Aiming for low loss, accurately measure the actual state of electromagnetic materials and grasp and analyze their vector magnetic characteristics!

Iron loss evaluation, which has been a bottleneck in motor analysis. Conventional methods only consider iron loss as a function of magnetic flux density, resulting in low accuracy. However, accurately determining the magnetic field and magnetic flux density to calculate iron loss is achieved through "vector magnetic characteristic analysis." This allows for the calculation of high-precision distributions of magnetic fields, magnetic flux densities, and iron losses that are not achievable with other software. Vector magnetic characteristics refer to the properties that take into account the relationship between the magnetic field H and magnetic flux density B of electromagnetic steel materials, considering their direction (vector). The finite element method electromagnetic field simulator that incorporates this characteristic is “μ-E&S.” 【Features】 - High-precision calculation of magnetic field vectors is possible by considering vector magnetic characteristics. - Rotating magnetic fields and hysteresis can be calculated. - It is designed as an easy-to-use tool specifically for iron loss evaluation. *For more details, please request materials or view the PDF data available for download.

The sheets used at civil engineering sites are important temporary materials that not only stabilize footing but also relate to the impression of the site and the ability to make proposals. While traditional steel sheets are common, their heavy weight makes transportation, installation, and removal cumbersome, making it difficult to differentiate between sites. The Hyper CLT sheet is a civil engineering CLT material that utilizes wood CLT. As a sheet with the texture of wood, it can be used in a wide range of civil engineering sites, including temporary roads, access routes, heavy machinery scaffolding, material storage areas, and pedestrian pathways. The 5×10 sheet weighs about 230 kg, and the 5×20 sheet weighs about 460 kg, making them lightweight and easy to handle even with small machinery, which helps reduce construction burdens and labor requirements. Additionally, due to the unique properties of wood, it can help suppress glare, reduce noise, and promote environmental considerations, making it easy to use for creative proposals and improving site evaluations in public works. It features a different appearance and functionality compared to iron sheets, contributing to site creation that takes into account landscape and working environments. Recommended for companies considering alternatives to steel sheets, it is registered as a Ministry of Land, Infrastructure, Transport and Tourism NETIS technology "TH-250021-A." We also accept consultations for implementation tailored to site conditions and requests for materials. Please make use of it for differentiation in public works and private civil engineering projects. We can accommodate sites both within and outside Okayama Prefecture. Please feel free to consult with us.

Under the floor and in the attic... "Invisible spaces" are being reconsidered now The environment surrounding the housing industry has changed significantly in recent years. Rising lumber prices, increases in equipment costs, a shortage of skilled workers, and prolonged delivery times are all contributing factors. These changes are not temporary; they are becoming established as structural changes within the entire housing industry. Furthermore, in recent years, the global surge in resource prices, the depreciation of the yen, and rising logistics costs have compounded the situation, leading to an overall instability in housing-related materials. The environment where it was once taken for granted that "necessary materials would be readily available when needed" is no longer a certainty. Additionally, the construction and equipment industries continue to face a serious labor shortage. In particular, the aging of veteran craftsmen who support the field is progressing year by year, while securing young talent is not easy. As a result, situations such as difficulty in scheduling construction dates, longer waiting periods before construction, and limited availability of contractors in certain regions are increasingly common nationwide. In the housing industry, there is now a growing sentiment that "construction plans cannot be made with the same sense as before," whether for new builds or renovations.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding methods for repairs 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 at all. Repairs can be made even 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 or download the catalog.
