IPC: G09C1/00
Filed: 1998-12-11
Abstract: PROBLEM TO BE SOLVED: To obtain keys being safe as keys of an elliptic curve cipher at high speed. SOLUTION: This key generating method decides (p) with which y2=x3+1 (mod p) becomes safe. This method generates a random number U which has w/2+1 bits and in which the residue is 1 when it is devided by 6 and a random number V which has w/2 bits and is divisible by 6 with respect to the size w of (p) and the method calculates U2-UV+V2=W and when W is not a prime number, it returns to the generating of U and V and when W is a prime number, it decides candidates of the prime number method, 12W+1±6U, 12W+1±(6U-V), 12W+1±6V and when these 6 candidates are prime numbers, the method outputs them as (p) and when they are not prime numbers, the method returns to the generating of U and V.

Then, after the water feed process, the back washing with the permeated water and a gas is performed at first. After the back washing with the permeated water and the gas, the operation is immediately returned to the water feed process and the permeated water side is filled with the permeated water to immediately perform the back washing. The process is continuously repeated 100-1000 times.

Filed: 1991-12-24
Abstract: PURPOSE:To provide the subject dust-proof wear capable of exhibiting necessary and sufficient dust-proof properties in a clean room of a relatively low cleanness grade in spite of its very simple structure. CONSTITUTION:An air-permeable and dust-proof lining 5 is attached on the wrong side of the back 1b of a wear body 1 and an opening part 6 is made at a position corresponding to the neighborhood of the lower end part of the lining 5 in the wear body 1 to form an air-flow path communicating from the inside of the wear body 1 through the lining 5 and the opening part 6 to lower outside part. As the air in the inside of the wear body 1 is discharged through the lining 5 and the opening part 6 to the lower outside part of the wear body 1 by a natural motion of a worker wearing the dust-proof wear, the dust- containing air in the inside of the wear body 1 can be prevented from being discharged especially from the neck part 1a to the front side.

IPC: H04L12/18
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To attain efficient file transfer optimum for the using style of a user by setting plural multiplicities, requesting the file transfer when all the multiplicities have margins, changing a client when any one of multiplicities reaches a critical value and waiting the end of processing of the client when all the clients have no margin.

When it is judged that the multiplicity 2 has the margin, the multiplicity 2 is counted up just for 1. Next, it is discriminated whether a multiplicity 2 at the current time point is smaller than its maximum value MAX3 or not.
