Notice of Participation in the "New Manufacturing and New Services Exhibition for Small and Medium Enterprises" from December 14 (Wednesday) to December 16 (Friday), 2022.

Speedy cleaning with highly effective chlorine dioxide gas! Safe to use with high-precision concentration measurement and control.

We offer a "Space Disinfection System (Weraser Series)" that combines a wagon-type disinfection device that generates and releases chlorine dioxide gas with a gas concentration meter. *We can also respond to requests for the prototype and development of chlorine dioxide gas generation devices (with concentration adjustment functions). Using chlorine dioxide gas, which has excellent disinfection power and high diffusibility, disinfection is completed in a short time. This is a professional-grade disinfection system that utilizes our technology developed for disinfection systems for major pharmaceutical factories. 【Features】 ■ High disinfection effectiveness prevents bacterial growth and suppresses odors ■ Intelligent function manages the diffusion of chlorine dioxide gas ■ Collects chlorine dioxide gas to below 0.1 ppm using HEPA and activated carbon filters *In addition to the product catalog, we are currently offering materials that explain related systems and chlorine dioxide. You can view them via [PDF download]. Please feel free to [contact us].

Steripower (hypochlorous acid aqueous solution) is used. It is sprayed in a mist form of 7μm with a special nozzle. The micro-particles float in the air for a long time, enhancing the disinfection effect!

The droplet sprays sterilizing power (hypochlorous acid aqueous solution) from a movable dome, creating a safe space that has been disinfected. The main body features a stable trapezoidal wagon style that excels in functionality. Thanks to a special nozzle, the chemical solution is atomized into a mist of 7μm, allowing micro-particles to remain suspended in the air for an extended period, enhancing the disinfection effect. The adjustable dome allows for angle adjustments of the nozzle, enabling changes to the spray angle of the disinfectant (3 levels). (Note: Nozzle removal is an optional feature.) The intermittent operation function allows for savings on the chemical solution and enables long hours of operation. Equipped with multifunctional features such as deodorizing, air purification, and disinfection! *For more details, please download the PDF or feel free to contact us.

The command center for space disinfection! Measurement of gas to emission completed in 18 seconds!

The gas in the sterilization room is drawn into the measurement cell, and the ultraviolet light from the ultraviolet light-emitting diode is received by a photodiode. Concentration conversion is performed. Before measuring gas concentration, a zero point measurement is conducted with fresh air, and a light filter is inserted for K-point correction. After these calibrations, the gas concentration is measured. The measured gas is then discharged. This operation can be completed in [18 seconds]! *For more details, please download the PDF or feel free to contact us.

Wagon-type disinfection device! Releases chlorine dioxide gas at 20 m/s! Quickly diffuses in the space for disinfection. Communicates with a meter via wireless to control gas concentration.

The device generates chlorine dioxide gas from the supplied chlorine dioxide water and releases it from the arch. The supplied chlorine dioxide water is activated by a variable bubbling function to produce chlorine dioxide gas. The concentration of the generated gas is determined by an external measuring device and is released until it reaches the pre-set spatial gas concentration. The device and the measuring instrument are connected via a 2.4GHz radio wave (second-generation low-power data communication system), and the diffusion of chlorine dioxide gas is managed by the intelligent functions of both the device and the measuring instrument to enhance the disinfection effect in the room. After a set exposure time determined by the fumigation time setting function, gas recovery is performed. The rear HEPA filter and activated carbon filter recover and absorb chlorine dioxide gas to below 0.1 ppm. In this recovery mode, dust is also removed, and clean air is released. *For more details, please download the PDF or feel free to contact us.*

We will be exhibiting at "JAPAN SHOP 2026," which will be held at Tokyo Big Sight from March 3 (Tuesday) to March 6 (Friday), 2026.

**Lecture Content** "Characteristics of Soil Engineering and Troublesome Issues Anticipated in Design and Construction" (Scheduled Time: 15:00–16:00, 60 minutes) In our disaster-prone country, soil engineering, particularly embankments, has led to large-scale ground disasters due to earthquakes and heavy rainfall, resulting in significant damage. In this lecture, we will explain why soil engineering is vulnerable to rain and earthquakes from a geotechnical perspective, as well as discuss countermeasures for special soils and soft ground, which are treated as troublesome soils in design and construction. Lecturer: Masahiro Okamoto Consultant, Koyo Daiichi Consultants Co., Ltd. Tokyo Branch

Our company will be exhibiting at the "AI and Artificial Intelligence EXPO [Spring]" held at Tokyo Big Sight. This exhibition will showcase a variety of services related to AI, including deep learning, machine learning, edge AI, natural language processing, LLM, image and voice recognition, and conversational AI. We will also introduce various solutions utilizing AI from our company. Exhibited Products: - Product appearance inspection solution for the manufacturing industry: 'AIJO Check AItem' - AI rebar shape measurement system: 'AIJO Reinforcement King -AIJO HiKing-' - AI monitoring solution: 'AIJO Site Monitor' - Safety gear inspection before work: 'AIJO Safety' and more.

The sales department is the face of the company, as it has the most contact with customers (prospects) and builds up performance. However, even in this era where the utilization of digital and AI is being emphasized, know-how such as successful cases and efficient business practices has become personalized, resulting in many sales departments still facing challenges in improving performance and productivity. Have you ever experienced any of the following concerns regarding your company's sales activities? - You want to strengthen new orders, but you are overwhelmed with existing customers and projects. - Prospect and project information is managed individually by sales representatives, making it difficult to grasp the accurate amount of information and actions for the entire department. - You have introduced SFA tools or MA tools, but they are not being utilized. - You are considering the division of labor in the sales process but are unsure how to proceed with personnel allocation, business design, and the establishment of evaluation systems. In this webinar, we will provide hints for solving these issues and introduce successful cases, particularly focusing on the often-cited challenge of "acquiring new projects."
