Filed: 1999-09-22
Abstract: PROBLEM TO BE SOLVED: To provide a new deciphering method for product sum open key ciphering and a safety evaluating method for product-sum open key ciphering. SOLUTION: A plaintext divider 2 divides a plaintext (m) into divided plaintexts, open keys of an entity (b) found according to the multiplication format of a secret key are read out of an open key storage part 3, and a ciphertext C is generated by a cipherer 4 by using those divided plaintexts and open keys and sent to the entity (b) through a communication line 1. A decipherer 5 of the entity (b) deciphers the ciphertext C into the original plaintext (m). At the time, some of the secret keys are found by LLL algorithm using two pairs of two successive open keys and some of the found secret keys are used to decipher the ciphertext C into the original plaintext (m).

Title: Fuel injection nozzle
Inventor: TANI TAISHIN
IPC: F02M51/08
Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To provide a fuel injection nozzle capable of atomizing fuel spray, and injecting flow of atomized fuel to the specified direction. SOLUTION: Twelve injection ports formed in the disc part 25 of an injection port member, are divided into two groups of every six comprising injection ports 25a, 25b and 25c in two-by-two, so that each injection group is formed out of one atomizing flow 100. Injection ports 25a, 25b and 25c are so formed as to separate flow axis from one injection axis 110 as fuel goes toward the fuel injecting direction, so that the extension lines 111, 112 and 113 of the flow axes from the injection ports are separated from one another as they go toward the fuel injecting direction. Since fuel injected out of each injection port is formed into the atomizing flow 100 without scarcely collising mutually in the proceeding direction, the atomizing flow 100 is thereby uniformly atomized.  Since fuel sprays consisting of the atomizing flow 100 are mutually attracted with one another, the atomizing flow 100 is thereby advanced ahead in the specified direction without being scattered in the proceeding direction.
