Title: Method of heat-treatment for high carbon steel rail
Inventor: UEDA MASAHARU
IPC: C21D9/04
Filed: 2003-01-24
Abstract: <P>PROBLEM TO BE SOLVED: To provide a rail in which the generation of pro-eutectoid cementite in a rail columnar part, further, a head part and a foot part, is restrained and the development of brittle fracture and the lowering of fatigue strength and toughness, is prevented and the wear resistance of the rail head part is secured in a high carbon steel rail.  <P>SOLUTION: In the steel rail containing 0.90-1.20 mass% C, after hot-rolling into the rail-shape, the foot tip part of the rail is acceleratively cooled to at least 650°C at 5-20°C/sec cooling velocity from the austenite (γ) zone temperature within 60 sec, and/or the columnar part is acceleratively cooled to at least 650°C at 2-20°C/sec cooling velocity from the γ zone temperature within 100 sec. As the other way, within 60 sec after hot-rolling into the rail-shape, the temperature at the foot tip part is elevated by 50-100°C from the temperature before the temperature rise and/or within 150 sec, the temperature of the columnar part is elevated by 20-100°C from the temperature before the temperature rise. Then, the head part and the foot part are acceleratively cooled to at least 650°C at 1-10°C/sec cooling velocity from the γ zone temperature.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Title: Pseudo random number generating device
Inventor: HAMANO JUNJI
IPC: G06F7/58
Filed: 2003-01-24
Abstract: <P>PROBLEM TO BE SOLVED: To further prevent leakage of information to a third party.  <P>SOLUTION: A pseudo random number D1 is generated by using a result derived on the basis of prescribed information used in a prescribed communication protocol as seeds, and a partial random number D3 or a hash value D4 is generated by changing the state of a random number sequence in the pseudo random number D1 by providing the pseudo random number D1 with a signal processing to reduce the information amount of the pseudo random number D1. Consequently, even when the partial random number D3 (or the hash value D4) is illegally obtained during transmission, it is possible to prevent the third party from guessing the pseudo random number D1 which is the generating source of the same without allowing the third party to find the pseudo random number D1 on the basis of the partial random number D3 (or the hash value D4). In this way, leakage of information to the third party can be further prevented.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
