[ZEROSAI Introduction Interview] Taisei Corporation: Significant Increase in User Numbers Through Integration of ZEROSAI and LINE WORKS - Utilizing Weather Information Has Become Standard.

The collaboration between ZEROSAI and LINE WORKS has significantly increased the number of users, making the utilization of weather information a common practice.

Issues - Even though ZEROSAI was introduced at the work facility, its usage was not widespread, with only about 10% of users being staff members. - We had to resolve basic issues such as the login method, and felt limited in our support. Implementation Points - By integrating with LINE WORKS, users naturally began to access ZEROSAI's weather information. - After our proposal for integration, we were able to quickly realize the connection with LINE WORKS. Implementation Results *For more details, please refer to the PDF document or feel free to contact us. *The attached photo is for illustration purposes.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm. Please feel free to contact us for more information!

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.

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 to the base material. Repairs can be carried out 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 you require a detailed technical explanation, please contact us.
