Prove Mind Inc. (Headquarters: 1-3-6 Hirakawacho, Chiyoda-ku, Tokyo; CEO: Satoshi Yuza) will begin offering a new design environment called "TAYURA Canvas" for its self-developed business infrastructure service "TAYURA Base" starting in early October 2025. TAYURA Canvas is built on the open-source design tool "Penpot" and is characterized by its ability to be used on dedicated company servers rather than as a public cloud service. This allows for secure collaboration with reduced risk of information leakage while sharing designs among internal and external teams. Additionally, we will provide a stable environment and support to ensure that the open-source software can be utilized in a manner suitable for corporate use.

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.
