In this document, we introduce case studies of the implementation of "iEL." At a major steel factory in Nagoya, product defects that were not visible with LED lighting have become much easier to see, resulting in zero complaints. Additionally, various reputable companies are continuously adopting this technology, including a major electronics manufacturer in Mito, a major printing machinery manufacturer in Tsukuba, and a major tire manufacturer in Fukuoka Prefecture. 【Implementing Companies】 ■ Comprehensive heavy machinery manufacturer Company I ■ Major steel manufacturer Company J ■ Major automobile manufacturer Company T ■ Major automobile dealer Company H ■ Comprehensive logistics trading company Company N *For more details, please refer to the PDF document or feel free to contact us.

The "iEL" has no glare or dazzling brightness. It eliminates the diffuse reflection (making surfaces appear blurry) that occurs on object surfaces depending on the angle of illumination, making it easier to check for fine scratches and unevenness. It is an essential condition for inspection and quality control tasks, as it does not create strong shadows at hand or foot level, making it suitable for spaces such as factories, warehouses, and sports facilities. 【Features】 ■ Bright yet not dazzling ■ High-quality light that suppresses diffuse reflection, making small scratches easy to see ■ Prevents oversight, avoids potential dangers, and improves work efficiency ■ Significant energy savings and high color rendering are excellent ■ The way objects appear is crucial ■ The light is soft and suitable for the work environment *For more details, please refer to the PDF materials or feel free to contact us.

Just attach it to your regular helmet! Compatible with helmets from various manufacturers! The "Pro Specification" helmet air conditioning fan "My Fan Plus Helmet Attachment Kit" provides powerful airflow to the back of the head and neck. ● Compatible with helmets from various manufacturers Cooling the back of the neck (cervical area) is considered effective for preventing heatstroke. This product, developed as a fan that can be attached to your existing helmet, is a cost-effective heat prevention solution that enhances the heat countermeasures for each worker at job sites in the blazing sun. Despite its small size, it can deliver strong airflow, effectively reducing the temperature rise at the back of the neck during outdoor activities. It can be securely fixed to the helmet with dedicated bands and clips, ensuring safety as well. It is designed for heat countermeasures for field workers and others. Please also check out the video demonstrating the visualization of airflow. In March of this year, the Ministry of Health, Labour and Welfare announced the "STOP! Heatstroke Cool Work Campaign," urging all businesses to thoroughly implement heatstroke prevention measures in the workplace, and began recommending the use of "fan-equipped helmets," which has led to a significant response. ↓↓↓↓↓↓↓↓ The Ministry of Health, Labour and Welfare recommends wearing fan-equipped helmets ↓↓↓↓↓↓↓↓

[Safe and secure neutral disinfectant (surfactant) developed with cosmetic ingredients] "Glycine" is a component found in natural scallops and shrimp, and is commonly used in shampoos and lotions. A major domestic cosmetic ingredient manufacturer has successfully developed glycine with excellent penetration and disinfecting power through its unique technology. It possesses outstanding penetration and disinfection capabilities, making it effective for cleaning dirt, disinfecting, and preventing mold. Due to its high disinfecting effect, glycine is also used as a disinfectant for surgical instruments and as an infection prevention agent. [About the novel coronavirus] According to experts, even without alcohol disinfectants, the "surfactants" found in "soap" or "household neutral detergents" can be effective. The "novel coronavirus" is very similar to the "SARS virus" and both share a common "envelope," which is a "lipid membrane." Alcohol destroys this "envelope," eliminating the virus's infectivity, but the National Institute of Infectious Diseases has announced that the same effect has been confirmed for the "SARS virus" using "surfactants." Although this has not yet been confirmed through experiments for the current "novel coronavirus," similar effects are expected. (Refer to NHK Asahi's website)

**The End of Mercury Lamps** The Minamata Convention on Mercury is... An international conference held in Japan in the fall of 2013. ● Currently, the use of mercury lamps worldwide has been decided to be banned for manufacturing and import/export after 2020 due to the conclusion of the Minamata Convention. The convention establishes comprehensive regulations to reduce the risks that mercury poses to human health and the environment. ● In Japan, the manufacturing of products using mercury has been generally prohibited since 2017.
