Notice of Participation in the Construction Technology Exhibition from October 23 (Wednesday) to October 24 (Thursday), 2019.

High water resistance! Reduced lifecycle costs through partial replacement with a bolt fastening structure!

The "Hinoductile Joint α (for road use, general regional type)" is a cast iron expansion device that excels in replaceability, durability, and running safety. By bolting the main body of the expansion device to the slab, it allows for partial replacement of only the main body during the next replacement, enabling the reuse of the foundation mortar and reducing the life cycle cost (LCC)! Additionally, made from Hinoductile cast iron, which possesses strength and elongation, it features an optimized structure that enhances durability. The surface layer incorporates a textured structure similar to the ASD (Anti-Slipping-Design®) developed for manhole covers, providing slip resistance that lasts for an extended period, equivalent to or better than wet asphalt. 【Features】 ■ Reduced life cycle costs through partial replacement with a bolted structure ■ Achieves durability equivalent to 30 years through unique cast iron technology ■ Load-bearing plates and dust-proof materials ■ Semi-circular shape mitigates impacts during vehicle passage ■ Applies slip-resistant structure developed for manhole covers ■ Protection of waterproofing materials with minimal changes in slip resistance values ■ High waterproofing at connection surfaces *For more details, please refer to the PDF document or feel free to contact us.

Cast iron expansion device that can be installed within a pavement thickness of 75mm with a box depth! 【NETIS registered product】 Space-saving installation series.

The "Hinodakutairu Joint α SCV Type" is a cast iron expansion device for bridges that achieves a durability equivalent to 30 years through unique casting technology. It is a steel load-bearing type that can be installed within the pavement thickness (cut depth of 75mm) without removing the existing deck slab. It is suitable for installation on small to medium-sized bridges with thin deck slabs, which could only be addressed by conventional materials or butt-type rubber joints. A packing integrated with a water-stopping material is placed on the connection surface of the main body to prevent leakage at the connection. Additionally, it adopts a slip-resistant pattern that has proven effective in manhole covers. The surface of the box-out section is finished with a Doro Guard, preventing exposed concrete from being visible and maintaining minimal changes in slip resistance values while also excelling in aesthetics. 【Features】 ■ Can be installed within the pavement thickness (box-out depth of 75mm) ■ No need for special equipment arrangements ■ Achieves a durability equivalent to 30 years through unique casting technology (based on our test results) ■ Protection of the water-stopping material with a load-bearing plate and dust-proof material ■ High water-stopping capability at the connection surface ■ NETIS registered product (QS-210051-A: Space-saving installation compatible expansion device) *For more details, please refer to the PDF materials or feel free to contact us.

On November 20, 2025 (Thursday) and December 2, 2025 (Tuesday) from 11:00 to 14:00, our representative, certified public accountant and tax accountant Koichi Yokoyama, will be speaking at a free webinar hosted by Otsuka Shokai. He will explain important points to note regarding the revised Construction Business Act. [Construction Business Act / Public Works Optimization Promotion Act] - Prevention of omissions in the description of construction contracts - Obligation to notify "risk" information before contract signing by the contractor - Mutual exchange of original copies of construction contracts - Digitization of estimates, contracts, and order forms/acceptance letters We are entering an era where contracts must be documented in writing and stored electronically. Paperlogic is fully committed to supporting companies that have begun the transition from paper to digital.

Fujikohsuhou Co., Ltd. will hold a free online seminar titled "Laser Hardening Data by Material Type" on Wednesday, November 19, 2025. There are various materials that are easy or difficult to harden in laser hardening. We provide a simple explanation of the reasons behind this. This seminar will be a useful reference for design engineers considering laser hardening during the design phase. 【Recommended for】 ■ Those who want to know about materials commonly used in laser hardening ■ Those who want to understand the hardening characteristics of various materials

"We want to improve our operations with AI, but what exactly can we do...?" For those who want to actually try out and compare services, we have an announcement. The electronic contract and document management service paperlogic will be exhibiting at the 'Business Innovation Fair 2025 Autumn in Makuhari' hosted by Otsuka Shokai on November 13th (Thursday) and 14th (Friday) at the Hotel Green Tower Makuhari. Seminars on business improvement and AI utilization will also be held, so if you are nearby, please come and visit us. ● We will also be conducting product demonstrations of paperlogic at the venue. The biggest feature of paperlogic is that it is easy to operate and simple, yet it complies with all document management regulations, including the Electronic Books Act. We invite you to experience this simplicity firsthand.

1. "A New Era of Disaster Prevention and Mitigation Opened by Satellite Remote Sensing" Satellite remote sensing is a technology that uses sensors mounted on artificial satellites to acquire information about the Earth's surface over a wide area. In this presentation, we will outline the basic mechanisms and characteristics of remote sensing and introduce specific case studies of its application in the field of disaster prevention and mitigation. Furthermore, through examples of the latest satellite data applications, we will discuss future technological prospects and social possibilities.
