The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

From July 15 (Tuesday) to July 20 (Sunday), 2025, the "42nd Daihatsu Japan Open 2025 Badminton Championships" was held at the Tokyo Metropolitan Gymnasium. We would like to report on the motion capture experience session conducted by Yonex Co., Ltd. at the venue. During the experience session, participants were asked to swing three different types of rackets from different generations, focusing on whether there were differences in their top speeds. The measurement was conducted using the same Raptor-12HS system utilized at the Yonex Performance Innovation Center (Blue Lab). This was a valuable opportunity to experience the research equipment that is not currently open to the public and to see what kind of measurements are being conducted! ---[Yonex Co., Ltd.

Hello, this is the public relations department of KAITAKU Co., Ltd. in Okayama City, Okayama Prefecture! Recently, our wooden lightweight hyper CLT sheet has been officially registered with the Ministry of Land, Infrastructure, Transport and Tourism (NETIS number: TH-250021-A). The decisive difference between hyper CLT sheets and conventional temporary materials lies in the "exit" after their durability period ends. The hyper CLT sheet (NETIS number: TH-250021-A) is not discarded after its role on site is finished; instead, it is reused as chip fuel for biomass power generation. • Made: It is made from **wood (thinned timber)**, resulting in low environmental impact. • Used: It significantly contributes to reducing CO2 on site. • Converted to energy: Once its durability period is over, it becomes chip fuel for biomass power generation, ensuring that no resources are wasted. In this way, a **"complete circular" system** is established that connects materials to energy. Additionally, these initiatives can serve as a strong appeal for creativity related to construction performance. Please try the hyper CLT sheet (NETIS number: TH-250021-A)!
