• Surveying Office

The collapse simulation software will be input and verified by local businesses. We support the creation of homes that can be lived in continuously.

Wallstat is software that creates an analysis model of wooden houses, applies seismic motion to the building just like in a shaking table experiment, and numerically analyzes the collapse process up to complete failure, allowing for visualization of seismic performance on a computer. In the residential business, we offer input and verification services for Wallstat. "I downloaded Wallstat but can't input data." If you are in this situation, please feel free to consult with our residential business.

We will conduct a "preliminary survey of asbestos-containing building materials" that is necessary before carrying out demolition and renovation work, focusing on wooden single-family houses.

There are four points regarding the preliminary asbestos survey for residential businesses. 1. Nationwide survey capability Asbestos-containing building material surveyors will conduct surveys nationwide. *As of October 2023, surveys conducted by asbestos-containing building material surveyors are mandatory.* 2. Fast delivery within one week Delivery will be made within one week from the survey date. This includes document surveys based on design documents and "deemed containing surveys" conducted on-site. *Delivery times may vary if sample collection and analysis are involved.* 3. Sample collection and analysis available Sample collection should be conducted on-site with your presence. Delivery times will be communicated based on the number of collection points. *Analysis is limited to samples collected by our company.* 4. Electronic reporting based on the screen Report *Asbestos preliminary survey result reporting system* For demolition and renovation work of a certain scale or larger, electronic reporting of survey results is required. *To use the asbestos preliminary survey result reporting system, prior issuance of a G Biz ID is necessary.*

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.

Seven Corporation has begun research and development related to rust prevention, aiming to expand the functionality of the natural multifunctional aqueous solution "SEA'S 7." This research is being promoted as a collaborative study with the Industrial Technology Research Institute. In recent years, the manufacturing industry has been seeking technologies that balance environmental impact reduction and improved work safety, making rust prevention measures after cleaning a critical issue. This research includes corrosion evaluation using metal test pieces, measurement of weight changes, and durability tests in a circulating water environment, advancing the understanding of rust prevention mechanisms and performance evaluation. In the future, we aim to develop a next-generation SEA'S 7 that incorporates rust prevention functionality in addition to cleaning, disinfection, and deodorization, contributing to the efficiency of manufacturing processes and the reduction of environmental impact.
