Cadmium Eel is a screening kit that can quickly measure the cadmium concentration in rice. Typically, measuring cadmium concentration in rice involves instrumental analysis such as atomic absorption spectroscopy, which has issues such as high equipment installation costs and the need for specialized technicians. To address these problems, a highly sensitive antibody that specifically detects cadmium has been developed, leading to the creation of the Cadmium Eel kit based on the principle of immunochromatography, which is rapid, highly accurate, and low-cost. 【Features】 - Easy operation: No special skills are required, and measurements can be taken with minimal training (operating procedure video included). - Rapid: Results for 20 rice samples can be determined in about 90 minutes. - High accuracy: Comparable precision to instrumental analysis. - Low cost: Low equipment installation costs. - Usable anywhere: Requires only the space of a standard desk in a regular room. *This kit is designed to determine whether the cadmium concentration in rice meets the shipping standards (Food Sanitation Act: 0.4 mg/Kg or less). Rice with cadmium concentrations close to the standard value will require re-testing through instrumental analysis. It is recommended for farmers and businesses that want to regularly test their own rice and confirm safety on-site. Please watch the product introduction video via the YouTube link.

"Measurement of ion flow charging voltage" refers to measuring the charging voltage generated by the ion flow charging phenomenon near the ground under a DC transmission line. The ion flow charging phenomenon refers to the process where molecules in the air are ionized by a high voltage applied to an electrode, and the resulting ions move to impart charge to other objects. It is possible to measure the ion flow charging voltage under a DC transmission line as a self-inspection and understand the electrical environment beneath the line. 【Examples of Achievements】 ■ Measurement Items and Conditions - Received a request to measure the ion flow charging voltage under a DC transmission line and conducted continuous measurements (at 30-second intervals) over the course of one year. - In addition to the charging voltage, meteorological data such as local temperature, humidity, wind direction, wind speed, and rainfall were also collected. ■ Submitted Data - Narrowed down the analysis targets based on selected conditions such as weather and wind speed. - Created a cumulative frequency distribution based on the measured values of the charging voltage.

Wind tunnel experiments and environmental assessments refer to one of the atmospheric dispersion prediction methods established by the Environmental Impact Assessment Act. This involves placing models of terrain and structures inside a wind tunnel to recreate air flow and conduct experiments to predict the dispersion of exhaust gases released from power plants and waste incineration facilities (cleaning plants). This method is described in the "Guidelines for Environmental Impact Assessment Related to Power Plants," which serves as a guideline for implementing environmental assessments issued by the Ministry of Economy, Trade and Industry. By precisely controlling the temperature and flow velocity of the airflow within the wind tunnel, it is possible to replicate the actual atmospheric flow conditions and measure the behavior of gases and the concentration of smoke dispersion. **Applications** - Airflow analysis and dispersion analysis for various power plants, including thermal, nuclear, and geothermal. - Atmospheric environmental impact assessments in urban areas (such as decentralized power sources and urban warming effects). - Dispersion conditions of exhaust gases released from incineration facilities (cleaning plants). - Visualization experiments of flow fields around modeled buildings. **Features** - Precise reproduction of "temperature distribution, airflow distribution, and airflow turbulence" in the atmosphere. - Visualization of flow fields using smoke and lasers. - Capability to address complex structures that are difficult to replicate in simulations. *Please feel free to contact us through our company website.*

A water-oil insulated tube is a type of insulating tube used in insulation breakdown tests to assess the aging condition of CV cables that have been removed from actual power facilities. This tube is inserted into the cable terminals and filled with water and oil to relax the electric field. The purpose of this test is to apply alternating high voltage to the removed CV cable and cause insulation breakdown in the effective electrode part (XLPE). However, at the cable termination (terminal part), the equipotential lines and electric field lines become skewed, concentrating the electric field, which leads to breakdown occurring near the outer conductor of the terminal. By using the "water-oil insulated tube" to fill it with water and oil, the stress of electric field concentration at the terminal is alleviated, and the potential gradient becomes gentler, allowing for an increase in voltage up to the point where insulation breakdown occurs in the effective electrode part. Our company has a long history of involvement in the insulation breakdown testing and terminal processing of removed CV cables (3.3kV to 22kV) as a partner of research institutes related to power. Based on our experience and technology related to this test, we can design and manufacture water-oil insulated tubes according to cable diameter and voltage. Recommended for those who: - Want to observe water tree degradation phenomena - Want to understand the aging condition of CV cables.

**Overview** We will implement and supervise the corrosion prevention measures developed by the Central Research Institute of Electric Power Industry (CRIEPI) to protect the boiler water-cooled pipes and superheaters of coal-fired power plants (including oil-fired power plants) from sulfide corrosion and high-temperature corrosion, using a coating (patent registration number 5110608). This can be completed in a short period even if there is no time for thermal spraying or build-up welding. (A licensing agreement has been concluded with CRIEPI.) - CRIEPI has focused on the low reactivity of titanium oxide and sulfur, and has developed a composite film with excellent gas barrier properties. - In approximately two years of verification on actual coal-fired boiler equipment, corrosion was confirmed to be reduced to less than one-fourth compared to untreated areas (CRIEPI report: Comprehensive Report M04 (2015)). - The high-temperature coating addresses high-temperature corrosion (CRIEPI report M18004).

• Special Construction Method

The test resistance load device is intended for use in power conditioners for solar power generation systems, among others, to adjust the current balance during standalone operation prevention function tests or as a load for preventing reverse current. The maximum load capacity is 21.8 kW, which can accommodate up to five units in parallel operation for a typical household power conditioner (equivalent to 4 kW). 【Features】 ■ It is possible to switch between three-phase and single-phase according to the test voltage. ■ The load capacity increments are fine, with a minimum of 10 W (in single-phase), allowing for precise current balance adjustments. ■ In tests using three-phase power, the load for each phase can be set individually, enabling the creation of load imbalance conditions. ■ As a safety mechanism to prevent resistor burnout, two mechanisms are installed: the load will not engage unless the cooling fan is operational, and the power will be forcibly cut off if the resistor temperature exceeds a certain level. ■ Switches are available in two patterns: wired and wireless. ■ The wired switch comes with a 10 m cable, which can be extended up to 20 m with an extension cable. ■ The wireless switch is limited to the communication range of the wireless LAN, but distance extension is possible through the use of a relay.
