As you know, the big bang that took place so long ago created our uni-verse, in which the earth was later created and then mankind. In compar-ison to the tens of billions year-old space, man's life in the earth is about 80 years at best. For man, our planet is like a station that we stop by for very short time. Under this circumstance, I as a human being want to leave something meaningful or valuable to the next generation. So I determined to com-mercialize 3 patented inventions whose intellectual property rights belong to me and that I consider most priceless. In association, I founded a cor-poration which has been actively doing business with those inventions. More specifically,'Welding Coupler' Currently, we are witnessing the outbreaks of earthquakes around the firering of pan-Pacific region, which are more and stronger than before. By the way, apartments and other buildings in major cities are more and more skyrocketing in the aftermath of spikes in land prices. Nevertheless, such constructions are still being made using conventional rebar couplers that are never earthquake-resistant, leading to concerns over the possible loss or damage of human lives. This is the very reason why I started busi-ness with a sense of duty as a human existence for the purpose of pro-tecting mankind.
