We will be exhibiting at the Hokkaido Urban Development and Construction Comprehensive Exhibition 2021 from October 27 (Wednesday) to 28 (Thursday), 2021.

Comparison with typical water supply pipe deterioration countermeasures! We introduce the duration of effectiveness and issues.

The "Piping Magnetite Method" involves installing BW in the water supply pipes, which slows down the oxidation rate, transforming red rust into black rust and repairing the deteriorated areas. This method is also applicable to leaking pipes and has a semi-permanent effect. The "Piping Replacement Work" provides an immediate and fundamental solution as the pipes become brand new, but it is very costly and generates a large amount of waste. The "Lining Method" damages the pipes, making a second application impossible. The "Magnetic Device Installation" has issues such as being ineffective at low flow rates. We also offer materials that cover all these topics. 【Features of the Piping Magnetite Method】 ■ Low cost and short construction period ■ Effects extend to drainage pipes ■ Improved cleaning power, antioxidant power, and antibacterial power ■ Effect measurement device allows for FS *For more details, please refer to the PDF materials or feel free to contact us. *The section "Trigger for Interest" displayed during the PDF download is generated by the AI of Ipros Co., Ltd.

By installing a water conditioning device, the red rust in the pipes changes to black rust, restoring the thickness of the degraded pipes!

The "Piping Magnetite Method" uses the water quality improvement device "The Bio Water" to convert red rust in water supply pipes into black rust (ferric oxide), aiming to extend the lifespan of the piping. The modified water forms a dense and continuous coating of calcium carbonate and other substances inside the pipes. As the red rust transforms into black rust, it repairs and restores the corroded areas of the deteriorated piping. Improvements in the blockage rate of the piping, as well as the prevention of leaks and red water occurrence, can be achieved at low cost and in a short construction period. Depending on the hardness, it is generally maintenance-free, thus reducing maintenance costs and efforts. 【Features】 ■ NETIS registration [KT-160125-A] ■ Installation involves simple construction at the water supply pipe's origin, with a short construction period of about half a day to one day ■ There is no need to replace pipes, allowing for low-cost measures against red rust ■ The effects are semi-permanent, enabling the use of water supply pipes for the lifespan of the building ■ Reduces BOD in wastewater, thereby lessening the environmental burden on water *From the download link below, you can view materials introducing the "Piping Magnetite Method" and the product catalog for "The Bio Water" all together. *The section titled "Trigger for Interest" displayed during the PDF download is generated by the AI of Ipros Co., Ltd.

Recommended for those who: Feel challenges in safety management and weather management at sites without radio signals or power supply. Have concerns about operating observation equipment at remote sites such as islands or mountainous areas. Have postponed the idea of weather DX at their sites, thinking "it's impossible for us." Content of the day (4 chapters / approximately 30 minutes): Why is weather countermeasure necessary now at sites without signals or power supply? (Background) [Understanding] Weather risks lurking in sites without radio signals or power supply. [Preparation] The three pillars of observation, forecasting, and notification, along with securing power and communication. [Practice] Implementation methods and case studies - operations using satellite communication and solar power, nationwide support made possible by Sysmet, and monitoring equipment operation. Chapters 1 to 3 will provide common "learning" for the sites, while Chapter 4 will introduce "how to actually do it" with specific case studies. Event Overview: Date: August 28 (Friday) 11:00 AM - 11:30 AM Format: Online (Zoom) Participation Fee: Free Chapters 1 to 3 will provide common "learning" for the sites, while Chapter 4 will introduce "how to actually do it" with specific case studies.

Are you facing challenges with managing, reviewing, and checking paper drawings? Based on case studies from the manufacturing industry, we will demonstrate practical methods for digital checking using LCD pen tablets and PDF handwriting software. We will explain the key points for streamlining operations while reducing printing, circulation, and scanning tasks, and maintaining the quality of checks. ■ Date and Time: September 2, 2026 (Wednesday) 13:00 - 14:00 ■ Webinar Content 1. Why is DX in checking required now? - Challenges of checking tasks using paper drawings - Environmental changes surrounding the design department 2. Introduction of case studies on digital checking in the manufacturing industry 3. Introduction of features usable on-site, such as redlining on PDF drawings, pen input, and multi-touch operations, among others Viewing instructions will be sent to the registered email address after completing the application. 【Target Audience】 - Those considering paperless drawings - Those who want to improve the efficiency of checking tasks - Those feeling challenges with printing, storing, and transporting paper drawings - Those who want to make telework and communication between sites smoother - Those who want to digitize handwritten tasks directly - Those who want to promote both paperless operations and business efficiency simultaneously

"Even though we've introduced AI, we're only using it for creating meeting minutes and proofreading... We want to be more efficient." For those who feel this way, we will introduce the possibilities of utilizing AI in combination with kintone data, along with specific examples by business type!
