n 3D laminated molding, tubular structures cannot be put to practical use unless the resin powder left behind in the internal microstructure and tightly packed can be removed. Even if a scanty structure can be created from the outside, a complex piping structure cannot be commercialized. Bluestar R&D’s ultrasonic waves penetrate the pipe walls of…続きを読む
Ultrasound is used to generate countless vacuum balls (cavities) of 10 mm in diameter in water. 20,000 times per second or more, these vacuum balls are generated and annihilated in 1/40,000th of a second. At that time, positive and negative shock waves are generated. In water, a vacuum ball of 10 mm in diameter is…続きを読む
AM metal printers and metal 3D laminated molding technology are spreading rapidly for aircraft parts, military parts, space equipment, and more. Miniaturization of parts, integration of many parts. Designs are complex and now often human- and AI-driven. More complex, and the ultimate miniaturization is also the goal. There are problems. The smaller and more complex…続きを読む
Hyaluronic acid is a superorganic macromolecule with a molecular structure of more than 2 to 3 million. Hyaluronic acid is a superorganic macromolecule with a molecular structure of 2 to 3 million or more. Hyaluronic acid can moisturize the skin, but because it is a high molecular weight, it does not penetrate subcutaneously. Therefore, it…続きを読む
Lignocellulose (cellulose, hemicellulose, and lignin), the main component of plant cell walls, is broken down and cellulose is separated using powerful ultrasound. When cellulose is mixed with ethanol yeast and fermented, bioethanol is produced. All plants are raw materials for biofuels. Furthermore, ultrasonic waves can be applied to cellulose to produce nanocellulose and nanocellulose fiber.…続きを読む
The undercarriages of Shinkansen and other train cars also need to be disassembled and maintained after the legal period has passed. In order to perform maintenance, equipment that has been used in a harsh environment must be disassembled and cleaned. The problem is that the dirt is not deposited in an environment that is overwhelmingly…続きを読む
