Thank you for visiting the 34th Plant Show INCHEM TOKYO 2021 from November 17 (Wednesday) to November 19 (Friday) 【Nihon Diavalve】.

Easy with 90-degree operation! Prevents over-tightening and damage! "I'm worried if it's securely tightened..." We solve this kind of concern.

The "BQL400NB model" is a rapid opening and closing type handle diaphragm valve from BioClean. While the standard handle version requires about 5 turns of operation (for DN50), the rapid opening and closing handle allows for a very simple operation of just "opening and closing by 90 degrees." The valve's open and closed status can be clearly seen from a distance based on the handle position. Additionally, it has achieved a lighter and more compact design compared to conventional products. Please try the easy operation and stable closing performance of the 90-degree rotating lever handle. 【We solve the following problems!】 ■ Excessive opening and closing torque → Reduction is possible, greatly contributing to labor savings. ■ Want to check the opening and closing status from a distance → The valve's open and closed status can be clearly seen from a distance based on the handle position. ■ Damage caused by over-tightening the valve → Only the minimum necessary operation is required. This prevents damage and extends lifespan. *For more details, please refer to the PDF materials or feel free to contact us.

A system for driver terminals has been realized through API integration, promoting the optimization of the delivery process and improvement of services to customers. Seino Information Service Co., Ltd. and Briskola Co., Ltd. announce that they have adopted Briskola's full lifecycle API management product "BAMs Series" for the construction of a system utilizing APIs and the management of API connections with various business applications for driver terminals, aimed at improving delivery efficiency and achieving digitalization of logistics for Seino Transportation Co., Ltd. and transportation groups nationwide. By implementing Briskola's "BAMs Series" for API management in the delivery management system constructed through API integration, we will focus on responding to the expected increase in the number of API calls due to the anticipated increase in terminal numbers, as well as ensuring stable system operation and preventive detection. This will lead to improved operational efficiency for drivers and the provision of high-quality services to customers sending and receiving packages.

In this case study, we have received cooperation from Obayashi Corporation and Sankyu Inc., leaders at the forefront of the construction and logistics industries, to introduce their specific initiatives regarding "early detection of heatstroke risk" and "ensuring worker safety." Additionally, we have published an interview article with Obayashi Corporation, who contributed to the development of "GenVital LTE," as a "development story." As heatstroke risk has become a social issue, we encourage everyone in companies working on improving on-site productivity and safety measures for workers to read this for insights. GRIFFY will continue to contribute to creating safer and more comfortable working environments through DX solutions, including "GenVital LTE." ◾️ Obayashi Corporation (case study) ◾️ Sankyu Inc.

We conducted an RTK accuracy verification of the GNSS reference station (Hi-Target Vnet6plus receiver + choke ring antenna) installed at our company building. Generally, with a single-frequency GNSS, once the baseline length exceeds 10 km, it becomes impossible to consider the path through the ionosphere as the same, and the difference in ionospheric delay becomes a significant source of error. By using dual-frequency GNSS, it is possible to correct the delay based on the differences in delay caused by the frequency of the radio waves; however, it is still said to be effective only up to about 10 km. Why is that? We have published the verification results on our blog.
