You can estimate the required number of units and brightness with your computer! Would you like to save time on lighting design?

The simple lighting calculation software "STAR LIGHTER" from Hoshi and Denki allows for easy lighting design. Additionally, it can calculate the number of fixtures and average illuminance for new installations or updates. It enables various lighting calculations for both indoor and outdoor settings, and it can also create illuminance distribution maps for a single lamp, thus improving operational efficiency compared to traditional methods. Please give it a try. 【Features】 - Capable of calculating the number of fixtures for indoor use - Easy creation of illuminance distribution maps - Conducts illuminance calculations for outdoor settings and creates horizontal illuminance distribution maps *For more details, please contact us or refer to the catalog. -------------------------------------------------------- You can also download it from our website.

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.

● The production time for cast prototypes can be shortened! Since model making is not required, the production time for 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! Different products, such as similar shapes or varying dimensions, can be molded at the same time in one molding process. This allows for the verification of multiple types in a short period.

Last month, we held a spring safety conference hosted by our company. We have compiled the details and atmosphere of the day into a PDF. We would appreciate it if you could take a moment to read it.
