We have published a FAQ for the waterproof sleeve "Pipe-in-Sleeve" for underground and outer wall use.

[Official Release] Waterproof Sleeve for Underground Walls "Pipe-in-Sleeve" (Abbreviated as PIS) Reducing Labor at Construction Sites! Enhancing Waterproof Performance of Buildings!

■Recently, our "Pipe-in-Sleeve," showcased at the JECA Fair 2025, is officially released with great anticipation.■ In the underground wall section (underground beam sleeve), we have pre-treated the PVC sleeve and the outer space (gap) of the FEP with "waterproof treatment" at the factory, making it prefabricated for the site. On-site, there is no need for cumbersome work; after installing the PIS, basically only joint connections are required. It ensures stable waterproofing! Achieving work efficiency and promoting flood prevention and water resistance. This is an innovative and advanced product for underground beam sleeve construction. <Features> ■ Excellent waterproof performance [Flood prevention and water resistance promotion] ■ Proposal for labor-saving at construction sites ■ Adaptable to individual project design specifications ■ Improved work efficiency, standardized quality, and enhanced maintainability [To Designers and Contractors] FEP pipe through-piping, bell mouth terminal installation, connection of different pipes (AQ type), and various connection parts of Eflex can be arranged according to the specifications of each construction site! Furthermore, it can also respond to unexpected water leaks! It combines maintenance and serviceability, making it a versatile and highly adaptable product. (Feel free to request drawings as well)

Streamlining on-site work through prefabrication! Additionally, improving the waterproof performance of buildings.

In the construction industry, there is always a demand for shorter construction periods and improved quality. In particular, the waterproofing treatment of the underground beam exterior wall is the most critical construction area for eliminating leakage risks and enhancing the safety of the building's power supply. Traditional methods often require complex waterproofing work on-site, leading to longer construction periods. However, the Pipe-in-Sleeve (PIS) system simplifies on-site work by prefabricating PVC sleeves and FEP pipes in the factory, contributing to shorter construction times. [Usage Scenarios] * Underground beam/exterior wall penetration * Underground penetration/power cable entry [Benefits of Implementation] * Labor-saving (reducing the burden on workers) * Shorter construction periods * Improved waterproof performance [For Designers and Contractors] FEP pull-through, bell mouth terminal installation, etc., can be customized to individual site specifications! Additionally, it can handle unexpected leaks! It is a versatile and highly adaptable product that also incorporates maintenance and serviceability. ● Be sure to check out the introduction video on YouTube, "Tome Taro Channel." * For more details, please request a catalog from "Contact Us," or view the PDF data from "Download."

Efficiently streamline on-site work with prefabrication! Achieve shorter construction periods and improved quality.

[Coming Soon] An upgraded version of the beloved "Pipe-in-Sleeve"! "Pipe-in-Sleeve T-Type," abbreviated as PIS-T. In contrast to the PVC sleeve, a through pipe made of FEP has been pre-filled with waterproof material (sealant) at the factory, making it prefabricated. The T-type further features a "drainage PVC flange" welded with PVC material to the outer layer of the PVC sleeve. This method replaces the ring-shaped or band-shaped waterproof material on the outer circumference of the PVC sleeve, responding to strong requests from construction companies. <Features> ■ Excellent waterproofing due to prefabrication: Promotes flood prevention and water resistance ■ Labor-saving at construction sites! Reduces worker burden and prevents troubles in advance! ■ No skilled techniques required! Simplifies complex tasks! ■ Flexibility to accommodate individual design specifications of projects! ■ Improved work efficiency, standardized quality, and enhanced maintenance!

Nitto Kousakusho Co., Ltd. (Osaka) is a comprehensive manufacturing company that supports production through "jig expertise × precision machining." We will introduce the concept of "jigs," which is the foundation of our company, in several installments. When our representative, Saraya, speaks at lectures and technical seminars about machining, jigs and dedicated machines, and rotary engine (RE) development, he always touches upon "jigs." This concept has been passed down since the time of our founder, Isamu Saraya, and is the origin of our machining practices. Our particular strength has been in the design and production of holding jigs for machining. The know-how in jig design and manufacturing cultivated over many years in the field has been applied to precision machining, the design and production of dedicated machines, and even RE development. We define jigs as "auxiliary tools that fix the workpiece in the correct position during processing or assembly and guide the work." Based on this concept, we have focused on the impact of jig innovations on machining accuracy and work efficiency in our manufacturing efforts. In future installments, we will continue to introduce Nitto Kousakusho's manufacturing philosophy, incorporating examples.

Nitto Kogyo Co., Ltd. (Osaka) is a comprehensive manufacturing company that supports production through "jig expertise × precision machining." [Reasons Why Jigs Are Necessary | Limitations of Manual Work and Variability in Quality] In the previous discussion, we introduced the basic definition of "what a jig is." This time, we will explain the background of the necessity for jigs, focusing on the "limitations of manual work," using relatable examples. ☆ When Undertaking the Job of Sharpening Pencils At our company, we explain the concept of "jigs" in an easily understandable manner using familiar examples during lectures and presentations. For instance, let's say we take on the job of sharpening pencils from a certain company. If we do this manually with a knife, there will be variability in the angle of sharpening, the length of the lead, and the finished shape, depending on the worker. There will also be differences in working time, leading to challenges in achieving uniform quality and production efficiency. To stabilize "work that is influenced by human skill," jigs are necessary. By using jigs, anyone can process at the same position and angle, enabling stable manufacturing with reduced variability in quality. Our company utilizes this concept of jig creation to engage in precision machining, prototype production, and the design and manufacturing of specialized machines. To be continued.

The "JECA Fair 2026 74th Electrical Industry Exhibition" will be held soon from May 27 (Wednesday) to May 29 (Friday) at Tokyo Big Sight. We are planning to showcase at the booth of Furukawa Electric Co., Ltd. "Waterproof Sleeve for Underground Outer Walls - Pipe in Sleeve" We have compiled the inquiries we received regarding the product launch and have created an FAQ, which we have started to publish. Since last year's JECA Fair, we have received numerous inquiries and requests from various fields, for which we are truly grateful. We kindly ask you to take a look. Thank you.

The facility operating the nurse call system has made the bed exit sensor wireless, allowing it to notify in conjunction with the nurse call. 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. 【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. ○ Up to 5 transmitters can be registered with one receiver. ○ The communication distance between the transmitter and receiver is approximately 10 meters. ◎ For more details, please contact us or download the catalog.

We will introduce the implementation results of the sensor technology developed by the Hotron Group, which has been cultivated over more than half a century, through customer case studies. In addition to automatic door sensors, we also offer a wide range of vehicle detection sensors and nursing/care sensors. We have many implementation examples available, so please take a look at the case study page.
