Completion of the Hexa Gate Plug Construction for the Tachiaigawa Main Line Water Stop Wall.

Post-installation water shut-off confirmation is possible! The manhole structure features an easy-to-open and close pin insertion mechanism operated by a handle.

We would like to introduce our "Hexagate Plug." It allows for water stop confirmation after installation. It features an easy-to-open and close manhole structure with a pin insertion mechanism operated by a handle. It can be used for temporary storage of rainwater main lines in shield tunnels, as well as for safety measures during branch connection work and backflow prevention during heavy rainfall. 【Features】 ■ High water stop sealing mechanism ■ Water stop confirmation possible after installation ■ Easy-to-open and close manhole structure ■ Manhole water stop mechanism *For more details, please refer to the PDF document or feel free to contact us.

A closing plug that excels in lightweight, airtightness, and durability, and is active in a wide range of fields!

This product is a closing plug used for blocking the openings of various pipelines. It is utilized in various fields to prevent the intrusion of foreign objects during plumbing work and to prevent the leakage of liquids and gases from the pipelines. Due to its simple and lightweight design, it offers excellent workability and can be quickly attached and detached as needed, greatly contributing to the reduction of labor hours. This product effectively expands the opening by sandwiching a rubber ring with a C-shaped cross-section between two inclined iron plates. 【Features】 ■ Easy operation without tools ■ Cost-effective with rubber ring replacement *For more details, please refer to the catalog or feel free to contact us.

Can seal large gaps! Pressure management allows for adjustment of sealing surface pressure.

The "TUBE SEAL" expands (inflatable) by being pressurized with a fluid (air, water, oil, etc.), sealing gaps and demonstrating its sealing function. It can seal large gaps and can follow the irregularities, distortions, misalignments, and vibrations of the sealing surface. Additionally, it allows for pressure management and on/off adjustments via remote control, and the sealing surface pressure can be adjusted through pressure management. 【Features】 ■ Capable of sealing large gaps ■ Can follow the irregularities, distortions, misalignments, and vibrations of the sealing surface ■ Allows for pressure management and on/off adjustments via remote control ■ Sealing surface pressure can be adjusted through pressure management ■ Specifications can be designed separately according to application *For more details, please refer to the PDF document or feel free to contact us.

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 on the base material. 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.

● 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.

Are you struggling to explain "safety" to the client using just drawings? - The risks in blind spots are difficult to convey to the client through drawings alone. - Safety measures often become a target for cost reduction, making it hard to communicate their necessity. - There is a concern that the client might say, "It's more dangerous than I thought," after completion. Risks that are visible to design professionals are not easily understood intuitively by clients who are outside the field. This document is not just a simple explanation of sensor functions; it is a guide to visually explain "why sensors are necessary in that location." It can be used directly as explanatory material for the client. Here are three key points for utilizing this document: 1. Visualization of Risks Blind spots during vehicle departure and contact risks within the site are illustrated clearly. 2. Clarification of Selection Criteria A comparison table outlines the differences between complex sensor types such as infrared, ultrasonic, and loop coils. 3. Diagram of System Configuration It illustrates not just the sensors alone, but how they combine with components like rotating lights and control panels, providing practical assistance for electrical equipment design. Please make use of this to prevent "rework after completion" and "accident risks."

In facilities operating nurse call systems, we have made the bed exit sensor wireless, allowing it to notify in conjunction with the nurse call system. By simply connecting the mat sensor "Foldable Thin Matt-kun," the body movement call "Ugo-kun," and the wheelchair body movement call "Ayumi-chan" to the transmitter HB-RS, you can make the bed exit sensor wireless. The infrared sensor "Just Place Pole-kun" has the transmitter HB-RS built-in. This helps prevent accidents caused by falls, slips, or wandering, contributing to the efficiency of medical operations. 【Features】 ○ Wireless conversion by simply connecting existing sensors to the transmitter HB-WSK. ○ The bed exit sensor notifies wirelessly in conjunction with the nurse call system. ○ Up to 5 transmitters can be registered with a single receiver. ○ The communication distance between the transmitter and receiver is approximately 10 meters. ◎ For more details, please contact us or download the catalog.
