I invented CRSS (kro:s) technology to improve the sound quality of loudspeakers and developed CRSS speakers. All sound waves radiated inside the loudspeaker are 100% silenced by the CRSS structure. Therefore, the external radiation of sound waves is not interfered with at all from inside the loudspeaker, resulting in low distortion and extremely high sound quality.                                                                          Recent Niro Nakamichi

My high school was located on a hill facing the Sea of Japan Aomori Prefecture. There’s a fishing harbor　below and two lighthouses (red and blue, about 7 meters high) at the tops of two breakwaters. 　It was in this environment that I became interested in fluid dynamics and created a wind turbine generator. I built it with four telegraph poles (height 14m) and made a 5-meter-diameter, 5-blade wind turbine generator at the top. Ten car batteries were placed in the lower workroom. We created a device that converts the alternating current generated by the wind turbine generator into direct current and constantly charges the batteries. We turned on flashing blue lights from the top of the wind turbine generator toward the Sea of Japan at night. Fishing boats operating at night appreciated that they could see the blinking lights well even at a considerable distance,  and could better locate the harbor.
This was my first experience in developing this technology.
