We will exhibit at the 10th International Drone Exhibition! (Tokyo Big Sight)

[Inspection Support Technology Performance Catalog] Introducing inspection technologies for structures utilizing drones, pole cameras, and AI image analysis technology.

We would like to introduce a technology that supports structural inspections consisting of "non-GNSS environment compatible drones," "pole cameras," and "image analysis software for extracting damage." *Technical overview materials are available in the catalog section at the bottom of this page. Additionally, this document has been created for those who have downloaded it to provide an overall understanding of our company's technology. Since detailed information is not included, please contact us through the inquiry section of this page or the email address listed at the end of the presentation materials if you require specific explanations. *It is also possible to conduct individual briefing sessions using web conferencing systems.

• Image analysis software

A inspection robot that can automatically avoid obstacles such as eaves and windows to ensure worker safety and address labor shortages! It is also capable of close visual inspection using cameras and detecting floating issues with a tapping device.

This is a robot developed through joint research between Toyohashi University of Technology and Sanshin Kenzai Kogyo, designed to ascend and descend exterior walls for inspections. The development concept focuses on ensuring the safety of workers, addressing labor shortages, digitizing inspections and surveys, and securing flexibility in application through modularization. Currently, we are conducting verification tests with the aim of commercialization. 【Development Concept】 ■ Ensuring the safety of workers ■ Addressing labor shortages ■ Reducing costs of inspections and surveys ■ Securing flexibility through modularization of inspection equipment 【Benefits of Implementation】 ■ Capable of carrying inspection equipment and using cameras and impact testers to diagnose deterioration and detachment of exterior walls ■ Enables high-altitude inspections without the use of scaffolding or gondolas ■ Eliminates concerns about dangerous work, costs, stress, and aesthetics ■ Allows for inspections of bridge decks without the use of crane trucks on bridge roads *This robot is currently under joint research and development.

No differences in sensory perception among individuals! Development of a "floating" inspection method as a substitute for sound inspection.

At Sanxin Building Materials Industry Co., Ltd., we aim to provide accurate inspections that yield consistent results, regardless of who conducts them, for investigations of "floating" in structures (mortar) and precise inspections after "floating" repairs. Using a method called "V-transmission," we propagate ultrasonic waves into the structure, detecting delamination (voids) inside the structure from the waveforms of the reflected ultrasonic waves. Since ultrasonic waves can be emitted and propagated through the air, there is no need for a contact medium. 【Features】 ■ Inspection results can be saved as data ■ No differences due to human perception ■ Ultrasonic waves can be emitted and propagated through the air ■ No need for a contact medium *For more details, please refer to the PDF document or feel free to contact us.

• Visual Inspection Equipment

Introduction of various surveys and proposals utilizing infrared cameras, radar rebar detection, and various tests.

At Sanxin Building Materials Industry Co., Ltd., we conduct investigations that include thermal photographs of exterior walls as visual aids for exterior wall inspections. By using infrared images in addition to traditional inspections, we can appeal visually to clients, leading to a deeper understanding. In the inspection of concrete structures, we utilize the radar rebar detector "SIR-EZ," which combines a control computer and detection device into one, allowing for quick detection of rebar and non-metallic pipes within the structure. A laser pointer is used to indicate the location of the area currently being surveyed and the position of embedded objects such as rebar from the front and side of the detection device. We provide a speedy rebar survey without careless mistakes. 【Features】 ■ Ability to appeal visually by using infrared images ■ Quick detection of rebar and non-metallic pipes within concrete structures ■ Significant improvement in work efficiency by using equipment equipped with a laser pointer ■ Various investigations including core sampling, compressive strength testing, carbonation testing, and report preparation *For more details, please refer to the PDF document or feel free to contact us.

● The production time for casting 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 creating 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 variations in dimensions, can be created in a single molding process. 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 affecting the base material with heat. Repairs can be carried out 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.

Dear Sir/Madam, I would like to express my congratulations on the continued prosperity of your company. Thank you very much for your exceptional support. We would like to inform you that our company will be closed for winter holidays during the following period. We apologize for any inconvenience this may cause and kindly ask for your understanding. 1. Winter Holiday Period From Thursday, December 28, 2023, to Thursday, January 4, 2024. 2. Business Operations After the Winter Holiday Period We will resume normal operations from Friday, January 5, 2024.

● 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. Please feel free to contact us for more information!

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.
