With the advancement of the information society, there is increasing demand for devices with lower power consumption, higher speed, and smaller size. However, conventional semiconductor integrated circuits (CMOS) are approaching physical and technological limits in scaling and integration density. This is mainly because charge-based devices inevitably suffer from heat generation and signal delay due to electron transport. 　To overcome this, researchers have successfully demonstrated the proof-of-concept of information transmission technologies and logic devices that utilize spin waves—specifically magnons propagating in a magnetic insulator such as yttrium iron garnet (YIG)—as information carriers, thereby eliminating the need for electron transport. 　This invention relates to an address encoder/decoder circuit that employs magnons and uses a ring-shaped interference region to convert complex input signals into corresponding output addresses.

To simulate quantum annealing on classical computers, Simulated Quantum Annealing (SQA) based on the Ising model has gained attention. The inventors have developed a parallel algorithm that enables multi-level parallel processing of SQA with a fully connected Ising model, implemented on a Field Programmable Gate Array (FPGA) (related work [1]). 　This invention supports sparse coupling models and proposes an algorithm that allows for faster analysis of classical spin systems based on the Ising model. This makes it possible to execute SQA at practical speeds using FPGA acceleration.

The electrochemical CO2 reduction reaction (CO2RR) process, in which CO2 is electrochemically converted, is attracting attention as a promising CO2 reduction method. However, the conventional method has a problem of low energy efficiency. The inventor has found that it is possible to improve the efficiency of the CO2RR process by utilizing a high-temperature high-pressure water environment called a hydrothermal conditions. When electrolysis is carried out in high-temperature high-pressure water at 150℃ and 100 atm pressurized with CO2, the high diffusion coefficient and solubility of CO2 in the water facilitating efficient CO2 supply to the electrode, and the energy efficiency is significantly enhanced. Additional assessment has shown that it is possible to synthesize "carbon-negative" basic chemical product (methanol), in which the amount of CO2 absorbed exceeds the amount of CO2 emitted, by leveraging low-temperature waste heat from industrial sources and renewable electricity.

■Introduction of Tohoku University Technology (T11-045) In order to grasp the state of health, biological components (blood sugar, lactic acid, etc.) are measured by blood sampling. However, since continuous measurement is difficult and invasive, the burden on the user is large. Therefore, the present invention provides a biological component measuring sensor which can measure biological components in real time for a long time and does not cause pain to the user. 　Specifically, a probe for measuring biological components has been developed which collects subcutaneous tissue fluid like dialysis by applying special processing to an ultra-fine needle inserted into the skin. A micro reflux needle with a channel covered with a perforated membrane on the surface of the metal needle is inserted and placed in the skin, and reflux fluid (physiological saline) is circulated through the channel. Since a substance in the skin tissue enters the reflux fluid through the hole in the channel due to concentration diffusion (osmotic pressure), the substance is flowed outside the body and the blood concentration is estimated from the concentration in the reflux fluid measured by a sensor installed outside the body. 　The present invention enables non-invasive, low-pain continuous measurement equivalent to blood sampling simply by attaching a micro-needle to the skin. *Please refer to the PDF file for related patent (T25-009).

Since ammonia does not emit carbon dioxide when burned, its use is expanding as an alternative fuel to fossil fuels. However, the combustibility of ammonia is inferior to that of fossil fuels, so some combustion support method to promote the oxidation reaction of ammonia is required for the development of combustors for ammonia. As ammonia combustion support methods, intense preheating and the use of powerful igniters have been devised, but there are problems such as the need for high thermal energy, the increase in material cost for high thermal load, and the decrease in durability. Therefore, a low-cost and simple method has been required. The present invention has found that the combustibility of ammonia can be easily promoted only by irradiating deep ultraviolet light. As shown in FIG. 1, ammonia is excited by deep ultraviolet light, and the excited ammonia is decomposed into active radicals (NH₂ and H) to promote combustion reaction. Since deep ultraviolet light emission from a hydrogen flame is very weak, the energy required for deep ultraviolet light irradiation by an electric device is low, and the present invention is a simple and low-cost ammonia combustion supporting method.
