TOKYO, Japan - File photo shows mud hoppers in Ogi, Saga Prefecture, in June 2012. The population of mud hoppers in the Ariake Sea in southwestern Japan has shown an eight-fold increase in the first survey in 16 years, as they have been able to easily survive winters amid a temperature rise, a research institute said on May 29, 2013.

Futaba Corporation (Harima Town, Hyogo Prefecture) has developed a processing technology that can reduce the number of welding points from two to one on a square pyramid-shaped structure with a circular opening (photo). Rounded corner structures are used as ventilation fan ducts, hoppers, etc. By reducing the number of joints from two to one, the time and effort required for welding can be reduced, and the thermal degeneration of the material caused by welding can be minimized. In 2018, the company developed a press processing technology that can reduce the weld area of a circular structure with a circular opening to one side. This time, the company has applied the same processing method to round-cornered structures, making it possible to make welds on one side.
