In civil engineering sites such as mountainous areas and construction sites, it may be necessary to use wooden boards on slopes or inclined access roads. Hyper CLT boards are civil engineering materials utilizing wood CLT, which can be laid not only on flat ground but also on sloped terrain. They can be used for temporary roads, access routes, heavy machinery entry paths, and measures against muddy conditions, creating a driving environment that takes advantage of the unique surface characteristics of wood. The 5×10 board weighs approximately 230 kg, and the 5×20 board weighs about 460 kg, making them lightweight and easy to install and remove even with small machinery, which is a notable feature for maneuverability in narrow sites. This wooden board is registered as a technology under the Ministry of Land, Infrastructure, Transport and Tourism's NETIS system as "TH-250021-A," and can also be utilized for safety measures and innovative ideas in public works.

Metal cracks are one of the concerns in equipment maintenance operations. Repairs using conventional welding methods can alter the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" or "secondary damage." Hinode Waterworks 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 performed even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized.

● 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.

● To determine the sealing and waterproofing of sealed products based on pressure changes, it is not necessary to conduct tests that involve spraying water on the product or immersing it in water. ● Once the product is placed in a dedicated fixture within the inspection device, waterproofing can be quantitatively confirmed through automatic measurement. ● The target product size is W 300 × D 210 × H 100 mm or smaller. ● The target products include automotive cameras, smartphones, ECUs, small motors, and other packaging containers, and are effective for any products that require confirmation of sealing, waterproofing, and airtightness. ● For product specifications and details, please contact us.

The inspection targets of the "MSX-7003 series" are relatively large electronic devices. 【Inspection Targets】 - LED - Optical devices - High-frequency devices - Power semiconductors - IR sensors - Gyro sensors - Angular velocity sensors - Electrolytic capacitors, etc. The transport system is designed based on "pallet to pallet" to accommodate various types of work. The following three processes are performed automatically by the airtight inspection device: - Helium bombarding - Gross leak test - Fine leak test For packaged products smaller than 10 mm on each side, the work is set up using pallets or trays, followed by helium bombarding ↓ Then transported to the leak test process through high-speed handling ↓ Going through a continuous process from the gross leak test to the fine leak test ↓ And finally, discharged onto a pallet through high-speed handling. It also supports inline operations (the height of the pass line is 940 mm). Please watch the YouTube video from the link below.
