Title: Optical code conversion method
Inventor: SOTOBAYASHI HIDEYUKI
IPC: H04B10/516
Filed: 2000-06-16
Abstract: PROBLEM TO BE SOLVED: To speedingly convert optical code of an optical pulse train without conducting optic/electric conversion and to simplify the constitution of the above conversion. SOLUTION: A first optical pulse train has a first wavelength λs and a phase which is modulated in a binary or multivalued manner and is added with a code. A second optical pulse train has a second wavelength λc and is added with control position information. The first and the second optical pulse trains are multiplexed and made incident on a nonlinear optical medium 17. As a result, a mutual phase modulation effect is generated between the trains, phase modulation is made to the first optical pulse train without making a wavelength shift and only optical code is converted.

Title: Explosion preventive method for parent die, and explosion avoiding method to increased die
Inventor: NAKAJIMA YASUJI
IPC: F42B39/22
Filed: 2000-06-20
Abstract: PROBLEM TO BE SOLVED: To prevent a parent die itself as a detonating body from exploding by placing at least a specified number of the parent dies in a container, and in addition, filling a gap between the container and the parent dies with a cushioning material and/or an insulating material at the times of carrying and maintenance. SOLUTION: In a carrying process and/or a maintenance process of a parent die 4, at least one piece of the parent die 4 is individually placed in a container 11. In addition, in a gap between the container 11 and the parent die 4, a cushioning material, e.g. waste, a linen bag and a fabric or the like, and/or an insulating material 12 such as a fabric are filled, and the parent die 4 is fixed in the container 11 by them. By this constitution, even if a carrier accidentally falls, the impact is transmitted to the parent die after being softened, and an explosion can be prevented from occurring. Also, at the time of an emergency, or at the time of carrying or maintenance under a thunder storm as well, the parent die 4 is being covered with the insulating material 12, and fear wherein the parent die explodes by an electric shock or an electric charging due to a thunder can be eliminated.
