces thereof by applying a voltage between a first electrode 61 and a second electrode 80 while the inner casing 43 and the main metal piece 42 are pressed in directions toward each other. When a shearing stress due to the pressure is applied to a guide pin 70, since the guide pin 70 is made of ceramic, the guide pin 70 is more resistant to wear compared to a guide pin made of, for example, a phenolic resin. In addition, a clearance D is provided between a large-diameter portion 72 of the guide pin 70 and a guide-pin insertion hole 65b. As a result, the guide pin 70 is capable of shaking in the radial direction, so that the guide pin 70 can shake so as to partially absorb the shearing stress. The guide pin 70 is therefore more resistant to breakage compared to a guide pin made of ceramic that is not capable of shaking. Thus, the life of the guide pin 70 used in the resistance welding method can be prolonged.
