Strong in durability and wear resistance, ideal for sewage pump stations and manhole pumps!

The 26KyX series water level gauge is a submersible water level gauge specially developed for sewage and wastewater applications. It features a diaphragm made of Kynar with PTFE properties, providing resistance to viscous media along with excellent hardness and abrasion resistance. The 26KyX water level gauge can be easily installed in harsh environments without the need for expensive protective cages that take up space. Measurement results can be obtained via an RS485 interface, as well as through analog signal output via a built-in D/A converter, allowing for scaling settings (modification of the water level range). A version with a built-in lightning protection device is also available (optional). 【Features】 - Anti-fouling diaphragm design - Body material made of SUS316L - RS485 serial communication - Accurate correction technology

The Hino Smart Cabinet provided by Nichinichi Shimizu Machinery Co., Ltd. is a material management solution that allows for the management of factory tools and consumables like a vending machine. This system automates inventory management and ordering processes, preventing the risk of production stoppages due to stockouts and significantly reducing the burden of inventory tasks. The cabinet comes in various types, such as drawer-type and spiral-type, allowing for the proper storage of drills, measuring instruments, protective gear, and more according to their intended use. Furthermore, the history management function through user authentication accurately tracks "who took out what and when," contributing to loss prevention and cost reduction. Operating 24/7 with no maintenance required, it is introduced as an efficient tool to promote the digital transformation (DX) of factories.

In civil engineering sites, there are many instances where temporary roads, access routes, heavy machinery work yards, and material storage areas use wooden boards. Until now, steel plates have been widely used, but their weight poses challenges in terms of transportation, installation, and removal. Hyper CLT boards are wooden civil engineering CLT materials that utilize timber. As temporary boards for civil engineering applications, they can be used for mud prevention, ground protection, and ensuring work pathways. The 5×10 board weighs about 230 kg, and the 5×20 board weighs about 460 kg, making them lightweight and easy to handle even with small machinery, which helps reduce the burden of on-site work and promotes labor savings. Additionally, as a material, it is easy to propose in terms of environmental considerations such as glare reduction, noise reduction, and CO2 fixation, thanks to the characteristics of wood. In public works, it can also be utilized as a material for creative ideas and safety measures. Hyper CLT boards are registered technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS "TH-250021-A." They are recommended for companies considering wooden boards, wooden temporary materials, civil engineering applications, and civil engineering CLT. We also accept consultations for implementation tailored to site conditions and requests for materials. Please consider them as an alternative to steel plates for public works and private civil engineering projects. We can also make proposals for sites inside and outside Okayama Prefecture. Feel free to contact us.

● The production time for cast 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 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! Different products, such as similar shapes or varying dimensions, can be molded at the same time in one molding process. This allows for the verification of multiple types in a short period.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding repair methods can cause changes in the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" and "secondary damage." Hinode Water Supply Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material with heat. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized.
