We have introduced 'design solar panel temporary enclosure lighting' at a construction site in Himeji City.

Brightly shining temporary enclosure signs can be installed without a power supply! They generate electricity with built-in solar panels and are illuminated at night.

★★★ Cordless LED Temporary Fence Sign "Design Solar Panel" ★★★ 【Basic Functions】 ● Features a structure with a solar panel built into the sign. ● Generates power independently by receiving sunlight. ● Uses stored electricity to illuminate LED lights at night. ● Enhances the visibility of the sign through lighting effects. 【Features】 1) No wiring required for installation - Completely eliminates the need for external power sources or wiring. - Contributes to reducing labor and costs associated with installation. 2) Simplified installation - All components are housed within the main unit in an "all-in-one structure." - Can be easily integrated into temporary fencing by simply incorporating the sign (For details on integration processing, please consult separately). 3) Easy maintenance - Maintenance involves replacing commercially available rechargeable AA batteries once every 5 to 6 years. - Allows for inexpensive and easy upkeep/management. 4) Display design - You can freely set the display content, including company logos, advertisements, safety notices, and artwork. 5) Utility model and patent obtained - Our company holds multiple intellectual property rights for the technology of integrating solar cells into signs.

● 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 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.

● 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.

We developed a system that expands the functions of the electronic manifest ASP "KENET" to record the traceability from waste to the creation of recycled resources using blockchain technology. In May 2025, as a pre-service, we implemented registration functions from waste registration to the input of the recycling process and the completion of recycled resources. In January 2026, we newly developed functions for inventory management and shipping of recycled materials. The system also includes a CFP registration function for recycled resources, allowing for data input on the decarbonization effects of resource circulation. We aim to utilize the waste management functions cultivated over 18 years with KENET to advance into the field of resource circulation and work towards the effective use of waste for a circular society.
