Gas sensors using microheaters achieve safer and more efficient gas detection through high sensitivity, low power consumption, and compact design.

Our company is working on a new technology that utilizes microheaters based on semiconductor technology, moving away from the traditional platinum coils used in contact combustion gas sensors. Microheaters can achieve instantaneous temperature increases and high sensitivity detection due to their high reactivity, while also being energy-efficient due to low power consumption. Traditional gas sensors required a large power consumption and had to be configured for AC power supply. Gas sensors utilizing microheaters can operate for long periods on battery power.

The contact combustion-type gas sensor is a sensor that detects gas concentration by utilizing the heat generated during the combustion (oxidation reaction) of flammable gases.

Contact combustion-type sensors are widely used for the detection of combustible gases such as methane and propane. They are also commonly used as gas leak detectors in industrial and household settings, playing a crucial role in safety measures.

Our company has developed a system that enables simple and highly accurate measurement of the calorific value of biogas, and we are conducting demonstration experiments for it.

By focusing on the methane gas contained in biogas and measuring its concentration, we can indirectly determine the calorific value. For measuring methane gas concentration, we use an infrared gas sensor that utilizes the infrared absorption wavelength of gas molecules. This allows for rapid and highly accurate measurement of gas concentration even in high concentration areas. It is equipped with a compact and inexpensive pressure reduction and flow rate stabilization system, enabling the extraction of process gas and real-time data acquisition. An example of methane concentration measurement data can be downloaded from the catalog. *For more details, please feel free to contact us. *Please note that we cannot reply to g-mail addresses on our company system.

Utilizing the principle of "uchimizu," we create cold water from heat. We will explain that technology (mechanism) in an easy-to-understand manner.

In normal physical phenomena, it is considered difficult to directly create cold water from heat. Heat is a form of energy in an object, and since energy is conserved, it is necessary to convert the heat into another form of energy in order to cool it down. Because heat naturally flows from high temperature to low temperature, it is possible to cool an object by removing heat. For example, it becomes possible to create cold water by extracting heat from a heat source through water and transferring it to another object to lower its temperature.

Specifically, I will explain the process of making cold water from heat.

First, a low-temperature, low-pressure gas-liquid mixed refrigerant (water and water vapor) enters the evaporator. Inside the evaporator, which is in a near-vacuum state, the boiling point of water at 100°C is reduced to 7-10°C, allowing the refrigerant (water) to boil and turn into water vapor by absorbing heat from relatively warm water in the chilled water piping. The water vapor is drawn into the absorber, similar to the suction side of a vapor compression refrigeration cycle compressor. The water vapor is absorbed by the absorbent "lithium bromide" and is pumped into the regenerator. In the regenerator, the mixture of refrigerant and absorbent is heated to separate it back into the original water vapor and absorbent, with the absorbent returning to the absorber and the water vapor being sent to the condenser. There are methods for adding heat in the regenerator, including combustion using fuels such as gas or oil, or using steam or hot water. The refrigerant, which has returned to water after losing heat in the condenser, is depressurized in the expansion device and flows back to the evaporator, repeating the cycle.

<Title> Development of Gene Expression Control Technology through RNA Hacking In the latest presentation paper, we have utilized Abby. Associate Professor Yosuke Katsuta from Kumamoto University Graduate School of Advanced Science and Technology, Analytical Chemistry Laboratory (also co-founder of StapleBio), will be giving a presentation in an online seminar. He is working on the development of RNA hacking technology aimed at controlling gene expression by utilizing short nucleic acids named Staple to change the higher-order structure of target mRNA. He will present the latest data focusing on the results of cell experiments and animal experiments in the development of this technology.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create 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! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.
