Here’s a pending patent application with the World Intellectual Property Organization. The inventor is Michinobu Suzuki, working for a company called the Faith 21 Corporation. What, exactly, is this new product?
A musical instrument having a substance, which obtained by blending microparticles of a natural mineral such as graphite-silica emitting far-infrared radiation or minus ions with various coatings, applied and/or deposited in a definite part of the instrument body. Since this instrument can emit the far-infrared radiation or minus ions by itself or in the tone range thereof during musical performance, it can soothe the heart of the musician or listeners around her/him. At the same time, attempts are made to improve the physiological effects of the far-infrared radiation or minus ions on the human body to thereby enhance natural healing ability and preventive effects against diseases.
I should find a Japanese speaker to translate the full description, although I doubt it would make a whole lot more sense. In the meantime, somewhere out there, Scriabin is updating his Christmas list.
